Setting Up RTK and Resolving Common Issues

  • Updated

Configure RTK in Locusview by pairing the GPS, enabling Google Location Services, entering correctly formatted server credentials on port 10000, selecting your state stream, and verifying “RTK Connected” or “Fixed.” Troubleshoot GPS, connection, accuracy, and disconnection issues as described.

Checklist (Before You Begin)

  • GPS On & Paired: Power on the GPS device and ensure it is paired to the tablet via Bluetooth.
  • Turn on Google Location Services 
    • Open Google Maps.
    • If you see “Make it your map,” tap Skip.
    • Tap the Locate Me button (target icon) and choose While Using This App when prompted.
    • If prompted “For a better experience, your device will need to use Location Accuracy,” tap Turn On. The map should zoom to your blue pin.
  • Good Internet Connection: Ensure stable cellular data or Wi-Fi connectivity.
  • Correct Credentials: Verify you have the correct RTK/NTRIP Address, Port, Username, and Password.

    • Force close the Locusview app.
    • Reopen Locusview → Menu > Devices and select the GPS again.
    • Set up RTK once more using the steps above.
  • “Connection failed. Verify settings and retry" error
    • Ensure Google Location Services is on 
    • Check your credentials carefully:
      • Address: all lowercase.
      • Port: 10000.
      • Username: first letter capitalized (unless rtk).
      • Password: only “A” capitalized (unless rtk).
    • Common causes: misspelled address or incorrect capitalization.
    • Force close Locusview, power the GPS off/on, and retry.
  • RTK connects but accuracy is poor (DGPS or Float):
    • Move to an open-sky area; avoid buildings or obstructions.
    • Ensure stable internet; toggle Airplane Mode on/off to refresh.
    • Re-select the GPS and confirm the correct state stream is chosen.
  • Frequent disconnects:
    • Check for weak signal or Wi-Fi drops.
    • Ensure only one device is using the same RTK credentials at a time.

Additional Notes and Best Practices

  • Always re-select the GPS before configuring RTK to refresh the Bluetooth link.
  • Open Locusview after the GPS is powered on and paired.
  • Keep GPS firmware updated and fully charged.
  • If shared credentials are in use, only one active session can connect at a time.

FAQs

  • Where do errors appear during RTK setup?
    Errors display at the top of the RTK screen in Locusview.
  • My address works on one tablet but not another.
    Re-enable Google Location Services and verify the address is all lowercase on both devices.
  • Do capitalization rules matter?
    Yes. Address must be lowercase. Username is first-letter uppercase (unless it’s rtk). Password has only the “A” uppercase (unless it’s rtk).
  • I connected but don’t see my state.
    Gen 2: tap Connect to server first, then pick your state. Gen 3: tap Select Stream, then choose your state. If you are in Kentucky, the city is fine.
