| Abstract: | Autonomous navigation is the key technology of spacecraft autonomous operation, while state estimation, the core means of spacecraft autonomous navigation which refers to the real-time determination of spacecraft orbit position, velocity, attitude and other navigation parameters, is one of the key development directions of the spacecraft autonomous navigation technology. Aiming at the practical requirements of the spacecraft autonomous navigation, this paper illustrates the necessity of studying spacecraft autonomous navigation state estimation method and introduces its research status from three aspects, including observability analysis of the navigation system, the navigation filtering algorithm, and error compensation of the navigation system. Then practical applications of the state estimation method in the spacecraft autonomous navigation system is analyzed and summarized. Finally, based on theoretical research and practical applications, the main problems of the state estimation method are presented and the future developments are prospected. |
