초록

There is provided a method and system for simultaneous north-south stationkeeping and 3-axis momentum management for a geosynchronous orbiting spacecraft. The spacecraft has a first thruster, a second thruster, and at least three momentum wheels mounted on-board the spacecraft. The first and second thrusters are mounted adjacent to a north and a south face of the spacecraft, respectively, on an anti-earth side of the spacecraft and are aligned to produce thrust vectors slightly off from the spacecraft's center of mass. The first and second thrusters are ...

[ What is claimed is:] [1.]1. A method for providing simultaneous north-south stationkeeping and momentum management in a three axis momentum wheel stabilized spacecraft, comprising steps of:firing a selected one of a plurality of thrusters at opposing points in an orbital path of the spacecraft so as to effectively cancel radial effects in a change of velocity; andwhile firing the selected one of the plurality of thrusters, gimballing the thruster to null disturbance torques and desaturate wheel momentum accumulation.
