Abstract :
The Receiver Autonomous Integrity Monitoring (RAIM) is used to improve positioning system safety. This paper proposes a new RAIM approach to detect and exclude multi-faults of GNSS measurements before position estimation. The new approach uses the information filter for position estimation and information test to faults diagnosis. This test is based on exponential convergence of the information filter measured using the mutual information. Results with real data of GNSS measurements (C/A code and L1 phase) show the benefits of the proposed approach in improving the GNSS receiver integrity positioning.
