| 摘 要： | 本文介绍了由IGS提供的关于电离层总电子含量TEC的数据文件IONEX,其包含的数据在时间和地理位置上是不连续的,利用插值方法计算不连续的时间和地理位置的TEC数值。运用MATLAB图形用户界面(GUI)的设计功能并结合其数据处理和绘图功能,设计关于GPS TEC数据处理的软件,按照区域(包括某特定地理位置)、时间为划分绘制TEC分布图或者变化图。通过实际应用,该软件的各功能界面能够独立运行并实现预期的数据处理和绘图等功能。

| Abstract: | The International GPS Service for Geodynamics （IGS） provides data files about the total electron content （TEC） of ionosphere with IONEX format （IONosphere map EXchange format）. However, the IONEX data files contains discontinuous both in time and geographic location. Corresponding interpolating methods are used to obtain continuous TEC data in sense of time and geographic location. A software for GPS TEC data process is developed by using MATLAB＇ s graphical user interface （GUI）. Through specifying time or region （a region or some specified point） , the software can draw the map of distribution or variation of TEC data. The practical applications show that each function of the software can be run independently and can achieve the expected functions. |
