Abstract
A two-step method is used to reconfigure beams among different orbital slots for a satellite system. The satellite is biased at one or more orbital slots for a back-up mission, while it looks at the sub-satellite point for the primary mission. Body steering is achieved using pitch and roll biases. The main reflector of the antenna is gimballed in order to steer the beams to different locations for the back-up mission. Beam size is controlled through the use of different sized reflectors and by varying the feed size. Different sized beams are interleaved among multiple reflectors.
