克里金插值法内插 IGS 电离层图精度分析
Analyse the Interpolation Accuracy of IGS Ionospheric Maps Using the Kriging Interpolation Method
摘要
Abstract
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 re‐sults 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 ap‐proximately equal ,w hich is proved that Kriging interpolation method can be adopt to inter‐polate the IGS maps ,and its accuracy is reliable .关键词
