The heading information is to be used directly by the radars, radar plotting aids and automatic identification system. The gyrocompass is to be provided with a gyrocompass heading repeater located at the emergency steering position in the steering gear compartment and a gyrocompass bearing repeater allowing bearings to be taken over 360°.

To satisfy the requirements of PT 7, Ch 9, Section 3.1.7, M/S MERSol is equipped with two gyrocompasses. The information from the gyro’s is distributed to various locations and systems. There are four gyro repeaters on the bridge, two of which are heading repeaters primarily used for steering, the other two are heading repeaters on brackets located on the bridge wings, primarily used for taking bearings. There are two heading repeaters located in the steering gear room, which are to be used for emergency steering operations.
