Mag Adaptive
Enabling this feature will allow the filter to reject magnetometer readings when the magnitude error
exceeds the high limit (in m/s ^ 2). The bandwidth (in Hz) sets the cutoff frequency of the low pass
filter applied to the magnetometer error (
see Communications Bandwidth on page 45
). To find this
setting, select the sensor name and then Settings > Device > Estimation Filter > Mag Adaptive.
Manual Adaptive (default setting): Enter user-set fixed values.
Auto- Adaptive: Automatically estimates the values internally. It is important to have accurate
location information (lat long) in order to have an accurate value for the local magnetic field
magnitude.

NOTE
For best results, perform a hard and soft iron calibration or enable Auto-Mag calibration prior
to initiating the Mag Adaptive function.
