Autopilot wrong GPS logs

My quad crashed into a house while in auto, but the logs display that it should have been in the field (they are incorrect).

Green arrow: were should have landed

Blue arrow: were he thought he was going

Red arrow: were he went

The compass was faulty (no further accident from that day), but should I check other components as well? I'm using a 3dr GPS.

  • Hi, check your compass (not GPS) under different motor load conditions. And repeat the tests with the nose pointing in different directions. Are the indicated compass bearings real?

    Move high current DC wiring further away from the APM board.
