| Abstract: | In this paper, information structure of INS/CNS/GNSS integrated navigation system is analyzed. It is pointed out that federal filter used to estimate states can cause inopportune information fusion under this case. In order to solve the problem, several structures of bogus federal filter are designed and information structure, distribution and fusion of designed filter is analyzed, and the concept of bogus federal filter is proposed. The problem discussed in the paper and the design of bogus federal filter can be applied in similar multi sensors information fusion system. |
