摘要
对以往GPS数据转换软件存在转换效率低、数据质量差等进行了研究,提出在LINUX环境下用CSHELL语言编写的一站式批量转换方法,将原始观测数据t00/t01/t02转换成.tgd格式,再转换成标准的RINEX格式文件。实验结果表明相比常规方法,本文提出的方法转换时间缩短至10%,且P2数据流能得到很好地保留,为后期数据处理提供质量保障。
We have studied the problems of low conversion efficiency and poor data quality in the past GPS data conversion software,a integrated batch conversion method written with C-SHELL language under LINUX environment is proposed. The method of converting raw observation data from t00/t01/t02 into.tgd format,then convert it into standard RINEX file. The experimental results show that compared to the conventional methods,the conversion time is shortened to 10%,and the P2 data stream can be well preserved,which provide the quality guarantee for the latter data processing.
