ABSTRACT:
A geostationary orbital box is divided by radially-oriented planes to form orbital sub-boxes. A thruster system facilitates station keeping satellites in each of these orbital sub-boxes. The thruster system includes thruster pairs that are positioned on an anti-nadir face of each satellite and directed through the satellite's center of mass. In addition, multiple satellites can be stationed in each of the sub-boxes by causing them to rotate in a chosen one of a clockwise and a counterclockwise direction and to be spaced from each other in at least one of a radial direction and a normal direction. To enhance the fine-grain control of each of the satellites, the thruster system preferably uses ion-propulsion thrusters.
