Qfield connection with gps station

I am currently using QField to draw routes, poles, and other features.
Recently, I installed a GPS Station to improve accuracy and achieve better results. However, I am facing an issue:

  1. First, I connect the tablet to the GPS Station through its host using the Station’s own application.

  2. Once connected, the accuracy improves to around 1 cm.

  3. Then I open QField and start drawing.

  4. After a few minutes, the connection between the tablet and the GPS Station drops automatically. The only way to restore it is by reopening the Station’s application.

I also tried to connect directly from QField to the Station using the Connection Type settings, but I could not find my Station’s server type there. My device only provides NTRIP, but QField did not detect it.

My question:
Is there any way to add my Station’s NTRIP server manually in QField, or do you have any suggestions to prevent the connection from dropping?

Thank you in advance!

Hello,
In order to suggest a solution, a few more details are needed.

  • What operating system is on the tablet? Android, iOS, Windows?
  • Which exact GNSS device are you using? Manufacturer, model name?
  • How is the GNSS and tablet connected? Bluetooth, USB cable?
  • How is the GNSS app connected to QField?

Best regards,
Thomas

I hope I understood this correctly. You are using the SV100 as a portal base station and the T8 GNSS tablet with a separate GNSS antenna as a rover. The tablet is probably running SingularPad Field Surveying App.
QField itself cannot receive and process data from an NTRIP server. With QField, you can either use the device’s internal antenna or read an NMEA data stream provided either directly from a Bluetooth device or via a UDP or TCP port.
Please check if the SingularPad Field Surveying app offers the option to use it as a simulated GNSS device in Android (see Android developer settings) or if the app can output the NMEA data via a UDP or TCP port.
