Selecting Heading Reference Source
The Heading Reference Source menu provides the option to
override the GyroTrac’s external sensor module in favor of
another source, such as a ship’s gyro, as follows:
•
INTERNAL – GyroTrac will receive and use
heading data from its sensor module. The Control
Compass menus will be available.
•
EXTERNAL – GyroTrac will receive and use
heading data from an external heading source. As
a result, the Control Compass menus will be
inactive and hidden. Refer to Figure 2-21 on
page 32 for details on connecting a ship’s gyro to
the ADCU.
