The observation material of monitoring points in GPS deformation monitoring system is the time-related signal sequence.It is the analysis of data sequence of monitoring points obtained from Sutong bridge GPS deformation monitoring system using wavelet analysis optimization processes in the paper.The results showed that choosing the appropriate wavelet basis function,wavelet decomposition and reconstruction of the data signals could effectively extract useful signals of features from the monitoring data sequence interfered by strong noise,which would help solve the limitations of traditional solving technology in de-noising GPS dynamic observation data and extraction of feature information.
