4.1.   Compass (45-2003) 
The Compass uses a magnetometer and an accelerometer to calculate heading data 
based on Earth’s magnetic field. The compass can return the heading data, 
accelerometer data and magnetometer data to the user. Anything that generates a 
magnetic field must be moved away from the sensor like power cables, motor or 
magnetic material. This must happen because during calibration the sensor will add an 
offset to account for other magnetic sources in the area.
