Abstract
High precision and good fault tolerance is of great importance in a navigation system.According to these requirements
an INS-GPS-DVL fault tolerance integrated navigation system scheme based on information fusion technology is presented.The filter algorithm of the system is studied.The system performance is studied by semi-physical simulation experiment.Simulation results show that the designed integrated navigation system may provide the navigation with high precision information
