What use of gyro compass on board?

A gyro compass is used on board ships and aircraft to provide accurate heading information that is not affected by magnetic variations or disturbances. It operates based on the principles of gyroscopic inertia, allowing it to maintain true north alignment regardless of the vessel's movement. This reliability is crucial for navigation, especially during long voyages or in regions with magnetic anomalies. Additionally, gyro compasses are essential for automated navigation systems, enhancing safety and efficiency.
