Position Home ardurover in flight data and position home in flight planner are not match. Ardurover are move around this make it impossible to specify position home in flight data and flight planner. because position home move along ardurover .
Normally home is set when the vehicle arms. Instead of using a waypoint, maybe use the return-to-launch command?
The core problem though is that the GPS is moving around a lot. To some extent that’s just how GPS is so you can’t expect to resolve this completely. If the vehicle’s GPS is upgraded to a better GPS (like a Ublox F9P) then it will get better though.
Ah, ok. While the vehicle is disarmed, the home position is updated to the vehicle’s location every few seconds.
Home will stop moving once you arm the vehicle or if you manually move home from MP’s Data screen, right-mouse-button-click on the map and select “Set Home Here”, “Set Home Here”.
