摘　　要：在铁路线路工程平面控制网卫星定位测量中,需要将大量GNSS接收机原始观测数据转换为与接收机无关的RINEX格式文件,以天宝GNSS接收机观测数据为研究对象,采用C#语言对该公司提供的GNSS接收机原始观测数据解码程序Convert To RINEX进行二次开发,分析该程序的批处理文件语法规则,然后基于批处理文件调用Convert To RINEX程序的方式,编制天宝GNSS观测数据批处理程序。工程实践表明,该批处理器软件能够方便快捷地将海量原始数据批量转换为RINEX格式文件,极大地节约卫星定位测量数据处理工程中数据预处理所需时间,显著提高了生产效率。In order to solve the problem of converting a large amount of original GNSS receiver observation data into RINEX format files independent of the receiver during satellite positioning measurement in railway line engineering plane control networks,this paper used the C#language for secondary development of the program.The GNSS receiver observation data of Trimble Company was taken as the research object,and the syntax rules of the batch processing file of the GNSS receiver original observation data which provided by the company decoding program Convert To RINEX were analyzed.Then,the batch processing file calling method of the program was used to develop the Trimble GNSS observation data batch processor.After engineering verification,this batch of processor software could conveniently and quickly convert the massive raw data of Trimble GNSS receivers into RINEX format files independent of the receivers,and can be applied to various large-scale satellite measurement projects such as railway line engineering plane control network satellite positioning measurement.
