Methods of Public Information Sharing in Federated Filter
Zhang Zong-lin · Fire Control and Command Control · 2006
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 informationsharing 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.
