Hello I have tried to calibrate my compass at least 50 times and just one work. The horizontal rotation is ok the green light appear. The problem comes with the vertical one it keeps appearing the yellow and red light. Help plz

In your vertical calibration, which way is your camera pointing?

You need to point the camera down and rotate;  , compass calibration is at 3:00.

I had a similar problem yesterday. after 20 minutes I saw that the S1 switch was in Atti mode not in GPS.
I was useing the App to start the calibration.

Try measures above and if these do not work for you, you can try ↓

1. Find another place....
2. The Compass may has been magnetized, you need to find a magnet for degaussing.

First time I've seen this video.  Apart from being a very attractive young lady - it was done very professionally and informative.  Like it.
