| Abstract: | Integrity analysis is an important part of the analysis of navigation system. The simulation verification and testing of integrity will reduce the technical risk of the system's development, it is an important issue in the domain of navigation simulation. The algorithms and models such as the arithmetic of RAIM and the availability of RAIM related to the simulation analysis of integrity based on the user receiver grid are proposed. Based on these, an integrity simulation analysis system of navigation system... |
