       <long_desc>When set, the EKF checks the strength of the magnetic field to decide whether the magnetometer data is valid. If GPS data is received, the magnetic field is compared to a World Magnetic Model (WMM), otherwise an average value is used. This check is useful to reject occasional hard iron disturbance.</long_desc>
