Abstract
A communications satellite method and are provided for controlling a configuration of spot beams produced by a communications satellite. A plurality of spot beams are generated by a communications satellite while maintained at a first orbital position with respect to a first portion of the earth. The plurality of spot beams are configured in a first cell pattern to substantially encompass a first portion of the Earth. The satellite is moved to a second orbital position with respect to a second portion of the earth. Once moved, the satellite is reconfigured such that a second plurality of spot beams form a second pattern 85 to substantially cover the new portion of the earth of interest. A network of switches allows the satellite 10 to be reconfigured for operation from multiple orbital positions. The switching network directs individual feeds to different signal paths having different bandwidth and power capabilities.
