That's correct. The MP2 doesn't rotate - it simply reinitializes the IMU yaw value to agree with the new, correct magnetic heading. https://mavicpilots.com/threads/compass-error-demonstration.66323/page-3#post-756214 I never saw this in more...

There is no need to do that. You can take actual flight data and easily compute the inertial navigation solution to compare with the actual position and velocity of the aircraft. That directly shows the accuracy that you could expect from the...

It knows its heading and airspeed from the compass and tilt angle, but it can do better than that in terms of navigating without GNSS positioning. The accelerometers and rate gyros alone theoretically provide a full 3-D position and velocity...
