Agile (electronically steerable) beam sensing with associated on-board processing, previously used exclusively for positioning of antennas for beam formation and tracking in communications systems, is now also used for satellite active attitude determination and control. A spinning satellite (100) is nadir oriented and precessed at orbit rate using magnetic torquing determined through use of an on-board stored magnetic field model (520) and attitude and orbit estimates (212). A Kalman filter (211) predicts parameters (202, 203) associated with a received...


An on-board attitude determination system for a spacecraft orbiting a celestial body comprising: means for estimating the orbit and attitude of the spacecraft relative to a plurality of remote sources of coherent energy signals; an agile beam sensor sensing the locations of the remote sources; means for pointing the agile beam sensor at the estimated relative locations of the remote sources; means for determining error signals representative of the difference between the estimated locations of the remote sources and actual locations of the remote sources...
