<p>A nutation sensor and nutation control system using a relative spin phase sensor (28) in a dual-spin stabilized satellite (20) is disclosed. The relative spin phase sensor (28) provides index pulses indicative of the relative spin phase and rate between the satellite rotor (24) and platform (22). Nutation of the satellite perturbs the relative spin position of the rotor (24) and platform (22) and means (44, 46) are provided for analyzing index pulse arrive times to calculate nutation of the satellite. In the nutation control system, means (32) are provided to apply a nutation damping torque to the satellite.</p> |
