| Abstract: | As to GPS station coordinate residuals,we used two classical ARMA modeling methods(Box-Jenkins method and Pandit-Wu method) to fit the GPS station coordinate residuals,and made comparative study.According to the experiment,we found out that the two methods have a little difference while there is abundant data.If the data is poor,with the Pandit-Wu method the results will be better.The amplitude of residuals reduces about 13 and the distribution is more uniform. |
