The telemetry parameter GPS Sats goes to zero for about 1 second immediately after landing. The typical value of GPS Sats is 16. When the heli has landed and the Vibes parameter reaches 1%, the GPS Sats value is 0 for 1 second and then 16 again. I had no problems during the flight.
This effect occurs with my two helicopters with GeoLink V2 and Spirit GT. A third heli with GeoLink V1 is ok.
I am sure that GeoLink V2 is not really losing satellites yet.
