RTK Premium is our flagship network RTK service. RTK Core delivers the same accuracy on a single network, without redundancy or a service level. RTK Access uses PPP-RTK for horizontal positioning where centimetre-level vertical accuracy is not needed. RTK Seas covers marine work. Rinexlab, IoT SIMs, the SDKs and API, and the XYZ Platform complete the range. ### RTK services compared | Product | RTK Premium | RTK Core | RTK Access | | ---------------------------- | ------------------------------------------------------------------------------------------------------- | --------------------------------------- | -------------------- | | Positioning method | Network RTK | Network RTK | PPP-RTK | | Accuracy in a fixed solution | 1 to 2 cm horizontal, sub-3 cm vertical | 1 to 2 cm horizontal, sub-3 cm vertical | 3 to 7 cm horizontal | | Correction sources | Redundant sources in every Eligible Area, with smart failover | One network | PPP-RTK service | | Service level | 99.9% monthly availability in Eligible Areas, with a refund of the monthly fee when a month falls short | Best effort | Best effort | | Support response | 2 hours | 4 hours | 24 hours | Support response times apply during business hours. Accuracy figures assume good GNSS conditions; see [Accuracy expectations](/learn/accuracy-expectations) for what affects them. ### RTK Premium RTK Premium is built for survey-grade work where a dropped correction stops the job. In every Eligible Area, redundant correction sources serve your location, with smart failover when a network drops, and the service level commits to 99.9% monthly availability. The [coverage map](https://coverage.premium-positioning.com) shows which areas are served by redundant sources, and the [Service level agreement](/service-level-agreement) sets out the measurement, the exclusions and the refund scale. ### RTK Core RTK Core delivers the same accuracy as RTK Premium from a single network. There is no failover: if that network drops, corrections stop until it returns. RTK Core runs on a best-effort basis, with no availability commitment, and support responds within 4 hours. ### RTK Access RTK Access uses PPP-RTK to deliver 3 to 7 cm horizontal accuracy. It is designed for horizontal positioning, for example robotics, automation and mapping, and does not carry a vertical accuracy figure. For centimetre-level heights, use RTK Premium or RTK Core. Redundancy, L-band delivery and a 2-hour support response are available as options. ### RTK Seas RTK Seas is our marine service. It combines network RTK along the coast, PPP-RTK nearshore and PPP offshore, for 2 to 10 cm accuracy in three dimensions. The service level commits to 99.0% monthly availability, and support responds within 2 hours. ### Choosing an RTK service * Downtime costs you money, or you need a written service level on land: RTK Premium. * You need centimetre accuracy, vertical included, and can accept best-effort availability: RTK Core. * Your application needs horizontal position only: RTK Access. * You work at sea: RTK Seas. The [comparison guide](/learn/how-to-compare-correction-services) lists the questions to ask of any correction service. ### Rinexlab Rinexlab is our post-processing service. You upload static or kinematic GNSS observations, and Rinexlab provides the reference data and computes the positions. See [Rinexlab](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=products#rinexlab) on our website. ### IoT SIMs Premium Positioning IoT SIMs give a receiver, controller or machine its own data connection, so it does not depend on a phone or hotspot. Each SIM can use more than one operator in most countries, with smart failover when a network drops, and data is pooled across the SIMs in your fleet. RTK corrections use roughly 100 to 300 MB a month in normal field use; a device that streams around the clock uses more. See [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=products#iot-sims) on our website. ### SDKs and API Our SDKs and enterprise API build RTK Premium corrections into your own product or platform. See [SDKs and API](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=products) on our website. ### XYZ Platform RTK Premium is delivered through the XYZ Platform. It is where you manage subscriptions and devices, see the live status of each session, and keep a session record for each device. [Sign in to the XYZ Platform](https://rtkpremium.xyz/sign-in). ### Pricing and trial Prices depend on fleet size, term and region. [Request pricing](https://www.premium-positioning.com/pricing?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=products) for your use case, or [start a 14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=products) to test on your own equipment. ### FAQ What is the difference between RTK Premium and RTK Core?

Which products carry a service level? RTK Premium, at 99.9% monthly availability in Eligible Areas, and RTK Seas, at 99.0%. RTK Core and RTK Access run on a best-effort basis. Does RTK Access give vertical accuracy? RTK Access is designed for horizontal positioning and does not carry a vertical accuracy figure. Use RTK Premium or RTK Core for centimetre-level heights. How do I reach support? Email or call +31 85 0606 338. Support runs on business days from 09:00 CET to 17:00 ET. # Service level agreement RTK Premium and RTK Seas service levels: 99.9% and 99.0% monthly availability, refunds of the monthly fee, exclusions, support response times and Eligible Areas. Premium Positioning commits to at least 99.9% monthly availability of the RTK Premium correction stream in every Eligible Area, and at least 99.0% for RTK Seas. When a month falls short, you are entitled to a refund of the monthly fee for the affected accounts, on the scale under Remedy. This page summarises the Service Level Agreement, version 1.1 of 4 September 2026, which forms part of the contract under Article 10 of the Terms and Conditions. Where this page and the signed documents differ, the signed documents govern. ## Scope The service level applies to RTK Premium accounts operating in an Eligible Area and to RTK Seas accounts. It does not apply to RTK Access, RTK Core, RTK Premium outside an Eligible Area, trial accounts, post-processing services, connectivity services or platform access. Those are provided on a best-effort basis under Article 10.2 of the Terms and Conditions. The support response times below apply to every tier. ## Service level | Product | Monthly availability commitment | | ----------- | ------------------------------- | | RTK Premium | At least 99.9% | | RTK Seas | At least 99.0% | ## Availability Availability is the percentage of minutes in a calendar month during which the RTCM correction stream is available from Premium Positioning's casters for the Eligible Area concerned, as measured by Premium Positioning's monitoring. A minute counts as unavailable when no valid correction stream can be obtained from any of the redundant sources serving the Eligible Area. Availability is measured at the caster. It does not measure your connectivity, your equipment, or GNSS signal conditions at the rover. ## Measurement and evidence Premium Positioning's own monitoring records measure and evidence availability, and the records are kept for at least 24 months. Monthly availability for each Eligible Area is published on the status page. On request, you receive the monitoring record for the month and Eligible Area concerned. ## Exclusions The following are excluded from the measurement: * Planned maintenance announced at least five business days in advance, and emergency maintenance under Article 14.6 of the Terms and Conditions. * Suspension or deactivation under Articles 5.5 and 14.7. * Unavailability caused by you, or by equipment, connectivity or configuration under your control. * Force majeure, only where it affects the service despite the redundancy in correction sources, networks and suppliers maintained for the Eligible Area. The failure of a single correction network, carrier or other supplier is not excluded. Regional unavailability or degradation of GNSS constellations or signals, including jamming and spoofing, is excluded where it affects all sources serving the Eligible Area. ## Remedy | Availability in the month | RTK Premium refund of the monthly fee | RTK Seas refund of the monthly fee | | ------------------------------ | ------------------------------------- | ---------------------------------- | | Below 99.9% and at least 99.0% | 10% | None, commitment met | | Below 99.0% and at least 98.0% | 25% | 10% | | Below 98.0% and at least 97.0% | 50% | 25% | | Below 97.0% and at least 95.0% | 100% | 50% | | Below 95.0% | 100% | 100% | The monthly fee for an annually invoiced account is one twelfth of the annual fee. The refund is paid in cash to your account of record, or as a credit against your next invoice if you choose. For calendar months before monthly availability is first published on the status page, the remedy is a credit against the next invoice. The refund is the sole and exclusive remedy for a failure to meet the service level (Article 10.4). Claims must be made in writing within 30 days after the end of the month concerned (Article 10.6). ## Support response Premium Positioning responds to support requests within these times during business hours: | Tier | Response time | | ------------------------ | ------------- | | RTK Premium and RTK Seas | 2 hours | | RTK Core | 4 hours | | RTK Access | 24 hours | Business hours are 09:00 to 17:00 CET, Monday to Friday, excluding Dutch public holidays. If your contract is with Premium Positioning LLC, business hours are 09:00 to 17:00 Eastern Time, excluding US federal holidays. A response is a substantive reply from a support engineer, not an automated acknowledgement. These are response times, not resolution times. To reach support, email or call +31 85 0606 338. ## Eligible Areas Eligible Areas are the countries and regions shown as served by redundant correction sources on the [coverage map](https://coverage.premium-positioning.com) at the date of your contract. The coverage map is the authoritative list; the table below is indicative at the date of the SLA. In areas served by a single source, RTK Premium operates on a best-effort basis. | Region | Eligible (redundant sources) | Not eligible (single source, best effort) | | ------------- | -------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- | | Europe | EU and EEA member states, the United Kingdom and Switzerland, as shown on the coverage map | French overseas territories including Guadeloupe, and other territories shown single-source on the coverage map | | Türkiye | None | Single source | | Africa | None | South Africa: single source | | North America | United States and Canada, in the states and provinces shown as redundant on the coverage map | States and provinces shown single-source on the coverage map | | Asia-Pacific | Japan and Australia, as shown on the coverage map | Areas shown single-source on the coverage map | Premium Positioning may add Eligible Areas at any time. Removing one during the term of a contract is announced with 30 days' notice, and you may then terminate the affected accounts. ## Precedence Where documents conflict, the contract prevails over the SLA, and the SLA prevails over the Terms and Conditions (Article 2.6). # What is RTK What RTK is, how real-time kinematic positioning reaches 1 to 2 cm accuracy, and how RTK, network RTK and PPP differ. RTK, short for real-time kinematic, is a GNSS positioning technique that achieves 1 to 2 cm accuracy in real time. It works by correcting a moving receiver's position against measurements from a reference receiver whose position is already known, so that errors common to both cancel out. A phone or a basic GNSS receiver is accurate to a few metres at best. The signal is degraded on its way down by satellite orbit and clock errors and by delays through the ionosphere and troposphere. RTK removes almost all of that error and turns a few-metre fix into a centimetre one. ### How RTK works RTK relies on two things that ordinary positioning does not use. The first is the carrier phase. Instead of only reading the coarse code in the satellite signal, an RTK receiver measures the phase of the carrier wave itself, which has a wavelength of about 19 cm and can be tracked to the millimetre. The second is a reference receiver, called the base. Because the base sits close to the rover and sees the same satellites through nearly the same atmosphere, it measures nearly the same errors. The base streams those measurements to the rover, the rover differences them against its own, and the shared errors drop out. The hard part is the integer ambiguity: the receiver knows the fraction of a wavelength to the satellite but not the whole number of wavelengths. Resolving those integers is what separates a decimetre-level "float" solution from a centimetre-level "fixed" solution. Once the rover reports RTK Fixed, it typically positions to 1 to 2 cm and can record several positions a second. A fixed status is the receiver's own judgement, so check a known point when the result matters; see [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). For the fix to hold, the rover needs a clear view of the sky, a continuous correction stream, and an unbroken lock on the satellites. Pass under a tree or beside a building and the fix can drop to float until the receiver re-initialises. ### RTK, NRTK, and PPP A single base covers a few kilometres before the shared-error assumption weakens. Network RTK (NRTK) solves that by interpolating corrections from a network of permanent stations, so you carry only a rover and the base network does the rest. PPP and PPP-RTK take a different route again, using precise satellite data rather than a nearby base. Network RTK has its own page: [What is network RTK and VRS](/learn/what-is-network-rtk-and-vrs). ### How we provide RTK Premium Positioning delivers RTK and network RTK corrections as RTCM 3.x over the internet in 35+ countries, with 1 to 2 cm accuracy and 99.98% uptime over the last 12 months. Your receiver connects as an NTRIP client to receive the stream. ### FAQ How accurate is RTK? In a fixed solution, 1 to 2 cm horizontally in real time. What is the difference between RTK and GPS? GPS is one of the satellite systems an RTK receiver uses. RTK is the correction technique applied on top of GPS and the other constellations to reach centimetre accuracy. What do I need to use RTK? A GNSS receiver that supports RTK, a clear view of the sky, and a correction stream from a base or a correction network. What is a fixed versus a float solution? Float is the decimetre-level result before the integer ambiguities are resolved. Fixed is the centimetre-level result after they are. Ready to connect a receiver? See [Connect a receiver to our NTRIP caster](/set-up-and-connect/connect-a-receiver). # What is NTRIP What NTRIP is, how the caster, server and client work together, what a mountpoint is, and why your receiver sends a GGA heartbeat. NTRIP, short for Networked Transport of RTCM via Internet Protocol, is an open standard for streaming GNSS corrections over the internet. It is how the correction data reaches your receiver over a mobile connection, instead of over a short-range radio link. An NTRIP caster is the server at the centre of that stream. It collects correction data coming in from base stations or a correction network, and hands it out to the receivers that ask for it. When you connect a rover to receive RTK corrections over the internet, the caster is what it connects to. ### The three parts of NTRIP NTRIP has a simple shape, with three roles. The NTRIP server is the upstream side. It takes the raw correction data from a base station or a network engine and pushes it to the caster as a live stream. The NTRIP caster is the hub. It receives one or many incoming streams, checks who is allowed to connect, and distributes the right stream to each client. One caster can carry many separate streams at once. The NTRIP client is your receiver, or the software talking to it. It connects to the caster, signs in, and requests a stream. From there it receives a steady feed of corrections and applies them to its own measurements to compute a centimetre position. ### Mountpoints and the source table Each stream on a caster has a name, called a mountpoint. A provider often runs several, for example one per correction type or per region. Before you connect, your client can fetch the source table, which is the caster's published list of available mountpoints and what each one offers, then connect to the one that fits your receiver and your location. ### The GGA heartbeat For network RTK, the correction has to be tailored to where you actually are. To make that possible, the client sends its approximate position up to the caster as an NMEA GGA sentence when it connects, and then repeats it at intervals. That repeated message is the heartbeat. If it stops, the network can no longer generate a position-specific correction, so keeping it flowing matters on a moving platform. ### How NTRIP fits with our service Premium Positioning runs an NTRIP caster that streams RTK Premium corrections as RTCM 3.x, in ETRS89 in Europe, NAD83(2011) in the United States and NAD83(CSRS) in Canada. [Reference frames and constellations](/learn/reference-frames-and-constellations) lists the frame for every region. Any NTRIP-capable receiver can connect as a client to receive them. The exact host, port, mountpoint names, and sign-in details for your account live in the setup guide rather than here. ### FAQ What does NTRIP stand for? Networked Transport of RTCM via Internet Protocol. What is the difference between an NTRIP caster, server, and client? The server sends a correction stream up, the caster distributes it, and the client (your receiver) requests and receives it. What is a mountpoint? A named correction stream on the caster. You choose the one that matches your receiver and location. Do I need NTRIP for RTK? Only if you receive corrections over the internet. A local base can send corrections by radio instead, but NTRIP is how most network corrections are delivered. Why does my receiver send a GGA message? So the network knows roughly where you are and can generate a correction matched to your position. Ready to connect? See [Connect a receiver](/set-up-and-connect/connect-a-receiver). # What is network RTK and VRS? How network RTK and virtual reference stations deliver 1 to 2 cm corrections across a region without a local base station. Network RTK, or NRTK, is RTK that draws its corrections from a network of permanent reference stations rather than a single base. The network models the errors across a whole region, so a rover anywhere inside it receives a correction tailored to its position, and you carry only the rover. There is no local base to set up, and you get the same 1 to 2 cm accuracy as single-base RTK over a far larger area. A virtual reference station, or VRS, is the most common way those network corrections are packaged. The network synthesises the observations a base would have recorded right next to your rover, so the receiver computes a short baseline to a station that is not physically there. If you have not read it yet, [What is RTK](/learn/what-is-rtk) covers the base-and-rover technique that NRTK builds on. ### Why network RTK exists Single-base RTK leans on the rover and the base being close enough to see almost the same errors, so they cancel. That assumption weakens with distance: beyond a few kilometres from the base, the atmosphere over the rover is no longer the atmosphere over the base, and accuracy falls away. A network removes that limit. Permanent stations spread across a region feed their observations to a network engine. The engine interpolates the spatially correlated errors, the orbit and tropospheric (geometric) errors and the ionospheric (dispersive) errors, from the stations surrounding the rover, and streams back a correction matched to where the rover actually is. The result is a service that covers the whole network area, not a bubble around one base. ### How VRS works With a virtual reference station, the rover sends its approximate position up to the network. The network uses that position to build a synthetic set of observations, as though a base were standing a few metres away, and sends them down. From the rover's point of view this looks exactly like an ordinary short-baseline RTK connection, which is why VRS works with standard NTRIP receivers without anything special. This is also why the GGA heartbeat matters. The position the rover sends is what the network builds the VRS around, and it has to keep sending it so the correction follows the rover as it moves. See [Mountpoint selection and the GGA heartbeat](/troubleshooting/mountpoint-selection-and-the-gga-heartbeat). ### Other ways network corrections are delivered VRS is the most widely used, but it is not the only method. * FKP delivers area correction parameters that describe how the errors vary across the region as a surface, which the rover then applies to its own position. * MAC, the master-auxiliary concept, sends one master station's observations plus the differences measured at the auxiliary stations, and lets the rover compute its own correction with full control over the process. For most users the method is transparent: you connect to a mountpoint and receive corrections. Which method is in use is a network and receiver detail rather than something you choose point by point. ### How we provide network RTK RTK Premium runs on more than 7,500 base stations in 35+ countries, delivering NRTK corrections as RTCM 3.x at 1 to 2 cm accuracy, in ETRS89 in Europe. Any NTRIP-capable receiver can connect as a client to the COMMON mountpoint to receive them. See [Connect a receiver to our NTRIP caster](/set-up-and-connect/connect-a-receiver). ### FAQ What is the difference between RTK and network RTK? RTK uses a single base near the rover. Network RTK uses a network of permanent stations and delivers a correction tailored to the rover's location, so it works over a much wider area with only a rover. What is a VRS? A virtual reference station: synthetic base observations the network generates right next to your rover, so the receiver sees a normal short-baseline connection. Do I need my own base station for network RTK? No. The network is the reference, so you carry only the rover and a connection to the caster. Why does my rover send its position to the network? So the network can build the correction, or the VRS, around where you are, and keep it matched to you as you move. Is network RTK as accurate as single-base RTK? Yes, the same 1 to 2 cm class. Single-base accuracy falls off with distance from the base, while a network holds it across the area its stations cover, with some variation where stations are sparse or near the edge of coverage. # Accuracy expectations What accuracy to expect from RTK Premium in the field: 1 to 2 cm horizontal and sub-3 cm vertical in a fixed solution, and the conditions that affect it. In a fixed solution under good GNSS conditions, RTK Premium positions to 1 to 2 cm horizontally and sub-3 cm vertically. The conditions below decide whether you get that result on the day, so they are worth planning around. ### Accuracy across the network RTK Premium is network RTK on a virtual reference station model. The network models the ionospheric, tropospheric, and satellite orbit and clock errors from the reference stations around your rover, and builds a correction for where you are. Accuracy therefore depends far less on your distance to any one base station than it does with single-base RTK. It still varies with how closely the network's stations are spaced, which differs between networks and regions. See [What is network RTK and VRS](/learn/what-is-network-rtk-and-vrs). Near the edge of coverage, run a fix test on site before committing to a full day of work. ### Sky view * Best: open ground with no obstructions above about 15 degrees elevation. * Good: rural areas with scattered trees. * Challenging: near buildings or under partial tree canopy. * Poor: urban canyons, dense forest, and large metal structures. Multipath, where signals reflect off buildings, vehicles, or metal before reaching the antenna, biases the position even while the receiver reports fixed. See [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Data connection Corrections have to arrive in real time, so the stability of the data link matters. Use a stable 4G or 5G connection, and watch the correction age on the receiver. A few seconds is normal; a rising age points to a struggling link. ### Receiver and antenna A survey-grade or good mapping-grade receiver with a correctly measured antenna height gives the best and most repeatable results. A wrong antenna height adds the same vertical offset to every point. ### Heights RTK gives ellipsoidal heights. If you need height above sea level, apply a geoid model in your software. See [Ellipsoidal and orthometric heights](/learn/ellipsoidal-and-orthometric-heights). ### Getting the best results 1. Work with a clear view of the sky. 2. Use a stable mobile data connection. 3. Wait for a stable fixed solution before collecting points. 4. When a result matters, measure a known point and compare it with its published coordinates. ### FAQ How accurate is RTK Premium? In a fixed solution, 1 to 2 cm horizontally and sub-3 cm vertically under good conditions. How do I check the accuracy my service delivers? Measure a known point on site, or run a session on RTKTEST.com, which compares services against a surveyed point. See [Testing a correction service](/learn/testing-a-correction-service). Does accuracy drop as I move away from a base station? Far less than with single-base RTK, because the network builds the correction for your position. Accuracy still varies with station spacing, so near the edge of coverage or where stations are sparse, test on site first. Why is vertical accuracy lower than horizontal? All the satellites a receiver tracks are above the antenna, so the vertical component is less well constrained than the horizontal. This holds for all GNSS positioning, not only RTK. My receiver reports fixed but the position is wrong. Why? A fixed status means the receiver believes it resolved the ambiguities, not that it resolved them correctly. See [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). # Ellipsoidal and orthometric heights Why an RTK elevation can differ from height above sea level by tens of metres, and how to apply a geoid model to get orthometric heights. RTK Premium corrections give your receiver ellipsoidal heights by default. If you need height above mean sea level, known as orthometric height, apply a geoid model in your field software, rover, or GIS. ### Why your elevation can look wrong An ellipsoidal height is measured from a mathematical model of the Earth's shape, not from sea level. The difference between the two, called the geoid separation, can be tens of metres depending on where you are. A horizontal position that is correct to the centimetre can still show an elevation that looks far off if you expected an orthometric value. The offset is close to constant across a site, so every point is shifted by about the same amount. That pattern points to the height reference, not to the correction stream. ### How to get orthometric heights 1. Confirm which geoid model your project requires. The national mapping agency for your country publishes the official model. 2. Select that geoid model in your field software, rover, or GIS. 3. Measure a known control point and compare its height with the published value before relying on elevations. ### Heights and the antenna A wrong antenna height produces a similar symptom: the same vertical offset on every point. Check the antenna height entry before changing the geoid model. See [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### FAQ Why is my RTK elevation tens of metres off? The receiver is most likely reporting ellipsoidal height and you expected height above sea level. Apply the geoid model for your region. Does RTK Premium deliver orthometric heights? The corrections give ellipsoidal heights. Your software converts them to orthometric heights once you select a geoid model. My plan position is right but heights are off by a few centimetres. Where do I look? Check the antenna height entry first, then confirm that the geoid model and its version match what your project requires. For what affects vertical accuracy in the field, see [Accuracy expectations](/learn/accuracy-expectations). # How to compare correction services How to compare RTK correction services beyond accuracy: continuity when a source fails, visibility, proof of position, and a published service level with a remedy. Accuracy is the entry requirement: any survey-grade correction service should deliver centimetre positions in good conditions. The differences between services show on a bad day, when a correction source fails, a result is questioned, or a crew is waiting on a fix. Compare any service, including RTK Premium, on the four questions below. ### Continuity Does the fix hold when one correction source fails? A service that runs on a single source stops when that source stops. Ask how many correction sources serve your area, and what happens to your connection when one drops. ### Visibility When a fix drops, can you tell whether the problem is your equipment or the network? Ask whether you can see the status of each session yourself, rather than waiting for support to tell you. ### Proof Can you show where a device was, and with what correction, after the fact? Ask whether the service keeps a session record you can show a client or an auditor. ### Accountability Has anyone committed in writing to the service level? Ask whether the availability commitment is published, how it is measured, what the remedy is when it is missed, and how quickly support responds. ### Checklist for any provider * Is the availability commitment published, and what is the remedy when it is missed? * How many correction sources serve your area, and what happens when one fails? * Does accuracy hold across the coverage area, or depend on distance to the nearest base station? * Can you see the status of each session yourself? * Can you produce a session record for any device after the fact? * What is the support response time, and in which hours? Accuracy is the one question you can measure yourself. [Testing a correction service](/learn/testing-a-correction-service) shows how to compare services side by side against a surveyed point on RTKTEST.com, the open benchmark Premium Positioning runs. ### How RTK Premium answers | Question | RTK Premium | | -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Continuity | Each Eligible Area is served by redundant correction sources. Under the service level, a minute counts as unavailable only when no source can deliver a valid stream. | | Accuracy | Network RTK: 1 to 2 cm horizontal and sub-3 cm vertical in a fixed solution, with the correction built for your position from the surrounding stations rather than from one base. | | Visibility | The XYZ Platform shows the live status of each session, so you can see whether a device is connected and receiving corrections without waiting for support. | | Proof | The XYZ Platform keeps a session record for each device, which you can show a client or an auditor. | | Accountability | 99.9% monthly availability in Eligible Areas, a refund of the monthly fee on a published scale when a month falls short, and a 2-hour support response in business hours. See [Service level agreement](/service-level-agreement). | ### FAQ Is a low-cost NTRIP feed good enough for survey-grade work? It can be on a good day. The questions are what a dropped fix or a disputed result costs you, and whether anyone has committed in writing to the service level. Check the published service level and its remedy before comparing prices. What is the most important thing to check? Whether the service level is committed in writing, with a remedy when it is missed. # Testing a correction service Measure correction services against a surveyed point on RTKTEST.com, the open benchmark Premium Positioning runs: how a session works and how to read the result. Coverage maps and fix rates do not show how accurate a correction service is where you work. RTKTEST.com, the open benchmark Premium Positioning runs, measures it: it streams your services to a reference receiver at a surveyed point and compares every position with the known coordinate. ### How a session works 1. Choose the probe closest to where you operate. A probe is a fixed reference receiver at coordinates surveyed to sub-centimetre accuracy. 2. Enter the NTRIP details for up to three services: caster address, port, mountpoint, username and password. 3. Run the session. For 15 minutes the probe processes every stream from the same antenna and the same satellite observations, and computes one position per second for each service. 4. Read the results. They are sent to the email address you entered and stay private to it. Because every service sees the same sky, atmosphere and multipath at the same moment, a difference in the result comes from the correction service. Your credentials sign in directly with each provider's caster and are not stored. RTKTEST identifies a service by its caster address and mountpoint. ### What a session measures * Trueness: the average offset of the positions from the surveyed coordinate, in east, north and up. * Precision: how widely the positions scatter around their own average. * Fix availability: the share of the session spent in a fixed solution. * Time to first fix: how long each service took to reach a fixed solution. A composite score combines these, and the session record keeps the statistics behind it. The [RTKTEST methodology](https://www.rtktest.com/methodology) publishes the weights, the open-source engine and its configuration, and the raw data is archived, so any result can be recomputed. ### Testing RTK Premium Enter the credentials from your trial or subscription with these settings: * Caster address: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=testing-a-correction-service) to get your credentials. Every RTKTEST session also measures RTK Premium as a fixed reference service. Its figures appear in a separate block of the result, are never ranked against the services you chose, and are kept out of the public leaderboard. When you enter RTK Premium as one of your own services, it is ranked like any other. ### Reading the result * A large average offset with little scatter is a bias, not noise. It most often comes from a difference in reference frame or epoch. In North America, RTKTEST measures in NAD83(2011), epoch 2010.0, the frame RTK Premium delivers in the United States. See [Reference frames and constellations](/learn/reference-frames-and-constellations). * Scatter shows how repeatable a service is. Two services can hold the same average and still differ in how far single positions wander. * A session covers 15 minutes at one probe. Your own site differs in sky view, multipath and distance to the network's stations, so repeat the test on different days before you decide, and check a known point on site as described in [Accuracy expectations](/learn/accuracy-expectations). ### FAQ Who runs RTKTEST? Premium Positioning runs it. The methodology is public and versioned, every service is measured with the same engine and settings, and the raw data is archived so a third party can recompute any result. Does RTKTEST keep my NTRIP password? No. Your credentials sign in directly with your provider's caster and are not stored. Can I compare my current provider with RTK Premium? Yes. Enter both in the same session, and they are measured on the same probe over the same 15 minutes. Why does a service show a steady offset from the surveyed point? A large average offset with little scatter is a bias, most often a difference in reference frame or epoch. See [Reference frames and constellations](/learn/reference-frames-and-constellations). Is there a probe near me? The probe map opens when you start a session. Coverage depends on where suitable reference stations are available, so pick the probe closest to where you operate. # Reference frames and constellations The reference frame RTK Premium corrections are delivered in for each region, the satellite systems they support, and the correction stream settings. Coordinates are only useful in the reference frame your project works in. RTK Premium corrections are delivered in the regional frame listed below, and your field software transforms them into any national or local system your project requires. ### Reference frames by region | Region | Frame the corrections are delivered in | | ------------- | ------------------------------------------------ | | Europe | ETRS89, realisation ETRF2000, epoch 2010.0 | | United States | NAD83(2011), epoch 2010.0 | | Canada | NAD83(CSRS), epoch 2010.0 | | Hawaii | NAD83(PA11), epoch 2010.0 | | Japan | ITRF2008, epoch 2005.0 | | Australia | GDA2020, epoch 2020.0 | | Other regions | Contact support for the frame used in your area. | In the United States and Canada, ITRF is available on request. After setting up a transformation, measure a known control point before relying on the results. If every point is shifted by the same amount, the frame or the transformation is the first thing to check. See [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Why coordinates can be offset The size of a consistent offset usually points to its cause. | Consistent offset | Likely cause | | ------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | About 1 to 2 m horizontally in North America | A global frame such as ITRF or WGS84 mixed with NAD83 | | Several decimetres to about 1 m in Europe or Australia | A global frame at the current epoch mixed with ETRS89 or GDA2020 | | A few centimetres | A different realisation or epoch of the same frame, or the quality of the control points | | Tens of metres vertically | Ellipsoidal heights read as heights above sea level | | A steady vertical offset of a few centimetres | The geoid model or its version, or the antenna height | To measure a service's offset against a surveyed point, see [Testing a correction service](/learn/testing-a-correction-service). For heights, see [Ellipsoidal and orthometric heights](/learn/ellipsoidal-and-orthometric-heights). ### Where to set the coordinate system Set the coordinate system deliberately at each step, and make every step match: * Rover or controller: the field software applies the projection, the geoid model and any site calibration to the corrected position. * Drone or mapping app: check which frame the app writes to the image or point metadata. Some apps label every position WGS84, whatever frame the corrections arrive in. * Office software: set the processing project to the same frame and epoch as the field data and the control points. ### Transformations * Where a national grid file exists, for example OSTN15 in Great Britain or an NTv2 grid in several other countries, use it rather than a seven-parameter transformation. Grid files reach centimetre level; a general seven-parameter transformation can be off by metres for some national systems. * Apply exactly one transformation between the delivered frame and your project system. Applying a second one, for example in both the controller and the office software, doubles the shift. ### Control, cadastral and legal work For control, cadastral and legal surveys, validate results against the national control network and follow the requirements of the responsible national authority. Measure at least one known control point at the start of every job. ### Satellite systems The corrections support GPS, GLONASS, Galileo, and BeiDou where the local network tracks them. ### Correction stream * Format: RTCM 3.x * Mountpoint: COMMON * Update rate: 1 Hz * Position sending: send a GGA message every 5 seconds or so, so the network can build the correction for where you are. See [Mountpoint selection and the GGA heartbeat](/troubleshooting/mountpoint-selection-and-the-gga-heartbeat). Your receiver's position output rate, for example 5 Hz or 10 Hz, is set on the receiver and does not depend on the correction rate. ### FAQ Which datum are RTK Premium corrections in? It depends on the region; see the table above. In Europe, the corrections are delivered in ETRS89 (ETRF2000, epoch 2010.0). In the United States, they are delivered in NAD83(2011), epoch 2010.0, and in Canada in NAD83(CSRS), epoch 2010.0, with ITRF available on request in both. In Hawaii, they are delivered in NAD83(PA11), epoch 2010.0. In Japan, they are delivered in ITRF2008, epoch 2005.0. In Australia, they are delivered in GDA2020, epoch 2020.0. My coordinates are about a metre off from my project control. Why? Most often one side of the comparison is in a global frame such as ITRF or WGS84 and the other in a plate-fixed frame such as NAD83 or ETRS89. Put the field data, the control and the processing project in the same frame and epoch. Can I work in a national grid or local system? Yes. Set up the transformation from the delivered frame to your national or local system in your field software, then check it against a known point. Which satellite systems do the corrections cover? GPS, GLONASS, Galileo, and BeiDou, where the local network tracks them. Can I get corrections at a higher rate? The correction stream runs at 1 Hz. Your receiver's position output rate is set on the receiver and does not depend on the correction rate. If your application needs a higher correction rate, contact support. # Getting started Start a free 14-day RTK Premium trial: what happens after you submit the form, how to connect your receiver, and where to get help. You can try RTK Premium free for 14 days. Fill out the trial form, and your account arrives by email within two working hours, with everything you need to start receiving corrections. The trial gives you full access to the RTK Premium correction network in 35+ countries, at 1 to 2 cm accuracy. It works with any NTRIP-capable receiver, so there is no special hardware to buy first. ### Start your free trial Request your trial on the [free trial form](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=getting-started). You will need a few basic details and the GNSS receiver you plan to test with. ### What happens after you submit the form 1. We create your account. This usually takes up to two working hours. 2. You receive your login credentials by email. If you do not see them, check your junk or spam folder, as the RTK Premium email can land there. 3. You log in to the XYZ Platform. The email includes instructions for signing in and finding your correction details. 4. You connect your receiver. Add the correction stream to your receiver as an NTRIP client, using the steps in [Connect a receiver](/set-up-and-connect/connect-a-receiver). If you are new to NTRIP, [What is NTRIP](/learn/what-is-ntrip) explains how the connection works. 5. You start receiving corrections. Once the receiver reports a fixed solution, you are positioning to 1 to 2 cm. ### Testing during the trial During the trial you can measure RTK Premium against your current service on RTKTEST.com, the open benchmark Premium Positioning runs. [Testing a correction service](/learn/testing-a-correction-service) explains how. ### If you need help during the trial Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338. If your receiver will not connect or the fix is not holding, start with the [troubleshooting guides](/troubleshooting/rtk-corrections-troubleshooting), which cover connection errors, dropped fixes, and inconsistent accuracy. ### Continuing after the trial The trial runs for 14 days. To keep your corrections running after that, [request pricing](https://www.premium-positioning.com/pricing?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=getting-started) for the plan that fits your fleet, or contact the team at . # Connect a receiver Connect any NTRIP-capable receiver to the RTK Premium caster: host, port, mountpoint and credentials, with checks for a fixed solution. To receive RTK Premium corrections, connect your receiver to our NTRIP caster using your account credentials. The steps below are generic and work with any NTRIP-capable receiver. The menu names differ from one brand to the next, but the settings you enter are the same everywhere. If you have not connected over NTRIP before, [What is NTRIP](/learn/what-is-ntrip) explains the caster, mountpoint, and GGA heartbeat in plain terms. ### Before you start * An NTRIP-capable GNSS receiver or controller. * An internet connection for the receiver, whether through its own SIM, a paired phone or controller, or Wi-Fi or Ethernet for a fixed install. * Your RTK Premium credentials, which arrive by email when your trial or subscription is set up. If you do not have them yet, start with the [free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=connect-a-receiver). * A clear view of the sky at the point you are measuring. ### Connection settings Enter these in your receiver's NTRIP or correction-source settings: * Caster address (host or server): rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Username: your account username * Password: your account password Username and password are case sensitive. Use the exact values from your account email rather than the example shown here. ### Steps to connect 1. Open the correction settings. Look for a menu called NTRIP client, internet base, correction source, or data link, depending on your brand. 2. Create a new NTRIP connection and enter the caster address and port from above. 3. Enter your username and password. 4. Load the mountpoint list. Most receivers fetch the caster's list of mountpoints once the address, port, and credentials are in. Select COMMON. If your receiver does not fetch the list, type COMMON in the mountpoint field by hand. 5. Turn on position sending if your receiver asks. This sends your approximate position to the network as a GGA message, the heartbeat the network needs to tailor the correction to where you are. Leave it enabled. 6. Connect. The receiver requests the stream and starts receiving corrections. You should see the correction age begin to count in seconds. 7. Wait for a fixed solution. The receiver moves from an autonomous position to float, then to fixed. Once it reports RTK Fixed, you are positioning to 1 to 2 cm. ### Check it is working * The solution status reads fixed, not float or autonomous. * The correction age stays low, within a few seconds. * If a known point is nearby, measure it and confirm the result matches its published coordinates. ### Choosing a different mountpoint COMMON suits most receivers. Depending on your subscription and region, other mountpoints may be available, for example streams carrying different constellations or message sets. See [Mountpoint selection and the GGA heartbeat](/troubleshooting/mountpoint-selection-and-the-gga-heartbeat) for how to choose. ### If it will not connect * No mountpoint list appears: re-check the address, the port, and your internet connection. * Authentication failed: re-enter the username and password exactly, mind the capitals, and confirm your subscription is active. * Connected but no fix: make sure position sending (GGA) is on, move to open sky, and give the receiver time to resolve the ambiguities. For more, see the [troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) guide. If it still will not connect, contact support at or +31 85 0606 338 with your receiver model, the mountpoint, the solution status, and the correction age. # All devices A to Z Every receiver, app, drone and system with an RTK Premium setup guide, in alphabetical order.

These steps connect a Carlson BRx7 / BRx6+ / BRx6 / Surveyor+ to the Premium Positioning correction network over NTRIP, using Carlson SurvPC / SurvCE. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=carlson-brx7-brx6%2B-brx6-surveyor%2B) to get your credentials. * Carlson SurvPC / SurvCE. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=carlson-brx7-brx6%2B-brx6-surveyor%2B#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get an internet connection: NTRIP corrections arrive over the internet, so the data collector needs to be online - a SIM in the collector/receiver, or a Wi-Fi hotspot from a phone/MiFi. Power on the BRx7/BRx6+ with clear sky and pair it to your controller over Bluetooth first. 2. Open GPS Rover: From the SurvPC/SurvCE main menu tap Equip > GPS Rover. Carlson Layout uses the same flow. 3. Set the receiver and connect: On the Comms / Current tab set Manufacturer to Carlson and Model to your unit (BRx7 or BRx6+), then connect over Bluetooth. Wait until it reports connected. 4. Go to the RTK tab: Tap the RTK tab - this is where you tell SurvPC where the correction stream comes from. 5. Set the Device (internet source): In Device pick where the internet lives: 'Data Collector GSM or WiFi' if the tablet is online (SIM or hotspot), or 'Receiver GSM' / Internal GSM if the SIM is in the BRx7. For a receiver SIM, tap the gears icon to set your provider's APN and confirm. 6. Set Network to NTRIP: In Network choose NTRIP, then tap the gears/wrenches icon next to Network to open the NTRIP Broadcasters window. 7. Add the Premium Positioning caster: Tap New (or add/edit) to create a caster named e.g. 'Premium Positioning'. Enter IP addr / Server: rtkpremium.xyz, Port: 2101. 8. Enter YOUR NTRIP credentials: Enter the User name and Password from your Premium Positioning welcome email - unique to your account; do not use anyone else's. 9. Download the mountpoint list: Tap the green check. SurvPC connects to rtkpremium.xyz and downloads the broadcast table (mountpoints) into the Name drop-down. 10. Select the COMMON mountpoint: In the Name / base-station drop-down choose COMMON. (Some networks offer a NEAR/NRST auto-nearest entry, but for Premium Positioning select COMMON.) Tap the green check. 11. Confirm the configuration: Back on the RTK tab, check it shows the Premium Positioning caster with the COMMON mountpoint, then tap the green check to apply. 12. Confirm a FIXED solution: Go to Equip > Monitor/Skyplot > Quality tab. Status should change to FIXED within a minute or two (cm accuracy). If it stays Float/Autonomous, re-check credentials, that the controller is online, and Server/Port/Mountpoint. Take a checkshot on a known point before surveying. ### If the fix will not hold Wording varies by SurvPC/SurvCE version (e.g. Device may read 'Data Collector Internet'; the gears icon may appear as wrenches), and Carlson Layout follows the same flow. Tip: once FIXED, Save these as a configuration profile from the GPS Rover - Current tab to reload next time. If your exact model isn't listed, choose the closest Carlson BRx6 entry - the correction workflow is the same.

These steps connect a CHCNAV i89 / i89 Pro to the Premium Positioning correction network over NTRIP, using LandStar 7. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=chcnav-i89-i89-pro) to get your credentials. * LandStar 7. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=chcnav-i89-i89-pro#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and pair over Bluetooth: Turn on the i89 / i89 Pro and your controller, enable Bluetooth, and open LandStar 7. Make sure the receiver is fully booted before connecting. 2. Open Config > Connect: From the main menu tap Config, then Connect - where LandStar 7 links the software to your receiver. 3. Set the connection details: Set Manufacturer to CHC and choose the matching Device Type (e.g. GNSS RTK). Set Connection Type to Bluetooth. 4. Find and pair the receiver: Tap the Bluetooth list / Refresh to scan, select your i89 by serial number, and pair (if a PIN is requested, the CHC default is usually 1234). When it shows connected, you return to the Connect screen. 5. Open Config > Work Mode and create a new rover mode: Tap Config > Work Mode > New to create a fresh work mode - where rover correction settings live. 6. Set it to an internet rover: Switch RTK on. Set Work Mode to Auto Rover. Set Datalink to Receiver Network (routes corrections over the receiver's built-in SIM/internet). On some versions this is labelled Phone Internet or Receiver Internet, and the SIM data link may be called GSM/GPRS - pick the receiver-network/internet option for your version. 7. Choose the NTRIP protocol: Set Protocol to NTRIP. On some LandStar 7 builds the equivalent is labelled CORS - if you don't see NTRIP, select CORS; they refer to the same standard NTRIP workflow. 8. Enter the Premium Positioning caster address: In the server / IP and Port fields enter Host: rtkpremium.xyz and Port: 2101 - fixed and identical for every customer. (If a SIM APN prompt appears, set it for your mobile carrier.) 9. Enter your own NTRIP login: Type the NTRIP User name and Password from your welcome email - personal to your account, exactly as supplied; do not share them. 10. Download the source table: Tap Download (or Get source table) to pull the available mount points from the caster. This confirms the host, port, username and password are correct. 11. Select the COMMON mount point: From the downloaded source table / access point list, select COMMON - the correct mount point for all Premium Positioning customers. 12. Save, name, and accept the work mode: Tap Save. At 'Please Set a Name for The New Mode' enter a name (e.g. PP NTRIP) and OK, then OK at 'Create Mode Successfully'. Select your new work mode and tap Accept. Review the CORS/NTRIP info (host, port, COMMON) and tap OK. 13. Confirm a Fixed solution: Watch the solution status move Single → Float → Fixed (the receiver LED also changes once it locks). Once it reads Fixed you're receiving corrections and ready to survey. If it stays Single/Float, recheck the credentials, the COMMON mount point, and that you have mobile data/sky view. ### If the fix will not hold Menu labels vary slightly between LandStar 7 versions/firmware (Receiver Network vs Phone Internet vs Receiver Internet; NTRIP vs CORS; Download vs Get source table) - pick the closest matching option. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # CHCNAV i93 / i90 / i83 / i73 Connect a CHCNAV i93, i90, i83 or i73 to RTK Premium corrections over NTRIP using LandStar 7: caster settings and the steps to a fixed solution. These steps connect a CHCNAV i93 / i90 / i83 / i73 to the Premium Positioning correction network over NTRIP, using LandStar 7. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=chcnav-i93-i90-i73) to get your credentials. * LandStar 7. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=chcnav-i93-i90-i73#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and connect the receiver: Switch on the CHCNAV receiver (i93 / i90 / i73) and the controller running LandStar 7. In LandStar 7 open Config and tap Connect. Set Manufacture to CHC, choose your receiver model, set Connection Type to Bluetooth, tap Search, select your receiver's serial number, then Connect. Wait for it to show linked and tracking satellites. 2. Open Work Mode: From the Config menu tap Work Mode. This lists saved Base/Rover profiles. You'll create or edit a Rover mode that uses an internet (NTRIP) data link. 3. Add a new Rover work mode: Tap Add (or New), set the Operating Mode to Rover (not Base or Static), and give it a name such as 'Premium Positioning NTRIP'. 4. Choose the Data Link: Set Data Link to your internet path: 'Receiver Network' if a SIM is in the receiver, or 'Phone Internet' / 'PDA Network' if the data connection comes from the controller/phone. Pick whichever device holds your internet connection. 5. Set the protocol to NTRIP: Set the Protocol (server type) to NTRIP. This exposes the NTRIP fields: server IP/host, port, mount point, username and password. (CORS/APIS are the other options - you don't need them.) 6. Create the Premium Positioning server entry: Open the server/CORS list, tap Add / '+', enter a name like 'Premium Positioning', then Server / IP / Host: rtkpremium.xyz and Port: 2101, and save. The exact 'add server' control varies by LandStar 7 version. 7. Select the server: Back on the Rover work mode, make sure the new 'Premium Positioning' server (rtkpremium.xyz : 2101) is the selected/active entry. 8. Enter YOUR NTRIP credentials: In Username and Password type the personal NTRIP login from your Premium Positioning welcome email (case-sensitive, unique to your account). 9. Retrieve the source table (mount point list): Tap the refresh icon next to the Mount Point field (some versions label it 'Get source table' or 'Get access point'). LandStar 7 connects and downloads the list. If it stays empty, re-check host, port, credentials, and that the device has internet. 10. Select the COMMON mount point: From the Mount Point list, select COMMON - the Premium Positioning correction stream your rover will use. 11. Apply the work mode: Tap OK / Apply / Save, then start/activate it so LandStar 7 requests corrections from rtkpremium.xyz:2101 on COMMON. The status bar should show data being received (the age-of-corrections indicator updates). 12. Confirm a Fixed solution: Watch the top status bar progress Single → Float → Fixed, typically within seconds to a minute or two with good sky view. Once Fixed with a low age-of-corrections, the rover is ready for cm-accurate work. ### If the fix will not hold If no mount points appear when you refresh, the usual causes are a typo in the host (rtkpremium.xyz) or port (2101), wrong credentials, or no internet on the device carrying the data link. If you reach Float but never Fixed, move to clearer sky away from buildings and trees. Button/field names differ slightly between LandStar 7 versions (e.g. 'Phone Internet' vs 'PDA Network', a refresh icon vs a 'Get source table' button); the Config → Work Mode → Rover → Data Link → NTRIP → server → credentials → mount point → apply sequence is the same. Menu/button labels differ slightly between LandStar 7 versions (and LandStar 8): the protocol may read NTRIP or CORS, the source-table button Download/Get/Source, and the controller-internet data link Phone Internet/Controller Internet/PDA Network. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # ComNav N5 / T30 Connect a ComNav N5 or T30 to RTK Premium corrections over NTRIP using Compass or SurvStar: caster settings and the steps to a fixed solution. These steps connect a ComNav N5 / T30 to the Premium Positioning correction network over NTRIP, using Compass / SurvStar (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=comnav-n5-t30) to get your credentials. * Compass / SurvStar (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=comnav-n5-t30#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and charge before you start: Switch on the N5 / T30 and give it a clear view of the sky (outdoors, away from buildings/trees). Power up your Android controller/phone and confirm it has working mobile-data or Wi-Fi - corrections come over the internet. 2. Open the field software and create/open a job: Launch Compass or SurvStar. Open or create a project ('Project'/'Job' menu) so survey data has somewhere to go. Wording varies by app version - look for the equivalent option. 3. Connect to the receiver over Bluetooth: Go to the connection screen ('Device' > 'Connect', or 'Config' > 'Communication'). Choose Bluetooth, search/scan, and select your receiver by its serial number. Pair if prompted - ComNav units commonly use PIN 0000 (some 1234). Wait for connected status. 4. Set the receiver to Rover mode: Open the working-mode screen ('Device' > 'Rover' / 'Work Mode', or 'Config' > 'Work Mode') and select Rover (also 'Auto Rover' on some menus) so it receives corrections. 5. Set the datalink to network / internet: In Rover settings, set 'Datalink' to the internet option - 'Internet', 'Network', 'GPRS', 'PDA Network' or 'Phone Internet' depending on whether the controller or the receiver's SIM provides the connection. Choose the controller/phone internet option unless you have a SIM in the receiver. Not Radio. 6. Choose NTRIP as the protocol: With the datalink set to network, select Protocol NTRIP ('Ntrip' / 'NTRIP Client'). Not APIS, TCP/IP direct, or other protocols. 7. Enter the caster address and port: In the NTRIP / CORS settings: Host / Server / IP: rtkpremium.xyz, Port: 2101 (same for every customer). If the field is 'IP' and only accepts a numeric address, use the 'domain'/'address' field, or contact support for the resolved IP. Protocol stays NTRIP. 8. Enter YOUR NTRIP username and password: Type the NTRIP username/password issued to YOU in your welcome email - unique to your account; do not use anyone else's. The connection fails without your own valid credentials. 9. Retrieve the source table (mountpoint list): Tap the button that fetches the streams - 'Get', 'Get Source Table', 'Get Mountpoint', or a refresh icon next to the mountpoint field. If nothing appears, re-check host, port, internet, and credentials. 10. Select the COMMON mountpoint: From the source table, select COMMON - the fixed mountpoint for all customers. Scroll/search if the list is long. Confirm/OK. 11. Connect to the caster: Tap Connect ('Apply' then 'Connect', or 'OK'). The app logs in to rtkpremium.xyz with your credentials and streams RTCM. A connection/active indicator or data-flow counter starts. 12. Confirm a Fixed solution: Watch the solution status (main survey screen or status bar): Single → Float → Fixed within \~10 - 60 s under open sky. Only at Fixed are coordinates at full cm accuracy. If it stays Float/Single, check that COMMON is selected, you have open sky, and your credentials/internet are correct. 13. Start surveying: Once Fixed, go to your measure/stakeout screen and collect points. If the connection drops, re-open the NTRIP/datalink screen and tap Connect again; the saved settings should still be in place. ### If the fix will not hold Compass and SurvStar are both Android apps for ComNav/SinoGNSS receivers and share the same flow, but exact menu/button names differ between apps and versions - treat 'Datalink', 'Get Source Table', 'Work Mode' as the nearest equivalent if your screen differs. The receiver needs clear sky and the controller needs working internet. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a ComNav T300 / N3 to the Premium Positioning correction network over NTRIP, using Compass / SurvStar (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=comnav-t300-n3) to get your credentials. * Compass / SurvStar (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=comnav-t300-n3#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and pair the receiver: Turn on the ComNav T300/N3 and enable Bluetooth on your Android controller. Ensure clear sky and the receiver fixed on the pole. 2. Open the field software: Launch Compass or SurvStar and open/create your job. NTRIP settings live under the Device (or Communication) and Survey/Config menus. 3. Connect over Bluetooth: Go to Device > Communication (or Connect). Set Device type to ComNav, mode to Bluetooth, scan, select your T300/N3 by serial number, and Connect. Wording varies slightly by app version. 4. Set work mode to Rover: Open the Rover / Work Mode setup (sometimes 'RTK work mode' with a 'Change work mode' button) and select Rover (in some firmware 'Auto Rover'). 5. Set the Datalink to network/internet: Set Datalink to use the internet - the controller's internet (phone/network datalink) or the receiver's internal network/SIM. In ComNav terms this is shown as 'Rover Ntrip/IP'. 6. Choose NTRIP protocol: Set the protocol/connection type to NTRIP (not TCP/IP direct or radio). If asked for a version, NTRIP 1.0 is a safe default. 7. Open the NTRIP / Datalink configuration: Add or edit an NTRIP profile (e.g. tap ADD in the Datalink Config screen) to enter the caster address, port, credentials, and mountpoint. 8. Enter the Premium Positioning caster: Server/Host (IP or domain): rtkpremium.xyz - Port: 2101 - Protocol: NTRIP. If a Mountpoint field shows now you can set COMMON, but it's easier to pick it from the source table next. 9. Enter YOUR NTRIP username and password: Type the username/password from your Premium Positioning welcome email - unique to your account, case-sensitive; do not use anyone else's. 10. Retrieve the source table: Tap Get / Get List / Source List (sometimes 'Download Source Table') to pull the mountpoints. A successful retrieval confirms address, port and credentials are correct. 11. Select the COMMON mountpoint: From the source list select COMMON, confirm/OK. The receiver begins requesting RTK corrections. 12. Connect and start receiving corrections: Confirm/Apply the datalink. The app shows the link connected and RTCM data arriving; the data age/latency counts low single-digit seconds. 13. Confirm a Fixed solution: Watch the status progress Single/Autonomous → Float → Fixed. Begin measuring only once it reads Fixed with low data age and cm-level precision. ### If the fix will not hold Names differ between Compass and SurvStar and across versions - match by purpose (connect, Rover, datalink/NTRIP, source list, mountpoint, Fixed). If you can't reach Fixed: verify internet, re-check credentials (case-sensitive), confirm the source table loads, select COMMON, and ensure clear sky within coverage.

If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=emlid-reach-rs2-rs3-rs2%2B#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on the receiver with clear sky: Hold the power button until the LED lights up. Place the Reach outdoors with a clear, unobstructed view of the sky (Emlid recommends at least 30° above the horizon in all directions) - sky view is the biggest factor in a fast, reliable FIX. 2. Install and open Emlid Flow: Install Emlid Flow (formerly ReachView 3) from the App Store or Google Play and open it. Make sure your phone/tablet has working internet (mobile data or Wi-Fi) - in the common setup the receiver borrows your phone's internet for corrections. 3. Connect the app to your receiver: Connect to your Reach - simplest is Bluetooth: enable Bluetooth, then select your receiver from the device list (the name includes the model and serial, e.g. 'Reach RS3'). You can also join the receiver's own Wi-Fi hotspot. Connection wording varies slightly by app version/platform. 4. Decide how the receiver gets internet: If you connected over Bluetooth, Emlid Flow automatically shares your phone's internet with the receiver - no extra setup. To use the receiver's own connection instead, join it to Wi-Fi or use a SIM (RS3). For most users, Bluetooth + phone internet is the recommended path. 5. Set GNSS settings (recommended): Go to Settings > GNSS settings and confirm: Positioning mode Kinematic, Elevation mask 15°, SNR mask 35°, all satellite systems enabled, update rate 5 Hz. Tap Apply. 6. Open the Correction input screen: Go to Settings and open Correction input - this is where you tell the receiver where to fetch RTK corrections. 7. Choose the NTRIP correction source: Select NTRIP. If connected over Bluetooth you'll be offered an internet source - choose 'Internet over mobile's device' so the receiver uses your phone's connection. (If the receiver has its own Wi-Fi/cellular, choose the option that uses the receiver's internet - wording varies by version.) 8. Add a new NTRIP profile: Tap Add profile to create a new connection to Premium Positioning's caster. You'll see fields for the address, port, mount point, and your login. 9. Enter the caster address and port: Address: rtkpremium.xyz Port: 2101. These are the same for every Premium Positioning customer. 10. Enter YOUR NTRIP username and password: In Username and Password enter the personal credentials from your Premium Positioning welcome email - unique to your account; don't guess. If you can't find them, contact Premium Positioning support to have them resent. 11. Select the mount point: Set the mount point to COMMON. Depending on your app version you can type COMMON directly, or tap the field to fetch the caster's source table and pick COMMON from the list. If no list loads, enter COMMON manually. 12. Save the NTRIP profile: Tap Save. Emlid Flow connects to rtkpremium.xyz and begins streaming corrections. An authentication error means re-check username/password; a mount point error means re-check it is COMMON. 13. Confirm the corrections link is active: On the Correction input / status screen, confirm the profile shows connected and correction data is being received. If not within a few seconds, check the phone has internet and the receiver has clear sky. 14. Watch the solution status reach FIX: Check the status indicator at the top: it progresses SINGLE → FLOAT → FIX. FIX means cm-level accuracy and you're ready to survey - usually a few seconds up to a minute or two with good sky view. ### If the fix will not hold Work outdoors with a clear sky view (30°+ above the horizon) and keep the phone's internet active, since over Bluetooth the receiver relies on your phone for data. Screen/button wording differs slightly between Emlid Flow versions and between iOS and Android. If you can't get past FLOAT to FIX, the usual causes are poor sky view, weak phone signal, or the wrong mount point.

These steps connect an eSurvey E300 Pro / E600 to the Premium Positioning correction network over NTRIP, using SurvStar / eSurvey field app (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=esurvey-e300-pro-e600) to get your credentials. * SurvStar / eSurvey field app (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=esurvey-e300-pro-e600#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and pair: Switch on the E300 Pro / E600 and your Android controller. Turn on Bluetooth so the receiver can be discovered. Ensure a charged battery and clear sky. 2. Open the field app: Open SurvStar (the eSurvey field app, part of the SurvX / SurPad family). Open/create a project if prompted. The icon may read SurvStar or eSurvey Field - same software. 3. Connect to the receiver: Go to the Device menu (Device or Connect / Communication by version) and choose Connect. Set Manufacturer to eSurvey, connection type Bluetooth, search and select your receiver's serial number, then Connect. Wait for 'Connected'. 4. Set the receiver to Rover: In Device open Rover (Device > Rover or Receiver > Rover) so the receiver applies incoming corrections. Configure the data link from this screen. 5. Choose the data link: Set Data Link to the internet option: Phone Network / PDA Network (Android device's data or Wi-Fi) or Receiver Network (SIM in the receiver). Phone/PDA Network is simplest. Wording varies by SurvStar version. 6. Select NTRIP protocol: Set the Protocol (Server type / CORS) to NTRIP, so the app logs in to a caster and pulls a correction stream. 7. Enter the caster address and port: IP / Server = rtkpremium.xyz and Port = 2101. If there's a saved-server list, tap Add to create a profile, enter these, save and select it. 8. Enter YOUR NTRIP credentials: In User Name and Password enter the NTRIP credentials from YOUR welcome email - unique to your account; do not use example values. Save the profile if prompted. 9. Get the source table: Tap Get Access Point (or Get Source Table / refresh icon next to Mount Point). The app connects and downloads the mount points; wait a few seconds. 10. Select the COMMON mount point: Open the Mount Point list and select COMMON (type it manually if it doesn't appear after refreshing). 11. Start the connection: Tap Start / OK / Connect to stream corrections. If login fails, re-check the username/password (case-sensitive) and that the data link has internet. 12. Confirm a Fixed solution: Watch the status move Single → Float → Fixed (RTK Fixed). Once Fixed the rover is cm-accurate. Stand still with clear sky if it stalls on Float. ### If the fix will not hold The eSurvey field app is part of the SurvX / SurPad software family, so menu wording can differ slightly between versions - match the closest equivalent. Reaching Fixed needs clear sky and a working internet connection. If you can't get the source table, the usual causes are wrong username/password or no mobile data. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # FOIF A60 / SmaRTK Connect a FOIF A60 or SmaRTK to RTK Premium corrections over NTRIP using the FOIF field app: caster settings and the steps to a fixed solution. These steps connect a FOIF A60 / SmaRTK to the Premium Positioning correction network over NTRIP, using FOIF field app (Forsurvey / SurvX-style). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=foif-a60-smartk) to get your credentials. * FOIF field app (Forsurvey / SurvX-style). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=foif-a60-smartk#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Before you start: Have your Premium Positioning NTRIP credentials ready - the username and password from your welcome email (each customer has their own; PP never shares one set). Make sure the FOIF A60 is on and your phone/tablet has working mobile data (corrections come over the internet). 2. Open the FOIF field app: Launch the FOIF survey app on your Android device (Forsurvey, or whichever SurvX/SurPad-style app shipped with your A60). Open or create a job if prompted. FOIF's app is built on the eSurvey SurvX/SurPad platform, so the wording below follows that workflow - labels should match closely but may differ slightly by version. 3. Connect to the receiver (Bluetooth): Tap Device > Communication. Set the manufacturer and device type to your A60/SmaRTK, set Communication mode to Bluetooth, then tap Search. When your receiver's serial appears, tap Stop, select it, and tap Connect (tap Pair if asked on first connection). 4. Open Rover settings: Once connected, tap Device > Rover to open the Rover mode settings - where you tell the receiver to listen for corrections and how to receive them. 5. Set the Data Link to Phone Internet: In the Rover screen, tap Data Link and choose Phone Internet - sends NTRIP corrections over your phone/tablet's mobile data, so you don't need a SIM in the receiver. 6. Choose NTRIP as the protocol: If a Connect Mode / protocol option is shown, set it to NTRIP (the standard mode used by CORS networks). Leave GGA upload interval at its default (typically 5 seconds). 7. Enter the caster server and port: In CORS Settings, add/edit the server: Server (IP/host) rtkpremium.xyz, Port 2101. If the app keeps a saved list of casters, create an entry named e.g. 'Premium Positioning' so you can reuse it. 8. Enter your NTRIP username and password: Still in CORS Settings, type the User and Password from your welcome email. Use YOUR own credentials exactly as supplied (case-sensitive) - do not guess or reuse anyone else's. 9. Get the access point (source table): In MountPoint Settings, tap Get Access Point (Get Mount Point on some versions). The app connects and downloads the list of mount points. If nothing loads, recheck host, port, credentials, and your internet connection. 10. Select the COMMON mount point: From the downloaded list, select COMMON - the correct mount point for all Premium Positioning customers on rtkpremium.xyz. 11. Apply the settings: Tap Apply (or OK/Confirm) to save the Rover configuration. The receiver requests corrections and feeds them into its position solution. 12. Confirm a Fixed solution: Return to the survey screen and watch the status bar: Single → Float → Fixed, usually within 10 - 30 seconds. Fixed (RTK) means cm-level accuracy and you're ready to survey. If it stays Single/Float, confirm mobile data is working, that you selected COMMON, and that your credentials are correct. ### If the fix will not hold The menu/button names follow the eSurvey SurvX/SurPad 4.2 workflow that FOIF's Forsurvey app is based on; your version's labels (e.g. Get Access Point vs Get Mount Point, Apply vs OK) may differ slightly but the sequence is the same. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # FOIF A90 / A30 Connect a FOIF A90 or A30 to RTK Premium corrections over NTRIP using the FOIF field app: caster settings and the steps to a fixed solution. These steps connect a FOIF A90 / A30 to the Premium Positioning correction network over NTRIP, using FOIF field app (Forsurvey / SurvX-style). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=foif-a90-a30) to get your credentials. * FOIF field app (Forsurvey / SurvX-style). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=foif-a90-a30#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and get online: Switch on the FOIF A90/A30 outdoors with clear sky. On the controller, turn on Bluetooth and ensure a working internet connection (mobile data or Wi-Fi). 2. Open the FOIF field app: Launch the FOIF field app (Forsurvey). It uses the standard SurvX/SurPad-style layout, so the menu names below match that family; your build's wording may differ slightly but the flow is identical. 3. Connect to the receiver (Device > Communication): Go to Device > Communication. Set Manufacturer to FOIF and device type to your model, choose Bluetooth, press Search. When your receiver's serial appears, press Stop, select it, and Connect (Pair if prompted). 4. Switch to Rover mode (Device > Rover): Go to Device > Rover to open the rover settings - this tells the A90/A30 to receive corrections rather than transmit. 5. Open the Data Link and choose internet: On the Rover screen press Data Link. Choose Phone Internet (controller's connection) or Device Internet (SIM in the receiver). Phone Internet is simplest if the phone is online. 6. Set the connection protocol to NTRIP: Set Connect Mode / Protocol to NTRIP (the standard CORS network protocol). Avoid CSD, TCP or Custom. 7. Enter the caster address and port: In CORS Settings enter Server/IP: rtkpremium.xyz and Port: 2101. Use the host-name field for rtkpremium.xyz; press the + next to CORS Settings to add it as a new server if needed. 8. Enter YOUR NTRIP username and password: In CORS Settings type the NTRIP User and Password from your Premium Positioning welcome email - unique to you. If you haven't received credentials, contact support first. 9. Retrieve the source table: In MountPoint Settings press Get Access Point (also 'Get Mount Point'). The app downloads the available mountpoints. 10. Select the COMMON mountpoint: From the list select COMMON - the Premium Positioning correction stream for your network. 11. Apply and connect: Press OK / Apply, then confirm to start the NTRIP connection. The app logs in and streams corrections to the receiver. 12. Confirm a Fixed solution: On the survey screen watch Single > Float > Fixed (within \~15 - 60 s). Once Fixed with cm precision you're ready. If it stays Single/Float, re-check credentials, mountpoint, and internet. ### If the fix will not hold FOIF A90/A30 run a SurvX/SurPad-style app (Forsurvey), so the menu names above match that family; your build's exact wording may vary slightly but the workflow is the same. A clear sky view and a stable internet connection are required to reach and hold a Fixed solution. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a GeoMax Zenith16 / Zenith35 Pro to the Premium Positioning correction network over NTRIP, using X-PAD Ultimate (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geomax-zenith16-zenith35-pro) to get your credentials. * X-PAD Ultimate (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geomax-zenith16-zenith35-pro#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and prepare: Switch on the Zenith16/Zenith35 Pro and the Android device running X-PAD Ultimate. Ensure clear sky and that the controller has working internet (SIM data or Wi-Fi hotspot) - corrections are pulled over the controller's connection. 2. Open the instrument profile list: In X-PAD Ultimate go to Settings and tap 'GNSS & Total stations' to show your instrument profiles. Tap 'Add' for a new profile (older builds: the 'New' button in Instruments setup). 3. Define the profile as a GNSS Rover: Choose 'GNSS Receiver (GNSS)', then enter a Profile name (e.g. 'Premium Positioning NTRIP'), set Mode to 'GNSS Rover', Brand to 'GeoMax' and Model to your Zenith unit. Tap Next. 4. Pair the receiver over Bluetooth: Set the connection to Bluetooth, tap 'Add device' / 'Find devices', search, and select the entry matching your receiver's serial number (on Zenith16 you can scan its QR code). Confirm pairing and tap Next. Button wording ('Add device' vs 'Search Device') varies by version. 5. Choose internet corrections on the RTK page: Set the correction Device to internet/GPRS. On a phone/tablet choose 'External GPRS (controller)' so corrections come through the controller's data; choose 'Internal GPRS' only if using the receiver's own SIM. Tap Next to the RTK GPRS page. 6. Create the NTRIP server entry: Tap the Server field and choose 'NTRIP servers' to add a service. Create a server: Name 'Premium Positioning'; IP Address / Server: rtkpremium.xyz; Port: 2101; Protocol: NTRIP. Save it. 7. Enter YOUR NTRIP username and password: Fill UserID and Password with the personal NTRIP credentials from your Premium Positioning welcome email - unique to your account. The host/port are shared by all customers; the login is per-user. 8. Retrieve the source table and select the mountpoint: Tap the 'Mountpoint' field. X-PAD connects and downloads the source table. Select COMMON. If the list doesn't appear, re-check host, port and credentials, then tap Mountpoint again to refresh. 9. Set the correction data format: Set 'Data format' to match the COMMON stream (typically RTCM 3.x). If unsure, leave the default/auto RTCM 3 setting - the COMMON mountpoint streams standard RTCM 3 corrections. 10. Set the GNSS parameters and antenna: Accept sensible defaults (cut-off \~10 - 15°, GLONASS/Galileo on, up to 5 Hz for stakeout). On the Antenna page confirm the correct Zenith antenna and your measured antenna height. Tap End to save. 11. Connect and start corrections: Select the new profile to make it current - X-PAD connects to the Zenith over Bluetooth and logs in to the caster. If corrections don't start, open the GPS status window, tap Setup and choose 'Connect GPRS' to restart the NTRIP session. 12. Confirm a Fixed solution: Open the GPS status window and check Quality > Position. Wait for 'RTK Fixed' (cm precision). 'RTK Mobile'/Float means corrections arrive but aren't fixed; 'Autonomous'/'DGPS' means no RTK. The page also shows the NTRIP Server, Mountpoint (COMMON) and Age of corrections - keep age low (a few seconds). ### If the fix will not hold The controller needs live internet (SIM data or hotspot). Labels differ between X-PAD Ultimate versions (e.g. 'GNSS & Total stations' / 'Add' vs older 'Instruments setup' / 'New'; 'Find devices' vs 'Search Device'); the sequence - pick Rover, choose internet/GPRS, create the NTRIP server, download the source table, pick COMMON - is the same. A persistent Float usually means poor sky view, weak data signal, or a mismatched correction format. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # GeoMax Zenith40 / Zenith05 Connect a GeoMax Zenith40 or Zenith05 to RTK Premium corrections over NTRIP using X-PAD Ultimate: caster settings and the steps to a fixed solution. These steps connect a GeoMax Zenith40 / Zenith05 to the Premium Positioning correction network over NTRIP, using X-PAD Ultimate (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geomax-zenith40-zenith05) to get your credentials. * X-PAD Ultimate (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geomax-zenith40-zenith05#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on the receiver and the Android controller: Switch on your GeoMax Zenith40 / Zenith05 and mount it on the pole. Power on your Android controller (data collector or phone/tablet) and make sure it has working mobile data or Wi-Fi, because corrections are delivered over the internet. Open X-PAD Ultimate. 2. Open or create a job, then go to instrument settings: Open or create a job. From the main menu open Settings, then the section that manages instruments - typically 'GNSS & Total stations' (some versions 'Devices' or 'Instruments'). This is where rover profiles are created and selected. 3. Add a new GNSS Rover profile: Choose Add (the + or 'New' button), then select the GNSS Rover profile type. Pick GeoMax as the brand and your model (Zenith40 or Zenith05). Give the profile a recognisable name. Button wording varies slightly by version - choose the option that creates a new GNSS rover instrument. 4. Connect to the receiver over Bluetooth: On the connection page choose Bluetooth and tap to search. Select your Zenith40 / Zenith05 (its serial usually appears in the name) and confirm to pair/connect. Wait until X-PAD reports it connected. If it doesn't appear, confirm Bluetooth is on and the receiver is powered. 5. Open the RTK / corrections page and set the data link to internet: After the receiver connects, open the RTK (corrections / data link) page. For the correction source choose to receive over the internet using the controller's connection - commonly 'Internet', 'GPRS', or 'Internet of the controller' / 'External GPRS controller'. This routes the NTRIP stream through your Android device's data rather than a modem or radio. Wording varies by version. 6. Choose NTRIP as the protocol: With the internet data link selected, set the correction protocol to NTRIP (not a direct IP/TCP or radio link), so X-PAD connects to an NTRIP caster and requests a mountpoint. 7. Add the NTRIP server (host and port): Open the list of NTRIP servers and choose Add / New. Enter the caster - Host / Server: rtkpremium.xyz, Port: 2101 - the same for every customer. Save the server entry. 8. Enter YOUR NTRIP username and password: In the same NTRIP server form enter the UserID (username) and Password - personal to your account, from your welcome email. Do not share them; if you don't have them, contact support before continuing. 9. Download the source table (mountpoint list): Use the button that retrieves the streams from the caster - usually 'Connect', 'Get source table', or the list/refresh icon next to the mountpoint field. X-PAD downloads the source table. If nothing loads, re-check host, port, credentials, and that the controller has internet. 10. Select the COMMON mountpoint: From the source table, select COMMON - the correction stream all Premium Positioning customers use. Confirm so the entry stores Host rtkpremium.xyz, Port 2101, Mountpoint COMMON, Protocol NTRIP, plus your UserID/Password. 11. Apply and start the rover: Confirm/accept the RTK configuration to apply it and start the rover. X-PAD connects to the caster and feeds corrections to the Zenith. The first connection can take a moment. 12. Confirm RTK Fixed before surveying: Open the GPS Status (satellite/position status) page or check the solution indicator on the survey screen. Wait until it shows 'Fixed' (RTK Fixed) - not Float/DGPS/Autonomous - meaning cm-level accuracy. Only measure once you see RTK Fixed. If it stays Float, recheck the username/password, that COMMON is selected, sky view, and your data connection. ### If the fix will not hold The controller must have a live mobile-data or Wi-Fi connection. Menu/button labels ('GNSS & Total stations', 'Internet of the controller' / 'External GPRS', 'Get source table') can differ slightly between X-PAD Ultimate versions - choose the closest match.

Before you start: GINTEC G10 / KQ Geo K1 receivers run a SurvX-family Android app (SurvX / SurPad / SurX, by Shanghai eSurvey). The screen names below follow the standard SurvX 4.x workflow; exact wording may differ slightly on your version, but the menu structure (Device > Communication, Device > Rover, Data Link, CORS Settings, MountPoint Settings) is the same. You'll need your own NTRIP username and password from your welcome email - do not use anyone else's. 2. Power on and get online: Turn on the receiver and your Android controller/phone. The data collector must have working mobile data or Wi-Fi, because the corrections come over the internet. If using the phone's connection (recommended), make sure mobile data is on. 3. Open the app and connect by Bluetooth: Open the SurvX-family app and go to Device > Communication. Set Device type to your receiver and Connection mode to Bluetooth. Press Search, wait for your receiver's serial to appear, press Stop, select it, then press Connect. On first use, press Pair. The indicator turns green when connected. 4. Open Rover settings: Go to Device > Rover (Rover mode settings) - where you set the receiver as a rover and where corrections come from. 5. Set the Data Link to use the internet: In the Rover screen, open Data Link and choose the internet option. 'Phone Internet' uses your controller/phone's data (simplest, recommended); 'Device Internet' uses a SIM inside the receiver if fitted. These steps assume Phone Internet. 6. Choose the NTRIP protocol: Set Connect Mode (protocol/server type) to NTRIP - the standard mode for CORS-style network corrections. If your version shows it under a CORS/server type list, pick NTRIP there. 7. Enter the caster server address and port: In CORS Settings, add/edit the server: address (IP/Domain) rtkpremium.xyz, Port 2101. Use the '+' or edit button beside CORS Settings to create a new server entry if needed. 8. Enter YOUR NTRIP username and password: Still in CORS Settings, enter the User name and Password exactly as in your welcome email - unique to you. Do not share or guess; if you don't have them, contact support. 9. Fetch the source table: In MountPoint Settings, press Get Access Point (Get Mount Point if you chose Device Internet). The app connects with your credentials and downloads the list of mount points. If nothing loads, recheck the server address, port, credentials, and internet. 10. Select the COMMON mount point: From the downloaded list, select COMMON - the mount point Premium Positioning uses for all customers. If COMMON doesn't appear, your login may not be active yet - contact support. 11. Apply and connect: Confirm/apply the Data Link settings (OK / Apply / Connect). The app sends your position (GGA) to the caster and begins receiving corrections. 12. Confirm a Fixed solution: Return to the survey screen and check the status bar: Single → Float → Fixed as corrections take effect (typically seconds to a minute or two with clear sky and good signal). Fixed means cm-level accuracy. If it stays Single/Float, check mobile data, sky visibility, and that COMMON is selected. ### If the fix will not hold GINTEC G10 and KQ Geo K1 share a hardware platform and ship with a SurvX-family Android app (SurvX / SurPad / SurX by Shanghai eSurvey). Labels confirmed from the SurvX/SurPad 4.x guide, but minor wording differences exist between versions/rebrands - if a label doesn't match, use the closest equivalent ('Phone Network' vs 'Phone Internet', 'Get Mount Point' vs 'Get Access Point'). For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Hemisphere S631 / S321+ / S321 / Vega Connect a Hemisphere S631, S321+, S321 or Vega to RTK Premium corrections over NTRIP using Carlson SurvCE or SurvPC: caster settings and the steps to a fixed solution. These steps connect a Hemisphere S631 / S321+ / S321 / Vega to the Premium Positioning correction network over NTRIP, using Carlson SurvCE / SurvPC (or PocketMax). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hemisphere-s631-s321%2B-s321-vega) to get your credentials. * Carlson SurvCE / SurvPC (or PocketMax). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hemisphere-s631-s321%2B-s321-vega#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get the receiver internet-ready: You need a live internet path. Easiest: the data collector's own connection (its SIM or a phone/MiFi hotspot). The S631 also has a built-in 4G modem if you fit a SIM and set the APN. Power on and confirm it's tracking satellites. 2. Pair the receiver over Bluetooth: Pair the S631/S321 to the data collector via Bluetooth in the device OS first (it broadcasts under its serial number) so it's available to SurvCE/SurvPC. 3. Open Equip > GPS Rover: Launch Carlson SurvCE/SurvPC, open/start a job, then Equip > GPS Rover. Four tabs appear: Current, Comms, Receiver, RTK. 4. Set Manufacturer and Model (Current tab): Set Manufacturer to 'Hemisphere GNSS' and Model to 'S631' or 'S321'. List wording varies slightly by version - pick the closest Hemisphere entry. 5. Connect on the Comms tab: On Comms set Type to Bluetooth, select the paired S631/S321, and tap the green check / Connect. It reports a successful connection. 6. Choose the internet device (RTK tab): On the RTK tab set Device to 'Data Collector Internet' if the collector/phone provides the connection, or 'Internal GSM' if the SIM is in the receiver (tap the wrenches icon to set the APN). 7. Set Network to NTRIP: Set Network to 'NTRIP', then tap the wrenches icon next to Network to open the NTRIP Broadcasters screen. 8. Add the Premium Positioning caster: Tap New, name it (e.g. 'Premium Positioning'), and enter IP addr (Host) rtkpremium.xyz, Port 2101. 9. Enter YOUR NTRIP credentials: In User and Pwd type the username/password from your Premium Positioning welcome email - unique to you; never use anyone else's. 10. Download the source table: Tap the green check. SurvCE/SurvPC downloads the broadcaster's base list (source table). If nothing returns, recheck internet, host/port, and credentials. 11. Select the COMMON mountpoint: On the Bases screen open the Name dropdown and choose 'COMMON', then tap the green check. 12. Confirm and apply: Tap the green check again to return to the RTK tab. Correction type/format fields are greyed out on purpose - with NTRIP it follows what the caster advertises. Exit GPS Rover with the green check to start streaming. 13. Verify a Fixed solution: Go to Survey > Store Points and watch the status progress Autonomous → Float → FIXED (typically within a minute or two). Wait for FIXED before storing points, then check on a known mark. If you sit on Float, recheck cellular signal, the COMMON mountpoint, and your credentials. ### Steps with PocketMax 1. PocketMax alternative (if not using Carlson): If you set up corrections in Hemisphere PocketMax instead: Config > GNSS Rover > Corrections > NTRIP Client. Choose Controller Internet (or the receiver modem if SIM-equipped). Enter the same caster details - Address rtkpremium.xyz, Port 2101, Mountpoint COMMON - plus YOUR own credentials. Enable Send GGA, then Apply and wait for FIXED. PocketMax labels can vary by version - match by meaning. ### If the fix will not hold Names differ slightly between SurvCE and SurvPC versions and firmware; the layout is the same (Equip > GPS Rover, RTK tab, Network = NTRIP, wrenches icon to add the caster). Some crews drive the S631/S321 from Hemisphere's PocketMax app instead - there the path is Config > GNSS Rover > Corrections > NTRIP Client; caster host/port/mountpoint and your credentials are identical. A stable cellular signal is required; if correction age climbs above \~5 s the link is unstable. Auth errors usually mean a mistyped username/password. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Hi-Target Qmini A10 / V90 Connect a Hi-Target Qmini A10 or V90 to RTK Premium corrections over NTRIP using Hi-Survey Road: caster settings and the steps to a fixed solution. These steps connect a Hi-Target Qmini A10 / V90 to the Premium Positioning correction network over NTRIP, using Hi-Survey Road. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hi-target-qmini-a10-v90) to get your credentials. * Hi-Survey Road. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hi-target-qmini-a10-v90#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Insert a SIM or prepare phone data: NTRIP comes over the internet, so the rover needs a connection. Either insert a working data SIM in the receiver, or make sure the phone/tablet running Hi-Survey Road has mobile data or Wi-Fi. You choose which in a later step. 2. Power on and pair the receiver: Switch on the Hi-Target receiver (Qmini A10 / V90). On the phone/tablet, enable Bluetooth. The entry point varies slightly by app version but is usually under the 'Device' menu in Hi-Survey Road. 3. Connect to the receiver in Hi-Survey Road: Open Hi-Survey Road and go to Device > Connect (some versions 'Communication' or a device/antenna icon). Choose Bluetooth, set manufacturer to Hi-Target and device type to your model, search, then select your receiver's serial number to connect. Wait for confirmation. 4. Open the Work Mode / Rover setup: Under the Device menu open 'Work Mode' ('Mode' or 'Work Style' in some versions) and choose 'Rover'. Create a new rover mode or edit the existing one. 5. Set the Data Link to network/internet: In the rover mode settings, find 'Data Link' and select the internet option. SIM in the receiver: choose 'Receiver Network' (a.k.a. 'Receiver Mobile Network'). Using the phone/tablet's data: choose 'PDA Network'. Avoid the radio/UHF options. 6. Choose the NTRIP protocol: Set the connection protocol to 'NTRIP'. Some versions label this 'CORS' or list 'NTRIP' as a protocol within a CORS-type connection. Select NTRIP so you can enter a caster address and mount point. 7. Enter the caster address and port: In the 'IP' (server/domain) field enter rtkpremium.xyz. In 'Port' enter 2101. The same for every customer. If your version splits domain and IP, use the domain field for rtkpremium.xyz. 8. Enter YOUR NTRIP username and password: In 'Username' (User/Account) and 'Password', type the personal NTRIP login from your welcome email - unique to your account; do not reuse anyone else's. If you don't have them, contact support. 9. Retrieve the mount point list (source table): Tap the control that fetches the streams - a refresh icon, 'Get', or the dropdown next to 'Mount Point'. Hi-Survey Road connects and downloads the source table. If nothing loads, recheck IP, port, username, password, and your internet. 10. Select the COMMON mount point: From the mount point list, select COMMON - the stream all Premium Positioning customers use. If you don't see it, confirm the source table loaded and your credentials are correct. 11. Apply and confirm the settings: Save the rover mode with OK / Apply / Confirm (label varies). Hi-Survey Road sends the settings to the receiver and starts requesting corrections over your chosen network. 12. Wait for a Fixed solution: Watch the solution status (top status bar or the satellite/solution indicator): Single → Float → Fixed (often green), usually within seconds to a couple of minutes outdoors with clear sky. 'Fixed' means full RTK accuracy. If it stays Single/Float, check internet signal, that COMMON is selected, and your credentials. ### If the fix will not hold Menu/button names differ slightly between Hi-Survey Road versions (and the similar 'SurvY' app) - match the closest equivalent (Work Mode/Mode, Data Link/Datalink, Receiver Network/Receiver Mobile Network). Note: the standard Qmini A10 (CM) may have limited or no native NTRIP support in some app builds - if the network/NTRIP data-link option is missing, contact Premium Positioning to confirm your unit and firmware. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Hi-Target V200 / iRTK5 / vRTK Connect a Hi-Target V200, iRTK5 or vRTK to RTK Premium corrections over NTRIP using Hi-Survey Road: caster settings and the steps to a fixed solution. These steps connect a Hi-Target V200 / iRTK5 / vRTK to the Premium Positioning correction network over NTRIP, using Hi-Survey Road. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hi-target-v200-irtk5-vrtk) to get your credentials. * Hi-Survey Road. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hi-target-v200-irtk5-vrtk#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Switch on the V200 / iRTK5 / vRTK and wait for a solid satellite LED. Open Hi-Survey Road, go to the Device tab, tap Connect (sometimes 'Communication'), choose Bluetooth, search, and select your receiver's serial number. Confirm it shows connected. 2. Open a project: Open Project, create/open a project and confirm the coordinate system / datum is correct for your work. The network supplies corrections in a global frame; an incorrect local system gives a Fixed solution in the wrong place, so set this before measuring. 3. Set the receiver as a Rover (Work Mode): Go to Device > Work Mode (some versions 'Workmode' or 'Survey Mode') and choose Rover (Mobile Station). 4. Choose the data link = network/CORS: In the Rover work-mode settings open Data Link and choose a network link. Wording varies: 'Receiver Network' / 'Internal Network' uses a SIM in the receiver; 'PDA Network' / 'Phone Network' / 'Data Collector Internet' uses the controller's/phone's internet. Pick the one matching how you have internet. 5. Set the protocol to NTRIP: Set the protocol / connection type to NTRIP (not APIS or TCP/Direct). Premium Positioning is a standard NTRIP caster. 6. Enter the caster server and port: Add a new server (save it in the Server list for reuse) and enter Server / IP / Domain: rtkpremium.xyz and Port: 2101. Modern Hi-Survey versions accept a domain; if yours rejects it, contact Premium Positioning for the numeric IP. 7. Enter YOUR NTRIP username and password: In User / Username and Password enter the credentials from your Premium Positioning welcome email - unique to your account. Type them exactly, watching case sensitivity and trailing spaces. 8. Retrieve the source table (mount point list): Tap the control that fetches mount points - a refresh/reload icon next to the Mount Point field, or a button labelled 'Get' / 'Get Source' / 'Access Point'. The receiver connects to rtkpremium.xyz:2101 and downloads the source table. If empty, your address/port/credentials are wrong or there's no internet. 9. Select the COMMON mount point: From the Mount Point list select COMMON - Premium Positioning's correction stream. Make sure it's the highlighted/selected entry. 10. Apply and connect: Confirm with Set / OK / Apply. Hi-Survey Road sends your position (NMEA GGA) up to the caster and pulls corrections back. Look for an incoming-data / 'connected' indicator and a steadily updating correction age. 11. Check the solution status: Return to the survey/measure screen and watch the status progress Single → Float (Differential) → Fixed. Keep the antenna in open sky during this step. 12. Confirm a Fixed solution before measuring: Don't record points until the status reads Fixed with cm-level precision and a low correction age (ideally under \~3 s). If it stays Float or Single, recheck credentials, mount point, internet, and that you have open sky. ### If the fix will not hold Labels differ between Hi-Survey Road versions and firmware - the data-link names ('Receiver Network' vs 'PDA Network' / 'Phone Network' / 'Data Collector Internet') and the source-table button ('Get' / 'Get Source' / refresh icon) in particular vary, so match by function. Use the receiver's own SIM ('Receiver Network') only if a data SIM is installed; otherwise use the controller/phone internet option. For a reliable Fixed, work in open sky, keep correction age low, and ensure the project coordinate system is correct so the Fixed position lands in the right place. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # iGage iG8 / iG9 Connect an iGage iG8 or iG9 to RTK Premium corrections over NTRIP using Carlson SurvCE or SurvPC: caster settings and the steps to a fixed solution. These steps connect an iGage iG8 / iG9 to the Premium Positioning correction network over NTRIP, using Carlson SurvCE / SurvPC. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=igage-ig8-ig9) to get your credentials. * Carlson SurvCE / SurvPC. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=igage-ig8-ig9#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get an internet connection ready: NTRIP corrections come over the internet, so the data collector running SurvCE/SurvPC needs to be online - its own SIM, or a Wi-Fi hotspot from your phone. (The iG8/iG9 can also use its own internal SIM, but data-collector internet is simplest.) Confirm signal at the job site. 2. Open Equip > GPS Rover: Launch SurvCE/SurvPC. From the main menu tap Equip > GPS Rover. The dialog has four tabs: Current, Comms, Receiver, RTK - fill them left-to-right. 3. Set Manufacturer and Model (Current tab): Set Manufacturer and Model to match your receiver. iGage hardware is rebranded CHCNAV, so depending on SurvCE/SurvPC version the iG8/iG9 is under an iGage profile or the CHC/CHCNAV manufacturer - pick whichever your version lists. Tap Save to store it. 4. Connect to the receiver (Comms tab): On Comms set Type to Bluetooth, find and pair your receiver, and connect. Wait until it reports connected. 5. Check antenna and rover settings (Receiver tab): Set Antenna type and Antenna Height to match the pole mounting (and the measurement method). Accurate height is essential for correct elevations. Set the elevation mask if prompted. 6. Set Device and Network on the RTK tab: On RTK set Device to Data Collector Internet (use Internal GSM only if the SIM is in the receiver), then set Network to NTRIP. 7. Open the NTRIP Broadcasters dialog: Tap the wrenches/gears icon next to Network to open the NTRIP Broadcasters window. 8. Add Premium Positioning's caster (New): Tap New, name it 'Premium Positioning', and enter IP addr (Host) = rtkpremium.xyz, Port = 2101 - the same for every customer. 9. Enter YOUR NTRIP username and password: Type the User name and Password (Pwd) from your welcome email - unique to you; do not use anyone else's. If you don't have them, contact Premium Positioning first. 10. Download the base list (green check): Tap the green check to save the broadcaster and connect. SurvCE/SurvPC reaches rtkpremium.xyz and downloads the list of bases (mountpoints). 11. Select the COMMON mountpoint: From the list choose COMMON, then tap the green check. (With NTRIP the correction format is handled automatically - the iG8/iG9 auto-detects RTCM.) 12. Confirm and verify FIXED: Tap the green check again to close GPS Rover and start streaming. Go to Survey > Store Points and watch the quality indicator climb Autonomous/Single → FLOAT → FIXED. Record points only once FIXED, and shoot a known check point to confirm. ### If the fix will not hold iGage receivers are rebranded CHCNAV, so in some SurvCE/SurvPC versions the iG8/iG9 is selected under the CHC/CHCNAV manufacturer; pick the closest iGage or CHC iG8/iG9 profile. Tab labels, the Device dropdown wording, and the NTRIP Broadcasters icon (wrenches/gears) differ slightly between versions; the order and meaning are the same. If you never reach FIXED, recheck credentials, that the collector still has internet, and that COMMON is selected. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Kolida K5 / K9T / K1 Pro Connect a Kolida K5, K9T or K1 Pro to RTK Premium corrections over NTRIP using SurvX or SurvStar: caster settings and the steps to a fixed solution. These steps connect a Kolida K5 / K9T / K1 Pro to the Premium Positioning correction network over NTRIP, using SurvX / SurvStar (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet?

If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=kolida-k5-k9t-k1-pro#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. About this app: Kolida receivers run a SurvX-family Android app (SurvX / SurvStar), sharing the same SOUTH lineage and menu structure as SOUTH SurvX and SurPad. Labels below match SurvX 4.x; wording varies slightly between versions/translations - match the nearest equivalent. 2. Power on and pair: Turn on the Kolida K5 / K9T / K1 Pro and enable Bluetooth on your Android device. You don't have to pair in Android settings first; SurvX can pair during connection. 3. Open Device > Communication: In SurvX open Device > Communication. Set the device manufacturer/type to your Kolida receiver and choose Bluetooth. 4. Connect over Bluetooth: Tap Search. When your receiver's serial number appears in the Bluetooth Device List, tap it then Connect (tap Pair if prompted). Wait for connected status. 5. Open Device > Rover: Go to Device > Rover to open the rover mode settings - where you choose how corrections reach the receiver. 6. Choose the Data Link: In Data Link choose Device Internet (receiver's own SIM/modem) or Phone Internet (your Android device's mobile data). Either works for NTRIP; pick whichever has a data connection. 7. Set Connect Mode to NTRIP: Set Connect Mode (protocol) to NTRIP. Leave the GGA upload interval at its default unless told otherwise. 8. Enter the caster address and port: In CORS / server settings: Server / IP / address: rtkpremium.xyz, Port: 2101 - the same for every customer. 9. Enter YOUR NTRIP username and password: In CORS Settings enter the NTRIP User and Password from your welcome email - unique to you; do not share them. 10. Get the source table: In Mount Point Settings tap Get Mount Point (shown as Get Access Point when using Phone Internet) to retrieve the source table using your credentials. 11. Select mount point COMMON: From the list choose COMMON. Confirm/apply to start receiving corrections. 12. Confirm a Fixed solution: On the survey/map screen watch the status move Single → Float → Fixed (top status bar). Once Fixed, the receiver is on the network and ready for cm work. If it stays Single/Float, recheck the data link, credentials, mount point, and your mobile data. ### If the fix will not hold Kolida's SurvX / SurvStar is part of the SOUTH SurvX/SurPad software family, so these steps broadly apply to SOUTH and other SurvX-based controllers. Labels may differ slightly by app version; match the closest equivalent.

These steps connect a Leica GS18 T / GS18 I / GS16 / GS07 to the Premium Positioning correction network over NTRIP, using Leica Captivate (CS20 controller). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-gs18-t-gs18-i-gs16) to get your credentials. * Leica Captivate (CS20 controller). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-gs18-t-gs18-i-gs16#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Turn on the GS18/GS16 and the CS20 controller. In Leica Captivate, make sure the controller is connected to the GS receiver (it should appear connected on the Home screen). Confirm you're in a job/coordinate system before starting RTK. 2. Get the controller online: From Captivate Home go to Settings > Connections and open the internet connection setup ('Internet connection' / 'GS connects to internet' depending on version). Use the CS20 SIM/cellular or a Wi-Fi hotspot. The rover needs working internet before it can reach the caster. 3. Open the RTK rover setup: From Captivate Home go to Settings > Connections and open the RTK rover connection ('RTK rover wizard', or 'GS RTK rover' / 'RTK Network profile' in newer versions). Create a New profile (or copy an existing one). Set the RTK rover to connect via the Internet. 4. Create the RTK / NTRIP profile: Name the profile (e.g. 'Premium Positioning'). When asked for the connection/data device, choose the controller's internet connection so corrections come over the Internet rather than a radio. 5. Set the connection type to NTRIP: For the network/server type choose NTRIP (in some versions the choices are 'NTRIP' vs 'Direct IP' - select NTRIP). 6. Enter the caster server and port: Create a New server and enter Host / Server: rtkpremium.xyz and Port: 2101. Leave the protocol as NTRIP. Save the server so it can be reused. 7. Enter YOUR NTRIP username and password: Enter the NTRIP User ID and password from your Premium Positioning welcome email - unique to your account; do not use anyone else's. 8. Select the mountpoint: Use COMMON. If Captivate offers 'Select mountpoint from source table', loading it also confirms the login works - pick COMMON. If the source table is slow or comes back empty, type COMMON manually in capitals; with large source tables this is normal Captivate behaviour, not an error. 9. Turn on Send GGA position: Set 'Send GGA position' to On or Automatic - the COMMON mount needs your rough position to compute corrections. If this is off you may stay on Float and never reach Fixed. 10. Finish and save the profile: Step through the remaining wizard pages (PIN/PUK and device questions can stay default for a standard internet rover), confirm the summary, and press Next/Finish (F6) to save. 11. Start the connection: Select your saved RTK profile to start it. Watch for 'Connected to internet' then 'Connected to NTRIP caster'. If login fails, recheck the username/password and that the host is rtkpremium.xyz on port 2101. 12. Confirm an RTK Fixed solution: Watch the status bar progress Navigated/Autonomous > Float > Fixed, with Coordinate Quality (CQ) dropping to cm level. If it stalls on Float, check Send GGA is on, you have clear sky, and your internet is stable. ### If the fix will not hold Menu/button names vary between Captivate versions (e.g. 'RTK rover wizard' vs 'GS RTK rover' / 'RTK Network profile') - match by meaning. If you can't reach Fixed, the usual causes are an offline controller, wrong/blank credentials, Send GGA off, or poor sky view. Distinct from the Leica iCG70 entry, which is the iCON machine-control line. The same workflow applies to GS16 and GS07 on a CS20. Tip: if the source table is slow or empty, the internet connection usually isn't up yet - fix that first, or type COMMON manually.

These steps connect a Ruide R6P / Nova to the Premium Positioning correction network over NTRIP, using SurvX / SurvStar (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=ruide-r6p-nova) to get your credentials. * SurvX / SurvStar (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=ruide-r6p-nova#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Before you start: Power on the Ruide R6P/Nova and your Android device. Make sure the phone has mobile data (SIM) or Wi-Fi - corrections arrive over the internet. Have your NTRIP username/password from your welcome email ready. 2. Open SurvX (a SurvX-family app): Ruide rebadges a SurvX-family app (SOUTH/SurPad lineage, sometimes branded SurvStar), so this workflow applies directly - menu names match even if the splash logo differs. Open the app and continue or create a project. 3. Connect to the receiver over Bluetooth: Go to Device > Communicate. Set Device type to your Ruide/SOUTH receiver, Connect type to Bluetooth, tap Search/Connect Config, pick your receiver's serial number, then Connect. Pair first in Android Bluetooth settings if it doesn't appear. 4. Open the Rover configuration: Go to Device > Rover, where the receiver is set as a network rover and the NTRIP source is defined. Edit the current working mode or add a new one. 5. Set the Data Link to a network connection: Set Data Link: Receiver Network (receiver's internal SIM/modem) or Phone Network / PDA Network (corrections via the phone's internet over Bluetooth). Phone Network with mobile data is simplest. Wording ('PDA Network' vs 'Phone Network') varies by version. 6. Choose the NTRIP protocol: Set the Protocol / Server type to NTRIP (some versions label this CORS for a single-mountpoint caster). This exposes the caster address, port and login fields. 7. Enter the Premium Positioning caster details: Server/IP: rtkpremium.xyz, Port: 2101, Protocol: NTRIP. You can type rtkpremium.xyz directly in the IP/Address field; the app resolves the domain. 8. Enter YOUR NTRIP username and password: Type the credentials from your Premium Positioning welcome email - unique to your account; don't guess. If lost, contact support for a reset. 9. Retrieve the source table: Tap Get Access Point (also 'Get Source Table' / the refresh icon). The app connects to rtkpremium.xyz:2101, authenticates, and downloads the mountpoints. 10. Select the COMMON mountpoint: From the access-point / Mount Point list select COMMON - the Premium Positioning correction stream. Confirm your selection. 11. Apply and start corrections: Tap OK / Apply (and Start/Confirm if prompted) to send the config to the receiver and begin streaming. A progress bar fills and the data icon animates. 12. Confirm a Fixed solution: Watch the top status bar or Device > Device Status progress Single → Float → Fixed. Fixed with a low, stable HRMS/VRMS (a few cm or better) means you're receiving corrections correctly. If it stays Single/Float, re-check internet, credentials, and that COMMON is selected. ### If the fix will not hold Ruide rebadges a SurvX-family Android app (SOUTH/SurPad/SurvStar lineage), so the standard SurvX network-rover flow applies. Minor wording ('Phone Network' vs 'PDA Network', 'NTRIP' vs 'CORS') varies between versions. Caster host/port/mountpoint are the same for all customers; only your username/password are personal and are entered on the device. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Sanding T11 / T20 Connect a Sanding T11 or T20 to RTK Premium corrections over NTRIP using SurvX: caster settings and the steps to a fixed solution. These steps connect a Sanding T11 / T20 to the Premium Positioning correction network over NTRIP, using SurvX (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sanding-t11-t20) to get your credentials. * SurvX (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sanding-t11-t20#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Before you start: Have your Premium Positioning NTRIP username and password ready (from your welcome email). Power on the Sanding receiver, make sure the Android device running SurvX has mobile data or Wi-Fi, and that the receiver is charged. These steps follow the standard SurvX / SurPad 4.x workflow; wording may vary slightly by version. 2. Open Device > Communication: In SurvX, from the main menu tap Device, then Communication. Set the manufacturer and device type to match your Sanding receiver, then choose Bluetooth as the communication mode. 3. Pair and connect to the receiver: Tap Search to scan. When your Sanding unit's serial appears in the Bluetooth Device List, tap Stop, select that device, then tap Connect. On first connection tap Pair on the Android prompt. Wait until SurvX shows connected. 4. Open Device > Rover: From the main menu tap Device, then Rover, to open the Rover mode settings (sets the receiver to receive corrections, not Base or Static). 5. Open the Data Link settings: In the Rover screen, tap Data Link. For internet (NTRIP), choose Device Internet to use the receiver's own SIM/network, or Phone Internet to send corrections through your Android phone's data. Phone Internet is simplest if the receiver has no SIM. 6. Set the connection mode to NTRIP: In the Connect Mode area, set it to NTRIP (the standard mode for CORS networks). Leave GGA upload interval at the default (\~5 seconds). 7. Enter the caster address and port: In CORS Settings, open the server/customize option (the add or edit button) and enter the caster: Server / IP rtkpremium.xyz, Port 2101, Protocol NTRIP. Save the server entry. 8. Enter YOUR NTRIP username and password: Still in CORS Settings, fill in the NTRIP user and Password from YOUR welcome email - unique to your account; do not share or reuse someone else's. 9. Retrieve the mount point list: In MountPoint Settings, tap Get Mount Point (shown as Get Access Point when the data link is Phone Internet). SurvX connects and downloads the source table. If nothing loads, re-check host, port, credentials, and your internet connection. 10. Select the COMMON mount point: From the downloaded source table, select COMMON - the correct mount point for all Premium Positioning customers. 11. Apply the settings: Confirm the mount point selection, then return to the Rover screen and tap Apply. SurvX starts requesting corrections from the caster. 12. Confirm a Fixed solution: Return to the main map/survey screen and watch the solution status in the top status bar: Single → Float → Fixed within roughly 10 - 60 seconds outdoors with clear sky. Fixed means cm-level RTK and you're ready to survey. If it won't fix, check open sky, internet, host/port (rtkpremium.xyz:2101), mount point COMMON, and that your username/password were typed exactly. ### If the fix will not hold Sanding T11 / T20 receivers run the SurvX (also branded SurPad) Android app. Menu paths/labels here are from the SurvX 4.2 / SurPad 4.2 user guide and match the standard SurvX flow; minor differences may exist between app versions and Sanding firmware. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # SatLab SLC / Eyr Connect a SatLab SLC or Eyr to RTK Premium corrections over NTRIP using SatSurv: caster settings and the steps to a fixed solution. These steps connect a SatLab SLC / Eyr to the Premium Positioning correction network over NTRIP, using SatLab field app (SatSurv / SurvX-style). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=satlab-slc-eyr) to get your credentials. * SatLab field app (SatSurv / SurvX-style). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=satlab-slc-eyr#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and pair over Bluetooth: Switch on the SatLab SLC/Eyr and enable Bluetooth on your Android controller. Open the SatLab field app (SatSurv) and go to the device/connection screen (Device > Connect or the Communication tab). Set Manufacturer to SatLab, choose Bluetooth, search and select your receiver by serial number. Confirm connected status. 2. Open Rover settings: Go to Device (or Config) and choose Rover (in the SLC docs reached via GPS Base/Rover settings; in SatSurv the Rover work mode). Always pick Rover, not Base. 3. Set the Data Link to network/internet: Set the Data Link to a network internet option, not radio. The controller's connection is usually Phone Network / PDA Network (its SIM or Wi-Fi); the receiver's own modem is Receiver Network (in the SLC manual: Internal GSM vs Data Collect Internet). Pick the device that actually has internet. These labels can vary by SatSurv version. 4. Select the NTRIP protocol: Select NTRIP for the connection type (some SurvX-style screens label this CORS, which is the same NTRIP-client mode). Don't pick TCP/APIS or radio. 5. Enter the caster server and port: Server/Host = rtkpremium.xyz, Port = 2101. Leave any TLS/SSL toggle off unless told otherwise - this caster uses standard NTRIP on port 2101. 6. Enter YOUR NTRIP username and password: Enter the username/password from YOUR welcome email - unique to your account, case-sensitive. They're entered into the device only and never sent to anyone else. 7. Retrieve the source table (mountpoint list): Tap the button that fetches streams - Get Access Point, Get Source Table, or a refresh icon next to the mountpoint field. If the list comes back empty, re-check server, port, credentials and that the device has internet. 8. Select the COMMON mountpoint: From the source-table list select COMMON - the Premium Positioning correction stream. Confirm/OK to save it into the NTRIP profile. 9. Apply and connect: Confirm the settings (OK/Apply). The app connects and requests corrections. On the SLC/Eyr a successful link shows the signal LED solid green, flashing yellow as data is received. 10. Confirm a Fixed solution: On the survey/status screen watch Single → Float → Fixed (the app shows the solution state, e.g. RTK Fixed). Wait for Fixed with cm accuracy before recording points. If it stays Float, allow open-sky time and verify the mountpoint and coverage. ### If the fix will not hold The SatLab app (SatSurv) is a SurvX-style Android app: connect/Rover/Data Link/NTRIP labels are confirmed in the SatLab SLC manual and the standard SurvX/SurvCE flow these apps share, but some wording (Phone Network vs PDA Network, Get Access Point vs Get Source Table) varies slightly between versions - pick the option matching the description. A Fixed solution needs clear sky and a stable internet connection. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Septentrio Altus NR3 Connect a Septentrio Altus NR3 to RTK Premium corrections using its built-in NTRIP client or a field app: caster settings and the steps to a fixed solution. These steps connect a Septentrio Altus NR3 to the Premium Positioning correction network over NTRIP, using Built-in NTRIP client (web UI) or a paired Android/iOS field app. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=septentrio-altus-nr3) to get your credentials. * Built-in NTRIP client (web UI) or a paired Android/iOS field app. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=septentrio-altus-nr3#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Have your credentials ready: You'll need the NTRIP username and password from your Premium Positioning welcome email - unique to your account. 2. Power on and pick your path: Power up the Altus NR3 and wait for satellite tracking. Two common paths: (A) the receiver's built-in NTRIP client via its web interface, or (B) a paired Android/iOS field app (e.g. Carlson SurvCE/SurvPC, or a generic NTRIP/GIS app) over Bluetooth. Both are covered below. 3. Path A - connect to the web interface: Connect your phone/laptop to the receiver's Wi-Fi access point (SSID is usually the serial/model name; see the label for the password). Open a browser to (Wi-Fi) or (USB/Ethernet). The IP can vary by firmware - check your quick guide if neither loads. 4. Path A - set the receiver as an RTK rover: In the web interface confirm the receiver is in rover mode with RTK enabled - NTRIP corrections won't promote to RTK Fixed otherwise. 5. Path A - open the NTRIP client: Go to the Corrections menu and select NTRIP (on some firmware this is under Communication), then click New NTRIP client. Wording varies by firmware - look for the NTRIP / corrections-input section. 6. Path A - enter the caster and port: Set the caster Host/Server to rtkpremium.xyz and Port to 2101. Ensure the mode/type is NTRIP client. 7. Path A - enter your credentials: Type YOUR NTRIP Username and Password from the welcome email. Watch for stray spaces or typos - the most common cause of a failed connection. 8. Path A - select the mountpoint: With the caster details correct, the receiver retrieves the source table. Choose mountpoint COMMON, then OK / Apply. Tip: enable 'save to boot' so it auto-reconnects after power-cycles. 9. Path B - connect the field app over Bluetooth: In your field app, pair with the Altus NR3 over Bluetooth (in Carlson: Equip > GPS Rover > Comms tab > Bluetooth, then Find/select the NR3). Confirm it's configured as a rover with RTK on. 10. Path B - choose NTRIP as the correction source: On the rover RTK / correction settings, set the data link to your internet source (internal cellular/GSM or the phone's connection) and Network to NTRIP. Open the NTRIP settings dialog. Labels vary by app - the option you want is the NTRIP network correction source. 11. Path B - enter caster, port, credentials and mountpoint: Enter Host rtkpremium.xyz, Port 2101, your NTRIP Username/Password, protocol NTRIP. Load/refresh the source table and select COMMON, then save/connect. If no table loads, re-check host, port and internet. 12. Confirm you have RTK Fixed: Allow a few seconds for corrections to flow. In the web UI the NTRIP link shows active with incoming data and position mode reads RTK fixed. In a field app the status moves Autonomous/DGPS → Float → Fixed. Once you see RTK Fixed with cm accuracy, you're set. ### If the fix will not hold Exact menu names, the Wi-Fi SSID/password, and the web-interface IP differ by firmware and field app - if a label doesn't match, look for the equivalent NTRIP/corrections option or check your unit's quick guide. If you can't get past Float to Fixed, verify credentials (watch for typos/spaces), confirm internet, and that the receiver is in rover mode with RTK enabled. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Sokkia GCX3 / GCX2 Connect a Sokkia GCX3 or GCX2 to RTK Premium corrections over NTRIP using MAGNET Field: caster settings and the steps to a fixed solution. These steps connect a Sokkia GCX3 / GCX2 to the Premium Positioning correction network over NTRIP, using MAGNET Field. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sokkia-gcx3-gcx2) to get your credentials. * MAGNET Field. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sokkia-gcx3-gcx2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Switch on the GCX3/GCX2 and your controller. In MAGNET Field the receiver normally connects over Bluetooth (some controllers use a cable). If not already paired, pair them via the controller's Bluetooth settings first. 2. Open Configure > Survey: From the main screen tap Configure, then the Survey icon, to open the survey configuration list (GPS+ and Total Stations). 3. Create a new configuration: Tap Add for a new configuration (or Edit an existing Network RTK config). Name it e.g. 'PP Network RTK'. Set Type to 'Network RTK'. 'Corrections' can stay at its default (e.g. VRS) for our single COMMON mount point. 4. Set the receiver make: On Receiver Make / Manufacturer set Manufacturer to 'Topcon' (the GCX3/GCX2 use the Topcon/Sokkia profile in MAGNET). Leave Simulation Mode and Post Processing unchecked. Tap Next. 5. Configure the Rover Receiver: On Rover Receiver: keep 'Ext. Receiver' on your connection (e.g. Bluetooth), set Receiver Model to your unit (GCX3 or GCX2 - pick the closest listed), set an Elevation Mask (10 - 13 deg typical), and set Antenna to match. Tap Next. 6. Select NTRIP as the protocol: In the rover/correction settings set Protocol to 'NTRIP', so MAGNET receives corrections from a caster over the internet rather than a UHF radio. 7. Set the data connection (Modem Connect): On 'Config: Modem Connect' set Modem Connect to 'Controller' (sometimes 'Controller Internet' / 'Data Collector Internet') to route the internet through the controller's SIM/Wi-Fi. (Choose 'Receiver' only if using a SIM inside the receiver.) Tap Next. 8. Enter the caster address and port: On 'Config: Modem Internet Info', in Address enter the caster as host:port - rtkpremium.xyz:2101. Tap Add new, set the selector to 'Web' (host name) not 'IP', and ensure the new entry is selected. Tap Next. (Host: rtkpremium.xyz, Port: 2101.) 9. Enter YOUR NTRIP username and password: On 'Config: Login Info', enter the NTRIP User ID and Password from your welcome email - unique to your account; do not share them. Tap Next. 10. Select the COMMON mount point: MAGNET requests the caster's source table when it connects. When prompted to choose a mount point, select COMMON. The label/timing varies by version - on some there's a dropdown or 'Get/Request source table' on the internet screen; on others the table appears when you start the survey. Either way, pick COMMON. (Mount point: COMMON, Protocol: NTRIP.) 11. Set the survey parameters: Continue through Topo Survey / Stake. Set Solution to 'Fixed Only' so points store only on a fixed solution. Adjust tolerances as needed, then continue. On Advanced, GPS+GLONASS (or all constellations) and 'Automatic Detection' for base make are sensible. 12. Finish and save the configuration: Step through Miscellaneous ('Auto-connect to server' is handy) and tap the green check to save. Return to the list with your new config; tap the green check again to make it the active configuration. 13. Connect and start the survey: Start the survey (Survey > Topo, or Connect). MAGNET dials the caster, authenticates, and streams corrections from COMMON. The data-link/age-of-corrections indicator becomes active. 14. Confirm a Fixed solution: Watch the solution status go Autonomous/Standalone → Float → Fixed. Once 'Fixed' with low HRMS/VRMS, you're connected and can survey or stake. If it stalls at Float, recheck your credentials, rtkpremium.xyz:2101, the COMMON mount point, and your internet signal. ### If the fix will not hold The GCX3 and GCX2 use the Topcon/Sokkia profile in MAGNET Field, so screens are essentially identical for both. Menu/button labels (how the mount point/source table is selected, 'Controller' vs 'Controller Internet') vary between MAGNET versions - follow the equivalent option. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Sokkia GRX3 / GRX2 to the Premium Positioning correction network over NTRIP, using MAGNET Field (SHC-series controller). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sokkia-grx3-grx2) to get your credentials. * MAGNET Field (SHC-series controller). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sokkia-grx3-grx2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Switch on the GRX3/GRX2 and the SHC controller, open MAGNET Field, and open or create a job. Tap the Connect (receiver/antenna) icon, choose Bluetooth (or Cable), select your receiver from the device list, and confirm it shows connected. 2. Open the configuration list: Tap Configure > Survey > Configurations to open the list of survey configurations. Tap Add for a new one, or select a Network RTK configuration and tap Edit. (The Configure sub-menu wording varies a little by version - look for the RTK/survey-style section.) 3. Name it and set Type to Network RTK: Give it a clear name (e.g. 'Premium Positioning NTRIP') and set Type/Style to Network RTK - not single-base or radio. Leave Simulation Mode unchecked. 4. Select receiver model and corrections format: Set Receiver Model to your unit (GRX3 or GRX2). Use RTCM 3.x as the correction format. If asked for a network sub-type, leave the default for a standard single-mountpoint caster. 5. Set the connection Protocol to NTRIP: On the network/RTK page set Protocol (sometimes 'Network type' or 'Data type') to NTRIP so MAGNET requests a source table and connects to a named mountpoint. 6. Choose how the controller reaches the internet: Set Modem Connect = Controller to use the SHC controller's own cellular/Wi-Fi (most common - confirm it has data first), or Receiver if the SIM is inside the GRX3. On some versions this is 'Controller with Internal Cellular' vs 'Receiver with Internal Cellular'. 7. Set the antenna and rover height: On the Antenna page select the correct GRX3/GRX2 antenna, enter the antenna/pole height and the measurement type (vertical to ARP, or slant). An incorrect height is the most common cause of a vertical offset. 8. Enter the caster address and port: In the internet/NTRIP server settings enter Server / Host: rtkpremium.xyz (choose the Web option if there's an IP-vs-host toggle) and Port: 2101. Protocol stays NTRIP. 9. Enter YOUR NTRIP username and password: Enter the personal NTRIP credentials from your Premium Positioning welcome email - unique to your account; do not use anyone else's. 10. Retrieve the source table (mountpoint list): Tap the control that fetches mountpoints - the drop-down arrow beside the mountpoint field, a Get/Update button, or it loads automatically once address, port and credentials are entered. 11. Select the COMMON mountpoint: Select COMMON from the list. If you see 'no mount point to connect to automatically', tap the drop-down and choose COMMON. Save/accept the configuration. 12. Start the survey and connect: Back at the Configurations list, ensure your Network RTK configuration is the active one, then start a survey (Survey > Topo). MAGNET dials out, verifies your credentials, and you'll see a 'Data received' message. 13. Confirm a Fixed solution: Watch the solution status progress Autonomous → Float → Fixed. Only store points once it reads Fixed and HRMS/VRMS are within tolerance. If it stays Float, check sky view, mobile signal, and that COMMON and your credentials are correct. ### If the fix will not hold Sokkia receivers use the same MAGNET Field software as Topcon, so any Topcon MAGNET Field NTRIP guide also applies. Menu/button wording (the Configure sub-menu, the internet/Rover Radio screen, the 'Get mountpoints' control) varies slightly between MAGNET versions and controllers (e.g. SHC5000) - match the equivalent option. A Fixed solution needs clear sky and a working data/Wi-Fi connection on the controller (or a SIM in the receiver).

These steps connect a South Galaxy G1 / G6 / G7 / Insight2 to the Premium Positioning correction network over NTRIP, using SurvX (or Survey Master / SurvStar). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=south-galaxy-g1-g6-g7-insight2) to get your credentials. * SurvX (or Survey Master / SurvStar). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=south-galaxy-g1-g6-g7-insight2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and get an internet path: Turn on the South Galaxy receiver and your controller running SurvX. NTRIP corrections come over the internet, so you need a connection: either the controller's mobile data / Wi-Fi (simplest, most common) or a SIM in the receiver. Confirm the controller can reach the internet before continuing. 2. Open SurvX and create/open a job: Launch SurvX (some regions ship Survey Master or SurvStar - same workflow). The main menu shows \[Project], \[Device], \[Survey], \[Tools]. Open \[Project] and create/open a job, setting the correct coordinate system first - corrections are WGS84 and the job's datum determines your displayed coordinates. 3. Connect the controller to the receiver: Go to \[Device] → Communication. Set Manufacturer to South and the model to your Galaxy unit, set connection to Bluetooth, tap Search, select your receiver's serial number and Connect. If pairing is requested, pair in the controller's Android Bluetooth settings first. 4. Set the receiver to Rover mode: In \[Device] open Rover ('Set as Rover'). This configures the Galaxy to consume corrections rather than act as a base. Keep the default RTK message format - the COMMON stream is standard RTCM 3.x, which the Galaxy auto-detects. 5. Choose the Network data link: On the Rover settings, set Datalink to a network/internet option: 'PDA Network' / 'Phone Internet' if the controller has the SIM/Wi-Fi, or 'Receiver Network' if the SIM is in the Galaxy. Choose the network entry, not Radio. Wording varies across SurvX/Survey Master/SurvStar. 6. Set the protocol to NTRIP (CORS): Set the connection Protocol/mode to NTRIP. In South software this network-correction profile is often labelled CORS, with NTRIP as the underlying protocol. Choose NTRIP/CORS rather than TCP/APIS. 7. Enter the caster address and port: In the IP / Server (Address) field enter rtkpremium.xyz and in Port enter 2101. Enter the hostname where text is allowed; protocol stays NTRIP. 8. Enter YOUR NTRIP username and password: In User Name and Password type the personal NTRIP credentials from your Premium Positioning welcome email - unique to your account. SurvX can save them to a profile for next time. 9. Retrieve the mountpoint (source table): Tap the refresh/source-table control - a circular refresh icon next to the mountpoint field, or a button labelled 'Get Access Point' / 'Get source list' / 'Get Mount Point'. SurvX connects to rtkpremium.xyz:2101 and lists the mountpoints. If empty, re-check server, port, credentials and that the controller is online. 10. Select the COMMON mountpoint: From the mountpoint list select COMMON - Premium Positioning's correction stream. Confirm so it's written into the data-link profile. 11. Apply and start the rover link: Tap OK / Apply / Connect to start the NTRIP link. SurvX logs in, requests COMMON, and feeds RTCM corrections to the Galaxy. A small data/connection indicator becomes active. 12. Confirm a Fixed solution: Open \[Survey] or watch the status bar. The solution progresses Single → Float → Fixed, normally within 10 - 30 seconds once corrections flow. Wait for Fixed with a low HRMS/VRMS (typically 1 - 2 cm) before storing points. If it stays Single/Float, check internet, the COMMON selection, and your credentials. ### If the fix will not hold Labels differ slightly across SurvX, Survey Master and SurvStar and across versions - the network data-link entry may read 'PDA Network'/'Phone Internet' (controller SIM/Wi-Fi) or 'Receiver Network' (receiver SIM), and the mountpoint-fetch control may be a refresh icon or a 'Get Access Point' button. A Fixed solution needs clear sky and a stable internet connection; under canopy or in urban canyons, fixing may take longer or be intermittent. Button/field names vary between SurvX/SurvStar versions (Data Link vs Datalink, Get Access Point vs Get Mount Point, CORS Settings vs Connect/Network settings, Phone Internet vs Receiver/Device Internet) - match by function: connect over Bluetooth, choose an internet data link, set protocol NTRIP, enter caster+port and your credentials, download the source table, select COMMON. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Spectra SP85 / SP80 / SP60 / SP30 Connect a Spectra SP85, SP80, SP60 or SP30 to RTK Premium corrections over NTRIP using Survey Pro or Origin: caster settings and the steps to a fixed solution. These steps connect a Spectra SP85 / SP80 / SP60 / SP30 to the Premium Positioning correction network over NTRIP, using Survey Pro / Spectra Geospatial Origin (FAST Survey on older kit). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-sp85-sp80-sp60-sp30) to get your credentials. * Survey Pro / Spectra Geospatial Origin (FAST Survey on older kit). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-sp85-sp80-sp60-sp30#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and connect the receiver: Switch on the SP85/SP80/SP60 and let it acquire satellites. Open your field software (Survey Pro or Spectra Geospatial Origin) and connect to the receiver over Bluetooth or cable. In Origin this is under menu > Connect / GNSS receiver setup; in Survey Pro you select the rover during survey start. 2. Decide how the rover reaches the internet: The SP85/SP80 have a built-in cellular modem and Wi-Fi so they can connect on their own (activated SIM or Wi-Fi). The SP60 typically has no internal cellular modem - connect it via the controller's SIM/Wi-Fi or a tethered phone. Note which path applies; you select it later as the internet source. 3. Origin: open the survey style and rover data link: In Origin tap the menu and choose Settings > Survey styles. Select your network-RTK style, tap Edit, select Rover data link, and set Type to 'Internet connection'. (In Survey Pro the equivalent comes when you start the GPS survey and pick the NTRIP rover - see step 8.) 4. Origin: create the GNSS correction source: Tap the context-menu button next to GNSS correction source and choose New. Set 'Use RTX (internet)' to No and 'Use NTRIP' to Yes. Leave 'Use NTRIP v1.0' off unless required. 5. Origin: enter the Premium Positioning caster: In IP Address enter rtkpremium.xyz and in IP port enter 2101. Either leave the mountpoint blank to pick it at survey start (recommended), or tick 'Connect directly to Mountpoint' and type COMMON. 6. Origin: enter YOUR NTRIP credentials: In NTRIP username and NTRIP password enter the personal login from your Premium Positioning welcome email - unique to your account. Leave TLS/proxy at defaults, then tap Store. 7. Origin: choose the internet source and store the style: Tap the context menu next to GNSS internet source and pick the path from step 2: 'Receiver internet - Wi-Fi' (or receiver SIM) for the SP85/SP80, or 'Controller internet' for the SP60. Tap Accept, then Store. 8. Survey Pro: start the GPS survey and pick the network rover: In Survey Pro start a job and begin the GPS survey. When prompted for the rover receiver type, choose the NTRIP / network rover option. Exact wording varies by version - match by function (an NTRIP-over-internet rover). 9. Survey Pro: define the caster (server/port): In Survey Pro's NTRIP/network server setup, add a server and enter Host/Server rtkpremium.xyz and Port 2101. Field labels ('Server', 'Address', 'IP', 'Port') differ by version - match by meaning. Save the server. 10. Survey Pro: enter credentials and load the source table: On the 'Select NTRIP Service' screen enter your own User Name and Password from the welcome email (optionally tick 'Save'). Tap Connect to log on and download the source table. 11. Select the COMMON mountpoint: From the source table / NTRIP service list, select COMMON. In Origin, if you left the mountpoint blank, the list appears at survey start - choose COMMON there. 12. Start receiving corrections: Confirm and start the survey. The receiver logs into rtkpremium.xyz:2101 with your credentials and streams COMMON. Watch the GNSS/RTK status: the data link goes active and the correction age counts in seconds (1 - 2 s). 13. Confirm a Fixed (RTK Fixed) solution: Wait for the solution to change from Autonomous/Float to Fixed. A low, stable correction age and cm-level precision indicate a healthy fix. Only measure once Fixed; if it stays Float, recheck internet, credentials, and that COMMON is selected. ### Steps for SP60 / SP30 with Survey Pro / FAST Survey / Origin 1. What you'll need: Your charged SP60 (or SP30), your controller running Survey Pro, FAST Survey, or Spectra Origin, and your personal NTRIP username/password from your welcome email. The SP60/SP30 normally has NO internal cellular modem, so the internet comes from the controller (its SIM or Wi-Fi) or a tethered phone - not the receiver. Have a working data connection on the controller before you start. 2. Power on and pair the receiver: Switch on the SP60/SP30 and the controller. In your field software, open the device/instrument connection screen and connect over Bluetooth (or serial). In Survey Pro this is the receiver/GNSS connection setup; in FAST Survey under Equip > GPS Rover (choose Spectra/Ashtech as manufacturer, SP60 as model); in Origin via Connections / receiver setup. Confirm the receiver shows connected. 3. Confirm internet on the controller: Because the SP60/SP30 has no built-in modem, make sure the CONTROLLER is online - its own SIM/cellular, a Wi-Fi network, or tethered to your phone's hotspot. The receiver pulls NTRIP corrections through this connection. (Label varies by app.) 4. Open the rover / network RTK configuration: In Origin: menu > Settings / Survey styles > select your RTK style > Edit > Rover data link. In Survey Pro: open the GNSS/receiver setup and configure a Network rover. In FAST Survey: under Equip > GPS Rover, open the RTK / Comms tab. Navigate to the equivalent 'rover data link / network RTK' settings in your app. 5. Set the data link to Internet / Network: Choose the internet/network option rather than a UHF radio or receiver-modem option. In Origin set Type to Internet connection. In Survey Pro choose Data Collector Internet / network connection. In FAST Survey set the Device to NTRIP (or 'Data Collector Internet'). 6. Select NTRIP as the protocol: Enable NTRIP. In Origin's GNSS correction source, set Use RTX (internet) to No and Use NTRIP to Yes (leave 'Use NTRIP v1.0' off unless needed). In FAST Survey / Survey Pro choose NTRIP as the correction/protocol type. 7. Enter the caster address and port: In the server/IP Address field enter rtkpremium.xyz and in the Port / IP port field enter 2101. (In Origin these are the 'IP Address' and 'IP port' fields.) The same for every customer. 8. Enter YOUR NTRIP username and password: In the NTRIP username and password fields, type the credentials from YOUR welcome email - unique to you; do not use anyone else's. 9. Load the source table and select the mountpoint: Fetch the source table - usually a button (arrow/refresh/'Get source table') beside the mountpoint field that connects and downloads the list. From the list select: COMMON. (In Origin you can set 'Connect directly to Mountpoint' to Yes and type COMMON to skip the prompt.) 10. Send NMEA/GGA if prompted: If your software shows an option to send your position to the caster ('Send NMEA GGA to base' or 'Send user identity info'), it's normally fine to leave it enabled - network/VRS streams use it to give you the nearest correction. (Optional; label varies by app.) 11. Save the configuration: Store/save the rover style or connection profile (in Origin tap Store) so you can reconnect later without re-entering the caster details. 12. Start the survey / connect to corrections: Start the RTK survey or measure/connect action. The controller connects to rtkpremium.xyz:2101, authenticates, requests COMMON, and streams corrections to the SP60/SP30. The data link goes active and correction age starts counting (a low, single-digit number of seconds is healthy). 13. Confirm a Fixed solution: Watch the solution status move Autonomous/Single → Float → Fixed ('RTK Fixed' or a green Fixed status) within seconds to a couple of minutes once corrections flow. Only measure once it reports FIXED. If it stays Float, re-check the controller's internet, the mountpoint (COMMON), your credentials, and that you have open sky. ### If the fix will not hold SP85/SP80 can reach the internet themselves (internal cellular + Wi-Fi); the SP60 generally has no internal cellular modem, so route internet through the controller or a tethered phone. The Origin field labels are grounded in the official Spectra Geospatial Origin help. Survey Pro's screen/field names vary by version (and older kit may run FAST Survey, whose menus differ again) - where a label can't be confirmed, match by function. The SP60/SP30 generally has no internal cellular modem - the internet for NTRIP comes from the controller (SIM/Wi-Fi) or a tethered phone; ensure the controller is online first. Field/menu names differ between Survey Pro, FAST Survey and Spectra Origin (and versions): the IP Address/IP port/Use NTRIP/Mountpoint names quoted are from Origin; in Survey Pro and FAST Survey navigate to the equivalent 'Network rover / NTRIP' settings (FAST Survey: Equip > GPS Rover). For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Spectra SP90m to the Premium Positioning correction network over NTRIP, using Survey Pro / Spectra Geospatial Origin. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-sp90m) to get your credentials. * Survey Pro / Spectra Geospatial Origin. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-sp90m#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and pair the SP90m: Switch on the SP90m and your data collector. In your field software (Origin, or Survey Pro / FAST Survey) connect to the receiver via Bluetooth or Wi-Fi as usual. Pairing screens vary by app/version - use your normal connect-to-receiver workflow. 2. Get the receiver online: The SP90m has an internal cellular modem and Wi-Fi. Insert an activated SIM (receiver or controller) and bring up cellular data, or join a Wi-Fi network with internet. In Origin this is the 'GNSS internet source'; in Survey Pro it's the internet/data-link connection. 3. Open the rover survey style / data link: Origin: menu > Settings / Survey styles > select your RTK style > Edit. Survey Pro / FAST Survey: open the GNSS rover / data link configuration. Match the equivalent 'network RTK rover' area in your software. 4. Set the data link to Internet: Origin: select Rover data link, set Type to 'Internet connection'. Survey Pro / FAST Survey: choose the internet/NTRIP data link type (often 'Network' or 'Internet'). 5. Open the NTRIP correction source: Origin: tap the context menu next to GNSS correction source, set Use RTX (internet) to No and Use NTRIP to Yes. Survey Pro / FAST Survey: choose NTRIP as the correction/network type. 6. Enter the caster host and port: Host / IP Address: rtkpremium.xyz - IP Port: 2101 - Protocol: NTRIP. In Origin these are the IP Address and IP port fields; in Survey Pro / FAST Survey the NTRIP server address and port. 7. Enter YOUR NTRIP username and password: In NTRIP username and NTRIP password, enter the credentials from your welcome email - unique to your account. Leave GGA/identity options at defaults unless told otherwise. 8. Save the connection and connect: Origin: Store the correction source, point the GNSS internet source at your live cellular/Wi-Fi connection, tap Accept, then Store the style. 9. Start the RTK survey: Origin: menu > Measure (choose your RTK style if prompted) > Measure points. Survey Pro / FAST Survey: start the survey / connect to the network. You'll see a 'Connecting to GNSS internet source' message. 10. Select the COMMON mountpoint: When the source table loads, select COMMON. (Origin can preset it: set 'Connect directly to Mountpoint' to Yes and enter COMMON to skip the prompt next time.) 11. Confirm corrections are streaming: The data-link icon appears on the status bar and incoming data shows. If it fails, re-check host/port/mountpoint and credentials, and that the receiver still has internet. 12. Wait for and verify a Fixed solution: With enough satellites and corrections, the SP90m initialises on-the-fly and the solution changes from Autonomous/Float to Fixed. Confirm the status reads Fixed (cm-level) before recording points. ### If the fix will not hold SP90m has an internal cellular modem and Wi-Fi, so corrections can run over a SIM or Wi-Fi. Field/menu names differ between Origin, Survey Pro and FAST Survey and between versions - this guide names Origin's labels precisely and describes the others generically; match the equivalent option. If it won't fix, confirm internet, the caster details, and credentials. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Stonex S3A / S5 II (GIS handheld) to the Premium Positioning correction network over NTRIP, using Cube-a. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=stonex-s3a-s5-ii) to get your credentials. * Cube-a. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=stonex-s3a-s5-ii#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Before you start: Have your welcome email open - it contains YOUR personal NTRIP username and password. The caster Host, Port and Mountpoint are the same for everyone (below). Make sure the handheld has working internet (mobile data or Wi-Fi) and a clear view of the sky. 2. Power on and open Cube-a: Switch on the Stonex receiver/handheld and open the Cube-a app (on some GIS units branded Stonex GIS Mobile; the layout is the same). 3. Connect to the receiver: Open the Device (or Communicate) menu and choose Connect. Set manufacturer to Stonex, connection type to Bluetooth, tap Search, pick your receiver's serial number and Connect. On an integrated GIS handheld the GNSS may already be connected - if so, skip ahead. 4. Open Working Mode: Go to the Device or Config menu and open Working Mode (some versions Tool > Working Mode). 5. Select Rover: Set the working mode to Rover (the unit that receives corrections; not a base). 6. Set the Data Link to internet: Choose the internet path: Phone Internet / Controller Internet / PDA Network (handheld/phone supplies the connection), or Receiver Network (receiver SIM/modem). Wording varies by Cube-a version - choose whichever routes corrections over the internet rather than UHF radio. 7. Choose NTRIP: Set the protocol / connection mode to NTRIP (sometimes shown as CORS). 8. Enter the caster Host and Port: Host (IP/Server/Address): rtkpremium.xyz · Port: 2101 · Protocol: NTRIP. Type the host exactly, no http\:// and no spaces. 9. Enter YOUR username and password: Enter the NTRIP User name and Password from your welcome email - unique to your account; do not use anyone else's. If you don't have them, contact support first. 10. Get the mountpoint list: Tap the button that downloads the available mountpoints - labelled Get access point, Retrieve Mountpoint, or similar by version. It needs internet and valid credentials to populate. 11. Select the COMMON mountpoint: From the access-point dropdown select COMMON. If it doesn't appear, double-check Host, Port and your credentials, then retrieve again. 12. Apply / Connect: Confirm with OK / Set, then Apply to start. Cube-a connects to the caster and receives corrections. If prompted to Send GGA / send NMEA, leave it enabled - the caster needs your approximate position. 13. Confirm a Fixed solution: On the survey screen watch Single/Autonomous → DGPS → Float → Fixed. Wait for FIXED (often green) before measuring - that's cm-level RTK. If it stays Float/Single, check internet, sky view, and that COMMON and your credentials are correct. ### If the fix will not hold Menu names differ across Cube-a versions and languages (Device vs Tool menu; Phone Internet vs Controller Internet vs PDA Network; 'Get access point' vs 'Retrieve Mountpoint'), so match the closest label. If corrections drop or the correction age climbs above \~5 s, your internet link is unstable - move to better coverage. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and wait for satellites: Switch on your Stonex receiver outdoors with a clear view of the sky and wait for it to track satellites. On the controller (Android phone or data collector), make sure mobile data or Wi-Fi is on if you'll route corrections through the phone, then open Cube-a. 2. Connect Cube-a to the receiver over Bluetooth: Go to Device > Communication. Set Device Type to 'Stonex GNSS' and Communication Mode to 'Bluetooth', tap 'Search', pick your receiver from the list (Bluetooth name usually matches the serial), and tap 'Connect' (tap 'pair' if prompted). (On some firmware you can use Wi-Fi: Communication Mode 'WIFI', connect to the receiver's hotspot.) 3. Open Rover working mode: Go to Device > Working Mode > Rover to open the 'Rover mode settings' screen - where you set the correction (data link) source. Leave Cut-off angle at its default unless told otherwise. 4. Choose the data link: In the 'Data Link' section, open the 'Communication Mode' dropdown. To use your phone's internet, choose 'Phone Network'. To use a SIM in the receiver, choose 'Internal Network'. Both send the same caster request; pick whichever has internet. (Wording varies by version - look for the network/internet option, not Radio or L-band.) 5. Set the connection protocol to NTRIP: Tap into the chosen data link to open its settings (Phone Network → the 'Bluetooth Data Link' screen; Internal Network → 'Rover network settings'). Under 'Connect Mode', select 'NTRIP'. 6. Enter the caster address and port: In 'CORS Settings', set the IP/host to rtkpremium.xyz and the Port to 2101. To save it, tap the '...' icon next to CORS Settings and add a custom entry (e.g. 'Premium Positioning'); otherwise type host and port directly. Protocol stays NTRIP. 7. Enter your own NTRIP username and password: In 'CORS Account', type the User and Password from your welcome email - unique to your account, case-sensitive. Do not share or guess; if you don't have them, contact support. 8. Load the mount point list from the caster: With host, port and credentials entered, fetch the available mount points (source table) - a 'Get access point' / 'Get mountpoint' button or the dropdown/refresh next to the MountPoint field. Cube-a connects and downloads the list. 9. Select the COMMON mount point: In the MountPoint field, select COMMON (type it in capitals if not shown) - the correction stream Premium Positioning provides. 10. Make sure GGA position is being sent: NTRIP casters need your approximate position. Ensure GGA upload is enabled - 'Internal Network' has a 'GGA Upload Interval(s)' value (default 5s is fine) and an 'Automatically connect to network' toggle. If no corrections arrive, check this first. 11. Apply and start the connection: Confirm the data link screen with 'OK' (or 'Start' on the Bluetooth Data Link screen), then on 'Rover mode settings' tap 'Apply' to switch the receiver into rover mode. Optionally tap 'Save to Configurations' first to reload these settings next time. 12. Confirm a Fixed solution: Watch the status progress Single/Autonomous → Float → Fixed. Verify the link under Device > Data Link Status ('Connected to server', signal level, GGA upload interval). Once Fixed (commonly green), you have cm-level RTK. If it stays Single/Float, recheck credentials, that MountPoint is COMMON, that the phone/SIM has internet, and that GGA sending is on. ### Steps for S900A / S850A / S700A with Cube-a (formerly SurvCE) 1. Power up with clear sky: Take the Stonex receiver (S900A / S850A / S700A) outside with an open view of the sky, away from buildings and trees. Power it on and give it a minute or two to start tracking satellites. 2. Open Cube-a and connect: Launch Cube-a, go to the Tool (or Config) menu and tap Connect. Choose your receiver model, set the connection to Bluetooth, search, select your receiver's serial number and pair. Confirm it shows Connected. (On older SurvCE: Equip → GPS Rover.) 3. Open Working Mode → Rover: From the Tool menu open Working Mode and choose Rover. This is where the data link and NTRIP settings live. 4. Set the Data Link: Set the Data Link. For a receiver without its own SIM, choose the option that routes corrections through the controller's internet - typically 'Phone Internet', 'Controller Network' or 'PDA Network'. If the receiver has a built-in 4G modem and SIM, choose 'Receiver Network' (Internal GSM) and enter the APN. 5. Choose NTRIP protocol: Set the protocol / connection type to NTRIP (sometimes 'NTRIP Client', or Connection Mode = NTRIP) so Cube-a pulls RTCM corrections from an internet caster rather than a radio. 6. Add the caster (server + port): Create or edit an NTRIP connection profile and enter Server / Host / IP: rtkpremium.xyz and Port: 2101. If the field expects an IP, you can still type the domain rtkpremium.xyz - Cube-a resolves it. 7. Enter YOUR NTRIP credentials: In User Name and Password type the personal NTRIP login from your Premium Positioning welcome email - unique to your account. The caster requires authentication. 8. Retrieve the source table: Tap the control that fetches mountpoints - usually 'Get Source Table', 'Source Table', 'Get Access Point', or a refresh/list icon next to the mountpoint field. Cube-a downloads the list of available streams. 9. Select mountpoint COMMON: From the source table / Access Point list select COMMON. If the list doesn't populate, type COMMON manually (capitals) and double-check the host, port and credentials. 10. Enable position upload (GGA): Make sure 'Send GGA' / 'Send NMEA' is enabled - a network/VRS caster needs your approximate position to send the correct corrections. Most Cube-a versions enable this automatically for NTRIP. 11. Apply and confirm connection: Tap OK / Apply / Connect to save and start the data link. Cube-a shows the NTRIP connection active and a rising count of received correction bytes. If it fails, recheck server, port, mountpoint and credentials. 12. Verify a Fixed solution: Return to the Survey screen and watch the status progress Single (Autonomous) → Float → Fixed, typically within seconds to a minute or two. Confirm it reads Fixed and the latency/age stays low (a few seconds) before surveying. ### If the fix will not hold Corrections can run through the receiver's SIM ('Internal Network') or the phone's connection ('Phone Network') - choose whichever has internet. Menu/button names vary slightly between Cube-a versions and models (S700A/S800A/S980A) - match the equivalent option. Steps based on the Stonex Cube-a 4.0 field software manual. On older SurvCE the path is Equip → GPS Rover → RTK tab, with the data-link device set to the data collector's internet and the network type set to NTRIP; the caster host, port, credentials and COMMON mountpoint are entered the same way. If you don't reach Fixed: confirm internet on the controller/SIM, re-fetch the source table, and verify host/port/mountpoint.

These steps connect a Tersus Oscar / Luka / David to the Premium Positioning correction network over NTRIP, using Nuwa app (Android). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=tersus-oscar-luka-david) to get your credentials. * Nuwa app (Android). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=tersus-oscar-luka-david#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Charge and power on the receiver: Make sure your Tersus Oscar (or David) is charged and powered on. On your Android device, install and open the Tersus Survey "Nuwa" app, and enable Bluetooth and mobile data. 2. Connect the receiver over Bluetooth: In Nuwa tap \[Device] > \[Connect]. Set the device type to your model (Oscar or David), choose Bluetooth, tap the search icon and select your receiver's Bluetooth address. Tap \[Connect] and wait for connected status. The antenna model is selected automatically. 3. Open the Rover work mode: Tap \[Device] > \[Rover] (in some versions under \[Config] or \[Survey]) to open the Work Mode list. Tap \[New]/\[Add] for a fresh rover profile, or open an existing one to edit. 4. Set the Datalink to the phone's internet: Set the Datalink used to receive corrections. To use the phone's mobile data choose \[PhoneNetwork] / \[PDA Network] (label differs by version). To use the receiver's own SIM choose \[Receiver Network]. Don't choose Internal Radio for NTRIP. 5. Choose the NTRIP protocol: Set the data-link Protocol to \[NTRIP] (Nuwa also offers TCP and TCS, but our service uses NTRIP). 6. Enter the caster address and port: IP / Address / Domain: rtkpremium.xyz. Port: 2101. Leave protocol NTRIP. These caster details are the same for every customer. 7. Enter your personal NTRIP username and password: In User and Password type YOUR OWN NTRIP credentials from your Premium Positioning welcome email - unique to your account. If you can't find them, contact support. 8. Retrieve the source table and select the mountpoint: Tap the refresh icon (or \[Get] / source-table button) next to Mount Point. Nuwa downloads the available mountpoints. Select COMMON. If empty, re-check the address, port, username/password and that the phone has internet. 9. Save and apply the configuration: Tap \[OK]/\[Confirm]/\[Save] to store the config and return to the Work Mode list. Select (tick) this configuration to make it active - Nuwa starts the rover and connects to the NTRIP service. 10. Confirm the NTRIP connection is live: The app shows the rover connecting and receiving correction data; a data/connection indicator shows activity once the mountpoint is streaming. 11. Watch the solution status climb to Fixed: Go to the \[Survey] screen. The status progresses Single → Float → Fixed. Possible states are Single, DGPS, Float and Fixed. 12. Verify Fixed before you measure: Only record points once it reads Fixed with cm-level HRMS/VRMS. If it stays Float/Single, confirm open sky, good mobile signal, the COMMON mountpoint, and correct credentials. ### If the fix will not hold Nuwa names vary by version (rover setup may be under Device, Config or Survey; the mobile-data datalink is 'PhoneNetwork' in newer builds and 'PDA Network' in older; 'Get source table' may be a refresh icon next to Mount Point). For NTRIP over the phone use PhoneNetwork/PDA Network; use Receiver Network only if the receiver has its own SIM. Fixed needs clear sky and a stable internet connection. Menu/field names differ slightly between Nuwa versions and between Luka and David - match the closest equivalent (the network data-link option that uses your phone's internet, and the 'NTRIP' protocol). If you can't reach Fixed, check Host/Port/credentials, mobile data, re-fetch the source table, and confirm COMMON is selected. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

Choose a Network RTK configuration: Name the configuration and set Type to Network RTK (the rover-over-internet mode used for a caster). 4. Set the Rover Receiver options: On the Rover Receiver tab select Receiver Model (GR-5 or HiPer SR), set Protocol to NTRIP, and set the Antenna to match. Set Antenna Height to your actual pole height. 5. Set the data link to the controller modem: On the Rover Modem tab set Modem / Connect to Controller, so MAGNET uses the controller's own internet (Wi-Fi or SIM) rather than a radio. Make sure the controller has working internet. 6. Enter the caster host and port: In the network/internet settings enter Host: rtkpremium.xyz and Port: 2101. Confirm Protocol is NTRIP. 7. Enter YOUR NTRIP username and password: Enter the NTRIP user name and password from your Premium Positioning welcome email - unique to your account; do not use example values or leave blank. 8. Save and start the survey: Save the configuration, then select it as the active Survey configuration. Go to Survey / Topo to begin and trigger the caster connection. 9. Load the source table (mount point list): On connect, MAGNET requests the source table. If it doesn't load automatically, tap the mount-point drop-down (a 'no mount point to connect to automatically' prompt may appear) to fetch the list. 10. Select the COMMON mount point: From the source table choose COMMON (sort by Mountpoint/Format/Distance to find it) and confirm. 11. Connect to the caster: Tap Connect. MAGNET logs in with your credentials and streams corrections - look for a 'Data received' indicator. 12. Confirm a Fixed solution: Watch the solution status move Autonomous/Standalone → Float → Fixed (usually under a minute with good sky). Only record/stake once Fixed. If it stays Float, re-check internet, the COMMON mount point, and your credentials. ### If the fix will not hold The controller needs working internet (Wi-Fi or SIM) because Modem Connect is set to Controller. Menu wording differs slightly between MAGNET Field versions (GPS+ Configuration vs GNSS/Survey configuration, Rover Modem vs Rover Internet) - match the closest equivalent. Same MAGNET Field workflow as Topcon HiPer VR and Sokkia.

Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r1-r2) to get your credentials. * Trimble Mobile Manager (Android/iOS) + a GIS app. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r1-r2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Install Trimble Mobile Manager: On Android or iOS, install Trimble Mobile Manager (TMM) and open it. TMM is the free utility that configures the R1/R2 and feeds your position to your GIS app. Sign in if prompted. 2. Power on and pair the receiver over Bluetooth: Hold the receiver's power button until the LED blinks. In the OS Bluetooth settings, pair the receiver (it appears by model/serial, sometimes 'GNSS'). If a PIN is requested, the Trimble default is 0000 unless changed. 3. Select the receiver as the position source in TMM: In TMM open the Position source (GNSS receiver) setting, set type to Bluetooth, list connected/nearby devices, and select your R1/R2. Wait for connected status. Wording varies slightly by version. 4. R2 only: confirm a correction-capable option is active: The R2 needs an RTK Rover (real-time corrections) option/subscription enabled for cm RTK from an NTRIP caster. If you only see SBAS/autonomous accuracy, the option may not be active - contact Premium Positioning or your dealer. 5. Open Configuration: Tap the Configuration (gear) icon and select Configuration to reach the correction settings. 6. Set the correction source to Custom local: Tap GNSS correction source and select 'Custom local' - the option for a third-party NTRIP caster. 7. Choose the NTRIP protocol: For Protocol select 'NTRIP' (not Direct). 8. Enter the caster server and port: Server/URL: rtkpremium.xyz, Port: 2101 - the same for every Premium Positioning customer. 9. Enter YOUR NTRIP username and password: Set the corrections account username/password to the personal credentials from your welcome email - unique to you; do not use anyone else's. 10. Select the COMMON mount point: TMM connects and downloads the mount point table. Select COMMON. If the list doesn't load, re-check server, port and credentials. 11. Set the reference frame: Select the GNSS source reference frame; if unsure choose 'Auto'. Set a custom epoch only if advised. 12. Share TMM's position with your GIS app: Android: in TMM Application settings turn on 'Share location', then in Developer options set 'Select mock location app' to Trimble Mobile Manager and disable battery optimisation for TMM. iOS: TMM feeds the system location automatically - in your GIS app set the location source to the system/Trimble location. Confirm the GIS app reads the external receiver. 13. Confirm RTK Fixed: Watch TMM (and the GIS app's accuracy): with corrections flowing it should reach 'RTK Fixed' at cm-level. If stuck on Float, leave it in open sky; if it never fixes, recheck COMMON, credentials, and sky view. ### If the fix will not hold The R2 needs an active RTK Rover/correction option for cm RTK. Some TMM labels differ between versions and between Android and iOS (position source / GNSS receiver, GNSS correction source, Share location) - match the equivalent option. Internet (mobile data or Wi-Fi) is required for the NTRIP stream. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Trimble R12 / R10 (TSC7 / TSC5) Connect a Trimble R12 or R10 with a TSC7 or TSC5 to RTK Premium corrections over NTRIP using Trimble Access: caster settings and the steps to a fixed solution. These steps connect a Trimble R12 / R10 (TSC7 / TSC5) to the Premium Positioning correction network over NTRIP, using Trimble Access. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r12-r10-tsc7-tsc5) to get your credentials. * Trimble Access. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r12-r10-tsc7-tsc5#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Switch on your R12 (or R10 / R8s) and the TSC7 / TSC5 controller. Trimble Access connects to the receiver over Bluetooth or cable; the corrections travel over the controller's own internet (its Wi-Fi or SIM). Make sure the controller has working internet before heading out. 2. Open or create your RTK survey style: From the main menu tap Settings > Survey styles. Reuse the built-in 'RTK' style or tap New to create one of type RTK, select it and tap Edit. (On older builds this lives under Configuration / Survey styles.) 3. Set the rover data link to Internet connection: Open Rover data link and set the Type field to 'Internet connection'. This tells the rover to receive RTK corrections over NTRIP rather than via a radio. 4. Open the GNSS correction source: Tap the context menu (small arrow) next to the correction-source field to open the GNSS correction source tab, then tap New. On Trimble Access 2021-era builds the equivalent is a 'GNSS contact' under Settings / Connections / GNSS contacts - it is the same thing. 5. Turn on NTRIP: Set the 'Use NTRIP' switch to Yes. Leave 'Use NTRIP v1.0' off unless the connection fails and you need to force the older protocol. 6. Enter the caster address and port: In the IP Address (server / host) field enter rtkpremium.xyz and in the IP port field enter 2101. Do not add 'http\://' or a trailing slash - just the host name and the port. 7. Enter the mountpoint: Set 'Connect directly to Mountpoint' to Yes and enter COMMON (in capitals). Alternatively leave it off and pick COMMON from the caster's source table when you start the survey. 8. Enter YOUR NTRIP username and password: In the NTRIP username and NTRIP password fields, type the unique credentials from YOUR Premium Positioning welcome email. They are typed into the device only and are never sent to the Premium Positioning website. 9. Save the correction source: Leave proxy and TLS options off unless your IT team told you otherwise, then tap Accept / Store to save the correction source. 10. Choose the internet path and store the style: Back in Rover data link, use the context menu next to 'GNSS internet source' and select where the internet comes from - normally 'Controller internet' (the TSC7/TSC5's Wi-Fi or SIM). Tap Accept, then Store to save the style. 11. Start the survey: Open or create your job, tap the menu and choose Measure, and select this RTK style if prompted. You'll see 'Connecting to GNSS internet source', then the internet-source icon appears in the status bar. 12. Select the mountpoint if prompted: If you didn't tick 'Connect directly to Mountpoint', the source table appears - select COMMON. If you set it to connect directly, it connects to COMMON automatically. 13. Confirm RTK: Fixed: The survey initialises once enough satellites are tracked. Confirm the status bar shows 'RTK: Fixed' (centimetre-level) before measuring. If it stays 'RTK: Float' for more than a minute or two, see the notes below. ### If the fix will not hold Tips: (1) The controller must have live internet (Wi-Fi or SIM) - without it there is no NTRIP connection. (2) If it won't connect, check the host has no typos and no 'http\://', the port is 2101, and the mountpoint is COMMON in capitals. (3) An empty source table or login error almost always means a wrong username/password - re-enter carefully from the welcome email. (4) If it only connects with 'Use NTRIP v1.0' ticked, leave that on. (5) Sitting on 'RTK: Float' usually means weak mobile signal, too few satellites, or overhead obstruction - move to clearer sky. Exact wording differs between Access versions; 'GNSS contact' and 'GNSS correction source' are the same thing.

These steps connect a Trimble R12i to the Premium Positioning correction network over NTRIP, using Trimble Access. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r12i) to get your credentials. * Trimble Access. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r12i#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and connect the receiver: Mount the R12i on your pole, power it on, and pair it to the controller (TSC7/TSC5) over Bluetooth or cable. Confirm it's connected in Trimble Access. Make sure the controller has working internet (SIM data or Wi-Fi), as corrections are delivered over the internet. 2. Open the survey style settings: From the main menu, go to Settings > Survey styles, select the RTK style you use for internet corrections, then tap Edit. If you don't have a suitable style, create a new one of type RTK. (Wording varies slightly by version - match the closest equivalent.) 3. Configure the rover data link as an internet connection: In the survey style, open Rover data link and set the Type field to Internet connection - so corrections come over the internet rather than a radio. 4. Set the GNSS internet source to Controller internet: Open the GNSS internet source option and select Controller internet so the controller's own SIM/Wi-Fi carries the corrections. (Receiver internet also exists; Controller internet is simplest for most setups.) 5. Open the GNSS correction source and enable NTRIP: Open the GNSS correction source for the rover and set Use NTRIP to Yes. Leave Use NTRIP v1.0 unticked unless you have a specific reason to use v1.0. 6. Enter the caster address and port: In the IP Address field enter rtkpremium.xyz and in the IP Port field enter 2101 - the same for every customer. 7. Enter your NTRIP username and password: In the NTRIP username and password fields, enter YOUR OWN credentials from your welcome email - unique to your account; Premium Positioning will never provide them inside the device. If you can't find them, contact support. 8. Select the COMMON mountpoint: Set the mountpoint to COMMON - type it directly (e.g. via 'Connect directly to Mountpoint') or, if the style prompts you at survey start, pick COMMON from the source table the caster returns. 9. Save the survey style: Tap Store (or Accept/Save, by version) to save your changes so you don't re-enter the caster details next time. 10. Start the survey: From the main menu choose Measure (or Measure points), then select this RTK internet style. Trimble Access establishes the internet connection - you may briefly see 'Connecting to GNSS internet source'. If prompted, confirm the correction source and COMMON mountpoint. 11. Confirm the corrections link is live: On success, the GNSS internet source icon appears in the status bar, confirming correction data is streaming. If it fails, recheck host, port, mountpoint, and your username/password. 12. Align the IMU for tilt compensation: The R12i has IMU tilt compensation - align the IMU when prompted, typically by walking a few metres and/or gently rotating the pole as the on-screen guidance indicates. Alignment usually completes in a few seconds and re-aligns automatically during normal movement, letting you measure tilted without levelling the bubble. 13. Confirm RTK:Fixed before measuring: Wait for the solution status to show RTK:Fixed (cm-level). Only store points once you have RTK:Fixed and, for tilted measurements, a valid IMU alignment. If it stays Float, give it time with clear sky or re-check the correction connection. ### If the fix will not hold The COMMON mountpoint is a network (VRS-style) source, so you need clear sky and a working data connection for a Fixed solution. Menu/button names differ slightly across Trimble Access versions and between TSC7 and TSC5 - match the closest equivalent. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Trimble R8s / R6 Connect a Trimble R8s or R6 to RTK Premium corrections over NTRIP using Trimble Access: caster settings and the steps to a fixed solution. These steps connect a Trimble R8s / R6 to the Premium Positioning correction network over NTRIP, using Trimble Access. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r8s-r6) to get your credentials. * Trimble Access. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r8s-r6#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get the controller online and connected to the receiver: On your TSC7/TSC5, make sure Trimble Access has working internet (controller SIM, Wi-Fi hotspot, or tethered phone). Power on the R8s / R6 and confirm the controller is paired/connected (Bluetooth or cable). Corrections come over the controller's internet, so a stable data connection is essential. 2. Open the RTK survey style for editing: From the main menu tap Settings, then Survey styles. Select your RTK style (or create one based on RTK) and tap Edit. 3. Set the rover data link to an internet connection: Open Rover data link and set Type to Internet connection (older versions: 'Internet rover'). This takes corrections over the controller's internet rather than a radio. 4. Open the GNSS correction source: On Rover data link, tap the button/arrow next to GNSS correction source. Select an existing source or tap New to create one - where the caster (NTRIP) details are entered. 5. Turn on NTRIP: In the correction source, set Use NTRIP to Yes. Leave Use RTX (internet) set to No. If 'Use NTRIP v1.0' is shown, leave it unticked unless told otherwise. 6. Enter the caster address and port: In IP Address enter rtkpremium.xyz and in IP port enter 2101 (fixed for all customers). On some versions the field is 'Server'/'Address' - use the host/port fields for the caster. 7. Enter YOUR NTRIP username and password: In the NTRIP username and NTRIP password fields, enter the credentials from your welcome email - unique to your account; do not use anyone else's. 8. Set the mountpoint to COMMON: In Mountpoint name enter COMMON. To be prompted at survey start instead, leave it blank and pick COMMON from the source list later. If your version has a 'Connect directly to Mountpoint' switch, set it to Yes to skip the prompt. 9. Choose the internet source and save: Set the GNSS internet source field to Controller internet. Tap Accept to save the correction source, then Accept / Store to save the style. The save button wording (Accept/Store/Save) varies slightly by version. 10. Start the RTK survey: From the main menu tap Measure (or Stakeout), select your RTK style if asked, then choose e.g. Measure points. If the style is set to prompt, select the correction source you created. 11. Confirm the mountpoint and let it connect: If prompted for a mountpoint, select COMMON. Trimble Access shows 'Connecting to GNSS internet source' and the GNSS internet source icon appears in the status bar once connected. 12. Wait for a fixed solution (RTK:Fixed): With corrections flowing and enough satellites, the rover initialises on-the-fly. Watch the status line until it reports RTK:Fixed (cm-accurate), then start measuring. If it stays Float, check sky view, internet signal, and that the mountpoint/credentials are correct. ### If the fix will not hold Menu/field names follow recent Trimble Access on the TSC7/TSC5; on older versions some labels differ slightly (the data link 'Type', the final save button) - match by meaning. Same workflow as other Trimble Access receivers. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Trimble R980 / R780 Connect a Trimble R980 or R780 to RTK Premium corrections over NTRIP using Trimble Access: caster settings and the steps to a fixed solution. These steps connect a Trimble R980 / R780 to the Premium Positioning correction network over NTRIP, using Trimble Access. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r980-r780) to get your credentials. * Trimble Access. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-r980-r780#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Pair receiver and get the controller online: Power on the R980/R780 and your controller (TSC7, TSC5 or TDC600). In Trimble Access, connect to the receiver over Bluetooth via Instrument > Bluetooth. Make sure the controller itself has internet - its own SIM/Wi-Fi, or routed through the receiver's modem/Wi-Fi. Corrections come over the internet (NTRIP), so a live data connection is required. 2. Open your RTK survey style: From the main menu tap Settings > Survey styles. Choose your RTK style (or copy an existing one to a new name) and tap Edit. 3. Set the rover data link to Internet connection: Select Rover data link and set the Type field to Internet connection. This receives corrections over the internet rather than a radio. 4. Create the GNSS correction source: Next to the correction source field (labelled GNSS correction source on recent versions; GNSS contact on older ones - same workflow), tap the context menu and choose New. 5. Enable NTRIP: Set Use RTX (internet) to No, then Use NTRIP to Yes. Leave Use NTRIP v1.0 off unless you have a connection problem and need to fall back. 6. Enter the caster server and port: In IP Address enter rtkpremium.xyz and in IP port enter 2101. Leave Use proxy server off unless your IT network requires a proxy. 7. Enter YOUR NTRIP username and password: In the NTRIP username and NTRIP password fields, enter the personal credentials from your Premium Positioning welcome email - unique to your account; do not use anyone else's. 8. Set the mountpoint to COMMON: Turn on Connect directly to Mountpoint and type COMMON (exactly, capitals). Or leave it off and pick COMMON from the live mountpoint table when you start the survey. 9. Choose how the controller reaches the internet: Next to the GNSS internet source field, open the context menu and select Controller internet, Receiver internet - modem, or Receiver internet - Wi-Fi, depending on how you got online. Tap Accept. 10. Save the survey style: Tap Accept on Rover data link, then Store (or Accept) to save the style. Your NTRIP profile is now reusable. 11. Start the RTK internet survey: Open your job, tap Measure (or Stakeout) and select this RTK style. You'll briefly see Connecting to GNSS internet source. 12. Confirm the mountpoint and corrections: If you didn't pre-set the mountpoint, the source table appears - select COMMON. The GNSS internet source icon then appears in the status bar. 13. Wait for an RTK:Fixed solution: Let it initialise on-the-fly. The status reads RTK: Float at first, then RTK: Fixed with small H:/V: precision once ambiguities resolve. On an R980/R780 with IMU, complete the tilt alignment when prompted. Don't measure until RTK: Fixed. ### If the fix will not hold Labels vary slightly by Trimble Access version (newer 'GNSS correction source' / 'GNSS internet source' vs older 'GNSS contact'); the path is the same. If it won't connect, recheck rtkpremium.xyz / 2101 / COMMON, confirm the controller has live internet, and verify your credentials. If it stays RTK: Float, give it open sky and time.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on and get online: Charge and power on the G970 II. On your Android controller/phone, connect to mobile data or Wi-Fi and confirm internet. The phone provides the internet link that carries the corrections; no SIM is needed in the receiver. 2. Open the field app: Launch the Unistrong field app (eGPS / UFO, or the SurvX/EGStar-style app supplied with the unit). Open/create a job if prompted. 3. Connect to the receiver via Bluetooth: Go to the Device (or Connect/Communication) menu. Set Device Type to your Unistrong receiver, connection Bluetooth, tap Search, select your G970 II by serial number, Connect. Wait for connected. Labels vary slightly by version. 4. Set the receiver to Rover: In Device open Rover (or Work Mode > Rover) so the receiver receives corrections. Confirm Rover mode before continuing. 5. Set the Data Link to the phone's internet: Set Data Link to the network/internet option - 'Phone Internet', 'Network', 'Phone(Internet)' or 'Controller Internet' - routing corrections over your phone's data rather than a radio/modem. 6. Choose the NTRIP / CORS protocol: Set the Protocol (Server type) to NTRIP (some versions label it CORS - same internet-correction protocol). 7. Enter the caster host and port: Host (IP/Address): rtkpremium.xyz and Port: 2101. Leave any 'use TLS/proxy' options off unless told otherwise. 8. Enter YOUR NTRIP username and password: Enter the NTRIP username/password from YOUR welcome email - unique to your account; don't use anyone else's or leave blank. Contact Premium Positioning if you can't find your welcome email. 9. Get the source table: Tap 'Get Source Table' (or 'Get Access Point' / 'Get Mountpoint' / the refresh icon). The app connects and downloads the mountpoints. 10. Select mountpoint COMMON: From the source-table list select COMMON. If it doesn't appear, re-check host, port and credentials, then fetch again. 11. Apply and connect: Tap Apply / OK / Connect to start the NTRIP connection and stream corrections to the receiver. 12. Confirm a Fixed solution: Watch the status bar move Single → Float → Fixed (RTK Fixed), usually 10 - 60 s outdoors with clear sky. 'Fixed' confirms cm RTK. If it stays Single/Float, check internet signal, sky view, and that COMMON and your credentials are correct. ### If the fix will not hold The G970 II ships with a SurvX/EGStar-family Android app (branded eGPS or UFO); menu/button names follow that standard flow but exact wording can vary by app/firmware version - look for the equivalent option. A clear, open-sky view and stable mobile data are needed to reach Fixed.

These steps connect a Bad Elf Flex / Flex Mini to the Premium Positioning correction network over NTRIP, using Bad Elf GNSS Master app (+ a GIS app). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=bad-elf-flex-flex-mini) to get your credentials. * Bad Elf GNSS Master app (+ a GIS app). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=bad-elf-flex-flex-mini#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power on the Flex: Hold the power button until the Bad Elf Flex / Flex Mini powers up. Give it a clear view of the sky and, for best accuracy, mount it on a survey pole \~1 m or more above the ground to reduce multipath. 2. Pair over Bluetooth in OS settings first: Before opening any app, pair at the OS level: Settings > Bluetooth, pair the device named like 'Bad Elf Flex \[serial]', wait for 'Connected'. Pairing in the OS first is the most common fix for connection problems on iOS and Android. 3. Open the Bad Elf app: Launch the Bad Elf controller app (e.g. Bad Elf / GNSS Master). Select your connected Flex from the device list. App name/icons vary by version. 4. Open the corrections / NTRIP section: In the receiver settings find the corrections area ('Correction Mode', 'Corrections', or 'RTK Corrections') and choose NTRIP / 'RTK via NTRIP' > Network. (In GNSS Master this is the 'Corrections' page with Mode = 'NTRIP Client'.) Labels differ slightly by version. 5. Create a new NTRIP profile: Tap '+' to add a new NTRIP profile and name it e.g. 'Premium Positioning'. 6. Enter the caster host and port: Host: rtkpremium.xyz Port: 2101 Protocol: NTRIP. Double-check the host spelling. 7. Enter the mount point: Set the Mount point to COMMON (capitals). If the app offers a fetch-source-table button you can confirm COMMON is listed, but typing it manually is fine. 8. Enter YOUR NTRIP username and password: Enter the NTRIP username/password from your welcome email - unique to you. Don't use your website/portal login, and don't share them. If you can't find them, contact support. 9. Enable Send GGA: Turn on 'Send GGA' / 'Send NMEA GGA to base station' - the network is VRS-style and needs your approximate position to start streaming. Leave NTRIP version at the default unless told otherwise. 10. Save and connect: Save (or Done) to store the profile, select it, and tap Connect. The app logs in and feeds corrections to the Flex automatically. 11. Confirm RTK Fixed: Watch the solution status move Autonomous → DGPS/Float → 'RTK Fix' (\~1 - 2 cm). Wait for 'RTK Fix' before recording points - 'Float' is not yet survey-grade. 12. Set the Flex as your GIS app's location source: iOS: the Flex feeds Location Services automatically once connected - just keep the Bad Elf app connected and your GIS app uses the device location. Android: enable the receiver as the mock/location provider (turn on 'Mock location' after selecting the Bad Elf app in Developer Options), or use a direct app link (e.g. SW Maps) if your GIS app supports it. Confirm the GIS app reports cm accuracy. ### If the fix will not hold Always pair over Bluetooth in OS settings before opening the app. Menu/button names differ between Bad Elf app versions and iOS vs Android - match the closest label. Keep a clear sky view and pole-mount the antenna. If you stay on Float, recheck the host spelling, that Send GGA is on, the mount point is exactly COMMON, and your credentials.

Charge and power on the Arrow: Power on your Arrow Gold (or Arrow 100/200) with a clear view of the sky. Have your GIS app (e.g. ArcGIS Field Maps) and Eos Tools Pro installed on the same phone/tablet. 2. Pair the Arrow over Bluetooth: iOS: pair the Arrow in system Settings > Bluetooth before opening Eos Tools Pro. Android: connect from within Eos Tools Pro (Android also needs Developer Options > mock location set to Eos Tools Pro, with 'Replace Device Location' enabled). Wait for connected status. 3. Confirm a raw GNSS position: Open Eos Tools Pro > Status menu > Position tab. Confirm coordinates are populated (autonomous/GPS solution) before adding corrections. 4. Open the NTRIP correction settings: Tap the Differential menu and select the NTRIP tab. Wording varies slightly by version/platform - look for the NTRIP / corrections section. 5. Set the protocol: Set Protocol to NTRIP (standard HTTP). Only use HTTPS if your provider tells you to. 6. Enter the caster address and port: IP Address / Server: rtkpremium.xyz Port: 2101 - the same for every Premium Positioning customer. 7. Enter your NTRIP credentials: Tap the Credentials field and enter YOUR OWN NTRIP username and password exactly as in your welcome email (case-sensitive); do not use anyone else's. Tap Done. 8. Retrieve the source table: Tap the Mountpoint field so Eos Tools Pro queries the caster and loads the source table. If it won't load, double-check host, port and credentials and confirm internet; you can also open rtkpremium.xyz:2101 in a browser to verify the source table downloads. 9. Select the COMMON mountpoint: From the list select COMMON - correct for all Premium Positioning customers. Tap Done. 10. Start streaming corrections: Tap Start Streaming. The Arrow begins receiving corrections (the green Tx LED blinks). You can enable Auto-start streaming and Save as New Profile for next time. 11. Confirm a Fixed RTK solution: Return to Status > Position and watch Autonomous → Float → Fixed (Android shows Diff Status = RTK Fixed). When Fixed, HRMS drops to a few cm, Diff Age settles \~1 - 2 s, and a Diff Station ID appears. 12. Use it in your GIS app: With Eos Tools Pro streaming in the background, open ArcGIS Field Maps (or your GIS app) and confirm it uses the Arrow's high-accuracy location. Keep Eos Tools Pro running while collecting. ### Eos Tools Pro settings * Turn on Send GGA: Enable send GGA so the network receives your approximate position. ### If the fix will not hold Menu/field names (Differential / NTRIP / Mountpoint / Credentials / Start Streaming) differ slightly between iOS and Android and app versions; choose the closest match. A Fixed solution needs clear sky and internet. If it won't fix, recheck host/port/COMMON and credentials, then stop and restart streaming.

These steps connect a Geneq SXBlue III / Platinum to the Premium Positioning correction network over NTRIP, using SXBlue app / SXBlue Toolbox (+ a GIS app). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geneq-sxblue-iii-platinum) to get your credentials. * SXBlue app / SXBlue Toolbox (+ a GIS app). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=geneq-sxblue-iii-platinum#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Install the SXblue Toolbox app: Install Geneq's SXblue Toolbox from Google Play (Android) or the App Store (iOS). It acts as the NTRIP client and feeds corrected positions to your GIS app. Some older iOS setups use iSXblue / iSXBlue RTN - the NTRIP fields are the same, screen names may differ. 2. Power on and pair the receiver over Bluetooth: Switch on the SXblue receiver and let it acquire satellites. In Settings > Bluetooth pair the unit; if a PIN is requested for SXblue I/II/III/i/Platinum it is 12345678. You only pair once. 3. Connect the Toolbox app to the receiver: Open SXblue Toolbox and select your paired receiver as the active/running receiver (Android: top-right selector). Confirm live data (position, sky plot) appears - the app is talking to the SXblue, not the phone GPS. 4. Open the correction / differential source settings: Go to receiver configuration/settings and find the differential correction source. Choose the internet / NTRIP source (may be labelled NTRIP, DIP, or 'RTK over internet'). 5. Open the NTRIP client / login credentials list: In the NTRIP (or DIP) client section, add a new NTRIP profile/entry. Saving a named profile lets you reconnect later without re-typing. 6. Enter the caster server and port: Server / Caster / Host: rtkpremium.xyz, Port: 2101. Use NTRIP (v1 if asked). No http\:// - just the hostname. 7. Enter your NTRIP username and password: Enter the NTRIP Username and Password from your welcome email exactly (case-sensitive) - unique to your account; do not share. If you can't find them, contact Premium Positioning. 8. Load the source table and select the mountpoint: Save/connect so the app retrieves the source table, then select COMMON. If you can type it directly, enter COMMON exactly (capitals). 9. Connect to the caster: Confirm/connect to start streaming. The app reports it is connected and receiving correction data. If rejected, re-check username/password and that the mountpoint is COMMON. 10. (Android only) Set the app as the mock location provider: To feed a separate GIS app on Android: enable Developer options, turn on mock locations / 'Select mock location app', and choose SXblue Toolbox. iOS does not need this - GIS apps read the SXblue position via the standard location feed. 11. Point your GIS app at the SXblue position: Open your GIS / field app and confirm it is using the external SXblue receiver / mock location rather than the built-in GPS (some apps have their own location-provider setting). 12. Confirm a fixed RTK (cm) solution: In SXblue Toolbox watch the quality status. FIX means ambiguities are resolved and you are at cm accuracy (\~1 - 2 cm). Only collect once Fixed; if it stays float/DGPS, move to open sky and re-check the caster connection. ### If the fix will not hold A live internet connection (mobile data/Wi-Fi) is required. Menu/screen names differ between SXblue Toolbox versions, iOS vs Android, and older apps such as iSXblue RTN - match the closest equivalent (NTRIP/DIP client, differential source, mountpoint/source table). Clear sky speeds up getting and holding a fixed solution. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Juniper Geode GNS3 / GNS2 Connect a Juniper Geode GNS3 or GNS2 to RTK Premium corrections over NTRIP using Geode Connect: caster settings and the steps to a fixed solution. These steps connect a Juniper Geode GNS3 / GNS2 to the Premium Positioning correction network over NTRIP, using Geode Connect (+ a GIS app). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=juniper-geode-gns3-gns2) to get your credentials. * Geode Connect (+ a GIS app). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=juniper-geode-gns3-gns2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Check RTK is supported: NTRIP/RTK requires a Geode model and subscription that supports RTK (e.g. the GNS3 RTK model). A sub-metre-only Geode will connect to NTRIP but may not reach cm RTK Fixed. Check the label on the receiver's base or ask Premium Positioning if unsure. 2. Install Geode Connect: Install the free Geode Connect app (Google Play / App Store). It holds the NTRIP settings and must stay open while collecting - if it closes, corrections stop. You also need live cellular data throughout. 3. Power on and pair over Bluetooth: Turn the Geode on and enable Bluetooth. In Geode Connect tap the Geode/Bluetooth icon (top-right, shown with a slash when disconnected), pick your receiver by the serial number on its base, and complete pairing. The slash disappears once connected. 4. Open Receiver Configuration: Open the menu and go to Receiver Configuration (via the More (…) button or Settings, depending on version). 5. Open the NTRIP / RTK settings: In Receiver Configuration scroll down and open the NTRIP configuration screen ('NTRIP Configuration' or 'Configure NTRIP/RTK' by version). 6. Enter the caster and port: Caster/Server/IP Address: rtkpremium.xyz, Port: 2101. Protocol is standard NTRIP (no TLS/SSL needed). 7. Enter YOUR NTRIP credentials: Enter the NTRIP Username and Password from your welcome email - unique to your account; do not use anyone else's. If lost, contact Premium Positioning for a reissue. 8. Enable Send GGA to Caster: Tick 'Send GGA to Caster' so the Geode's rough position reaches the caster and it serves corrections for your area. Save the settings if there is a Save button. 9. Select the COMMON mount point: Tap 'Download Mount Points', then choose COMMON from the dropdown. If the list is empty, confirm host/port/credentials and your data connection, then download again. (Some versions let you type COMMON.) 10. Start NTRIP: Tap 'Start NTRIP' ('Start NTRIP/RTK' in some versions). Connecting can take up to about a minute. 11. Confirm RTK Fixed: On the home screen the NTRIP icon turns green with a closed plug when corrections flow (orange open plug = still connecting - recheck credentials, mount point, signal). Give the Geode open sky and let it converge Float → Fixed before relying on the position. 12. Feed the position to your GIS app (Android mock location): Android: Geode Connect > Menu > Preferences > tick 'Enable Mock Location Provider' > Save; enable Developer options; Settings > Developer options > 'Select mock location app' > Geode Connect. iOS: GIS apps like Esri Field Maps read the Geode location directly once Geode Connect is connected - no mock-location step. ### If the fix will not hold NTRIP/RTK needs continuous cellular data and a Geode model/subscription that supports RTK (e.g. GNS3 RTK). Settings live in the Geode Connect app, which must stay open while collecting. Menu/field labels differ between Geode Connect versions and between Android and iOS - match the nearest equivalent. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Leica Zeno FLX100 / GG04 plus Connect a Leica Zeno FLX100 or GG04 plus to RTK Premium corrections over NTRIP using Zeno Connect: caster settings and the steps to a fixed solution. These steps connect a Leica Zeno FLX100 / GG04 plus to the Premium Positioning correction network over NTRIP, using Zeno Connect (+ Zeno Mobile / GIS app). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-zeno-flx100-gg04-plus) to get your credentials. * Zeno Connect (+ Zeno Mobile / GIS app). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=leica-zeno-flx100-gg04-plus#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Install Zeno Connect & your GIS app: On the Android device install Leica Zeno Connect from Google Play, plus your field app (Zeno Mobile or a GIS app like ArcGIS Field Maps). Zeno Connect is the bridge that talks to the antenna and feeds corrected positions to your GIS app. The device needs internet (Wi-Fi or SIM). 2. Power on and pair the antenna over Bluetooth: Switch on the FLX100 / GG04 plus and wait for the GPS light to flash. In Android Settings > Bluetooth, find your FLX100 (or GG04) and pair/connect. You only pair once. 3. Select the antenna in Zeno Connect: Open Zeno Connect, tap the antenna selector at the top (reads e.g. 'No antenna selected') and choose your FLX100 / GG04 plus. When linked, the Connectivity light flashes blue. Menu name varies by version. 4. Open Realtime Corrections settings: Go to Settings > Realtime Corrections (some versions 'GPS Correction Profiles'). Tap + (top-right) to create a new correction profile and name it e.g. 'Premium Positioning'. 5. Choose Internet / NTRIP as the profile type: Select Internet, tap Next, then enable 'Use NTRIP'. Labels ('Internet', 'Use NTRIP', 'Next') vary slightly by version; pick the internet/NTRIP option. 6. Add the caster server (host + port): Tap + to create a server entry: Host / Server / RTK URL = rtkpremium.xyz, Port = 2101, Protocol = NTRIP. Save it, select it, tap Next. 7. Enter YOUR NTRIP username and password: Type YOUR OWN NTRIP credentials from your welcome email - unique to your account; do not use anyone else's. 8. Select the COMMON mountpoint: With the server selected, open the mountpoint list (tap the list icon to fetch mountpoints - needs internet) or type it, and choose COMMON. Tap Next, then Finish. 9. Activate the correction profile: Make sure your new profile is the active one, and the Antenna is still set to your FLX100 / GG04 plus. Zeno Connect dials the caster; on the receiver the data ('10101') light flashes green once corrections stream. 10. Set Zeno Connect as the Android location provider: Leave Zeno Connect running in the background. For FLX100 / GG04 plus, select it as an external Bluetooth GNSS receiver inside your GIS app's location/GNSS settings (choose Leica as the make). (On older GG02/GG03/GG04 you instead enable Zeno Connect under Developer options > 'Select mock location app'.) Wording varies by Android/app. 11. Wait for the position to converge: In Zeno Connect's main screen accuracy/height/position values populate. Hold the antenna with clear sky and stay still a minute or two while it converges from autonomous/float toward fixed. 12. Confirm a fixed, centimetre solution: You're ready once it reports FIXED with \~1 - 2 cm horizontal accuracy. In Zeno Mobile the RTK icon shows 'Connected to RTK' and accuracy drops to \~1 cm. If it stays float, recheck internet, COMMON, credentials, and sky view. ### If the fix will not hold Menu/button names differ between Zeno Connect versions and between Zeno Mobile and third-party GIS apps (e.g. ArcGIS Field Maps); where labels vary this guide is generic. A working mobile internet connection and clear sky are required to reach and hold a fixed RTK solution. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # SparkFun RTK Connect a SparkFun RTK Facet, Express+ or Torch to RTK Premium corrections over NTRIP using its built-in NTRIP client or SW Maps: caster settings and the steps to a fixed solution. These steps connect a SparkFun RTK (Facet / Express+ / Torch) to the Premium Positioning correction network over NTRIP, using Built-in NTRIP Client (WiFi web config) or SW Maps. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sparkfun-rtk) to get your credentials. * Built-in NTRIP Client (WiFi web config) or SW Maps. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sparkfun-rtk#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Decide your correction path: SparkFun RTK units pull corrections two ways: (A) the receiver's own built-in NTRIP Client over its WiFi web config page; or (B) feed corrections from a phone app such as SW Maps over Bluetooth. Path A suits reliable on-site WiFi; Path B suits the field with a phone hotspot. Steps 2-6 cover Path A; steps 7-10 cover Path B. 2. Path A - Power on and enter Config (WiFi) mode: Turn the unit on. Reaching Config mode depends on the model: RTK Torch - double-tap the Power button within 1 second (two beeps); RTK EVK - click the Mode button to highlight 'Config', then double-click; RTK Express+/Facet - use the Setup/power button to step to 'Config' / 'WiFi Config' on the display. Wording varies by firmware. The unit then broadcasts a WiFi network named 'RTK Config'. 3. Path A - Open the web config page: On your phone or laptop, join the 'RTK Config' WiFi network the receiver broadcasts. Open a browser (Chrome works best) to rtk.local. If that doesn't load, use the config IP shown on the receiver's display. 4. Path A - Connect the receiver to your local WiFi: In the web config, open the WiFi section and enter your local WiFi SSID and password (this is the internet the receiver uses to reach our caster - not the caster login). You can add fallback networks. 5. Path A - Enable the NTRIP Client and enter caster settings: Find the NTRIP Client section (under corrections/GNSS configuration; tab name varies by firmware) and enable it. Enter Caster Host rtkpremium.xyz, Caster Port 2101, Mountpoint COMMON. Protocol is NTRIP. Match by meaning if labels differ: host/address, port, mount point. 6. Path A - Enter YOUR caster username and password: Enter the NTRIP username and password from your welcome email into Caster User and Caster User PW (sometimes user/account name and password) - unique to your account; do not use anyone else's. Save; the unit exits Config and starts connecting. 7. Path A - Confirm corrections are flowing: The receiver joins your WiFi, then the caster. On units with a display the WiFi icon stops blinking and the solution should reach RTK Fix within \~30 s under clear sky. If it keeps retrying, recheck the WiFi SSID/password and your caster credentials. Skip the SW Maps steps below. 8. Path B - Pair the receiver over Bluetooth: Power on and note the four-character code on the display (last four of its MAC). In your phone's Bluetooth settings, pair the device whose name matches, e.g. 'Facet Rover-XXXX' or 'Torch Rover-XXXX'. 9. Path B - Connect in SW Maps: Open SW Maps > New Project. Open the menu (top-left) > 'Bluetooth GNSS'. Pick your RTK unit (instrument model 'SparkFun RTK') and press 'Connect'. Confirm it's connected. 10. Path B - Configure the NTRIP Client in SW Maps: Open the menu > 'NTRIP Client'. Enter address rtkpremium.xyz, Port 2101, Mountpoint COMMON, and YOUR welcome-email username/password. Enable 'Send NMEA GGA' (the caster needs your approximate position), then Connect. 11. Confirm RTK Fix: Watch the receiver display: a basic 3D solution → blinking cross-hair (RTK Float) → solid double cross-hair (RTK Fix). On display-less units (Torch), a solid/white status LED indicates RTK Fix. In SW Maps the fix type reads 'RTK Fixed' (\~10 - 20 mm). If you stay on Float, check sky view and the correction connection. ### If the fix will not hold SparkFun RTK models span two firmware families - RTK Express+/Facet (older 'RTK Firmware', u-blox ZED-F9P) and RTK Torch/EVK (newer 'RTK Everywhere Firmware', includes mosaic-X5) - so on-screen wording and menu layout vary by model and firmware; match fields by meaning (host, port, mount point, user, password). The standard NTRIP port is almost always 2101. Both paths give the same result. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Spectra MobileMapper 60 / Ashtech ProMark to the Premium Positioning correction network over NTRIP, using MobileMapper Field / FAST Survey (GIS). They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-mobilemapper-60-ashtech-promark) to get your credentials. * MobileMapper Field / FAST Survey (GIS). * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=spectra-mobilemapper-60-ashtech-promark#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Know what your unit can achieve: Identify whether you have a standalone GIS handheld (e.g. MobileMapper 60, internal antenna) or a survey-grade receiver (e.g. Ashtech ProMark / SP-series) paired to the handheld. A standalone GIS handheld with its internal antenna is a sub-metre/DGPS device - with corrections it improves accuracy but typically reaches sub-metre / decimetre, NOT centimetre 'Fixed' RTK. Centimetre RTK requires a survey-grade dual-frequency receiver. The NTRIP login is the same either way; only the achievable accuracy differs. 2. Get online and have your credentials ready: Connect the device to the internet (SIM data or Wi-Fi) - NTRIP streams over the internet. Have the NTRIP username and password from your welcome email to hand. These are unique to your account; enter your own and never share them. 3. Open your field software: On a MobileMapper handheld this is usually MobileMapper Field. On an Ashtech/ProMark or SP receiver used for survey work it is typically FAST Survey (or Survey Pro). Menu wording differs between apps and versions, so match the intent below to the labels you see. 4. Open the GNSS / correction settings: In MobileMapper Field, open the menu and go to Settings / GNSS or the 'Real-time' (corrections) section. In FAST Survey, go to Equip > GPS Rover. This is where you define how the receiver gets its real-time corrections. 5. Choose the receiver, then add a correction source: If prompted, select your receiver model first (internal GNSS for a GIS handheld, or your external receiver via Bluetooth for a survey unit). Then start creating a new real-time correction source / data link for the rover. 6. Set the correction link to Internet / NTRIP: For the correction data link, choose the option for receiving over the internet - 'Internet', 'NTRIP', or 'NTRIP Client' depending on the app. (Do not choose UHF radio or direct-IP.) In FAST Survey this is on the RTK / Data Collector internet/NTRIP setting under GPS Rover. 7. Enter the caster address and port: In the NTRIP server fields, enter Host / Server rtkpremium.xyz and Port 2101. Leave any 'use NTRIP' / 'NTRIP v1' option enabled if asked. 8. Enter your NTRIP username and password: In the Username and Password fields, type the credentials from your welcome email (case-sensitive). Use your own credentials only. 9. Connect and load the source table: Tap Connect / Get source table / GetTable (label varies). The device contacts the caster and downloads the source table (the mountpoint list). If nothing loads, recheck host, port, internet, and credentials. 10. Select the COMMON mountpoint: From the source table, select COMMON - the correction stream for all Premium Positioning customers. Confirm/OK the selection. 11. Start the survey / connect the rover: Save the configuration and start the survey (MobileMapper Field) or connect the GPS Rover (FAST Survey). The app opens the NTRIP connection and streams corrections from rtkpremium.xyz to your receiver. 12. Confirm a corrected solution: Watch the position-status indicator. A survey-grade receiver progresses Autonomous → Float → FIXED (cm RTK) - wait for FIXED before recording survey points. A standalone GIS handheld instead shows a 'corrected' / 'differential' (DGPS) status with sub-metre/decimetre accuracy and will not report a true RTK 'Fixed'. Check the reported accuracy matches what your hardware can deliver before collecting. ### If the fix will not hold Critical hardware note: the MobileMapper 60 (and similar GIS handhelds) is a sub-metre receiver - it does not produce centimetre RTK 'Fixed' on its own. Centimetre RTK requires a survey-grade Ashtech/SP receiver (e.g. ProMark/SP-series) connected to the handheld via Bluetooth and configured through FAST Survey or Survey Pro. Menu/button names vary by app and version; labels above are typical, not exact for every build. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Trimble Catalyst DA1 Connect a Trimble Catalyst DA1 to RTK Premium corrections over NTRIP using Trimble Mobile Manager: caster settings and the steps to a fixed solution. These steps connect a Trimble Catalyst DA1 to the Premium Positioning correction network over NTRIP, using Trimble Mobile Manager (Android) + a GIS app. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-catalyst-da1) to get your credentials. * Trimble Mobile Manager (Android) + a GIS app. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-catalyst-da1#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Check your Catalyst subscription tier: The DA1 is subscription-based, and achievable accuracy depends on the Catalyst subscription active on your Trimble ID. To use a custom NTRIP caster (your own/third-party corrections), you need a tier that permits custom/local corrections and cm-level (RTK) positioning. If unsure which tier you hold, check with Premium Positioning or your Trimble dealer. Tier names change over time, so this guide doesn't name a specific plan. 2. Install the apps and power on the DA1: Install 'Trimble Mobile Manager' (TMM) and the 'Catalyst Service' app from Google Play, plus your GIS app (e.g. ArcGIS Field Maps or QField). Connect the DA1 to your phone/tablet and power it on. Make sure the device has mobile data or Wi-Fi, since NTRIP streams over the internet. 3. Pair the DA1 over Bluetooth: Android Settings > Bluetooth, turn Bluetooth on, scan, tap the DA1 to pair. (Depending on DA1 connection type and TMM version, the Catalyst Service may detect it automatically - then skip manual pairing.) 4. Open Trimble Mobile Manager and sign in: Launch TMM and log in with your Trimble ID (the account holding your Catalyst subscription). This is your own Trimble account - Premium Positioning doesn't provide it. 5. Select the DA1 as the GNSS / position source: In TMM make sure 'DA1' is selected in the GNSS receiver type field and connect to it. The picker wording varies by version ('GNSS source', 'Position source', 'GNSS receiver type') - choose the option pointing TMM at the Catalyst/DA1 rather than the phone's internal GPS. 6. Open Configuration: From TMM's main screen open 'Configuration' (the configuration/settings icon) - where the correction source and reference-frame settings live. 7. Set the GNSS correction source to Custom local: In Configuration, change 'GNSS correction source' from 'Auto' to 'Custom local'. 'Auto' uses Trimble's built-in corrections; 'Custom local' points the DA1 at Premium Positioning's caster. 8. Choose the NTRIP protocol: Under the custom correction settings set 'Protocol' to 'NTRIP' (the other option is typically 'Direct' - leave it on NTRIP). 9. Enter the caster server and port: Server / URL: rtkpremium.xyz Port: 2101. TMM uses these to connect and download the mount point list. 10. Enter YOUR NTRIP username and password: Set the corrections account Username and Password to your NTRIP credentials from your welcome email - unique to your account; do not share them. If a field reads 'if required', it is required for this caster. 11. Select the COMMON mount point: After TMM connects, the mount point list (source table) appears. Select COMMON. If it doesn't load, re-check server, port, credentials and your internet connection. 12. Set the reference frame: Choose the 'GNSS source reference frame' matching the corrections. If unsure, contact Premium Positioning for the correct frame, or select 'Auto'. (Reference-frame wording varies by TMM version.) 13. Set TMM as the Android mock location app: To feed the cm position into a GIS app, Android must use TMM as its location provider. Enable Developer options (Settings > About phone > tap 'Build number' seven times), then Settings > System > Developer options > 'Select mock location app' > 'Trimble Mobile Manager'. Some GIS apps read the Catalyst position directly via TMM and don't need this. (Menu path varies by Android version.) 14. Confirm RTK Fixed and start surveying: In TMM, confirm the receiver is streaming corrections and the solution reaches 'RTK Fixed' with a low, stable accuracy estimate - not Autonomous/DGPS/Float. Then open your GIS app; its position should reflect the DA1's cm-level location. If it stays Float/Autonomous, recheck COMMON, your credentials, the subscription tier, and that the DA1 has clear sky. ### If the fix will not hold The DA1 is subscription-based: you must hold a Catalyst tier that allows custom/third-party corrections and RTK accuracy, otherwise TMM connects but won't reach RTK Fixed. TMM menu/field labels differ slightly between versions and Android devices - named generically where wording varies. RTK Fixed needs clear sky and a live internet connection.

These steps connect a Trimble Catalyst DA2 to the Premium Positioning correction network over NTRIP, using Trimble Mobile Manager (Android) + a GIS/field app. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-catalyst-da2) to get your credentials. * Trimble Mobile Manager (Android) + a GIS/field app. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-catalyst-da2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Check your Catalyst subscription: You need a paid Catalyst subscription that allows custom/third-party (local) corrections. On Catalyst Free, Configuration changes are NOT applied, so the NTRIP source below is ignored. If unsure, check with Trimble or your reseller first. 2. Power and pair the DA2: Power the DA2 (e.g. from a USB power bank) and press the power button - a flashing blue light means it's ready to pair. On Android, open Settings > Bluetooth and pair the DA2; a solid blue light means connected. Keep it in clear sky. 3. Sign in to Trimble Mobile Manager: Install and open Trimble Mobile Manager (TMM) from Google Play. Sign in with the Trimble Identity that holds your Catalyst subscription. 4. Select the DA2 as the position source: On the TMM Home screen open the position source menu ('Position source' > 'Select position source' > 'List connected devices') and choose your paired DA2. Wording varies slightly by TMM version. 5. Open Configuration: Tap the configuration icon in TMM and select 'Configuration' to open the receiver settings where corrections are set. 6. Set the correction source to Custom local: Tap 'GNSS correction source' and select 'Custom local' - this uses your own NTRIP caster instead of Trimble's services (RTX / Correction Hub). 7. Choose the NTRIP protocol: For 'Protocol' select 'NTRIP' (the alternative, 'Direct', is not used here). 8. Enter the caster server and port: Server/URL 'rtkpremium.xyz' and Port '2101'. TMM uses these to connect and download the mount point (source) table. 9. Enter your NTRIP username and password: Set the corrections account username/password to YOUR OWN Premium Positioning NTRIP credentials from your welcome email - per-customer; don't use example values. 10. Retrieve and select the mountpoint: Once TMM connects and the mount point list appears, select COMMON. If the list doesn't appear, re-check server, port, credentials and internet. 11. Set the reference frame: Select the 'GNSS source reference frame' used by the correction source. If unsure which frame Premium Positioning uses, contact us; otherwise 'Auto' lets TMM pick the best available. Set a custom epoch only if advised. 12. Connect and start corrections: Return Home and enable 'Connect to position source' so TMM streams NTRIP corrections to the DA2. Position quality moves from autonomous toward a corrected RTK solution. 13. Set TMM as your location provider: So your GIS/field app uses the corrected position: on Android enable Developer options, then under 'Select mock location app' choose Trimble Mobile Manager (keep TMM running in the background). In apps supporting Trimble TIP positions (e.g. ArcGIS Field Maps), select TMM/TIP inside that app instead. 14. Confirm an RTK Fixed solution: Check TMM (and your field app's GNSS status): with corrections and good sky view the solution should report RTK Fixed (cm precision). If it stays Float/autonomous, confirm open sky, an active NTRIP connection, and that your subscription permits custom corrections. ### If the fix will not hold Requires a paid Catalyst subscription that permits custom/local NTRIP corrections - Catalyst Free ignores Configuration changes. Menu/field names vary slightly between TMM versions; look for the equivalent 'GNSS correction source', 'Custom local', 'Protocol/NTRIP', server/port, mount point and credential fields. RTK Fixed requires open sky and a live internet connection on the phone/tablet. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Trimble TDC650 handheld to the Premium Positioning correction network over NTRIP, using Trimble Mobile Manager + TerraFlex/Penmap. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-tdc650-handheld) to get your credentials. * Trimble Mobile Manager + TerraFlex/Penmap. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-tdc650-handheld#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Open Trimble Mobile Manager: Trimble Mobile Manager (TMM) drives the TDC650's built-in GNSS and feeds corrected positions to your field app (TerraFlex, Penmap, Esri Field Maps). Open TMM and complete this setup before opening your field app. 2. Select the internal GNSS receiver: On the TMM Home screen tap Select. The TDC650's integrated GNSS appears in the Select device window (there is no separate Bluetooth receiver to pair). Choose the internal/integrated receiver and tap Connect. 3. Open Configuration: Tap the configuration icon, then Configuration. Wording can differ slightly between TMM versions - look for the Configuration / GNSS configuration option. 4. Set correction source to Custom local: Tap GNSS correction source and change it from Auto to Custom local, so you supply your own NTRIP caster details. 5. Set Protocol to NTRIP: Set Protocol to NTRIP (the other option is Direct). 6. Enter the caster server and port: Server (URL): rtkpremium.xyz Port: 2101. TMM uses these to connect and download the mount point list. 7. Enter YOUR NTRIP username and password: Enter the NTRIP username and password from your welcome email - unique to your account; use your own credentials exactly as supplied. 8. Select the COMMON mount point: After TMM connects to rtkpremium.xyz the mount point list shows. Select COMMON. If it doesn't appear, re-check server/port/credentials and that the device has mobile data or Wi-Fi. 9. Set the reference frame: Set the GNSS source reference frame to the datum the COMMON service uses (your welcome email or support can confirm). If unsure, select Auto. Leave Customize epoch off unless told otherwise. 10. Save the configuration: Save / apply Configuration so TMM streams corrections from COMMON to the TDC650's internal GNSS. 11. Set TMM as the Android mock location app: So TerraFlex/Penmap/Field Maps get the corrected position: Settings > enable Developer options > Select mock location app > Trimble Mobile Manager. Also disable battery optimisation for TMM. 12. Confirm an RTK Fixed solution: On the TMM Home screen check the position accuracy. Wait until it converges to RTK Fixed (cm-level) before collecting. If it stays lower-precision, re-check COMMON, credentials, internet, and sky view. ### If the fix will not hold The TDC650 has integrated GNSS, so no external Bluetooth receiver is needed. Labels and the home-screen status wording vary between TMM versions and field apps (TerraFlex/Penmap/Field Maps) - match by purpose. The same caster settings work in third-party apps once TMM is set as the Android mock location app. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps bring RTK Premium corrections into ArcGIS Field Maps over NTRIP, through your receiver or its companion app. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=arcgis-field-maps) to get your credentials. * ArcGIS Field Maps app (+ receiver/companion app for NTRIP). * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Understand the two-part setup: ArcGIS Field Maps does NOT have its own NTRIP client. The cm-level correction (NTRIP) is configured on your GNSS receiver or its companion app (e.g. Trimble Mobile Manager, Eos Tools Pro, Emlid Flow, or the receiver's own NTRIP client). Field Maps then reads the corrected position from that receiver. So: (1) get the receiver onto Premium Positioning corrections, then (2) connect Field Maps to the receiver. 2. Pair the receiver to your phone/tablet first: Turn on your GNSS receiver and pair it over Bluetooth in the device's system settings (or via the receiver's companion app). Field Maps can only see receivers that are already paired/connected. 3. Open your receiver's NTRIP settings (companion app or on-receiver): Open the app that controls your receiver and find its NTRIP / correction / RTK source settings. This varies by brand: Trimble/Spectra use Trimble Mobile Manager > correction source; Eos Arrow uses Eos Tools Pro > RTK/NTRIP; Emlid uses Emlid Flow > Correction input > NTRIP; some controllers have NTRIP built in. Use your receiver's manual for the exact menu name. 4. Enter the Premium Positioning caster details: In that NTRIP screen, enter Host/Server rtkpremium.xyz, Port 2101, Protocol NTRIP. (Labels may read 'Address', 'Caster', 'Server'.) 5. Enter YOUR NTRIP username and password: Enter your own NTRIP username and password from your welcome email - unique to your account; do not use anyone else's. Field Maps never sees these; they live only on the receiver/app. 6. Select the COMMON mountpoint: After the connection details are entered, pick the mountpoint (sometimes 'Source table', 'Stream', or 'Data stream') - choose COMMON. If you must connect before the list loads, type COMMON manually. 7. Confirm the receiver itself reaches a Fixed solution: In the receiver's app, wait until it reports RTK Fixed ('Fixed', 'RTK Fix', or a fix-type indicator with sub-3 cm accuracy). Don't move on until the receiver shows Fixed; if it stays 'Float' or 'Single', recheck the caster values, credentials, mountpoint, and your internet. 8. Open Field Maps and go to the location provider settings: In Field Maps, from the Maps list tap your Profile icon, then under Location tap Provider. (Wording shifts slightly between app versions and iOS/Android, but it's under Profile/Settings > Location > Provider.) 9. Add your receiver as a provider: Tap Add Provider (a '+' on some versions), then select your receiver from the available/paired devices. For Trimble/Spectra receivers, choose the 'Trimble Mobile Manager' provider so Field Maps reads the corrected position from TMM. 10. Set the antenna height: When prompted, enter the antenna height in metres (ground/range-pole tip up to the antenna). Note: some receivers (e.g. via TMM, or those that auto-apply the antenna phase-centre offset) want the height set in their own app instead - follow your receiver's guide and don't enter it twice. Tap Done/Save. 11. Make this receiver the current provider: Back in the provider list, tap your receiver to make it the active location source. Field Maps now uses the receiver's corrected position instead of the phone's internal GPS. 12. Set or pick a Location Profile (coordinate system / datum): Under Profile > Location, tap Profile (the location profile, not your user profile). Add a profile matching your correction service's coordinate system (GNSS coordinate system, map coordinate system, datum transformation if offered). If unsure, the default assumes WGS 1984 - check with Premium Positioning which reference frame applies. 13. Confirm a Fixed / cm-level position inside Field Maps: Return to the map. Tap the GPS/location button or accuracy banner to view the location status. Confirm Field Maps is reading from your receiver and showing a small horizontal accuracy (a few centimetres). If accuracy is metres, the receiver dropped out of Fixed - recheck the NTRIP connection in the receiver's app. Once cm-level, you're ready to collect high-accuracy data. ### If the fix will not hold Field Maps has no built-in NTRIP client - all correction settings (host rtkpremium.xyz, port 2101, mountpoint COMMON, NTRIP, plus your personal username/password) are entered in the receiver or its companion app (TMM, Eos Tools Pro, Emlid Flow), not in Field Maps. Field Maps connects via Profile > Location > Provider and reads the corrected position. UI labels and antenna-height handling vary by version/receiver. Achieve Fixed on the receiver first, then confirm cm accuracy in Field Maps. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps bring RTK Premium corrections into ArcGIS Survey123 over NTRIP, through your receiver or its companion app. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=arcgis-survey123) to get your credentials. * ArcGIS Survey123 app (+ receiver/companion app for NTRIP). * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Understand the setup (read first): ArcGIS Survey123 does NOT have its own NTRIP client - it can't dial a caster directly. Your GNSS receiver (or its companion app) connects to Premium Positioning's NTRIP service and computes the corrected RTK position; Survey123 reads that position. So: (1) set up NTRIP on the receiver / its app, (2) connect Survey123 to that receiver. Have your welcome email handy for your NTRIP username/password. 2. Have your details ready: You need the NTRIP settings (same for all): Host rtkpremium.xyz, Port 2101, Mountpoint COMMON, Protocol NTRIP; plus your personal NTRIP username/password from the welcome email. Enter your own credentials only. 3. Configure NTRIP in your receiver's companion app: Open the app that controls your receiver - e.g. Trimble Mobile Manager (Trimble), Emlid Flow (Emlid), Eos Tools Pro (Arrow), or the receiver's own NTRIP screen. Find the 'Correction source' / 'NTRIP' / 'RTK' / 'Real-time corrections' section (wording varies by brand/version) and add an NTRIP / NTRIP Client connection. 4. Enter the Premium Positioning caster settings: In that NTRIP form enter Server/Host = rtkpremium.xyz, Port = 2101, then your NTRIP Username and Password from the welcome email. Save/connect. This is the ONLY place your NTRIP login is typed - into the receiver/app, never into Survey123. 5. Select the COMMON mountpoint: After connecting, the app retrieves the source table. Select COMMON. If asked, let it send your position (GGA) to the caster. Some apps require you to connect first, then pick the mountpoint. 6. Confirm the receiver reaches RTK Fixed: Watch the receiver/app status: Autonomous/Single → DGPS/Float → RTK Fixed ('Fixed', 'RTK', or a cm-level accuracy figure). Don't proceed until the receiver itself reports Fixed - Survey123 only inherits the receiver's accuracy. 7. Make the corrected position available to Survey123: On iOS/Windows and most Android setups, Survey123 connects to the receiver directly over Bluetooth (or network/TCP). On some Android workflows where a separate app supplies RTK, enable that app as a mock-location provider and point Survey123 at the device's 'Integrated provider'. Check your receiver's Esri integration notes for which applies. 8. Open Location settings in Survey123: In Survey123 open the main menu > Settings > Location. (If your version differs, look for the 'Location' or 'GPS/Receiver' area under Settings.) 9. Add your receiver as a location provider: Choose 'Add provider' ('Add a location provider' / 'Add receiver'). Pick the connection type matching your setup: an external Bluetooth receiver (default), a Network connection (enter the receiver's IP and TCP port), or - for the mock-location route on Android - the device's Integrated provider. Select your receiver and connect. 10. Set antenna height and connection alerts: Open the provider's settings, name it, and set the Antenna height (antenna phase centre / receiver to the ground or survey point; Survey123 subtracts this from captured altitude). Optionally enable alerts if the link drops. Note: there's no NTRIP field in Survey123 - it stays in the receiver/companion app. 11. Check the location status in Survey123: Back on the Location screen, Survey123 shows live fix details from the receiver. Confirm it reports the corrected position - a Fixed/RTK fix type with cm-level accuracy, matching the receiver. If Survey123 shows only GPS/autonomous (metres), the corrected stream isn't reaching it - recheck the connection and the receiver's RTK status. 12. Prepare the survey for high accuracy (survey author): In the survey design, set quality controls on the geopoint question: an accuracy threshold (body::accuracyThreshold for averaging), optionally a constraint to block submission above a limit, or bind::esri:warning to warn the user. Capture GNSS metadata with pulldata('@geopoint', ...) for fields like accuracy and fix type. Match the survey's coordinate settings to the corrections' reference frame. 13. Capture a point and verify the cm-level fix: Add a geopoint. Confirm Survey123 shows a Fixed / RTK solution with cm-level accuracy (within your threshold) before recording. Let averaging settle if used, then save. If the fix drops to Float/autonomous, let the receiver re-establish RTK Fixed via COMMON before collecting. ### If the fix will not hold Survey123 has no internal NTRIP client - corrections are set up on the receiver or its companion app (TMM, Emlid Flow, Eos Tools Pro, or the receiver's own NTRIP screen); Survey123 reads the corrected position over Bluetooth, network/TCP, or (on some Android setups) a mock/integrated provider. Caster (same for all): rtkpremium.xyz / 2101 / COMMON / NTRIP; your personal credentials go into the receiver/app, never Survey123. Labels vary by Survey123 version and receiver brand. A Fixed solution depends on the receiver reaching RTK first.

These steps set up FieldGenius for Android to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=fieldgenius-for-android) to get your credentials. * FieldGenius for Android app. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and connect to the internet: Turn on your GNSS receiver and your Android device. FieldGenius sends NTRIP corrections over the data collector's connection, so make sure the Android device has internet (SIM or hotspot/Wi-Fi). FieldGenius works with many receiver brands (Emlid, Leica, Trimble, Topcon, CHCNAV, Stonex and others) via its drivers. 2. Open your project: Launch FieldGenius for Android and open or create a project to reach the main map screen. 3. Select the GNSS instrument profile: Tap 'Select Instrument', choose 'GNSS Rover' and add a new profile (name it after your receiver). For receivers without a dedicated driver, a generic profile (Make 'NMEA', Model 'Basic') is common - pick the named brand driver if listed. 4. Set up Bluetooth communication: Open 'Set Up Communication' (older builds: Edit → 'Model and Communication'). Set connection type to 'Bluetooth', tap 'Search', select your receiver, pair (some prompt for a PIN such as 123456), then 'Connect' and confirm it's connected. 5. Open the corrections / data source setup: Open 'Set Up Corrections' (or the three-dot menu next to 'Corrections' on the GNSS Rover screen). Older builds: Instrument Settings → 'Link Configure'. Wording varies by version - look for the corrections/reference data-source area. 6. Choose internet (NTRIP) corrections: Choose 'RTK via Internet' with the link device set to 'Data collector' ('Data Collector Internet') so FieldGenius streams NTRIP through the Android connection rather than a radio or the receiver's modem. 7. Add a new NTRIP correction source: Tap 'Set Up Data Source' then 'Add New Source' (older builds: 'Press to Modify' → NTRIP Casters → 'Add'). 8. Enter the Premium Positioning caster: Name: any label (e.g. 'Premium Positioning'); Address / Server / Host: rtkpremium.xyz; Port: 2101; Protocol: NTRIP. Leave the mount point empty for now. 9. Enter your NTRIP username and password: Enter YOUR OWN NTRIP credentials from your Premium Positioning welcome email - unique to your account. Save the source ('Done'). 10. Connect and retrieve the source table: Select the source and tap 'Connect'. FieldGenius downloads the NTRIP source table (mountpoints). Wait for the port to finish configuring. 11. Select the COMMON mountpoint: From the source table choose COMMON. If your account has one stream it may already be selected; otherwise tap COMMON. 12. Confirm correction format and NMEA, then the mountpoint: Check 'Correction Format' (e.g. RTCM 3.x) and 'NMEA Required' - most network/VRS services need NMEA sent back, so leave it enabled unless told otherwise. Tap 'Confirm Selected Mountpoint' and wait for the link to configure. 13. Set antenna height and tolerances: Enter your antenna/pole height and accuracy tolerances so stored points meet your job's requirements. Tap 'Done' to return to the survey screen. 14. Confirm a Fixed solution: Watch the status move Autonomous → Float → RTK Fix. The receiver LED usually turns solid green when fixed. Collect points only once Fixed is stable. If it stays Float/Autonomous, re-check internet, the COMMON mountpoint, credentials, and sky view. ### If the fix will not hold FieldGenius for Android is receiver-agnostic and supports many brands via its driver list, so wording differs slightly between versions/drivers - if a label doesn't match, find the nearest equivalent ('Set Up Data Source' vs 'Link Configure', 'Set Up Communication' vs 'Model and Communication'). Caster settings are the same for everyone; your username/password are personal and entered on the device only.

FieldGenius works with many brands (Leica, Trimble, Topcon, Emlid, CHCNAV, Stonex, South, Hi-Target and others) - the NTRIP steps are the same regardless. 2. Open a project, then go to Instrument Selection: Launch FieldGenius and open/create your project. Open Instrument Selection (typically Main Menu > Settings > Instrument Selection, or the Settings/instrument button on the GNSS toolbar). The exact path varies slightly by version. 3. Choose GNSS Rover and pick a profile: Set the instrument type to 'GNSS Rover'. Select an existing profile or tap 'Add' to create one and name it (e.g. 'Premium Positioning NTRIP'), then 'Edit' to open the rover configuration. 4. Open Link Configure: In the rover configuration, open 'Link Configure' (sometimes via 'Instrument Settings' or 'Model and Communication', by version) - where you tell FieldGenius how corrections reach the receiver. 5. Set the correction link to internet (NTRIP): For the Link Device / Device Type, choose the option that streams corrections over the data collector's internet - commonly 'Data Collector Internet' (some versions phrase it as RTK corrections via internet / NTRIP). Then tap 'Setup' ('Press to Set up' / 'Press to Modify'). Labels vary - pick the internet/NTRIP option. 6. Open the NTRIP caster list and Add a new caster: In the NTRIP setup dialog, open the NTRIP Casters list and tap 'Add'. Give it a description such as 'Premium Positioning'. 7. Enter the caster address and port: Set the server Address / Host to rtkpremium.xyz and the Port to 2101. Leave the protocol as NTRIP. The same for every customer. 8. Enter YOUR NTRIP username and password: Enter the NTRIP Username and Password from your welcome email - unique to your account; sent from the device directly to the caster. Save the caster entry (tap 'OK'). 9. Select the caster and connect: Select the 'Premium Positioning' caster and tap 'OK' to load it into Link Configure. Confirm rtkpremium.xyz, 2101 and your username are populated, then tap 'Connect'. 10. Request the source table and choose COMMON: When prompted to 'Request Source Table' (or fetch the mountpoint list), choose Yes. From the returned list select COMMON and tap 'Select'. If the list doesn't appear, re-check internet, address/port, and your credentials. 11. Finish the link setup and start the rover: Confirm/OK out of Link Configure and the rover configuration to save the profile, then tap 'Connect' on Instrument Selection to start the rover with the NTRIP link active. FieldGenius reports it is receiving corrections. 12. Confirm RTK Fixed before you survey: Check the GNSS status indicator (status bar / GNSS toolbar). Wait until it reads 'RTK Fixed' (not Float or Autonomous), with a healthy satellite count and low estimated precision. Only collect points once you have a stable RTK Fixed solution. ### If the fix will not hold FieldGenius for Windows is brand-agnostic; the NTRIP workflow is the same across receivers. Button/screen labels ('Data Collector Internet', 'Press to Set up', 'Request Source Table', etc.) differ between FieldGenius versions and Windows / Windows Mobile builds - choose the equivalent internet/NTRIP option. The data collector needs working internet (Wi-Fi, or a SIM/hotspot). For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # GNSS Master (app) Set up the GNSS Master app on Android or iOS to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution. These steps set up the GNSS Master app on Android or iOS to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=gnss-master-app) to get your credentials. * GNSS Master app (Android/iOS). * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. What you'll need: GNSS Master is a brand-agnostic app (published by Bad Elf) that connects to many Bluetooth/BLE GNSS receivers - u-blox-based units, ArduSimple, and others - and feeds them NTRIP corrections. You'll need: your receiver powered on and paired to your phone, the GNSS Master app installed, and your personal Premium Positioning NTRIP username and password from your welcome email. Use YOUR OWN credentials. 2. Pair the receiver in your phone first: Before opening the app, pair your receiver in your phone's system Bluetooth settings. GNSS Master selects from already-paired devices, so it must show up there first. Some BLE receivers connect inside the app instead - if yours isn't listed, that's expected; you'll pick it in the next step. 3. Open the GNSS Receiver Connection page: Launch GNSS Master and open the GNSS Receiver Connection page (from the navigation drawer / menu, or via the gear/settings icon next to the receiver connection). Wording varies slightly by version - look for the receiver connection or device settings screen. 4. Choose the connection mode and connect: On the connection page, open the Mode dropdown and pick how your receiver links: 'Bluetooth' for classic Bluetooth (SPP), or 'Bluetooth LE' for BLE. (GNSS Master also supports USB Serial/OTG and TCP/IP.) Select your receiver from the list, then press Connect. You should see live position data once linked. 5. Open the Corrections page: Open the Corrections page (sometimes 'Correction Input', from the navigation drawer or a gear/settings icon - label varies by version). This is where you tell the app where to get RTK corrections. 6. Set the correction Mode to NTRIP Client: On the Corrections page, open the Mode dropdown and select 'NTRIP Client' - so GNSS Master pulls corrections from an NTRIP caster. 7. Add a new NTRIP connection: Press the '+' button (Add NTRIP Connection) to open the NTRIP Client dialog. If asked for an NTRIP version, choose V2 if available; if it doesn't connect, fall back to V1. Field labels vary slightly between versions. 8. Enter the caster address and port: In the NTRIP Client dialog, enter the caster host/address rtkpremium.xyz and Port 2101 - the same for every customer. Protocol is NTRIP. 9. Enter the mountpoint: For the Mount point ('Mountpoint' or 'Data stream'), enter COMMON (in capitals). If the app offers a 'Get'/source-table button next to the field, you can tap it to list streams and pick COMMON - typing it directly works too. 10. Enter YOUR NTRIP username and password: In the Username and Password fields, enter the personal credentials from your welcome email - unique to you; do not share them. If you can't find them, contact support; the connection won't authenticate without valid credentials. 11. Enable Send NMEA GGA: Tick 'Send NMEA GGA to Base Station' ('Send GGA' or 'Send position'). The COMMON stream needs your approximate position to send the right corrections, so this must be ON. The app sends your position automatically once the receiver has a basic fix. 12. Save and connect: Press Save. The new NTRIP connection appears in the list - select it and press Connect. Watch for corrections flowing (an active/connected state, incoming bytes, or a falling correction age). 13. Confirm RTK Fixed: Open the GNSS Status page and check the fix type: Single → DGPS/Float → 'RTK Fixed' (\~1 - 2 cm). If it stays on 'RTK Float', give it a clear sky view and a minute or two. Once it shows RTK Fixed you're receiving Premium Positioning corrections and ready to work. ### If the fix will not hold GNSS Master is brand-agnostic and works with many Bluetooth/BLE GNSS receivers, not just Bad Elf hardware. Menu/field names (Corrections vs Correction Input, Mount point vs Mountpoint, gear icon vs navigation drawer) vary by app version and platform - match the described screens. If it won't authenticate, double-check credentials and try NTRIP V1 vs V2; if it won't reach RTK Fixed, ensure 'Send NMEA GGA' is enabled and the antenna has open sky. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # HYPACK Connect a GNSS device in HYPACK to RTK Premium corrections over NTRIP. These steps connect a GNSS device in HYPACK hydrographic survey software to the Premium Positioning correction network over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=hypack) to get your credentials. * Your GNSS device configured in HYPACK Hardware. * A working internet connection on the survey computer. * A clear view of the sky at the GNSS antenna. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Configure the GNSS driver: In HYPACK Hardware, configure the driver for your GNSS device. 2. Open the NTRIP client settings: Set up the NTRIP client for your GNSS device. 3. Enter the caster address and port: Enter rtkpremium.xyz as the caster and 2101 as the port. 4. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account. 5. Set the mountpoint: Enter COMMON as the mountpoint. 6. Forward GGA to the caster: Make sure GGA is forwarded to the caster so the network receives your approximate position. 7. Confirm a fixed solution: Confirm a fixed RTK solution before you start the survey. ### If the fix will not hold NTRIP setup differs between HYPACK versions and GNSS drivers, so match the nearest equivalent for your configuration. Keep the survey computer online for the whole survey. If the solution will not reach or hold a fixed RTK solution, check that GGA reaches the caster, then recheck the caster address, the port, the COMMON mountpoint and your credentials. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Lefebure NTRIP Client (Android) Set up Lefebure NTRIP Client on Android to stream RTK Premium corrections to your receiver: caster settings and the steps to a fixed solution. These steps set up Lefebure NTRIP Client on Android to stream RTK Premium corrections to your receiver. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=lefebure-ntrip-client-android) to get your credentials. * Lefebure NTRIP Client app. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Install and open the app: Install 'Lefebure NTRIP Client' from Google Play and open it. The main screen shows your position and fix status. Open Settings via the gear icon - it lists Display Settings, Receiver Settings, NTRIP Settings and Premium Features. 2. Pair your GNSS receiver over Bluetooth: Pair your RTK receiver in Android's Bluetooth settings first so it appears in the device list. (For a cm position inside other apps only, you can use the phone's internal GNSS instead - accuracy then depends on the phone.) 3. Open Receiver Settings: Go to Settings > Receiver Settings - this is where you tell the app how it talks to your hardware. Wording varies slightly by version; match by meaning. 4. Set the Bluetooth connection: Set 'Bluetooth Connection Method' to connect to an external receiver via Bluetooth, then pick your paired receiver. Enable 'Auto-Enable Bluetooth'. (For the phone's internal GNSS, choose the internal/standalone option here.) 5. Enable mock locations (only if feeding other apps): If you want the corrected position in other Android apps, enable 'GPS Mock Locations' here, then in Android Developer Options set 'Select mock location app' to Lefebure NTRIP Client. Skip if you only need the position inside Lefebure. 6. Open NTRIP Settings: Go back to Settings and open NTRIP Settings - where you enter the Premium Positioning caster details. 7. Choose the network protocol: Set 'Network Protocol' to NTRIP. If asked for a version, NTRIP v1 works for our caster (v2 also fine). Wording varies by version - pick the plain NTRIP option. 8. Enter the caster address and port: Set 'Caster IP' to rtkpremium.xyz and 'Caster Port' to 2101 (fixed for all customers). The field may read 'Caster IP' or 'Caster Address' depending on version - enter the same host value. 9. Enter YOUR username and password: Enter the NTRIP Username and Password from your welcome email - unique to you. If you don't have them, contact support. 10. Load the source table and select the mountpoint: Use the option that retrieves/updates the source table (often via the 'Data Stream' field or an 'Update Source Table' action) to download the streams, then select mountpoint COMMON as your data stream. 11. Set a reported location if prompted: The caster needs your approximate position to start sending corrections. If your receiver outputs GGA this is automatic; otherwise use 'Reported Location' in NTRIP Settings to supply an approximate position. 12. Connect: Return to the main screen and press 'Connect'. The app connects to the receiver and caster; you should see RTCM data received and a byte counter increasing. 13. Confirm a fixed solution: Watch the fix-status indicator. Under open sky it should progress from autonomous to 'Float' then to a fixed RTK solution ('RTK' / 'Fixed'), usually within a minute. A fixed status with cm-level accuracy confirms corrections are working. ### If the fix will not hold Lefebure NTRIP Client is brand-agnostic and works with many Bluetooth GNSS receivers. Label names vary slightly between versions; match the closest equivalent. Mock locations is only needed to feed the corrected position to other Android apps. For a fix you need clear sky and an RTK-capable receiver; if you stay on Float, check sky view, credentials, and that the COMMON stream is selected. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Mapit GIS (Android) Set up Mapit GIS on Android to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution. These steps set up Mapit GIS on Android to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=mapit-gis-android) to get your credentials. * Mapit GIS app. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Check your subscription: The built-in NTRIP client and external RTK corrections require a paid Mapit GIS tier (currently Mapit Pro Plus). The free tier and basic Pro can't connect to a caster. Check Settings or your account and upgrade if NTRIP options are greyed out or hidden. 2. Pair your receiver in Android: Power on your external Bluetooth GNSS receiver and pair it first in Android Settings > Bluetooth (outside Mapit). If prompted for a PIN, use the one in your receiver's manual (commonly 0000 or 1234). The receiver must output NMEA and accept RTCM3. 3. Connect the receiver in Mapit: In Mapit GIS open the menu > Settings > External GNSS (the external/Bluetooth receiver section). Enable the external/direct connection and pick your paired receiver. Look for 'External GNSS' and a connect / 'Direct connection' toggle (wording varies by version). 4. Confirm raw GNSS is live: Open the GPS Info sheet (location/accuracy panel). You should see a position and a fix status like 'GPS (SPS)' with metre-level accuracy - confirming the Bluetooth link works before adding NTRIP. 5. Open NTRIP Corrections: Settings > NTRIP Corrections (NTRIP Client). Tap 'Add Configuration' (or '+' / 'Add') to create a new caster profile. Label varies by version. 6. Name the profile: Give it a recognisable name, e.g. 'Premium Positioning' - just a label for your reference. 7. Enter the Premium Positioning caster: Host (Caster/Server address) = rtkpremium.xyz, Port = 2101, Protocol = NTRIP. If a version field shows, V1 or V2 both work; leave the default if unsure. 8. Enter YOUR NTRIP credentials: In Username and Password enter the personal credentials from your welcome email - unique to your account; do not use anyone else's. There is no generic login. 9. Select the COMMON mountpoint: Tap the Mountpoint field. Mapit fetches the source table and lists mountpoints (often by distance, with a search box). Select COMMON, or type it directly. 10. Keep Send GGA enabled: Leave 'Send GGA' on (the default) - the caster needs your approximate position via GGA. A \~10 s interval is fine. 11. Point corrections at your receiver and connect: If asked where to send corrections, choose your Bluetooth receiver so the RTCM3 is forwarded to it. Tap Connect (or Start Service / play). If it fails, re-check the username/password, Host rtkpremium.xyz, Port 2101, and that COMMON is selected. 12. Confirm an RTK Fixed solution: Open the GPS Info sheet and watch GPS (SPS) → DGPS → RTK Float → RTK Fixed (green NTRIP indicator). Wait for 'RTK Fixed' (\~1 - 3 cm, low correction age) before collecting. Initial fix typically 15 - 60 s under open sky. ### If the fix will not hold The built-in NTRIP client requires a paid Mapit tier (currently Mapit Pro Plus). Mapit GIS is brand-agnostic and works with many Bluetooth GNSS receivers (must output NMEA and accept RTCM3). Menu/button labels ('External GNSS', 'NTRIP Corrections', 'Add Configuration', 'Send GGA') vary slightly between versions and Android/iOS - match the closest equivalent. Keep 'Send GGA' enabled. Work under open sky for a reliable fix. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Mergin Maps Set up Mergin Maps to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution. These steps set up Mergin Maps to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=mergin-maps) to get your credentials. * Mergin Maps / Input app (QGIS). * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Important: Mergin Maps has no built-in NTRIP client: Mergin Maps (the Input app) does NOT receive RTK corrections itself - it only reads the finished, corrected position over Bluetooth from your GNSS receiver. So the caster details (host, port, mountpoint, username, password) go into your GNSS RECEIVER or its own companion app (e.g. Emlid Flow, Leica Zeno Connect, Trimble Mobile Manager, GNSS Master, SW Maps, or a generic NTRIP client app) - NOT into Mergin Maps. Set up corrections on the receiver first, then connect Mergin Maps to it. 2. Enter the NTRIP caster details in your receiver's app: Open your receiver's companion app and add a new NTRIP correction source / NTRIP client profile: Host rtkpremium.xyz, Port 2101, Mountpoint COMMON, Protocol NTRIP. For Username/Password enter YOUR OWN from your welcome email - unique to your account; do not reuse anyone else's. 3. Confirm the receiver is getting corrections: In the receiver's app, start the NTRIP client and confirm corrections are flowing (incoming bytes/age of corrections) and the status progresses single/autonomous → FLOAT → FIXED. You must reach FIXED on the receiver before Mergin Maps can report cm accuracy. Stay outdoors with clear sky and a working data connection. 4. Pair the receiver with your phone/tablet over Bluetooth: In your device's system Settings > Bluetooth, make the receiver discoverable and pair it (complete any PIN prompt). Done once per device. 5. Open Mergin Maps and go to Settings: Launch Mergin Maps (Input), open your project, tap More (bottom toolbar) and open Settings. Find the GPS section. 6. Open Manage GPS receivers: In the GPS section tap Manage GPS receivers (older versions: Select GPS receiver) - where Mergin lists internal and external position sources. 7. Connect to your paired receiver: Tap Connect new receiver(s), then choose your GNSS receiver from the paired Bluetooth devices. Mergin connects and reads the position stream (NMEA) from the receiver. 8. Set the antenna height: In the GPS settings, set the GPS antenna height - ground to the antenna reference point plus any antenna offset (pole height plus antenna phase-centre offset). You can also store it automatically via the @position\_gps\_antenna\_height variable in your form. 9. Confirm the source is your external receiver: Tap the GPS accuracy button (bottom-left of the map). In the GPS info panel, check that Source shows your external GPS device name, not the phone's internal GPS. 10. Check accuracy and fix quality: In the same panel review Horizontal/Vertical accuracy, Satellites, and the fix details. With corrections working on the receiver, horizontal accuracy should fall to \~1 - 2 cm. The GPS accuracy button colour reflects whether you're within your accuracy threshold. 11. Set your accuracy threshold (optional): In GPS settings set the GPS accuracy threshold so the GPS button turns a good colour only when you're within your required accuracy (e.g. a few centimetres) - a quick visual confirmation while surveying. 12. Confirm an RTK fix before recording: Verify the receiver reports FIXED and Mergin shows cm-level horizontal accuracy with your external receiver as the source. If you see only FLOAT or sub-metre, wait for the receiver to converge to FIXED (check sky view, data, and that the NTRIP client is still connected to rtkpremium.xyz:2101 / COMMON). Then capture points. ### If the fix will not hold Mergin Maps / Input is QGIS-based and does NOT include a built-in NTRIP client. Corrections (rtkpremium.xyz / 2101 / COMMON / NTRIP) are configured on the GNSS receiver or its companion/NTRIP-client app - Mergin only consumes the corrected position over Bluetooth. Enter YOUR OWN NTRIP username/password into the receiver/app; never type them into Mergin Maps. UI labels (Manage GPS receivers, Connect new receiver, GPS accuracy button) vary slightly by version/platform. A FIXED solution on the receiver is required for cm accuracy. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # QField Set up QField on Android or iOS to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution. These steps set up QField on Android or iOS to receive RTK Premium corrections over NTRIP from an external GNSS receiver. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=qfield) to get your credentials. * QField app. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Have your NTRIP login ready: You'll need the per-customer NTRIP username and password from your welcome email. Enter YOUR OWN credentials at the NTRIP step - do not use anyone else's. The caster details (host, port, mountpoint) are the same for all customers. 2. Pair the GNSS receiver to your phone/tablet: Power on your external receiver (e.g. u-blox/ArduSimple or Emlid). Android: pair the receiver in system Bluetooth settings before opening QField. iOS: many receivers connect over Wi-Fi/TCP instead (e.g. via ArduSimple's WiFi NTRIP Master) - connect your device to the receiver's Wi-Fi. Pairing names vary by receiver. 3. Open Positioning settings in QField: Tap the GNSS/position button (top-left), then the gear/settings icon, and go to Settings > Positioning. The Positioning section is consistent across recent versions, though icon styling varies. 4. Add your external receiver as the position source: Add your receiver to the saved positioning devices: choose your paired Bluetooth receiver, or for a network/Wi-Fi receiver add a TCP/UDP connection (enter the receiver's IP and port - e.g. 192.168.4.1 for an ArduSimple WiFi NTRIP Master). Save it. 5. Activate the receiver: Toggle the switch next to your saved receiver to make it the active position source. QField should show a position from the external receiver rather than the phone GPS. 6. Open the NTRIP / correction-data settings: Next to the active device's toggle, tap its settings/gear button and open the NTRIP (RTK correction) configuration ('NTRIP Service information'). Note: depending on receiver and version, the NTRIP client runs inside QField or must be configured on the receiver itself (or its companion app/web page, e.g. a WiFi NTRIP Master at 192.168.4.1). If you don't see NTRIP fields in QField, configure them on the receiver - the same caster values apply. 7. Enter the caster host and port: Set host/server to rtkpremium.xyz and port to 2101. Labels are commonly 'Host'/'Address' and 'Port'; wording varies slightly by version but these map to the caster address and its port. 8. Enter YOUR NTRIP username and password: Enter the NTRIP credentials from your welcome email - unique to your account; the guide cannot supply them. 9. Select the mountpoint: Set the mountpoint to COMMON. If QField (or your receiver) offers a 'Get/refresh source table' option, the list populates once host/port/credentials are correct - pick COMMON; otherwise type it. Set protocol to NTRIP. Save/confirm. 10. Start the correction stream: On the device row, tap the arrow/connect control to start NTRIP. QField shows incoming and outgoing arrows when the stream works. If it won't connect, re-check host, port, the mountpoint spelling (COMMON), and your credentials. 11. Turn on the accuracy / position display: In Positioning settings enable 'Show position information' and the accuracy indicator. QField then shows a coloured quality dot on the GNSS button - red/yellow/green - plus a position panel with current accuracy and fix quality. 12. Confirm an RTK fix and cm-level accuracy: Wait in open sky for the solution to converge. You're done when the panel reports an RTK fixed solution and \~1 - 2 cm horizontal accuracy with the quality dot green. Exact fix-type wording varies by version/receiver, but green + cm accuracy confirms RTK works. ### If the fix will not hold QField needs internet (mobile data or Wi-Fi) to pull corrections. Behaviour varies by setup: on some receivers QField's own NTRIP client streams the corrections; on others (common on iOS, and with ArduSimple WiFi NTRIP Master) the NTRIP login is entered on the receiver or its companion app instead - the same caster values apply either way. Screen/button names differ between versions - match the nearest equivalent. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # SuperSurv (Android) Set up SuperSurv on Android to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution.

In Android Settings > Bluetooth, scan for and pair the receiver - SuperSurv requires Bluetooth to be on and pairing already done before it can use the device. Make sure the tablet also has internet (Wi-Fi or mobile data) to reach the caster. 2. Open GPS Settings in SuperSurv: Launch SuperSurv and open the 'GPS Settings' menu. By default it uses the device's Internal GPS; this is where you switch to your external receiver and configure corrections. 3. Select your external receiver as the signal source: In GPS Settings, use the 'Signal Source' drop-down to select your paired Bluetooth receiver instead of Internal GPS. For device type, choose your receiver's brand if listed (e.g. U-Blox, Hemisphere, NovAtel); otherwise choose 'General Device', which works with any receiver outputting standard NMEA. 4. Connect over Bluetooth: Confirm the Bluetooth connection to the selected receiver. The GPS status bar at the top of the map should show live position from the external receiver. If nothing appears, re-check the Android pairing and that the correct device is chosen in Signal Source. 5. Open the NTRIP / correction settings: Still in GPS Settings, go to the NTRIP service section (correction-source settings) - where you enter the caster so SuperSurv can pull RTCM corrections and forward them to your receiver over Bluetooth. 6. Enter the caster host and port: Host (IP/server) = rtkpremium.xyz, Port = 2101, Protocol = NTRIP - the same for every customer. 7. Enter YOUR NTRIP username and password: Type the NTRIP username and password from your welcome email into the username/password fields - unique to your account, case-sensitive; do not share or use anyone else's. If lost, contact support. 8. Get the mountpoint list: Tap the 'Get MountPoint' button. SuperSurv connects to the caster and retrieves the source table - confirming host, port and credentials are correct. If it fails to load, re-check host/port and re-type your credentials. 9. Select the COMMON mountpoint: From the retrieved list select 'COMMON' - the mountpoint used for all Premium Positioning customers. Apply/confirm. 10. Turn on the NTRIP service: Enable the NTRIP service. SuperSurv receives RTCM corrections over the internet and forwards them to your receiver via Bluetooth, where the module applies them. 11. Confirm a Fixed, centimetre-level solution: Watch the solution-type indicator at the top of the map. It should progress autonomous → differential/float → Fixed (RTK). Wait until it reports Fixed at cm-level before collecting points. If it stays on Float, allow more time with clear sky; if it never moves past autonomous, re-check that the NTRIP service is on and COMMON and your credentials are correct. ### If the fix will not hold Verified against SuperGeo's official SuperSurv docs for the labels 'GPS Settings', the 'Signal Source' drop-down, the 'General Device' option, the IP/Port fields, the 'Get MountPoint' button, and the NTRIP service toggle. Username/password field labels vary slightly by SuperSurv version - enter them in the NTRIP credential fields. SuperSurv acts as the NTRIP client and relays corrections to the receiver over Bluetooth, so both internet and a stable Bluetooth link are required.

These steps set up SW Maps on Android to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=sw-maps-android) to get your credentials. * SW Maps app. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Install SW Maps and gather your details: Install SW Maps (by Softwel) from Google Play. Have your Premium Positioning NTRIP username/password ready. SW Maps is a free, brand-agnostic app that works with most Bluetooth GNSS receivers (Emlid, ArduSimple/u-blox ZED-F9P, SparkFun, and many commercial receivers). 2. Power on and pair your receiver: Turn on your receiver and put it in Bluetooth pairing mode per its manual. In Android Settings > Bluetooth, scan and pair the receiver once (some ask for a PIN such as 0000 or 1234). SW Maps connects to the already-paired device. 3. Open the side menu in SW Maps: Launch SW Maps, create/open a project if prompted, and tap the menu icon (three lines) at top-left - this is where connection options live. Wording varies slightly by version. 4. Open Bluetooth GNSS Connection: In the side menu tap 'Bluetooth GNSS' (sometimes 'Connect Instrument', or a Bluetooth icon in the toolbar) to open the receiver-connection screen. 5. Select your receiver and set instrument details: Choose your receiver from the paired list. Set 'Instrument Model' to match, or pick a generic option ('Generic NMEA' / 'Generic RTK Receiver'). Enter 'Instrument Height' (pole/tripod height incl. antenna offset). Tap 'CONNECT'. 6. Confirm the receiver is streaming: The status bar should show live coordinates and satellite counts from the external receiver (metre-level before corrections). If you still see phone-GPS accuracy, recheck the Bluetooth selection and instrument model. 7. Open the NTRIP Client: Open the side menu and tap 'NTRIP Client' ('NTRIP Connection' in some versions). 8. Add a new NTRIP profile: Tap 'Add New Profile' or '+' and name it (e.g. 'Premium Positioning'). A saved profile lets you reconnect quickly next time. 9. Enter the caster address and port: 'NTRIP Caster Address': rtkpremium.xyz - 'NTRIP Port': 2101. Leave the protocol as NTRIP (NTRIP v1) - SW Maps connects over NTRIP by default. 10. Enter YOUR username and password: In 'User Name' and 'Password' enter the personal NTRIP credentials from your welcome email - unique to your account. If login fails, check for stray spaces or capitalisation. 11. Fetch and select the mountpoint: Tap the mountpoint field (or a fetch/refresh/dropdown control) so SW Maps loads the mountpoint list, then select 'COMMON'. If it doesn't load, double-check address, port, username and password and retry. 12. Turn on Send NMEA GGA to Caster: Enable 'Send NMEA GGA to NTRIP Caster' - this sends your approximate position to the network so it can compute corrections. Leaving it off can keep you stuck on FLOAT. 13. Connect to the caster: Tap 'CONNECT' (or 'Start'). The received-bytes/data counter should increase, confirming corrections are flowing from rtkpremium.xyz to your receiver. 14. Confirm an RTK FIXED solution: Open the side menu and tap 'GNSS Status' (or 'Skyplot') to watch the fix type move Single/DGPS → RTK Float → RTK Fixed, with accuracy \~1 - 3 cm. The location marker also turns green at a fix. You're ready to collect points. ### If the fix will not hold SW Maps is brand-agnostic and works with most Bluetooth GNSS receivers. Menu/field names vary slightly between versions/devices - if something is worded differently, find the equivalent ('NTRIP Client' vs 'NTRIP Connection', 'CONNECT' vs 'Start'). Your username/password are personal and typed into the app only. A clear sky view and stable mobile data give the fastest, most reliable fix. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Topcon Magnet Field Set up Topcon MAGNET Field with a HiPer VR or HiPer HR to receive RTK Premium corrections over NTRIP: caster settings and the steps to a fixed solution. These steps set up Topcon MAGNET Field on an FC-series controller to receive RTK Premium corrections over NTRIP with a HiPer VR or HiPer HR. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=topcon-magnet-field) to get your credentials. * MAGNET Field (FC-series controller). * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair the receiver: Switch on the HiPer VR / HR and the FC-series controller (FC-500 / FC-5000), open MAGNET Field, and open or create a job. On the Bluetooth/connection screen make sure the FC is paired with this receiver's serial number. Confirm a working SIM or Wi-Fi in the FC - on an FC-series controller the corrections arrive over the controller, not the receiver's own modem. 2. Open the configuration list: Tap Configure, then Survey (or Configurations) to reach the list of survey configurations. Highlight an existing Network RTK configuration and tap the edit (pencil) icon, or create a new one. Move through pages with the Next/arrow button. 3. Set the survey type to Network RTK: On the first page set Type = Network RTK and Corrections = VRS (the normal choice for a single-mountpoint caster). Rename the configuration here if you like, e.g. 'Premium Positioning'. Tap Next. 4. Configure the Rover Receiver: Set Receiver Model to HiPer VR or HiPer HR (whichever you own) and Protocol = NTRIP. Set Antenna to match, enter the Antenna Height (default 2.000 m) and measurement method, and an elevation mask (commonly 10 - 13°). Leave Simulation Mode unchecked. Tap Next. 5. Set the modem (data-collector internet): Set Modem Connect = Controller (sometimes 'Data Collector') so MAGNET sends corrections over the FC controller's cellular/Wi-Fi rather than an internal receiver modem - correct for the HiPer VR/HR on an FC-500/FC-5000. Tap Next. 6. Enter the NTRIP caster address and port: On the network / internet-info page enter Server / Host: rtkpremium.xyz and Port: 2101. If there's an IP-vs-Web toggle choose Web/host name; if the page uses a single field, enter rtkpremium.xyz:2101. Tap Next. 7. Enter YOUR NTRIP username and password: Enter the NTRIP user ID and password from your Premium Positioning welcome email (case-sensitive, unique to your account). Tap Next. The credentials live only in this configuration on the controller and are only sent to the caster at sign-on. 8. Set the solution type to Fixed Only: On the Topo Survey Parameters page set Solution Type = Fixed Only for the Precise and Quick measurement buttons, and apply the same on the Stake settings page. Set epochs to average and tolerances to taste. Tap through the remaining pages. 9. Check the Advanced tab: Leave special options unchecked for standard network RTK. Satellite system GPS+GLONASS (or add Galileo/BeiDou - the HiPer VR/HR are multi-constellation), RTK Position = Extrapolation, Base Station Make = Automatic Detection. Save the configuration. 10. Connect and load the mount-point list: With the configuration selected, tap the connect icon to dial the caster. MAGNET requests the source table; if you see 'no mount point to connect to automatically, please select one', tap the drop-down to view the available streams. 11. Select the COMMON mount point: From the source-table drop-down, select COMMON. If the list is empty, the host/port/credentials are usually the cause - re-check rtkpremium.xyz, port 2101, and your username/password. 12. Confirm corrections are flowing: After your credentials verify you should see a 'Data received' message and the age-of-corrections indicator counting low (e.g. 1 - 2 s). An authorisation error means wrong credentials; connected-but-no-data means re-check the COMMON mount point. 13. Start the survey and confirm a Fixed solution: Tap Survey > Topo to open the measurement screen. The solution status progresses Autonomous → Float → Fixed. Wait for FIXED with good precision before storing points. If it stays Float, check sky visibility, age of corrections, and that the mount point is COMMON. ### If the fix will not hold Icons, labels and page order vary slightly between MAGNET Field versions and between the FC-500 and FC-5000, but the sequence is the same. Key choices for the HiPer VR/HR on an FC-series controller: Protocol = NTRIP, Modem Connect = Controller. If no streams appear or you can't reach Fixed, re-check host/port/credentials, confirm the controller has live internet, and that the receiver is paired over Bluetooth. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps set up Trimble Penmap for Android, with Trimble Mobile Manager, to receive RTK Premium corrections over NTRIP. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-penmap-for-android) to get your credentials. * Trimble Penmap (Android) / Trimble Mobile Manager. * A working internet connection on the controller or phone. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Before you start: Have your tablet/phone online (Wi-Fi or SIM data) and your Trimble GNSS receiver charged and paired over Bluetooth. NTRIP corrections come over the internet. Keep your welcome email handy - it has YOUR personal NTRIP username and password. 2. Pick where corrections are configured: On an R-series receiver (R2/R8/R10/R12), set the NTRIP source inside Penmap (next steps). On a Catalyst DA2, the source is normally set in Trimble Mobile Manager (TMM) and Penmap uses 'Trimble Corrections Hub' - see the DA2 step at the end. If unsure, try the Penmap path first. 3. Open GNSS settings in Penmap: In Penmap, touch-and-hold the GNSS button and tap the settings icon, or open the map menu and choose 'GNSS'. Wording varies slightly by version - look for 'GNSS'. 4. Select your GNSS receiver: In 'GNSS receiver', set Manufacturer to Trimble, then choose Model and Connection (typically Bluetooth) so Penmap connects. Tap 'Info' to confirm it's connected. 5. Add a real-time correction source: Go to 'Real-time corrections' and create/edit a source. Enter a Service Name you'll recognise (e.g. 'Premium Positioning'). 6. Choose NTRIP as the service type: In 'Service Type' select 'NTRIP', then tap 'Next'. 7. Enter the Premium Positioning caster: Enter the caster manually rather than from the Caster Name drop-down: server/address rtkpremium.xyz, Port 2101. (Depending on version the address field may read 'IP Address' or 'Caster Name' - enter rtkpremium.xyz there.) 8. Select the COMMON mount point: Tap 'Select stream' (the mount point / source-table list) and choose 'COMMON'. If it won't load, recheck rtkpremium.xyz and port 2101, then retry - the list is pulled live. 9. Enter YOUR NTRIP credentials: When prompted for user name and password, enter the personal NTRIP credentials from your welcome email - unique to your account; do not use anyone else's. Tap 'OK' to save the source. 10. Start corrections and check the GNSS badge: On the map, the GNSS/correction button turns green when corrections are received from your NTRIP stream. Green means data from Premium Positioning is reaching the receiver. Red means none arriving - recheck data connection, caster, mount point and credentials. 11. Confirm a fixed, centimetre solution: Wait for the receiver to converge. Penmap shows position quality on the GNSS button (satellite count, estimated accuracy) and the on-map cursor turns green within your quality limits. A fixed RTK solution shows \~1 - 3 cm estimated accuracy. Don't record points until accuracy is within tolerance. (Penmap reports quality via the badge/cursor and accuracy figure rather than the literal words 'RTK Fixed'.) 12. Catalyst DA2: set NTRIP in Trimble Mobile Manager: For a Catalyst DA2, open Trimble Mobile Manager (TMM), choose a local/external NTRIP service, and enter server rtkpremium.xyz, port 2101, mount point COMMON, and YOUR welcome-email credentials. Save, then in Penmap select 'Trimble Corrections Hub' as the real-time corrections service. (TMM's field labels vary by version - look for the NTRIP/correction-source screen.) ### If the fix will not hold R-series receivers: configure NTRIP inside Penmap. Catalyst DA2: configure NTRIP in Trimble Mobile Manager, then select Trimble Corrections Hub in Penmap. Screen/field names differ between Penmap/TMM versions - match by meaning. A fixed solution is confirmed by a green GNSS badge/cursor and cm-level estimated accuracy rather than a literal 'RTK Fixed' label.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and ensure internet: Switch on the iCG70 and the tablet, and make sure the tablet has a working internet connection (SIM data, tablet Wi-Fi, or a phone paired over Bluetooth). The rover pulls corrections over this connection, so confirm it is online before starting. 2. Open the GNSS connection wizard: In the Leica iCON field software, go to the instrument/connection area, tap the Communication Mode container, then tap Mode to start a new connection. (On a CS20 in Leica Captivate the equivalent path is Home > Settings > Connections > RTK rover.) 3. Connect to the iCG70 receiver: Choose the connection type to the receiver (usually Bluetooth), search, and select your iCG70 / iCG70 T from the results - it normally appears by its serial number. Let the controller finish pairing. 4. Create a new configuration: At the configuration/antenna screen choose New Configuration (rather than an existing profile) so you can define a fresh NTRIP network-rover profile. 5. Set the basic sensor settings: In Basic Settings set Sensor mode to Rover, Use to Network, and Connect via to NTRIP. These three choices tell the iCG70 to receive RTK corrections from an NTRIP caster over the internet. 6. Choose the internet connection: When prompted for the device that provides internet, select the tablet/receiver internet (GSM/SIM, Wi-Fi, or the paired phone) and create/enable it if no profile exists yet. Exact wording of this sub-screen varies by iCON version - pick the option that uses the controller's own internet, not a radio. 7. Enter the Premium Positioning caster: In the NTRIP connection (server) settings enter Server / Host: rtkpremium.xyz and Port: 2101. Leave the protocol as NTRIP. 8. Enter YOUR NTRIP credentials: Enter the NTRIP User ID and Password from your Premium Positioning welcome email. These are unique to your account - type your own; do not use example values. 9. Download / refresh the source table: Trigger the source-table retrieval - the field software downloads the available mountpoints once the caster details and credentials are correct. An empty list usually means a wrong server/port, bad credentials, or no internet. 10. Select the COMMON mountpoint: From the downloaded mountpoint (source table) list, select the mountpoint named COMMON. This is the Premium Positioning correction stream for your rover. 11. Enable Send GGA position: Set Send GGA (auto-position / send user position) to On or Automatic so the network can generate corrections for your location. If asked for a network type, VRS or iMAX is typical depending on your region. 12. Set the antenna and pole height: In the antenna settings select the iCG70 antenna and enter your exact pole height (e.g. 2.000 m). An incorrect pole height directly biases your measured heights. 13. Save and start the profile: Name the profile (e.g. Premium Positioning RTK), save it, then tap it to start. The controller connects to the internet, then the NTRIP caster, and the solution should progress Single > Float > Fixed. 14. Confirm RTK Fixed: Verify the solution status shows Fixed with low, stable coordinate quality before measuring. If it stays Float, recheck Send GGA, the COMMON mountpoint, your credentials, and your internet signal. ### If the fix will not hold Screen and button labels differ between iCON field-software versions and Leica Captivate (CS20); the Basic Settings (Rover / Network / NTRIP), caster fields and mountpoint selection are consistent, but the internet-connection sub-screen wording varies - follow the option that uses the controller's own internet. The iCG70 usually gets internet via a Bluetooth-paired phone, the tablet's Wi-Fi, or an internal SIM. Choose VRS or iMAX network type per your region if prompted.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get the controller online first: Network RTK needs a live internet connection on the data collector. Before opening Pocket-3D, connect the controller to the internet via its SIM/data plan or a phone hotspot. Without data the NTRIP login fails. Have your NTRIP username/password (from your welcome email) ready. 2. Open Equipment setup: In Pocket-3D tap Setup, then Equipment. Tap New (or edit an existing config). Name it e.g. 'PP Network RTK'. Set Machine type to Range pole, Sensor to GNSS, Mounting location to Top of pole, Units as required, then Next. 3. Confirm the antenna page: Set Antenna type to match your Topcon receiver (e.g. HiPer VR), enter your Antenna height, and set Measured to for your pole. Set Connection (Pocket-3D) to how the controller talks to the receiver (Bluetooth for wireless). Tap Next. 4. Choose a network correction source: On the radio page, change Radio type to Direct Network Connection (switches from UHF radio to NTRIP over the internet). Connected to shows Virtual Port A. Leave Baud Rate at 115200 and set Format to RTCM 3.x. 5. Set the caster server address and port: Tap Set next to Base IP/port and enter the caster as host then port - Host: rtkpremium.xyz, Port: 2101 (typically entered as rtkpremium.xyz/2101 or rtkpremium.xyz:2101). Tap Ok. 6. Open the NTRIP / Network Corrections dialog: Back on the radio page tap NET to open the Network Corrections (NTRIP) dialog. NTRIP Server should read rtkpremium.xyz with port 2101 from the previous step - confirm it, or type it if blank. 7. Enter YOUR NTRIP username and password: In NTRIP Username and NTRIP Password type the credentials from your welcome email, case-sensitive, no extra spaces. Unique to your account; do not share them. 8. Select the mountpoint: In Mount-point, select or type COMMON - the fixed Premium Positioning stream. If the dropdown can pull the source table, COMMON should appear once the login details are correct. 9. Set the network type and confirm: Set Network type to match the service (typically VRS for a single-mountpoint network RTK). Tap Ok to close the NTRIP dialog, then Next and Finish to save the configuration file. 10. Make this configuration current: Go to Setup > Equipment, highlight your new network config, and tap Ok. When prompted to set it as the current equipment, tap Yes. 11. Connect the rover: Go to Survey > Connect, select your Rover (receiver), and tap Ok. Pocket-3D connects to the receiver, logs in to rtkpremium.xyz:2101 on COMMON with your credentials, and streams RTCM 3.x corrections. 12. Confirm a Fixed solution: Watch the GNSS status: the Base Station and Rover icons (bottom-left) should turn green and the solution should report Fixed (not Float/Autonomous). A Fixed solution with cm precision means you're connected and ready. If it stays Float, check internet, that the username/password are exact, and that the mountpoint is COMMON. ### If the fix will not hold Screen/button labels in Pocket-3D / 3D-MC vary by version: this guide follows the standard network-RTK flow (Setup > Equipment > radio page set to 'Direct Network Connection' > NET > NTRIP dialog). Where a label differs, look for the equivalent NTRIP / Network Corrections fields. For a single-mountpoint network, 'Network type' is usually VRS.

These steps connect a Trimble Earthworks grade-control system to the Premium Positioning correction network over an internet NTRIP connection. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-earthworks) to get your credentials. * An Earthworks display with a working internet connection. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-earthworks#iot-sims) give it its own data connection. * The GNSS receiver configured for internet corrections. * A clear view of the sky at the machine. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Open the correction source settings: In Earthworks, open the correction source settings. 2. Choose Internet (NTRIP): Select 'Internet (NTRIP)' as the correction method. 3. Create an NTRIP profile: Create a new NTRIP profile and enter rtkpremium.xyz as the server and 2101 as the port. 4. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account. 5. Select the mountpoint: Load the source table and select COMMON. 6. Set the correction format: If the profile asks for a correction format or network type, choose RTCM 3.x and VRS. 7. Apply and confirm RTK Fixed: Apply the profile and check that the system reaches 'RTK Fixed' before you start grading. ### If the fix will not hold Earthworks versions and platforms, such as the EC520 and EC550, differ, so the correction-settings path on your machine may not match these labels exactly. The display needs a live internet connection while the machine works. If the source table will not load, recheck the server, the port and your credentials. If the system stays below RTK Fixed, confirm that COMMON is selected and that the receiver is set for internet corrections. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Trimble SPS986 to the Premium Positioning correction network over NTRIP, using Trimble Siteworks. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-sps986) to get your credentials. * Trimble Siteworks. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-sps986#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and connect the receiver: Switch on the SPS986 and your tablet/controller (TSC7, TCU5, T7, etc.). Open Trimble Siteworks. From Home tap Project Setup > Connect Device > GNSS. If you don't see these names, look for the equivalent 'Connect Device' / 'GNSS receiver' option. 2. Pair the SPS986 with the tablet: On the GNSS setup screen choose the connection type (Bluetooth is most common; Cable also works). For Bluetooth, select the SPS986 from the list and confirm pairing so Siteworks shows it connected. 3. Set the receiver Mode to Rover: On the GNSS configuration screen set Mode to Rover so the SPS986 receives corrections rather than broadcasting them. 4. Choose the internet correction method: Set Correction Method to the internet/network option - in current Siteworks this is 'Internet (VRS)'. Wording differs by version ('Internet', 'NTRIP', or 'VRS'); pick the option that streams RTK over the controller's internet rather than Radio or RTX. The tablet must have data (SIM or Wi-Fi). 5. Confirm the internet source: If prompted for the GNSS internet source, select the controller's own internet connection (e.g. 'Controller internet'). 6. Create a new correction profile (GNSS Contact): Siteworks stores caster settings as a saved correction profile (a 'GNSS Contact'). Tap New / Add to create one, name it e.g. 'Premium Positioning'. 7. Enter the caster server address and port: Server/address: rtkpremium.xyz - Port: 2101. Leave any TLS/SSL switch off unless told otherwise. 8. Enter YOUR NTRIP username and password: In the NTRIP username and password fields, type the credentials from your Premium Positioning welcome email - unique to your account; do not use anyone else's. 9. Set the mount point to COMMON: Enter COMMON (capitals) in the Mountpoint field. If Siteworks offers a 'Get mount points' button instead, tap it to pull the list from the caster and choose COMMON. 10. Save the correction profile: Tap Accept / OK / Store to save the GNSS Contact for reuse. 11. Set the antenna height: When prompted, enter the Antenna height (your pole height, e.g. 2.000 m) and the correct measurement method, then Accept. Accurate height is essential for correct elevations. 12. Start the survey / connect: Finish the wizard (Accept / Connect / Start Survey). Siteworks connects to the caster over the internet and requests corrections. If a mount point list appears, confirm COMMON. 13. Confirm an RTK Fixed solution: Watch the GNSS status indicator at the top progress from Autonomous/Float to RTK Fixed (cm-level precision), usually within a minute or two. If it stays Float or won't connect, recheck rtkpremium.xyz / 2101 / COMMON, your credentials, and that the tablet has internet. ### If the fix will not hold Exact screen/field names vary slightly between Siteworks versions and controllers (TSC7, TCU5, T7); use the closest equivalent. The SPS986 also supports IMU tilt compensation - optional and separate from correction setup. If you can't reach RTK Fixed, the most common causes are a typo in the host/credentials or no mobile data on the tablet.

These steps connect an Ag Leader InCommand (GPS 6500 / SteerCommand) to the Premium Positioning correction network over NTRIP, using InCommand display. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=ag-leader-incommand-gps-6500) to get your credentials. * InCommand display. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=ag-leader-incommand-gps-6500#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get an internet connection in the cab first: NTRIP reaches the display over the internet, so the InCommand must be online: a built-in/connected cellular modem (e.g. InCommand Go) with a data plan, or an Ag Leader Relay (CDMA/GSM) paired to the GPS 6500. Confirm signal before continuing. The cellular/relay status wording varies by display/firmware. 2. Open Setup: From the main run screen, tap the Setup icon (the red square with a wrench). 3. Go to the GPS/Guidance Setup tab: Tap the GPS/Guidance Setup tab (GPS/steering-wheel icon). The GPS/Guidance Setup window opens with Steering, Receiver, and other options. 4. Open the receiver's GPS Settings: Under the Receiver drop-down (often 'Autodetect' or your GPS 6500), tap the wrench icon to its right. The GPS Settings dialog opens with tabs such as General, Port A, Port B. 5. Set the Differential Source to RTK External: On General, open the Differential Source drop-down (may read 'WAAS/EGNOS') and select 'RTK External' so the GPS 6500 takes RTK from the display's NTRIP client. Tap the Go Back arrow to return. 6. Open the NTRIP client: On GPS/Guidance Setup, tap the 'Ag Leader NTRIP Setup' button. The NTRIP Client Settings dialog opens with Profiles on the left and Active Connection on the right. 7. Confirm the data connection (Networking): In NTRIP Client Settings, tap 'Networking' to confirm the display is using your cellular/relay connection. The NTRIP client needs this link active to log in. (Label/flow varies by firmware.) 8. Create a new NTRIP profile: In the Profiles list tap the Plus (+) icon to add a profile, then select it to open NTRIP Profile Settings. 9. Enter the caster Server and Port: In the Server field enter host and port together: rtkpremium.xyz:2101 (Host rtkpremium.xyz, Port 2101). Protocol is NTRIP. Name the profile anything (e.g. 'Premium Positioning'). Leave Baud Rate at its default unless told otherwise. 10. Select the mountpoint / stream: In the Streams list, select the COMMON mountpoint. If it isn't shown, refresh/download the source table from the caster so it appears. (Ag Leader sometimes shows format names like RTCM3 - pick the COMMON entry; if prompted for a format and unsure, RTCM 3 / RTK-RTCM31 is the safe default for the GPS 6500.) 11. Enter YOUR NTRIP username and password: In Username and Password type the credentials from your welcome email - unique to you; entered into the display only and not stored on our servers. 12. Save the profile: Tap the green Check Mark to save. Use Cancel (X) only to discard. 13. Connect to the caster: Select your profile and tap 'Connect'. The Active Connection Status should change from 'Disconnected' to connected and show the Server and Stream. If login fails, re-check the Server/port, COMMON, and your credentials for typos. 14. Confirm RTK Fixed: Return to the run/guidance screen. Within \~a minute the GPS indicator should report a full RTK fix ('RTK Fixed', 'RTK', or a green GPS icon - varies by display/firmware). Once RTK Fixed you have sub-inch correction. If it sits on a lower-accuracy mode, confirm the cellular/relay link is up and the profile is Connected. ### If the fix will not hold The GPS 6500 must have RTK/NTRIP capability enabled (an RTK unlock) for 'RTK External' and sub-inch correction; if 'RTK External' is missing or you can't fix, contact Premium Positioning. Button/status labels vary by InCommand model (800/1200) and firmware - use the nearest matching option. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Open the NTRIP client in AgIO: Start AgIO and open its NTRIP client settings. 2. Enter the caster address and port: Set the caster to rtkpremium.xyz and the port to 2101. 3. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account. 4. Set the mountpoint: Enter COMMON as the mountpoint. 5. Turn on Send GGA: Enable 'Send GGA' so the network receives your approximate position. 6. Start the NTRIP client: Start the client. AgIO forwards the correction stream to your GPS board. 7. Confirm RTK Fixed: Check that AgOpenGPS reports 'RTK Fixed' before you start guidance. ### If the fix will not hold AgIO field labels vary between AgOpenGPS versions, so match the nearest equivalent in your build. AgIO needs a live internet connection for the whole session. If the solution stays at float or single, check that Send GGA is on, then recheck the caster address, the port, the COMMON mountpoint and your credentials. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Case IH AFS Pro / New Holland IntelliView (FM-750 / NAV-900) to the Premium Positioning correction network over NTRIP, using AFS Pro / IntelliView. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=case-ih-afs-pro-new-holland-intelliview) to get your credentials. * AFS Pro / IntelliView. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=case-ih-afs-pro-new-holland-intelliview#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Have your PP credentials and a data connection ready: Find the NTRIP username and password from your Premium Positioning welcome email - you'll type your own; we never supply them here. NTRIP corrections arrive over the internet, so the display needs a live data link: the machine's built-in cellular modem with an active SIM (e.g. DCM-300/Ag3000-class or the receiver's integrated modem) or a configured Wi-Fi connection. Confirm signal before continuing. 2. Power up and open the GPS / GNSS setup: Start the display (Case IH AFS Pro 700/1200 or New Holland IntelliView IV/12) and let the receiver power on. Open the guidance/GPS setup: on Precision-IQ-style screens tap the GPS/GNSS tile then the edit (pencil) or wrench icon; on the classic AFS Pro 700 menu, go to the Toolbox/GPS setup. Wording varies by display/firmware - look for the GPS/GNSS or 'Correction' setup. 3. Set the correction type to RTK: Find the Correction Type (or Correction Source) selector and choose RTK. On the AFS Pro 700 you press the Correction Type window, select RTK, and acknowledge the confirmation pop-up. This tells the receiver to expect cm-level corrections rather than a free/SBAS signal. 4. Choose Internet / NTRIP as the RTK delivery method: In the correction (RTK source / 'Correction Level' / delivery) options, select the Internet/NTRIP/Cellular option rather than Radio. Depending on display/receiver this may read 'Internet', 'NTRIP', 'Modem (DCM-300/Ag3000)', 'Cellular RTK', or 'VRS'. Pick the one that streams over the internet, not the radio option. 5. Confirm the display's internet connection: If prompted, select the data link for corrections: the internal cellular modem/SIM or a saved Wi-Fi network. Wait until the display shows it is online - NTRIP cannot connect without internet, so resolve any 'no connection / no SIM' warning before entering server details. 6. Enter the NTRIP server (caster) address: In the NTRIP server / caster address (or host/IP) field, enter: rtkpremium.xyz 7. Enter the port: In the Port (IP port) field, enter: 2101 8. Enter your NTRIP username and password: In the NTRIP Username and NTRIP Password fields, type YOUR OWN credentials from the welcome email exactly (case-sensitive). Do not share or guess - if you don't have them, contact Premium Positioning support. 9. Connect and load the source (mountpoint) table: Confirm/connect so the display contacts the caster. Once connected it retrieves the source table (the mountpoint list). If it fails here, re-check the server, port, and that your username/password are correct. 10. Select the COMMON mountpoint: From the mountpoint / data source list, choose: COMMON (Protocol: NTRIP). If the display asks you to type the mountpoint name instead of picking from a list, enter COMMON exactly. 11. Allow position reporting (GGA) for the network: Premium Positioning's network is a Network RTK / VRS-style service, so the caster needs your approximate position. If the display offers 'Send GGA', 'Send position to caster', or a VRS option, make sure it's enabled. Most CNH/Trimble displays do this automatically once a GPS position is available - if you see zero correction data, confirm this setting. 12. Save and let the receiver converge: Save/apply and return to the run/guidance screen. The receiver receives corrections and converges, usually within a few seconds up to a couple of minutes outdoors with clear sky. 13. Confirm RTK Fixed: Check the GPS/accuracy status indicator. You're set up when it reports RTK Fixed ('RTK', 'Fixed', or the highest-accuracy indicator) with a stable, low-error reading. If it stays at 'Float', 'Converging', or a lower mode, verify internet signal, the COMMON mountpoint, and your credentials, then allow more time under open sky. ### If the fix will not hold Case IH AFS and New Holland IntelliView displays share Trimble-based correction software, so the NTRIP/Internet RTK workflow closely mirrors Trimble Precision-IQ and FmX/FM-750. Screen names, icons and the exact correction-source/internet wording differ by display model (AFS Pro 700 vs 1200, IntelliView IV vs 12) and firmware - follow the equivalent option. If you can't reach RTK Fixed: weak/absent cellular or Wi-Fi, a mistyped server/port/mountpoint, wrong/expired credentials, or GGA/VRS position reporting disabled.

If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=claas-gps-pilot#iot-sims) give it its own data connection. * A clear view of the sky where you are working. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Check the correction path: The path depends on your terminal model and firmware. If your terminal has no built-in NTRIP client, set up an NTRIP-capable modem to feed the receiver and enter the settings below in the modem instead. 2. Select NTRIP as the correction source: In the terminal's correction settings, select 'NTRIP' as the correction source. 3. Enter the caster address and port: Enter rtkpremium.xyz as the host and 2101 as the port. 4. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account. 5. Set the mountpoint: Enter COMMON as the mountpoint. 6. Confirm RTK Fixed before steering: Wait for the terminal to report 'RTK Fixed' before you engage steering. ### If the fix will not hold Menu labels and the correction path differ between CLAAS terminal models and firmware versions, so match the nearest equivalent on your terminal. The terminal or modem needs a live data connection while you work. If the solution will not reach or hold RTK Fixed, recheck the host, the port, the COMMON mountpoint and your credentials. If your setup offers an option to send GGA or position to the caster, keep it on, because the network uses your approximate position.

If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=fjdynamics-at2-at1-autosteer#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and sign in to the FJD display: Start the FJD autosteer terminal and log in with your FJDynamics account. The home screen shows status icons across the top: 4G/mobile signal, GNSS, and the correction-source (RTK) signal. Note: your FJD account login is separate from the NTRIP login you'll enter later. 2. Make sure the display has a working data connection: Network RTK comes over the internet, so the terminal needs live mobile data. Confirm the 4G / mobile-signal icon is active (insert/activate the SIM, or connect Wi-Fi if supported). Without data, it reaches satellites but never goes to RTK Fixed. 3. Open the correction-source / RTK settings: Tap the RTK / correction-source icon in the status bar (or open it from settings). FJD offers three sources: Mobile Base Station (radio), Network RTK, and SBAS. Wording/icons vary slightly by firmware - look for the RTK or correction-source setup screen. 4. Choose Network RTK: The kit defaults to Mobile Base Station. Switch to 'Network RTK' (the internet/NTRIP mode for a CORS/NTRIP service) using the selector on the right. Do not select Mobile Base Station (radio) or SBAS. Once selected, Network RTK becomes the default next login. 5. Enable Network RTK and open the connection dialog: With Network RTK selected, enable it and tap 'Connect'. The 'Connect Network RTK' dialog appears with the NTRIP server (domain) and your NTRIP account. 6. Enter the caster Host and Port: Host: rtkpremium.xyz Port: 2101. The same for every customer. Type them exactly, no 'http\://', no spaces. 7. Tap 'Get Source' to load the mountpoint list: After Host and Port, tap 'Get Source'. The terminal pulls the source table and populates 'Source Node', auto-selecting the strongest match. 'Get Source' must succeed before you can connect - if it fails, recheck Host/Port and your data signal. 8. Set the Source Node (mountpoint) to COMMON: In 'Source Node', make sure COMMON is selected; if it auto-filled a different node, tap the field and pick COMMON. The protocol is standard NTRIP - selecting Network RTK with a valid source node is what tells the kit to use NTRIP. 9. Enter YOUR NTRIP username and password: In 'Account' enter YOUR NTRIP username, and in 'Password' your NTRIP password - the per-user credentials from your welcome email. Unique to your account; don't reuse your FJD app login here. 10. Tap 'Connect': With Host, Port, Source Node (COMMON), Account and Password filled, tap 'Connect'. Allow up to \~3 minutes for the first connection to establish and converge. 11. Confirm an RTK / Fixed solution: On the home screen the RTK signal bars should be full, 'RTK' shows in the upper-right (Network RTK mode), and in Real-time Status the RTK Status value reads 4 (Fixed). Then you can create guidance lines and autosteer. 12. If it won't connect or won't reach Fixed: Recheck: Host (rtkpremium.xyz) and Port (2101) typed exactly; Source Node is COMMON; your Account/Password match the welcome email (a wrong password is the most common cause); the 4G/data signal is present; and you have clear, open sky. FJD's Troubleshooting checklist flags weak 4G or an invalid NTRIP account as the usual culprits. ### If the fix will not hold Your NTRIP username/password come from your welcome email and are NOT your FJDynamics app login. The terminal needs live mobile-data (4G/SIM) or Wi-Fi for Network RTK. On-screen labels ('Network RTK', 'Get Source', 'Source Node', 'Account', 'RTK Status') are from current FJD AT2/AT1 manuals; menu names/icons vary by firmware - match the equivalent correction-source / RTK / NTRIP setting.

These steps connect a John Deere StarFire receiver to the Premium Positioning correction network over NTRIP. StarFire receivers have no built-in NTRIP client, so the corrections reach the receiver through an NTRIP-capable modem. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=john-deere-starfire) to get your credentials. * A StarFire 6000, 7000 or 7500 receiver. The SF1 and SF2 accuracy levels do not support RTK. * RTK and Mobile RTK activations on the receiver. Your John Deere dealer can confirm or add them. * An NTRIP-capable modem that delivers RTCM 3 corrections to the receiver's serial port. A John Deere modem works only where your dealer's configuration allows third-party networks, so confirm this with your dealer. * A data connection on the modem. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=john-deere-starfire#iot-sims) give it its own data connection. * A clear view of the sky where you are working. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Connect the modem: Connect the NTRIP modem to the receiver's serial port, following the modem maker's instructions, and check that the modem has a data connection. 2. Open the modem's NTRIP client settings. 3. Enter the caster address and port: Enter rtkpremium.xyz as the host and 2101 as the port. 4. Enter your NTRIP username and password: Type your own credentials exactly as they appear in your welcome email. They are case-sensitive and unique to your account. 5. Set the mountpoint: Enter COMMON as the mountpoint. 6. Turn on position sending: If the modem offers an option to send GGA or the receiver position to the caster, keep it on, because the network uses your approximate position. 7. Set the correction source on the display: In the StarFire settings on the display, select the third-party RTK correction source. Labels vary by display and firmware. 8. Confirm RTK Fixed before guidance: Wait for the display to report 'RTK Fixed' before you engage guidance. ### If the fix will not hold If the receiver does not accept corrections, check that the RTK and Mobile RTK activations show as active on the receiver status page, and that the modem's serial output matches the receiver's port settings. John Deere's own satellite RTK service, and a John Deere modem locked to John Deere's network, will not carry third-party corrections. Otherwise, check that the modem is online, then recheck the host, the port, the COMMON mountpoint and your credentials.

These steps connect a Raven RS1 / Viper 4+ to the Premium Positioning correction network over NTRIP, using Raven Slingshot / Viper. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=raven-rs1-viper-4%2B) to get your credentials. * Raven Slingshot / Viper. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=raven-rs1-viper-4%2B#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Confirm RTK is unlocked and you have your credentials: On Raven, NTRIP is delivered over a cellular link, so you need a Slingshot Field Hub (or another active cellular RTK relay) paired to the RS1, and the RS1 must have an RTK unlock. If RTK isn't unlocked, the RTK source screen shows 'RTK Is Not Unlocked'. Have your own NTRIP username/password (from your welcome email) ready - the network details below are the same for everyone. 2. Note the fixed Premium Positioning network details: Enter these exactly: Caster / Host: rtkpremium.xyz - Port: 2101 - Mountpoint: COMMON - Protocol: NTRIP. Identical for every customer; only your username and password are unique. 3. Confirm the Field Hub has cellular and a data connection: The Field Hub relays corrections over cellular, so it needs active data. If you use the Slingshot Field Hub Configurator (from the Raven portal), confirm cellular/APN, Wi-Fi and baud there. Labels vary by Configurator version - make sure the Field Hub reports it is online before continuing. 4. Open the Slingshot web portal: On Raven, the NTRIP/CORS network for a Field Hub is typically chosen in the password-protected Slingshot web portal, not typed on the display. Sign in to your Slingshot account and locate your Field Hub in the device list. Menu names vary by portal version - look for the Field Hub's RTK/correction configuration area. 5. Choose a custom / third-party NTRIP network: In the Field Hub's correction settings, select the option to use a custom/third-party RTK network (not a built-in Slingshot/CORS preset). The wording may be 'Custom', 'Third Party', 'NTRIP', etc. This exposes fields for the caster address, port, mountpoint and login. 6. Enter the caster server and port: Server/host (sometimes 'Caster' or 'IP/Address'): rtkpremium.xyz. Port: 2101. If the portal combines them, use rtkpremium.xyz:2101. 7. Select the mountpoint: In the Mountpoint (sometimes 'Mount Point' or 'Data Stream') field, enter or select COMMON. If the portal fetches a source table, pick COMMON from the list. 8. Enter YOUR NTRIP username and password: In Username and Password, enter the personal login from your welcome email - unique to your account; do not use anyone else's. Save/apply the settings in the portal. 9. Push the settings to the Field Hub over cellular: After saving, the Slingshot portal sends the new NTRIP configuration to your Field Hub over cellular. This can take a short time - wait for the portal (or Field Hub status) to confirm the settings were delivered. 10. Set the RS1 RTK source to Network: On the display (Viper 4/4+: typically Edit > GPS), open the GPS/RTK configuration. On the RTK source setting, the choices are usually 'Network' (Slingshot server / cellular), 'Serial', 'None', 'Auto'. Set it so the RS1 accepts Slingshot/network corrections - 'Network' (or leave 'Auto' if your setup is locked appropriately). If you only see 'Auto/Serial', your system may take corrections serially from the Field Hub - leave the locked setting as delivered. 11. Open the GPS Status / health screen: Go to the GPS status/messages screen to watch the correction state. Raven shows a convergence message ('Converging' then 'Converged') plus an 'Age of Differential' value. A low, steadily-updating Age of Differential confirms corrections are flowing. 12. Confirm an RTK Fixed solution: Wait for convergence. On Raven the GGA quality indicates the fix: 4 = RTK Fixed, 5 = RTK Float. You want RTK Fixed (mode 4) with status 'Converged' and a small, stable Age of Differential. If it stays at Float or 'Converging', recheck cellular signal, your credentials, and that COMMON / port 2101 / rtkpremium.xyz were entered exactly. ### If the fix will not hold Raven RS1 receives NTRIP over a cellular link via a Slingshot Field Hub (or equivalent), and the network is normally configured in the password-protected Slingshot web portal then pushed to the Field Hub - you usually don't type the caster details directly on the Viper display. RTK must be unlocked first. Confirm a true RTK Fixed (GGA mode 4 / 'Converged') before relying on accuracy. Menu names vary by display (Viper 4 vs 4+) and portal version. For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET. Contact us at or +31 85 0606 338, and include your receiver model, the mountpoint, the solution status, and the correction age. # Topcon X35 / XD+ (AGI-4 / AGS-2) Connect a Topcon X35 or XD+ display with an AGI-4 or AGS-2 receiver to RTK Premium corrections over NTRIP using Horizon: caster settings and the steps to a fixed solution. These steps connect a Topcon X35 / XD+ (AGI-4 / AGS-2) to the Premium Positioning correction network over NTRIP, using Horizon. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=topcon-x35-xd%2B-agi-4-ags-2) to get your credentials. * Horizon. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=topcon-x35-xd%2B-agi-4-ags-2#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Confirm your hardware is RTK-ready: On the X35 / XD+ console (Horizon) with an AGI-4 or AGS-2 receiver, Network RTK / NTRIP requires the receiver unlocked for RTK and a working internet connection (the AGI-4 normally needs the RTK/IMU unlock plus an internal cellular SIM or an approved Wi-Fi/cellular modem). If unsure your unit is RTK-enabled, check with Premium Positioning first. 2. Open the GPS Correction setup screen: From the Horizon home screen open the menu and go to System > GPS > Correction. This opens the GPS Correction Source screen (the GPS section is under System, correction options under it). 3. Set the Correction Source to RTK (NTRIP): Tap CORRECTION SOURCE and change it from Autonomous to RTK (NTRIP). Wording may read 'RTK', 'NTRIP' or 'RTK (NTRIP)' by firmware - choose the option for Network RTK over the internet (NTRIP). 4. Let the modem / connection wizard run: When RTK (NTRIP) is selected, Horizon runs a short wizard to detect the modem or cellular/Wi-Fi connection. Allow it to finish. If it can't find a connection, confirm your SIM/data plan or Wi-Fi modem is active, then retry. 5. Open the NTRIP Setup screen: After the wizard, Horizon shows the NTRIP Setup screen (also under System > GPS, NTRIP tab). Enter the caster details on the right, and (if using a receiver SIM) the GSM/APN details on the left. 6. Enter the NTRIP Address (caster host): Tap NTRIP ADDRESS and enter exactly: rtkpremium.xyz (no http\://, no spaces). Sometimes called the caster, server or end point. 7. Enter the NTRIP Port: Tap NTRIP PORT and enter: 2101 8. Enter the NTRIP Mount Point: Tap NTRIP MOUNT POINT and enter: COMMON (capitals). If your firmware can fetch the source table, select COMMON from the list. 9. Enter YOUR NTRIP Username: Tap NTRIP USERNAME and enter the username from your welcome email - your own personal login, case-sensitive. 10. Enter YOUR NTRIP Password: Tap NTRIP PASSWORD and enter the password from your welcome email, exactly (case-sensitive). Premium Positioning never sets these for you - they are unique to your account. 11. Set the cellular / data details if using a SIM: If the receiver connects through its own SIM rather than Wi-Fi, fill the GSM fields on the left (GSM APN is the key one - your carrier's APN; GSM USERNAME/PASSWORD/PIN only if required; ALLOW 3G/roaming as appropriate). If you connect via Wi-Fi or the console's data link, leave the GSM fields as they are. 12. Save and let the connection establish: Close the NTRIP Setup screen to save. Horizon dials the caster and starts streaming. The receiver needs a standalone position first to send its location, so give it clear sky and a minute or two. 13. Confirm an RTK Fixed solution: Check the GPS/correction status (the satellite/GPS icon in the top status bar, or System > GPS status). Wait until it reports RTK Fixed ('Fixed', 'RTK Fix' or 'RTK Integer') - cm-level accuracy. If it stays on 'Float', 'DGPS', 'Autonomous' or 'No correction', recheck the caster details, mount point, your username/password, and that you have live internet and open sky. ### If the fix will not hold Network RTK over NTRIP needs live internet on the receiver/console (cellular SIM, Wi-Fi or modem) and open sky. Menu wording, the correction-type label and the fix-status text differ slightly between Horizon firmware versions and between X35 and XD+ - if a label differs, choose the equivalent (Network RTK / NTRIP over the internet). For more, see [RTK corrections troubleshooting](/troubleshooting/rtk-corrections-troubleshooting) and [Inconsistent RTK accuracy on site](/troubleshooting/inconsistent-rtk-accuracy-on-site). ### Need help Support runs on business days from 09:00 CET to 17:00 ET.

These steps connect a Trimble GFX-350 / XCN-750 (Precision-IQ) to the Premium Positioning correction network over NTRIP, using Precision-IQ. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet? Start a [14-day free trial](https://www.premium-positioning.com/start-14-day-free-trial?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-gfx-350-xcn-750-precision-iq) to get your credentials. * Precision-IQ. * A working internet connection on the controller or phone. * No phone or hotspot in the field? If your controller or receiver takes a SIM, Premium Positioning [IoT SIMs](https://www.premium-positioning.com/products?utm_source=docs\&utm_medium=referral\&utm_campaign=docs\&utm_content=trimble-gfx-350-xcn-750-precision-iq#iot-sims) give it its own data connection. * A clear view of the sky at the point you are measuring. ### Network settings These are the same for every Premium Positioning customer. Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Get your Premium Positioning NTRIP credentials ready: You'll enter corrections details on the display, including a username and password unique to your account - find these in your Premium Positioning welcome email. Don't type anyone else's, and don't guess; if you can't find the email, contact Premium Positioning before continuing. 2. Get the display online (Wi-Fi or cellular modem): NTRIP corrections arrive over the internet, so the display needs a live data connection. From the launcher/Settings, open Wi-Fi Settings and join a hotspot or network, or make sure your connected cellular modem has data/signal. Confirm internet before going further. (Wording varies by display/firmware.) 3. Open the GNSS tile: On the Precision-IQ Home screen, tap the GNSS tile - it shows your current correction service and satellite status. By default the display ships set to Autonomous correction. 4. Tap Edit to open the GNSS Edit screen: On the GNSS details screen tap Edit. The Corrections option is selected by default - where you change the correction service. 5. Open the Correction Service list: Tap Correction Service (Correction Services on some firmware). A pop-up list of correction sources appears, with Autonomous selected by default. 6. Select RTK as the correction source: Tap RTK. (If your account is licensed for a network/VRS RTK product, you may instead pick a VRS option - the internet/NTRIP fields are entered the same way. RTK/VRS usually requires a licence/unlock on the controller; if RTK is greyed out or missing, contact Premium Positioning or your Trimble reseller.) 7. Choose Internet / NTRIP as the data source: After selecting RTK, open the RTK options and set the connection method/data source to the internet option (commonly Internet, NTRIP, or Cellular/Modem - not Radio). Exact wording and location vary by display/firmware; if you don't see it, look in the RTK setup/options sub-screen. 8. Enter the caster server address: In the server / host / IP address field, enter: rtkpremium.xyz (field may be labelled Server, Server Name, Host, NTRIP Server or IP Address). 9. Enter the port: In the Port field, enter: 2101 10. Enter your NTRIP username and password: In the username and password fields (often Name/User and Password), enter the per-customer NTRIP login from your welcome email - your own; never reuse another customer's or invent them. 11. Load the source table and select the mountpoint: After server, port and login are entered, the display retrieves the available mountpoints (source table). Select: COMMON. If the list doesn't populate, re-check the server, port, internet, and credentials, then retry. (Protocol is standard NTRIP - no extra setting normally needed.) 12. Save and return to Home: Confirm/apply the RTK settings, then tap Home. The display begins connecting and requesting corrections; allow a short time for the stream to start. 13. Confirm RTK Fixed: Open the GNSS tile (or the status-bar correction indicator) and confirm the status reads RTK Fixed (not Float/DGPS/Autonomous), with a green GNSS status - cm-level corrections are live. If it stays Float or won't fix, recheck internet/data signal, the server/port/mountpoint, and your credentials; contact support if it persists. ### If the fix will not hold Exact on-screen labels (Correction Service vs Correction Services, Server vs Host vs IP Address, and the Radio-vs-Internet/NTRIP data-source toggle) differ between the GFX-350, XCN-750 and other displays and across Precision-IQ firmware - match the closest field on your screen. RTK/VRS usually requires a licence/unlock on the NAV-500/NAV-900 controller; if RTK is unavailable, contact Premium Positioning or your Trimble reseller.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Have your details ready: You need your personal NTRIP username and password (from your PP welcome email) plus a working internet connection for the display. The caster details are the same for every customer; only your username/password are unique. 2. Get the display online (Wi-Fi or modem): NTRIP arrives over the internet, so connect the display first. On the GFX-750 / XCN-1050 (Android-based), swipe down from the top and open Wi-Fi settings, then join a hotspot or Wi-Fi network (e.g. your phone's hotspot or an in-cab modem). If you use a built-in/connected cellular modem, confirm it shows a data connection. Wording varies by firmware - the goal is live internet. 3. Open Precision-IQ and go to GNSS settings: From the Launcher tap Precision-IQ. On the Home screen tap the GNSS tile (on some firmware via Settings > GNSS Setup). The GNSS details page shows the NAV-900 receiver and current correction source. 4. Edit the correction source: On the GNSS details page tap Edit. The Corrections option is selected by default; the Correction Source / Service is set to Autonomous - you'll change this to an internet RTK source. 5. Select the internet / NTRIP correction source: Tap Correction Service (Correction Source on some versions) to open the list and choose the internet RTK option - shown as an NTRIP / Internet / VRS entry, or under a Modem setting as 'Third Party NTRIP Modem'. Pick the option that lets you type a server address, port and mountpoint (not a radio frequency or satellite service). If unsure which entry, contact Premium Positioning support first. 6. Enter the caster server address: In the server field (Server Name/Address, Server, or IP Address depending on firmware), enter exactly: rtkpremium.xyz 7. Enter the caster port: In the port field (Server Port Number, Port, or IP Port), enter exactly: 2101 8. Enter or select the mountpoint: In the Mountpoint field enter exactly: COMMON (capitals). If the display offers a button to retrieve the source table once server and port are entered, tap it and choose COMMON. The protocol is standard NTRIP - leave any NTRIP version setting on its default (auto). 9. Enter YOUR NTRIP username and password: Type the NTRIP username and password from your welcome email - unique to your account, case-sensitive; do not share them. If lost, contact Premium Positioning to reissue. 10. Save the settings: Apply/confirm (tick/Save), then tap Home. The receiver attempts to connect over the internet and start streaming corrections. 11. Let the receiver connect and converge: With the vehicle outdoors under clear sky, watch the GNSS status indicator on the Home screen move from Autonomous toward a corrected solution. The first connection can take a short while. 12. Confirm RTK Fixed: Check the GNSS status / accuracy indicator until it reports RTK Fixed (cm-level). That confirms the COMMON corrections from rtkpremium.xyz are being received and applied. If it stays Autonomous/converging, recheck the internet connection, then server / port / mountpoint and your credentials. ### If the fix will not hold Screen/button/field names vary by display model and Precision-IQ firmware ('Correction Service' vs 'GNSS Setup', an 'NTRIP/Internet' entry vs 'Third Party NTRIP Modem') - described generically where they differ. The display needs live internet (Wi-Fi/hotspot or a connected cellular modem). If anything on your screen doesn't match, contact Premium Positioning before changing other settings.

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Have your details ready: You'll need the Premium Positioning NTRIP login from your welcome email (your own username and password) and the fixed caster settings used by every customer: Host rtkpremium.xyz, Port 2101, Mountpoint COMMON, Protocol NTRIP. Never share these or enter someone else's. 2. Confirm your hardware is wired and detected: Make sure your RTK GNSS receiver (e.g. Here3, H-RTK, or another u-blox/Unicore unit) is connected to the autopilot (Pixhawk/Cube) and the autopilot is powered. Corrections do not go straight into the GPS over the internet - they travel from your ground station, over the telemetry link, into the autopilot, which forwards them to the GPS. 3. Connect the ground station to the vehicle: Power on the drone/rover and connect your GCS (Mission Planner or QGroundControl) over USB or telemetry radio. Wait for live telemetry and at least a normal 3D fix before adding corrections. Your laptop/tablet also needs internet, since corrections are pulled from the caster. 4. Mission Planner - open the NTRIP injector: In Mission Planner go to SETUP (Initial Setup on some versions) > Optional Hardware > RTK/GPS Inject - the screen that pulls corrections from the caster and injects them into the autopilot over the MAVLink/telemetry link. 5. Mission Planner - choose NTRIP: On RTK/GPS Inject, select NTRIP from the connection-type dropdown (Serial/SerialPort options are for a local base and not used here). 6. Mission Planner - enter the caster and your login: Many versions accept the combined form user:pass\@host:port/mountpoint - e.g. YOURUSERNAME::2101/COMMON - using your own NTRIP username/password from the welcome email. If your version shows separate boxes, enter Host/Caster rtkpremium.xyz, Port 2101, Mountpoint COMMON, and your username/password. Then press Connect. 7. Mission Planner - confirm corrections are flowing: The RTK/GPS Inject window shows GPS signal status, the RTCM messages being sent, and a byte/message counter that should keep climbing. A 'Bad ntrip Response' or similar error means a wrong host/port/mountpoint or credentials - re-check them. 8. QGroundControl - open the NTRIP/RTK settings: Alternative to Mission Planner: in QGroundControl open Application Settings (gear icon) > General and find the NTRIP / RTK section (built-in NTRIP client). Section placement varies slightly by version. 9. QGroundControl - enter the server, port and credentials: Enter Host/server rtkpremium.xyz, Port 2101, and your own Username/Password from the welcome email. Leave the TLS/encryption toggle off unless support tells you otherwise. 10. QGroundControl - set the mountpoint: Set the Mount Point to COMMON. If a Browse button is shown, use it to fetch the mountpoint list and pick COMMON. Leave any RTCM message filter at its default. 11. QGroundControl - connect and verify the stream: Save/connect the NTRIP client. QGroundControl shows the connection state with message/byte counters and a data rate - these should increase once corrections flow. 12. Watch the GPS status climb to RTK: With corrections flowing, watch the GPS status on the GCS HUD/map: a normal 3D fix, then RTK Float as corrections take effect. 13. Confirm RTK Fixed: Within \~30 s to a few minutes (open sky helps), the status advances to RTK Fixed - in ArduPilot this is GPS fix type 6, the highest-accuracy cm-level solution. The HUD/GPS indicator reading 'RTK Fixed' (or '3D RTK') confirms setup is complete. ### If the fix will not hold Keep the ground station connected to both the vehicle and the internet while flying - corrections are relayed live from the caster through the GCS and over the telemetry link to the autopilot. Menu/field labels differ slightly between Mission Planner / QGroundControl versions. Mission Planner's built-in NTRIP client does not support TLS, so connect over the plain NTRIP port (2101). RTK Float = receiving but not locked; RTK Fixed (fix type 6) is the goal.

These steps connect an Autel EVO II Pro RTK / Dragonfish to the Premium Positioning correction network over NTRIP, using Autel Explorer / Autel SkyLink. They assume you already have your NTRIP credentials. ### Before you start * Your NTRIP username and password, from your Premium Positioning welcome email or your account in the XYZ Platform. * No account yet?

Only your username and password are unique to you. * Server or host: rtkpremium.xyz * Port: 2101 * Mountpoint: COMMON * Protocol: NTRIP ### Steps 1. Power up and pair, and confirm the RTK module: Power on the aircraft and controller and wait for them to pair. Make sure the RTK module is fitted and recognised. RTK corrections are received by the aircraft but configured from the controller's app, so both must be linked first. 2. Give the controller a working internet connection: Network RTK over NTRIP needs the controller (running Autel Explorer / SkyLink) online to reach our caster. Connect it to a phone hotspot, site Wi-Fi or 4G before continuing. Without internet the NTRIP login fails even when every field is correct. 3. Open the RTK settings: Open the app and enter the camera/flight view. Tap the Settings (gear) icon, usually top-right, and find the RTK section ('RTK' or 'RTK Settings'). Wording/placement vary by app version and model - look for an 'RTK' tab or sub-menu. 4. Turn on the aircraft RTK feature: Enable RTK first - usually an 'RTK' or 'RTK Aircraft' toggle at the top of the RTK screen. This switches the aircraft into RTK positioning and reveals the correction-source options. 5. Choose the custom NTRIP / Network RTK source: The RTK source list typically offers Autel's own network/RTK service, a physical base station (D-RTK / mobile station), and a custom network option. Select the custom one - 'Custom Network RTK', 'Network RTK', 'NTRIP' or 'Custom NTRIP'. Do NOT pick Autel's own service or 'Base station'. Pick whichever lets you type in your own server address. 6. Enter the caster host (server): In the server/host field enter: rtkpremium.xyz - exactly, no http\:// and no trailing slash/spaces. 7. Enter the port: In the port field enter: 2101 8. Enter the mountpoint: In the mountpoint field enter: COMMON (capitals). Some versions show mountpoints as a drop-down populated after connecting - if it's a list, connect first then choose COMMON; if a text field, type COMMON. 9. Enter YOUR NTRIP username and password: In account/username and password, enter the personal NTRIP credentials from your welcome email - unique to your account; do not use anyone else's. If lost, contact Premium Positioning support first. 10. Connect / log in: Tap Connect, Apply or Login. A success/'Login successful' state should appear. If login fails, re-check the controller's internet, host/port/mountpoint, and that your username/password were typed correctly (watch for autocorrect or trailing spaces). 11. Confirm the format is RTCM3: Our caster sends RTCM3, which Autel aircraft need. If the app lets you choose a format, leave it on RTCM3. Autel drones won't reach FIX on CMR/CMRx mountpoints - stay on the RTCM3 COMMON mountpoint. 12. Wait for the RTK status to reach FIX: Watch the RTK status in the top status bar: SINGLE → FLOAT → FIX, typically within \~10 - 60 s of a successful login under open sky. FIX means full cm-level RTK and you're ready to fly. If it sticks on FLOAT, give it more time with clear sky; if it never leaves SINGLE, corrections aren't being delivered - recheck the steps above. ### If the fix will not hold Menu names, gear-icon location and the RTK source labels differ between Autel Explorer and SkyLink and between app/firmware versions - treat the wording as a guide and pick the equivalent option. The controller must have its own internet connection for NTRIP.
