Single epoch GPS deformation monitoring data processing method without ambiguity and cy?cle slip problem can quickly extract the information of monitored deformation, especially suitable for the deformation monitoring of project with short baseline and high precision whose deformation is tiny. Wavelet multi-scale analysis method is applied to outlier detection and noise reduction of GPS deforma?tion monitoring. The tiny deformation characteristics is extracted effectively and the precision of GPS de?formation monitoring is enhanced. The analysis on GPS deformation monitoring data of Hanyuan new county validated the correctness, validity and reliability of this method.
