A New Algorithm for GPS Receiver Autonomous Integrity Monitoring Based on Quasi-Accurate Detection of Gross Errors

摘要：

The Least Squares residual and the parity space methods are the popular methods used for Receiver Autonomous Integrity Monitoring (RAIM), which are proposed for single failure. The two methods are not suitable for the situation of multiple gross errors, so that the more and more attention has been paid to the related researches. This paper proposed a new algorithm for GPS RAIM based on Quasi-Accurate Detection of gross errors. It detects and identifies abnormal observations based on real errors of QuasiAccurate Observations, which performs well for single and multiple failures. The proposed algorithm is verified by a numerical example.
