摘要
电离层是影响卫星导航系统传输时延的重要因素之一,电离层总电子含量(TEC)地图重构是消除电离层传输时延的重要手段。GPSTk作为GPS数据处理的重要软件之一,可以满足区域电离层TEC地图的重构要求。本文针对GPSTk的特点,深入研究了GPSTk的电离层TEC计算原理、数据处理流程及具体的软件操作方法,该研究对基于GPS数据的电离层数据处理软件的研制具有一定的参考意义。
Ionospheric delay is one of the most important resources in satellite navigation systems,and TEC map reconstruction is the major way to eliminate the delay effect of the satellite navigation systems.As an important tool for GPS data processing,GPSTk software can be used to fulfill the requirement of the TEC map reconstruction.Based on the analysis of the characteristic of GPSTk,the principle of the TEC calculation,the flowchart of the data processing and the operational approach of the GPSTk were demonstrated in this paper,which will be helpful in the development of the GPS-based software for ionospheric data processing.
