Abstract:
As the probability of two-satellites fault simultaneously increase ,the difficulty of fault identification in the integrity monitoring become sever and the traditional RAIM(Receiver Autonomous Integrity Monitoring) may not proper to deal with this problem. This paper investigates the impact of two-satellites faults at the same time on integrity parameters. Two factors, two-satellites fault mode and range deviation combination ,are introduced to simulated the condition of two satellites fault at the same time in BeiDou, and the change of integrity parameters (Horizontal Positioning Error (HPE) and Vertical Positioning Error (VPE)) is discussed. The experimental results show that: under two-satellites fault condition, with range deviation increase, HPE and VPE grow. However, if the faulty satellite mode contains MEO and the range deviation is less than 100 meters, HPE/VPE shows little difference.
