| Abstract: | The selection of IGS reference stations in data processing of Jiangsu Continuously Operating Reference Stations network(JS CORS) was investigated in this paper.Firstly,high-precision data processing software GAMIT was briefly introduced.Then several processing strategies were designed.Numerical calculation showed that adding IGS reference stations located in Northern Hemisphere at high latitude would obtain better accuracy in the U-direction of baselines,while 3 to 4 IGS stations around CORS would achieve the accuracy of 2mm~6mm in the simultaneous solution. |
