摘要
为了得到比较"干净"的观测数据或者提高整体观测数据的质量,通常需要对GPS(Global Positio-ning System)观测数据进行预处理。一般的随机处理软件会因为GPS接收机型号的不同而不能对任意的GPS观测数据进行预处理,而TEQC(Translation,Editing and Quality Checking)和QCVIEW32(QualityChecking VIEW32)可以对任意的GPS观测数据进行格式转换,去除噪音等预处理操作。本文分析了GPS观测数据预处理的现状,总结了TEQC和QCVIW32在GPS观测数据预处理中应用的优点和缺点,介绍了TE-QC和QCVIW32的用法,利用VB6.0(Visual Basic 6.0),结合TEQC和QCVIW32的优点,针对TEQC和QCVIEW32依赖dos环境,人机交互性差等缺点,编写了GPS观测数据预处理可视化程序TEQCAST。通过实例分析,证明该程序操作简便,并且能够使预处理后的数据质量得到显著改善。
In order to obtain more accurate data to improve the quality of the GPS observations,the observation data of Global Positioning System（GPS） usually need to be pre-processed.Different from the common random-processing software,Translation,Editing and Quality Checking（TEQC） and Quality Checking VIEW32（QCVIEW32） can pre-process arbitrary GPS observation data no matter what model the the GPS receiver is.This paper analyses the current situation of GPS observation data pre-processing,summarizes the advantages and disadvantages of TEQC and QCVIEW32 applied to the GPS observational data,and also describes the usage of TEQC and QCVIW32.Aiming to avoid the disadvantages of TEQC and QCVIW32（such as dependence on DOS,poor human-computer interaction,etc.）,the authors of this paper uses VB6.0 to write TEQCAST,a visual program for the pre-processing of the GPS observational data.Through practical examples,it is proved that TEQCAST is simple and easy to operate,and also can improve the quality of the pretreated observational data significantly.
