Septentrio AsteRx-m UAS and AsteRx-m2 UAS RTK GPS

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



This GPS is supported in Copter-3.4 (and higher), Plane 3.7.0 (and higher) and Rover 3.0.1 (and higher). Mission Planner GCS is the only GCS to support this feature currently.
