The determined position is used to determine a magnetic inclination (e.g., by a global magnetic field model such as the World Magnetic Model).

If the magnetic inclination is greater than the threshold, magnetic field data is measured by the magnetometer as it is rotated through vertical rotation paths. The measured magnetic field data may be used to determine calibration values for the magnetometer compass.
