# 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).
