EVALUATION OF TEC FROM NNSS SATELLITES DATA
-
摘要: 论述了应用色散多普勒技术,在求解测站上空大面积TEC的方法中,卫星相对测站径向速度变化对电离层产生的微分多普勒频移的影响,找到了比较好的修正方法,并对若干测量计算结果进行了由定性到定量分析,绘出了测站上空任一点TEC的日变化曲线。

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. -
