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

Deviation refers to the error in a ship's compass readings caused by magnetic fields from onboard electrical equipment and metal structures, leading to a difference between the gyro course (the heading indicated by a gyroscopic compass) and the magnetic course (the heading indicated by a magnetic compass). This deviation can cause navigational inaccuracies, making it essential for navigators to account for it when plotting courses. The difference between the gyro and magnetic courses is crucial for precise navigation, especially in areas where magnetic anomalies may exist. Regular calibration and adjustment of the compass systems can help minimize these discrepancies.

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.
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.
To apply latitude and speed correction in a gyro compass, first, determine the gyro's latitude and speed of the vessel. The gyro compass typically drifts due to the Earth's rotation and the vessel's speed, so adjustments are made based on the vessel's position. For latitude corrections, apply a correction factor based on the difference between true and magnetic north, while speed corrections account for the influence of speed over ground on the gyro's performance. Regularly monitoring and adjusting these parameters ensures accurate heading information.
Elmer Ambrose Sperry was the inventor of the gyro compass and gyroscope.
Because a ship is made of metal, which can affect the accuracy of a standard magnetic compass. Also, a gyrocompass is is better able to point to the true north, which is more accurate to navigation than magnetic North, which is not actually true North. Link below:
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.
when airplanes suddenly change course the corrective mechanism is a gyroscope, which has the property of resisting efforts to change its axis of spin. This system is called a gyro-magnetic compass.
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
