I have a question with regards to compass calibration.
I am using an ArduPilot in QgroundControl and am attempting to calibrate its Compasses.
After going to the sensor page and clicking on the calibrate sensor button I am immeditaly told to rotate the vehicle randomly.
After completing the calibration/orientation I am greeted with text of Mag(1) good orientation 0 30.5; and later
Mag(0) good orientation 0 2.1.
My question is what do these numbers indicate?
