FILTERING OF SHIP'S STRAP-DOWN GYROSCOPE SIGNALS BASED ON WAVELET ANALYSIS
Xie Rong · Harbin Gongcheng Daxue Xuebao/Journal of Harbin Engineering University · 2001
Presents the implementation of multiscale wavelet decomposition of gyroscope output by using four_order Daubechies wavelet,which provides good multiresolution performance for signals,and decreases the noise significantly and concludes from simulation results that this method can therefore improves the aligning precision and shortening aligning interval.
