Satellite spin reorientation using a single degree of freedom momentum storage device

摘要: Methods and systems for stabilizing satellite spin about an intermediate inertia axis (Z) are disclosed. A set of gyros ( 22 ) sense the X component Y angular velocity body. single degree freedom momentum wheel 26 has a fixed transverse orientation with respect to in order store momentum. In one embodiment, is oriented parallel axis. tachometer 30 senses rotation rate ). processor 24 forms control signal representative torque be applied The based upon satellite, These methods may also used invert direction spinning satellites, ensure tumble recover preferred orientation, stabilize body against nutation, dynamic imbalance external torques.
