Abstract
A suspension gyroscope has a stator and a rotor rotatably mounted with respect to the stator. The rotor has at least one generally hemispherical portion which is, at least in part, electrically conductive. The rotor may also have disc-like portions which project radially outwardly therefrom. Electrical coils serve to generate magnetic fields which induce eddy currents in the hemispherical portions and the disc-like portions. These coils serve to monitor the positions of the rotors with respect to three reference axes. A sensor for measuring departure of the rotor from a desired position is provided and may be optical or magnetic in nature.
