Carlson BRx7 / BRx6+

These steps connect a Carlson BRx7 / BRx6+ 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 on the customer portal.

• Carlson SurvPC / SurvCE.

• 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. 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.
