Control Compass Mode
The Control Compass function allows you to turn autocalibration
on/off, read the calibration score, and clear the calibration.
Selecting Autocalibration
Every antenna’s internal sensor module is calibrated at the
factory in a perfect-world environment. However, hard and soft
iron effects on your vessel can distort the local magnetic field,
causing errors in the reported heading. These errors are
minimized by mounting the antenna in a suitable location and
are further removed by the system’s autocalibration feature,
which compensates for minor magnetic distortions while your
vessel is moving. The more the vehicle moves with
autocalibration turned on, the more accurate the sensor will
become.

Setting Autocalibration
A well-calibrated sensor is crucial
to system performance. If you shift,
remove, or add equipment near the
antenna, KVH suggests keeping
autocalibration ON so that the
sensor will automatically recalibrate
itself.
The factory default setting for
Autocalibration is ON.
