Abstract :
Tripulse is a novel orientation/attitude estimation system that is designed to accurately estimate the orientation of a satellite borne phased array relative to one or more Earth stations. This system has an accuracy potential that is significantly better than conventional Earth-Moon-Sun attitude sensors. Tripulse has conceptual similarities to amplitude comparison monopulse systems used in tracking radars. Detailed Tripulse statistical performance analyses for noise, beam-forming quantization errors, and hardware failures are presented
