Calibrating the Gyros
The TracVision antenna’s gyros continuously measure the motion of
your vessel and send this data to the antenna’s motor control circuitry
to keep the antenna pointed at the satellite. At the factory, each
antenna gyro is precisely calibrated to work with the antenna’s circuit
board. Therefore, if you ever replace a gyro or circuit board in your
antenna, follow the steps in Figure 22 to recalibrate the gyros for the
new part.
Figure 22 Gyro Calibration
Calibrate the gyros only if directed by KVH Technical Support, and
only while the vessel is stationary in calm water. A poor gyro
calibration can reduce the performance of the antenna.
