TEQC绘图辅助工具的设计与实现

为解决由于TEQC软件生成的plot文件数据格式升级为COMPACT3格式,原有绘图辅助工具QCView、cf2ps、qc2sky以及用户定制工具等都无法正确读取plot文件,无法正确绘制数据图表的问题,本文基于MATLAB编制出teqcplot3程序,读取COMPACT3格式的plot文件,绘制相应的图表,并用实测数据对该程序进行测试。结果表明:该程序可支持GPS、GLONASS和BDS卫星的数据,同时能够兼容COMPACT、COMPACT2和COMPACT3格式,结果正确可靠。本文的研究成果为TEQC软件提供了有效辅助绘图工具,为TEQC软件的使用和GPS数据预处理提供了有力支持。

Design and Implementation of TEQC Drawing Auxiliary Tool

In order to solve the problem that the plot file data format generated by TEQC software is upgraded to COMPACT3 format,qcview,cf2ps,qc2sky and other user customized tools cannot read the plot file correctly and draw the data chart correctly,this paper developed a program named by teqcplot3 based on MATLAB.It can read the plot file of COMPACT3 format,then draw corresponding chart.The program is tested with the measured data and the results shown that the program supported the GPS,GLONASS and BEIDOU satellite data,it can also out could be compatible with COMPACT,COMPACT2 and COMPACT3 formats,and the functions were correct and reliable.It provided an effective assistant drawing tool for TEQC software,and support for the TEQC software and GPS data pre-processing.
