<p>A fault exclusion (FE) system for a global positioning system (GPS) receiver which upon detection of a faulty satellite, for example, by a fault detection (FD) system, such as a receiver autonomous integrity monitoring (RAIM) system. The FE system computes the test statistics for all satellites and ranks the satellites in descending order of their test statistics. The FE system excludes data from the satellites one at a time starting with the satellites at the top of the list. Should a subsequent satellite anomaly be detected, the FE system excludes satellites based on the test statistics computed for the previous satellite anomaly condition. The FE system proceeds down the list until the fault detection condition is cleared or the list is exhausted without affecting the availability of the FD system.</p> |
