| Abstract: | In this paper, a wavelet oriented de-noising method is applied in the de-noising of GPS double-differenced observation series. The application results show that the wavelet de-noising principle can effectively eliminate noise disturbance from GPS observation series polluted by strong noise, extract the useful information, which greatly improves the validity of baseline processing, enhances the accuracy of GPS and also solves the limitation of GPS dynamic monitoring caused by traditional technology. |
