Gyrocompass detects the ship’s heading. It detects the direction of true north by using a fast-spinning rotor, which is influenced by gravity and rotation of the Earth and detects ship’s heading.

The heading indicated by the gyrocompass is transmitted to receiving devices, including the repeater compass.

The ship’s heading is transmitted to repeater compasses and other ship’s equipment after the signal format is converted to serial data or to stepper or analog signals depending on what type of format the equipment requires.
