ABSTRACT:
A method and system is described for simultaneously precessing and nutation damping a spinning spacecraft that includes a computer, thrusters for precession and nutation damping and gyros aligned with or parallel to each of three orthogonal axes with the x-axis being the spin axis. The gyro information from three orthogonal axes is used to compute the momentum vector and target vector. The error vector is computed from the computed momentum vector and target vector. When the error vector's component along a given axis orthogonal to the x-axis changes sign, the thrusters are fired to apply corrective torques according to a computed control error.
