摘要:
针对目前关于GEO卫星自主导航方法中存在的精度低、成本高、实现复杂、可行性一般的问题,提出了一种基于多天体目标信息实现GEO卫星自主导航的方法。使用星敏感器敏感恒星信息和紫外地球敏感器敏感地球信息,建立了高精度GEO轨道动力学模型,并设计了EKF算法、UKF算法以及MCMCUPF算法进行导航解算。理论分析和仿真验证表明,提出的方法精度高、实现易,是一种切实可行,有效的卫星自主导航方法。

Abstract:
It devotes to the research of GEO satellite autonomous navigation, aimed at the problems which exist in the present methods of low accuracy, high cost, complexity and poor feasibility, then put forward a new method for GEO satellite autonomous navigation based on multi-celestial information. Through the theoretical analysis and simulation show that the proposed method in this paper is high precision, low cost and easy to realize. It is a feasible and effective method for satellite autonomous navigation. Use the star sensor to sense the star information and the ultraviolet earth sensor to sense the earth information and design EKF algorithm, UKF algorithm and MCMCUPF algorithm for navigation calculation. Through the theoretical analysis and simulation show that the proposed method in this paper is high precision, low cost and easy to realize. It is a feasible and effective method for satellite autonomous navigation.
Key words:  GEO satellite  autonomous navigation  star sensor  ultraviolet earth sensor  EKF/UKF  particle filter
