Abstract The wavelet transform theory and principle of wavelet denoising are discussed.Forthermore three different denoising method for GPS dynamic monitoring data denoising are analyzed. The experimental results show that the wavelet transform especial soft threshold denoising method is an effective method for the GPS dynamic monitoring data processing.It can improve the accuracy of monitoring data.
Key words ：
