A gyrocompass is a navigational instrument that uses the principles of gyroscopic motion to determine true north. Unlike magnetic compasses, which can be affected by nearby magnetic fields, a gyrocompass remains stable and accurate, making it ideal for maritime and aviation applications. It operates by spinning a gyroscope, which aligns itself with the Earth's rotation, providing a reliable reference point for navigation. Gyrocompasses are commonly used on ships and aircraft, where precise navigation is crucial. They can also be integrated with other systems, such as GPS and inertial navigation systems, to enhance overall navigational accuracy and reliability.
