摘　　要：为提升卫星编队推力器故障检测能力,将研究重点前移至系统设计阶段,提出了一种基于信息几何的卫星编队星间链路拓扑设计方法。通过利用黎曼流形点描述不同故障模式下卫星编队测量信息特征,使检测能力量化问题转化为黎曼流形上各点间距离的度量问题。在此基础上,构建了卫星编队检测能力的度量指标,提出了卫星编队星间链路拓扑的设计方法,并通过仿真实例验证了所提方法的有效性。In order to improve the fault detection capability of satellite formations,an inter-satellite link topology design method based on information geometry is proposed in this paper. The measurement information characteristics of satellite formations under different fault modes are described by the Riemannian manifold points,and the problem of quantifying the system fault diagnosis capability is transformed into the problem of measuring the distance between the Riemannian manifold points. On this basis,the fault detection capability measurement index of satellite formations is constructed,and a design method of inter-satellite link topology for satellite formations is proposed. The effectiveness of the proposed method is verified by a simulation example.
