Abstract: In this paper, a method to improve the determination of Total Electron Content (TEC) using the measured differental data of NNSS satellites in a large range above a station is presented' At the same time, several measured and calculated results are analysed qualitatively and quantitatively. The diurnal TEC change curves can be given at a large range of positions above a station.
