Abstract: This paper separates and distills the multipath model from three directions residual coordinate of X,Y,Z based on complete empirical mode decomposition (CEEMD). We use the repetition characteristics of multipath to correct the coordinate sequence for the next day. The results show that, CEEMD can effectively extract the multipath error correction model from residual coordinate, and the RMS of coordinates sequence after correction is much smaller than before. This signifies that the method weakens the influence of multipath error to a certain extent. Furthermore, the processing result is superior to the traditional moving average de-noising method and EMD.
