SuperSurv (Android)

These steps connect a SuperSurv (Android) to the Premium Positioning correction network over NTRIP, using SuperSurv 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 on the customer portal.

• SuperSurv 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. Pair your receiver in Android first: Power on your external Bluetooth GNSS receiver. 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.
