Septentrio AsteRx UAS GPS Family¶
The Septentrio AsteRx-m2 UAS RTK GPS and other AsteRX-m RTK GPS are relatively expensive but also highly accurate RTK GPS.

Note
Mission Planner GCS is the only GCS to support this feature currently.

To setup this using GPS2 input (serial4) configure these parameters:

If you want to inject RTCM corrections to both GPS1 and GPS2 then use: - GPS_INJECT_TO,127
