摘要
采用克里金插值法和常用插值方法内插IGS电离层图数据,获得重庆CORS网5个基准站电离层穿刺点处的VTEC值,和利用5个基准站的GPS平滑伪距观测值解算的VTEC值进行比较,发现克里金插值法和常用插值方法的内插精度相当,故克里金插值法内插IGS电离层图的精度是可靠的。
Through interpolating IGS ionospheric maps adopted Kriging interpolation method and conventional interpolation methods,the vertical total electron contents（VTEC）of the five base stations in Chongqing CORS are obtained.Comparing the interpolation results to the VTEC with GPS smoothed pseudo-range observations of the five base stations,it is found that the accuracy of Kriging interpolation method and conventional methods is approximately equal,which is proved that Kriging interpolation method can be adopt to interpolate the IGS maps,and its accuracy is reliable.
