Study and Experimental Analysis of Advanced RAIM Algorithm Based on BDS/GPS Multi-constellation

Receiver autonomous integrity monitoring (RAIM) is the key approach to monitor the integrity of global navigation satellite system (GNSS). The paper focuses on the RAIM algorithm based on multi-constellation. According analysis, the performance of ARAIM is validated. It is shown that Advanced RAIM method based on double constellations is effective for the users requiring high level of integrity, continuity, and availability. The performance of LPV-200 can be achieved.
