<p>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 R 3 ≤ P ≤ 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 ≤ S ≤ Q-3. A faulty Receiver detection system for carrying out the method is also described.</p> |
