Application of Wavelet Analysis on FOG North Seeking
Abstract：FOG measurement data from experiments were analyzed in this paper. To reduce the impact of noises on the FOG north-seeking and improve the precision of north seeking. Filter was carried on using three smoothness every five points,digital filter and the wavelet analysis method to the FOG static output, through contrasting around the FOG output curve, the standard deviation as well as spectrum graph, it can be concluded that wavelet threshold filter compensates effectively the FOG random error. The trend of low frequency signal in FOG can be shown by the wavelet analysis. Using de-noised data, two-position north seeking was computed. The results of experiments show that wavelet analysis can increase the precision hv ？.9 8
