Hello paparazzi community
After 8h of trying to get rid of my drift on phi you are my last hope.
Every hint is useful!
I think it has something to do with the AHRS.
Compensation of psi drift with MAG
The plot shows a fast 90° turn clockwise and back again.
In the lower plot you also can that the bias changes a lot, is that
"normal"?
Lisa M 1.0 + Aspirin IMU 1.5
(I did the calibration of Accel and mag a few time with similar results)
Thx for any hint!
