A spacecraft includes a body defining a center of mass, and an attitude control system, for generating attitude error signals representing deviation of the body from a desired attitude. A plurality of thrusters mounted on the body have nominally parallel thrust components, in a particular direction. The thrusters are arranged in pairs, which produce opposed torques. A velocity change controller is coupled to the thrusters, for generating pulsatory firing command signals for the thrusters for a particular total time duration, for achieving a desired veloc...
[ What is claimed is:] [1.] A spacecraft, comprising:a body defining a center of mass:attitude sensing means coupled to said body, for generating attitude error signals representative of deviation of said body from a particular attitude;a plurality of thrusters mounted on said body, with mutually parallel thrust components in a particular direction, said thrusters being arranged in pairs, with the thrusters in each pair producing substantially opposed torques about said center of mass;velocity change control means coupled to said plurality of thrusters, ...
