| Abstract: | Aim at the problem that some navigation system can not fulfill the requirement of high precision in navigation and location. A new scheme based on federated filter in INS/GPS/DVS integrated navigation system is proposed using the dynamic information sharing coefficient method. When the information sharing coefficients of subsystems are optimized, integrated navigation system performance improved. Computer simulation was done and its results show that the scheme can effectively improve navigation system' s precision and the ability to fault detection and can fully distill information from navigation sensors. |
