摘要
在对RLV(Reusable Launch Vlehicle,可重复使用航天运载器)的轨道特性进行详细分析的基础上,提出了RLV导航系统的硬件分段配置方案.针对RLV对导航系统高容错性、动态适应性和智能化水平的要求,提出了基于动态贝叶斯网络理论的容错式组合导航信息处理方法.利用基于动态贝叶斯网络理论的传感器动态选择控制器,实现传感器件组合的动态自主优化配置和系统实时健康监控.
Through the research on orbital characteristics of RLV （Reusable Launch Vehicle）, navigation device design scheme on different orbital sections is put forward. In allusion to requests of higher fault tolerant property, intelligentized level and dynamic ability, an integrated navigation information processing method based on DBNs theory with fault tolerant capability is proposed. By dynamic selective DBNs controller for navigation sensors and their combination, active and dynamic optimal deployment and real time health monitoring are achieved.
