Abstract

Based on global positioning system (GPS), the horizontal positioning level (HPL) and the availability of receiver autonomous integrity monitoring (RAIM) were analyzed. According to the navigation performance requirements of aviation users, the factors which affected the availability of RAIM were simulated. Simulation results show that RAIM availability decreases with the decreasing of probability of false alarm, when the probability of missed detection is constant. And RAIM availability decreases with the decreasing of probability of missed detection,  when the probability of false alarm is constant. With the decreasing of cutoff angle and the increasing of visible satellite numbers, the RAIM availability becomes higher. The results can provide some reference for application of GPS RAIM algorithm to detect and isolate fault satellite.
