A gyro compass is powered by electricity, typically from the ship's electrical system. The gyro compass relies on the principle of a continuously spinning gyroscope to maintain its orientation and provide accurate heading information.
When a force is applied to a gyro compass, it will try to maintain its alignment in space and resist external influences due to its gyroscopic properties. The gyro will precess in response to the force, causing the compass card to tilt or rotate. Ultimately, the gyro compass will seek to stabilize itself and align with the true north once the external force is removed.
Both magnetic compasses and gyro compasses are important for navigation at sea. Magnetic compasses are reliable and do not rely on external power sources, making them essential as a backup in case of equipment failure. Gyro compasses are more accurate and stable, providing precise heading information unaffected by magnetic interference. A combination of both types of compasses ensures redundancy and enhances safety in navigation.
The term Gyro refers to any Gyroscope (Space,Earth,Tied or Rate) whereas Directional Gyro is typically a Tied Gyro which is used in Aircraft for the purpose of Heading reference in DGI (Directional Gyro indicator) because it does not suffer any errors like magnetic compass.
A magnetic compass uses the poles of our planet to stay in alignment. A Gyroscopic compass is set to a particular direction and tends to try to stay that way. After time, even the best Gyro will start to precess (move). This means the you will need to compare your Gyro to the magnetic every 15 minutes or so. Some modern gyroscopic compasses are capable of auto resetting to do this update automatically
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.

Gyro repeater is an instrument used for taking bearings by the use of a gyro compass. It displays the heading information provided by the gyro compass, allowing for accurate and reliable navigation on a vessel.

Most notably, the gyro compass.
A gyro compass consists of a spinning gyroscope, a compass card, and a correcting mechanism. The spinning gyroscope maintains its orientation in space and serves as the reference point for navigation. The compass card aligns with the gyro's axis to indicate the heading of the vessel. The correcting mechanism adjusts for errors due to the vessel's motion to provide accurate heading information.
A gyro compass is a type of non-magnetic compass that uses a gyroscope to find true north, rather than magnetic north. It operates on the principles of angular momentum and gyroscopic inertia, allowing it to maintain a stable reference to the Earth's rotation. Gyro compasses are commonly used in marine navigation, aviation, and by ships and submarines, as they are unaffected by magnetic fields and provide accurate heading information. Unlike traditional magnetic compasses, gyro compasses require electrical power and can take some time to stabilize after being powered on.
