Apparatus for autonomously performing stationkeeping maneuvers for three-axis stabilized spacecraft (1) such as geosynchronous satellites. For each of one or more spacecraft axes (y, z) the invention autonomously performs desaturation of a momentum/reaction wheel (31-32, 41, respectively) associated with that axis, while simultaneously accomplishing the preselected compensation of the spacecraft\s east-west position. Thrusters (35-38, 45-48) having a polarity corresponding to the desired desaturation polarity are fired in a particular sequence: when a pr...


Apparatus for controlling a 3-axis stabilized spacecraft, comprising: at least one momentum/reaction wheel mounted on board the spacecraft for maintaining the spacecraft\s attitude with respect to an axis; a set of thrusters mounted about the periphery of the spacecraft for desaturating the momentum/reaction wheel and for accomplishing change in velocity maneuvers; coupled to the momentum/reaction wheel, means for determining when the momentum/reaction wheel reaches saturation; and coupled to the determining means, means for performing any desired desatu...
