Gyrocompass

A Gyro compass is a form of gyroscope, used widely on ships employing an electrically powered, fast-spinning gyroscope wheel and frictional forces among other factors utilizing the basic physical laws, influences of gravity and the earth’s rotation to find the true north. It is used for finding the right direction. Unlike magnetic compass, gyro compass is not hampered by external magnetic field.  It is used to find correct North Position, which is also the earth’s rotational axis.
