Method of configuring satellite constellation design using multiple discrete switchable spot beams

A method and computer program to configure feeds on a satellite (300, 310, 320) to provide for redundant coverage when a satellite (300, 310, 320) fails. Further, this method and computer program can enable the switching of feeds from commands from a ground station (30) to activate certain feeds and deactivate other feeds when demand for service changes. In addition, this method and computer program allow for repositioning of satellites so that when one satellite fails another satellite may take over its area of coverage by switching active feeds without the need for placing another satellite in orbit.
