N2 - The Global Positioning System (GPS), Inertial Navigation System (INS) technologies both play very important roles in navigation systems. Ultra-tight integration offers numerous advantages including increased robustness under high dynamics, and improved anti-jamming performance. It can be applied to integrity monitoring, which is an elementary performance of flying security in the field of aeronautics and astronautics. This paper introduces an integrity monitoring algorithm based on ultra-tight configuration. The ultra-tight configuration is realized by the way of INS-aided GPS tracking loops. With the information from INS, the tracking performance can be improved since the tracking loop parameters can be optimized beyond the GPS-only case. The test statistics is given by the Kalman filter residual based on the ultra-tight filter. A rate detector configuration is used in integrity monitoring process based on the ultra-tight configuration. In the end of this paper, the simulated high dynamic flight test results of ultra-tight integration based on the Kalman filter are presented, and the results showed that this algorithm can get better performance in integrity monitoring.
