ABSTRACT:
A power management system for a worldwide multiple satellite system having satellites positioned latitudinally in a polar orbiting constellation, each satellite having a plurality of antenna beams, each beam having a given area of coverage or "cell," the total sum of the cells for each satellite forming a larger coverage for the entire satellite, the satellites each comprising solar cells and batteries wherein the energy within the batteries is generated by the solar cells and must be efficiently managed. The system comprises an earth based control station which programs each of the satellites within the constellation to supply power to the antenna beams of each satellite at predetermined times to avoid overlapping coverage. Each satellite comprises a voltage regulated linear power amplifier to supply only the power needed for the demand within each of the antenna's cells.
