| 摘 要： | 通过处理重庆CORS网的5个基准站观测数据,获得5个基准站上空电离层垂直总电子含量(VTEC)。利用其中的4个测站上空的VTEC采用克里金插值和反距离加权插值内插出另外一个测站上空VTEC。将插值结果及广义三角级数函数模型计算的电离层VTEC与实测VTEC进行比较,发现克里金插值和反距离加权插值的精度比广义三角级数函数计算的精度更高,更稳定;且克里金插值精度高于反距离加权插值。

| Abstract: | Through processing of Chongqing CORS network five reference station observation data ionosphere verti-cal total electron content VTEC of the five base stations are obtained. The VTEC of the four stations are interpo-lated another station VTEC adopting Kriging interpolation and reverse distance weighted interpolation. Compared the interpolation results to the modeling results of generalized trigonometric series function to VTEC obtained from GPS observation data it is found that the accuracy of Kriging interpolation and inverse distance weighted interpola-tion is higher than the generalized trigonometric series function simulation and more stable. And the interpolation accuracy of Kriging is higher than inverse distance weighted. |
