Gyrocompasses
At least one gyrocompass should be enabled at all times to provide heading information
to the system for automatic control of heading.
Rejection of heading measurements
Normally, all available gyrocompasses will be running and enabled for use.
If the difference between the measured value read from a gyrocompass and the model
value exceeds a predefined limit, an alarm message is displayed; for example:
Gyro 1 prediction error
In the optional
Autopilot
mode, when two gyrocompasses are running and enabled, the
system will normally use the preferred gyrocompass.
The system receives and compares the signals from both gyrocompasses, but uses only
one of them to calculate the vessel's heading. You can specify which gyrocompass is
preferred for use by the system.
If a “Gyro prediction error” is for the gyrocompass that is in use, the system will change
automatically to the other gyrocompass.
Note
In the event of a “Gyro prediction error”, you should always check the values from the
gyrocompass on the Sensors view and compare with an alternative source of heading
information to confirm if the gyrocompass is faulty.
Displayed heading information
You can examine the measured values from the in use gyrocompass in the Heading area
of the display (see
on page 23), You can also examine the status and
measured values for all gyrocompasses on the Sensor view (see
on page 38).
