This section provides an overview of the GC80 and GC85 Compact MK2
Gyro compasses and their components.
GC80 and GC85 Compact MK2 Gyro compasses have been designed for
any size of vessels to enhance the navigational capabilities and reliability.
The Gyro compasses eliminate the inconvenience and limitations of
magnetic compasses, and provide a variety of electrical outputs to supply
accurate and consistent heading information to other navigational
equipment.
GC80 and GC85 Compact Gyro systems have different Sensitive elements,
but use the same GC80 Compact MK2 Control unit. The systems are
identified by divergent DIP switch settings in Master compass and in the
Control unit.
A GC80 or GC85 system is identified by the labelling on top of the Master
compass' case as shown in the figure below.
The labelling on the Control unit is identical for both Gyro systems.
The GC80/85 Compact MK2 Gyro compasses display and outputs bearing
information. Although the system continually checks for faults while the
system is running, failures or malfunctions may occur.
Any errors in input information will generate an alarm. These errors may
also cause large jumps in the output bearing from the Gyro compass. If this
happens, any external equipment depending on the bearing output from
GC80/85 should be operated manually or switched to other bearing
sensors.
To assure long time safe operation, the following precautions should be
taken:
- Assure that the operator is familiar with the use of the Gyro
compass.
