Spacecraft nutation caused by applying propulsive forces to a spacecraft along an axis which does not pass through the spacecraft\s center of gravity is eliminated by a signal responsive control system which operates the propulsive forces for a predetermined time period which corresponds to an integral number of nutation periods.
A control system for a spacecraft of the dual-spin type having a spin axis and a characteristic nutation frequency, and further having a platform despun from a spinning member, for eliminating nutation caused by a thrust force not passing through the center of gravity of said spacecraft comprising: receiver means included in said spacecraft for receiving signals Transmitted to said spacecraft, and generating in response thereto a receiver means output signal; and force generating means mounted on said platform and coupled to said receiver means and, in r...
