초록

Spacecraft thruster systems are provided that can realize station changing, station keeping and momentum dumping in spacecraft while minimizing loss of spacecraft service time. The systems are formed with pairs of E and W thrusters, NE and SE thrusters and NW and SW thrusters whose thrust directions are each defined by respective polar angles .phi. and slew angles .alpha.. The E and W thrusters are especially suited for rapid station changing while the remaining thrusters generate normal, tangential and radial thrust components required for station keepi...

1. A thruster system that facilitates station changing, station keeping and momentum dumping for a spacecraft when it is in an orbital plane with its yaw axis directed substantially at the earth, its roll axis directed substantially along the spacecraft's velocity vector and its pitch axis directed substantially normal to said orbital plane, the system comprising:a northeast (NE) thruster that is tilted southward from said pitch axis by a NE polar angle that is less than 80.degree. and rotated eastward from said yaw axis by a NE slew angle that is less t...
