|Gyrocompass is a compass that is independent of the magnetic field of the earth and depends upon the properties of the gyroscope and upon the rotation of the earth. |

Most larger ships carry a gyrocompass which relies on the gyroscopic effect in which a freely spinning body aligns itself at right angles to the direction of movement. The gyroscope senses the spinning movement of the earth and aligns its axis of spin north/south. The advantages of the gyroscope is that it does not require corrections of the magnetic compass but it does require a reliable source of electricity and also takes some time to start up.
