I am using the M20050-1 as the GPS for our student built flight computer, following the design guidelines on the data sheet and from tech support. However during testing, we received commands such as “$GLGSV,1,1,00*65\n’” and “$GNVTG,0.00,T,,M,0.00,N,0.00,K,N*2C\n’” when interfacing the GPS with a Raspberry Pi Zero, and are not able to receive coordinates from the GPS. We suspect that the GPS is not fixing to the satellite.
I was wondering how would you recommend to approach the issue? I read on the data sheet about an external antenna, how should the external antenna be used and would it help fix to the satellite?
