Summary:The accuracy of ERP solved by GPS technology is influenced by the selection of the station, the structure of the network and other factors. Accordingly, GPS data from IGS stations is downloaded to calculate ERP with a control variable method in order to analyze the effect of the number of stations and observation arcs on the accuracy of these parameters. The research shows that these two factors have a great impact on calculating ERP. In order to achieve optimum calculation efficiency and calculation precision, appropriate observation arcs should be selected according to the different station numbers.
