Abstract: It focuses on the dynamic reliability assessment of navigation system. Firstly, the sampling criterion of the scenarios was studied based on the Monte Carlo simulation and the sampling criterion was given by calculating Shannon information entropy. Then the model of the dynamic reliability of navigation system was built based on SimPRA(simulation-based probabilistic risk analysis)and finished the dynamic reliability analysis. The results show that dynamic reliability assessment is advantage and effectiveness in engineering.
