This origin may move up and down in flight due to sensor drift. Set to 1 to control height relative to estimated distance to ground. The vehicle will move up and down with terrain height variation. Requires a distance to ground sensor. The height controller will revert to using height above origin if the distance to ground estimate becomes invalid as indicated by the local_position.distance_bottom_valid message being false. Set to 2 to control height relative to ground (requires a distance sensor) when stationary and relative to earth frame origin when moving horizontally. The speed threshold is controlled by the MPC_HOLD_MAX_XY parameter. 0
