摘要
在数据处理或固定监测站选址时,甄别GNSS原始观测数据的好坏,评估观测数据的质量是十分必要的。利用TEQC软件检查GNSS观测数据的质量,生成的电离层延迟、多路径效应、信号噪声比、卫星方位角、卫星高度角等相关内容的文本文件。基于C#语言开发了TeqcChart(V1.0)程序,用于读取上述文本文件,开发了功能丰富的图形绘制模块,图形显示效果好、运行速度快、自动化程度高、使用简单。该软件在自动化监测系统和连续运行卫星参考站系统(CORS)中进行了初步试用,效果良好。
In the data processing or selection for fixed station,it is essential to judge the quality of GNSS observation data.The software of TEQC can check the quality of GNSS observation data,and generate the files for ionospheric delays,multipath effect,signal-noise ratio,satellite azimuth,satellite elevation angle and other related contents.We develop a software of TeqcChart（V1.0） based on the C # language.TeqcChart can import the above text files,and produce feature-rich graphics for GNSS quality check files.These graphics are outstanding,the software runs fast and it＇s easy to use.The software has been used in the automatic monitoring system and Continuously Operating Reference Station System（CORS）,which produces good effect.
