Inertial Navigation And Integrated Navigation And Simulation

In this paper, the main navigation methods and the principle of SINS navigationare introduced. According to the principle of SINS, it calculates and simulates the observations of SINS through prearranged track, deduces the error equations of initializing alignment of SINS, simulates the process of alignment. This paper researches the technique of multi-sensor fusion to a certain degree, according the principles of SINS and other navigation methods, designs a project of combining navigation of SINS/GPS/DS, deduces the model equations of combining navigation and simulates the process, the result shows that the precision of result with federated filter is higher than that of sub-filter. In this paper, GPS/DR combining navigation arithmetic is studied, using VC++ and MapX widget a software system on GPS/DR combining navigation is wrote, and several experimentations are made using this software system.
