74 than 0.5° nominal heading accuracy, 0.1° resolution along with a +/- 80° pitch and roll range, and come with a model of the global magnetic field in updatable software. User-driven calibration routines are also available to cancel out stray magnetic fields and compensate for hard and soft iron distortions; the former are permanent distortions often caused by a piece of magnetic material attached to the same reference frame as the sensor, the latter by deflections in or alterations to the existing magnetic field. As well as backing up other navigation sources, combined magnetic and inertial systems also provide heading and orientation feedback in applications such as bomb disposal robots and UGVs with various degrees of autonomy, which often venture out of the operator’s sight. Navigation systems can also integrate active sensors such as radar, video, Lidar and sonar, but that is a subject for another focus.
