An active nutation control system for a space vehicle spinning about a geometric axis has thrusters for creating an external torque about an axis transverse to the first. The amplitude of the nutation and its phase in relation with the spinning movement are detected. A control arrangement receives signals from the nutation detectors, computes the changes in the angular direction of the angular momentum of the vehicle caused by thruster activation and energizes the thrusters when contemporaneously the amplitude of the nutation movement is greater than a p...


An active nutation control system for a space vehicle spinning about one of its geometrical axes, having: means for creating pulses of external rocking torque about an axis transverse to said geometrical axis; means carried by said space vehicle for delivering a periodically varying signal having an amplitude representative of the magnitude of the nutation of said space vehicle and a frequency equal to the nutation frequency of said space vehicle; and control means for controlling the torque-creating means, comprising: first enabling means to deliver a s...
