Abstract
A gyro compass according to the present invention includes an inclinometer for detecting inclination of the spin axis of a rotor with respect to the earth's surface, a horizontal axis torque applying device for exerting a torque about the horizontal axis of the rotor, a vertical axis torque applying device for exerting a torque about the vertical axis of the rotor, and an equilibrium tilt angle storing device for storing an inclination angle of the rotor while the gyro compass is in the equilibrium state. An inclination adjustment controlling device for adjusting an inclination angle stored of the rotor to the inclination angle in the equilibrium state by controlling the vertical axis torque applying device.
