ABSTRACT:
An electrostatic pickoff well suited for use in a two-axis electrostatically-captured rotor rate gyroscope is shown. Displacement currents, which flow between stator electrodes and the V-shaped annular electrically conductive rotor capturing the rotor, are processed so as to produce signals related to rotor position but independent of capture currents. When closed through a 5 degree-of-freedom positional servomechanism, rotor position signals are effective in producing rotor capture with net zero rotor current without producing rotor distorting forces.
