ABSTRACT:
A GPS receiver fault detection method for use in a GPS attitude determination system having Q Receivers, wherein Q>3, includes providing R attitude solutions using subsets of P Receivers and signals from two or more space vehicles, wherein 3.ltoreq.P.ltoreq.Q-1. Post-update measurement residual sets equal to the number R of attitude solutions are determined. Each of the post-update measurement residual sets corresponds to one of the attitude solutions. "S" Receiver faults are detected by comparing the R post-update measurement residual sets, wherein 1.ltoreq.S.ltoreq.Q-3. A faulty Receiver detection system for carrying out the method is also described.
