| Abstract: | Wavelet packet analysis was adopted to filter th e output signal of ring laser gyroscope(RLG)in order to reduce the influence t o the alignment and navigation precision of the RLG strapdown inertial navigatio n system(SINS).The filtering effect in the practical system has been contrastiv ely investigated with the exploited evaluating software.Filtering result shows that the filtering method of wavelet packet analysis is simple and applied,and it is especially fit for processing the signals of RLG,and it can enhance align ment and navigation precision greatly. |
