Abstract
The existing Receiver Autonomous Integrity Monitoring (RAIM) algorithms for multiple faults have problems to determine the number of faults with high efficiency. To solve the problem, a multi-constellation RAIM method for multiple faults is proposed in this paper. By establishing the distribution of likelihood probability under different fault modes, the faults with unknown number of faults can be identified. The simulations with BDS/GPS/Galileo show that our approach can effectively identify fault satellites in both the single-fault scenario and the multi-faults scenario.
