GPS/VISNAV integrated relative navigation and attitude determination system for ultra-close spacecraft formation flying

Abstract：For the improvement of accuracy and better faulttolerant performance, a global position system (GPS)/vision navigation (VISNAV) integrated relative navigation and attitude determination approach is presented for ultra-close spacecraft formation flying. Onboard GPS and VISNAV system are adopted and a federal Kalman filter architecture is used for the total navigation system design. Simulation results indicate that the integrated system can provide a total improvement of relative navigation and attitude estimation performance in accuracy and fault-tolerance. 作者： Author： Xiaoliang Wang  Xiaowei Shao  Deren Gong  Dengping Duan 作者單位： Institute of Aerospace Science & Technology, Shanghai Jiaotong University, Shanghai 200240, P.
