HOWEVER...The IMU contains: a 3-axis accelerometer, a 3-axis angular velocity meter and a barometric altimeter.
Therefore it is not a stretch that during IMU calibration the barometer is zeroed in a similar fashion to the accel. and velocity sensors.
If so, this might contribute to the error you are experiencing.
Nope ...... unfortunately there's no calibration for the altimeter/barometric sensor.
I had one that read + to - 60 feet on the ground, and DJI California said to return itto mt dealer, as there is no calibration for it.
It either works properly and reads within a few feet, or it's gone Elvis.
Thanks.
How does it 'know' what it's altitude is then (within a few feet)?
