Compass Calibration
This option is available only when Magu
(electronic magnetic compass) is also present on the CAN bus. Before
you do the calibration, you need to finish the AHRS calibration.
Compass and AHRS work in pair and information from AHRS greatly
increases the precision of compass. Please, also make sure that the
system is running at least for 15 minutes. This time is required to
warm up the electronic and stabilize the numerical filters.

When ready, you need to rotate the aircraft for ca. 400 degrees.
Direction of rotation and start azimuth are not important. When
rotating, try to keep a steady pace for the best results – this will
result in a constant angular velocity. When turning aircraft, the
progress bar grows and the procedure is complete when it reaches
