Enabling the EF Mag Hard Iron Auto Calibration allows estimation of the magnetometer bias (bias
tracking) for purposes of auto- calibration. Enabling the EF Mag Soft Auto Calibration allows
estimation of the magnetometer scale factor (scale factor tracking) for purposes of auto-calibration.
To enable, select the sensor name in the MIP Monitor software main window, then select Settings >
Device > Estimation Filter > EF Tracking and check the white box to the left of Enable EF Mag Hard
Iron Auto Calibration and Enable EF Mag Soft Iron Auto Calibration. Auto Calibration only takes
place if the magnetometer is used as a heading aiding source.
