1. A closed loop oscillating gyroscope for detecting motion about an input axis, comprising:

  • a fixed case;

    a servo driven member mounted to said fixed case, for oscillation about a servo axis;

    a torque summing member mounted to said servo driven member to allow rotational motion about an output axis corresponding to the gyroscope input axis, and transverse to said servo axis, wherein said rotational motion is induced as a result of gyroscope rotation about the gyroscope input axis;

    a rotor driven member mounted to said torque summing member for oscillation about a reference axis transverse to both said output axis and said servo axis;

    first oscillation means for oscillating said rotor driven member about said reference axis;

    second oscillation means for oscillating said servo driven member about said servo axis;

    means for sensing at least one aspect of the motion of at least one of said servo driven member and said torque summing member; and

    means, responsive to said means for sensing, for determining the rotation of said fixed case about the input axis.
