Abstract
A satellite communications system operative with at least one existing terrestrial communication system for carrying traffic is described. The communication system has a plurality of satellites in earth orbits, each satellite including a battery for sourcing electrical energy. The battery has energy sourcing limits. Gateways, bidirectionally linked to the plurality of satellites are also provided. A computing center, linked to the gateways, has a traffic control means for allocating traffic to the gateways. The traffic control means has three parts a power demand model for computing a first traffic allocation of traffic for each satellite; a satellite battery performance model descriptive of the energy sourcing limits of the on-board batteries; and a control law for applying weights to the first traffic allocation by using the battery performance model to obtain a second traffic allocation for each satellite. The second traffic allocation induces an electrical energy consumption in each of the satellites that is less than the battery energy sourcing limits.
