Abstract:	GNSS anti-spoofing techniques become more and more important with the popularization of positioning and navigation applications. Compared with other complicated anti-spoofing techniques, Receiver Autonomous Integrity Monitoring (RAIM) does not impose extensive hardware modifications to the receiver, it is a feasible and effective way to detect and mitigate single spoofing signal. RAIM’s potentiality to deal with more than one spoofing signal is researched in this work. A recursive RAIM technique for detecting and mitigating more than one spoofing signal without other independent information is proposed in this paper. The method’s performance analysis and evaluation is provided as well. Simulation results are provided to demonstrate the effectiveness of the solution.
