摘要
本文介绍了由惯性器件、GPS姿态传感器、太阳敏感器、地球敏感器组成的卫星姿态测量系统 ,利用联邦滤波器对载体姿态进行分散化估计 ,计算机仿真表明该方案不仅有与集中滤波器相当的精度 ,且容错性好。在本文给出的系统中 ,选取不同的信息分配因子进行联邦滤波器的设计 ,可以获得不同的子滤波器性能 ,以利于故障诊断。
In this paper, a satellite attitude measurement system which consists of inertial device, GPS attitude sensor, solar sensor and earth sensor is presented. The dispersing estimate of attitude using federated filter is carried out, the simulation result of this estimate shows that the federated filter has not only the same precision as centralized filter, but also good fault tolerance. In this estimate system, different information distributing factors are used in the design of the attitude estimate system, therefore, different performances of subfilter are obtained. It is very useful for fault diagnose.
