This paper proposes a reliability assessment method for Receiver Autonomous Integ-rity Monitoring(RAIM).Probability limit state model offers tools for fault detection with the consideration of the Required Navigation Performance (RNP)parameter and uncertainty noise, while navigation system integrity by dual index system is established by safe coefficient com-bined with reliability coefficient and reliability coefficient is given to evaluate the system integ-rity.The dual index system evaluation criteria,which can be used to monitor the system integ-rity efficiently,is described.Simulation for Non-Precision Approach (NPA)validates both the viability and the effectiveness of the proposed method.
