ABSTRACT:
A gyrocompass comprises a gyroscopic element having a stabilizing gyro with a relatively heavy rotor rigidly secured to a driving shaft and a control gyro with a rotor of lower inertia mounted on the same driving shaft as a free rotor gyro. A case enclosing the gyroscopic element and a drive motor is mounted in a vehicle with the spin axis in the north south plane in gimbals with a nominally vertical outer axis and an inner or tilt axis in the east-west plane. The stabilizing gyro is slaved to the control gyro by means of signals from pick-offs associated with the latter so as to zeroise misalignment, and the tilt gimbal is pendulous to provide a gravity reference, so that the azimuth misalignment signal between the gyros generates an opposing tilt torquer current which is a measure of the gyro tilt angle.
