Abstract
A two degree of freedom gyroscope having a drive motor (20), with a permanent magnet rotor (22), which comprises a sensing coil (32) looped around the permanent magnet rotor (22) and disposed in a plane orthogonal to a null spin axis, a torquer coil looped around the permanent magnet rotor (22) and disposed in a plane orthogonal to the null spin axis, and torque drive elements (62, 64, 65) responsive to the signal induced in the sensing coil (32) when the actual rotor (22) spin axis is displaced from the null spin axis (28) for providing current to said torquer coil (34) to urge the axes to coincide. Demodulators (70, 72) can be provided for providing output information in an X-Y coordinate format which is indicative of the actual input angular rates about corresponding axes.
