A gyrocompass is used to determine true north by using the Earth's rotation and the principle of gyroscopic stability. It does not rely on magnetic elements, making it less prone to interference from magnetic fields. It is commonly used in navigation for ships and aircraft to provide accurate direction information.
Hermann Anschütz-Kaempfe is credited with inventing the gyrocompass in 1904.
Elmer Ambrose Sperry, an engineer and inventor, who founded the Sperry Gyroscope Company in 1910.
The gyrocompass was invented by German inventor Hermann Anschütz-Kaempfe in 1904. It uses the principles of a gyroscope to find true north rather than relying on magnetic north like a traditional compass.
A gyrocompass is important because it provides accurate direction determination that is not affected by magnetic interference, making it ideal for navigation in areas with high magnetic deviation. It is commonly used in ships and aircraft for precise heading information, allowing for safe and efficient navigation.
It is powered by electricity, so a cut off of this energy will stop your compass. That is why vessels nowadays vessels are equipped with UPS(uninterruptable power supply) which gives you extra power for use in hours to use the compass.

Gyrocompass is a mechanical device that determines direction. It is used in navigating all major commercial and naval ships, and some aircraft and land vehicles. A gyrocompass is more accurate than a magnetic compass, which relies on the earth's magnetic field to indicate magnetic north. A gyrocompass points to true north, or geographic north. It is not affected by magnetic forces or by the rolling and pitching of the vehicle.

The most common control system used in international maritime is the Integrated Navigation System (INS). This system integrates various navigation instruments such as GPS, radar, and gyrocompass to provide accurate and reliable navigation information to the ship's crew for safe and efficient navigation.
There are three main types of magnetic compasses: the traditional liquid-filled compass that uses a magnetic needle, a digital compass that uses sensors to detect magnetic fields, and a gyrocompass that uses the Earth's rotation to determine direction. Each type has its own advantages and limitations, depending on the specific use case.
The compass used to find direction at sea is called a magnetic compass. It consists of a magnetized needle that aligns itself with the Earth's magnetic field, indicating north. Navigators often use variations of this compass, such as the gyrocompass, which is less affected by magnetic interference and is used for more precise navigation on ships.
