摘要： 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.

摘要： A spacecraft is provided that includes a communications payload having an antenna support structure and an antenna boom coupled to the antenna support structure. An attitude sensor may be mounted to the antenna boom. The attitude sensor (such as an Earth sensor, a star tracker and/or a sun sensor) may be mounted at a root of the antenna boom.
