ABSTRACT:
A gyrocompass having a gyro rotor, and a device for applying to the gyro rotor about its vertical axis a torque in proportion to an inclination angle of the spin axis of the gyro rotor from a horizontal plane so as to attenuate the north-seeking action of the gyro rotor, in which the torque is controlled to be proportional to the inclination angle for its component which varies with a period same or close to that of the north-seeking action while to be approximately zero for a component of the inclination angle which does not vary.
