Based on observational data of 8 continuous GPS site in Anhui and adjacent areas,this paper used principal component analysis method to extract the common mode errors,and deducted the residual time series of common mode error before and after a comparative analysis.The results show that the cyclical changes of the residual time series after deduction of the common mode errors are more obvious.And the data signal to noise ratio is improved.
