APPLICATION OF WAVELET AND KALMAN FILTERING COMBINATION IN GPS CYCLE SLIP DETECTION AND RESTORATION
小波和Kalman滤波组合在GPS周跳探测与修复中的应用

GPS Double-difference observations were decomposed through wavelet analytical method and the areas where biggish perturbation will occur were determined by the reconstructed high frequency signal.According to the theory and method of Kalman filtering,then the observations of iffy areas were detected and corrected for cycle slip.The results indicate this method can repair small cycle slip primely,and has a good result for continuous cycle slips.
