摘　　要：全球卫星导航系统(GNSS)观测值的数据质量是保证GNSS高精度定位的前提,为提高数据质量需要对GNSS观测值进行数据预处理,目前应用较为广泛的是UNAVCO Facility机构开发的TEQC软件.由于TEQC是DOS环境下的命令式,没有图形操作界面,人机交互性较差,生成的绘图结果文件需要借助QCVIEW等可视化软件处理,但这些软件尚无法对TEQC 2013.3.15以上版本生成的compact 3格式文件进行图形分析.因此,本文基于MATLAB GUI开发了一套适用于compact 3结果文件的可视化界面软件(TEQCplot View),实验测试结果表明:该软件性能稳定,可实现对不同结果文件的可视化分析.The data quality of GNSS observations is the premise of ensuring high-precision positioning of GNSS.In order to improve data quality,data preprocessing of GNSS observations is required.Currently,TEQC software developed by UNAVCO Facility is widely used.However,TEQC is an imperative in DOS environment,there is no graphical user interface,and human-computer interaction is poor.The generated drawing result files need to be processed by visual software such as QCVIEW,but these saftwares can not conduct graphical analysis of the compact 3 format file generated by TEQC 2013.3.15 or higher version.Therefore,based on MATLAB GUI,a set of visual interface software(TEQCplot View)for compact 3 result files is developed.The experimental results show that the software has stable performance and can realize visualization analysis of different result files.
