gnss-sdr seems to be working, but never show coordinates or synchronization with any satellite.

I know that GPSDO included with my USRP only works with GPS ANT connection so, how can i specify to gnss-sdr to use GPS ANT connection?

I'm using the configuration file provided by the gnss-sdr official website for USRP devices.

My hw.

  • USRP B210.
  • Active antenna.
  • Taidacent Bias-Tee.

You don't. the GPS ANT connection goes to to the GPSDO only, not to the SDR. You will need another GPS antenna connected to RF A or RF B (or the same antenna, if you don't mind losing the use of the GPSDO temporarily).

  • $\begingroup$ Hello, Thank you for your reply. If I understand, it is necessary the use of 2 GPS antennas by connecting one of them to the GPS ANT port and the other one to the RX A or B, then execute my configuration file with gnss-sdr. Is that right? $\endgroup$ Sep 7, 2022 at 20:36
