| Abstract: | A method of precise integrated navigation based on strapdown inertial navigation system (SINS) is researched. The system errors of SINS were chosen as states of the integrated navigation system. The attitude matrix output from celestial navigation system (CNS) and the equivalent attitude matrix calculated by outputs of SINS were taken to construct the observation, and the algorithm of SINS/CNS integrated navigation is designed. The position outputs from SINS and radio determination satellite service (RDSS) ... |
