Example Analysis of Ionosphere Delay Correcting

介绍了利用双频GPS观测值建立电离层模型的原理和方法;利用某地的双频GPS观测资料分析了VTEC的变化。

It introduces the ionosphere models,and the principle,the methods of establishing the ionosphere models with GPS dual frequency measurements.In addition,the data of the total electron content in the vertical direction（VTEC） at an example is analyzed in this paper.
