摘要
目前的导航系统多采用以惯导为主的组合导航方案,其组合算法有集中卡尔曼滤波和联邦卡尔曼滤波两种。针对联邦滤波器公共信息分配的问题,分析了常规的固定分配系数的方法及其特点,之后详细讨论了动态分配方案,列出了几种分配模型。最后给出了IN S/GPS/ADS组合导航系统公共信息动态分配的算例。
At present, the navigation systems almost adopt the integrated system based on the inertial navigation system. The integration algorithm is centralized or federated filter algorithm. In allusion to the problem of sharing the common information of the federated filter, this paper analyses the routine fixed information-sharing method and its characters. Then the dynamic information-sharing method is discussed and several sharing models are listed. At last, an actual example of a n INS/GPS/ADS integration system using the dynamic information-sharing method is provided.
