Alignment and lever arms
Here you can configure the alignment of the device and its lever arm in regard to the center of
rotation of the aircraft.
On the alignment settings you only need to set up the first two axis, then the third one will be
automatically computed.
Initial Position and Date
This parameter will matter if you are using magnetometers: the initial position and date will be
used to compute the magnetic declination.
In case you use magnetometers as a heading source, then a magnetic calibration is mandatory.
A 3D calibration should be preferred over a 2D one if possible. If a 2D magnetic calibration is
performed, it will be only valid locally, and should be re-done if the aircraft is in a different
geographic area.
