A multi-scale information fusion estimation method based on wavelet filtering is presented in this paper. The method of signal multi-scale analysis and of multi-sensor information fusion technology have been combined, and used for the process of integrated navigation. The performance of system is also established, based on different `scale' which could break the restriction of single scale one. The deficiency of regular filter estimating methods in dealing with high-frequency slowly time-varying noise is improved to some extent. Simulation results verified that multi-scale method used in integrated navigation could improve the precision and provide theory foundation for possible application of practical system.
