| Abstract: | A hierarchical multistage and rescale information fusion method with fault detection,isolation and rescale for multi-sensor integrated navigation was put forward based on the INS/GPS/RDSS/Doppler/CNS in this paper.The model composition was given out,and the effect of the sequence of hierarchical multistage fusion and partial fusion on integrated estimation as well as the optimization were discussed. The theoretical analysis and simulation results showed that the integrated performance of the hierarchical multistage and rescale information fusion method was much better than that of rudimentary model of federated filter. |
