Abstract

In order to improve the precision of Doppler and Strapdown inertial navigation system (SINS) integrated navigation system with moving base, an in-flight alignment method is proposed by making an uniform circular motion of the aircraft according to the phenomena avaliable in the Doppler/SINS navigation system tests. The platform error-angles of the SINS can be estimated quickly and the prediction precise can be improved by this method. Experiment verifies the feasibility and validity of this method. Theoretical analysis shows that the steady state limit of the estimation can be highly reduced by proposed method, and the method is valuable for practical application.
