摘要
目前尚无一种GNSS数据质量检测软件可以兼容RINEX格式第二版和第三版、同时兼容四大导航卫星系统,严重滞后于GNSS的发展。基于MATLAB语言研发了一种新的数据质量检测软件BQC,不仅可以处理单观测文件,还可以对多个观测文件进行批处理;可以输出四大导航卫星系统的卫星角度位置、多径误差、电离层延迟、载噪比和周跳等信息及统计报告,在批处理模式下还可对多观测文件的数据质量进行比对;与TEQC相比具有较强的兼容性、算法优越性和直观性。随着四大导航系统的逐步完善和RINEX格式第三版的推广使用,该软件将会为GNSS的建设成果检验工作提供一种有力的支撑工具。
A novel GNSS data quality check software BQC is developed on MATLAB which can process data of four dominant naviga- tion satellite systems - GPS, Beidou, GLONASS and Galileo - and data recorded in RINEX format version 2 and 3. BQC can work in two modes： single -file processing mode and batch processing mode. It generates satellite angle position, multipath error, ionosphere delay, SNR, carrier phase slips, as well as a summary report ; in addition, data quality of different observation files is compared and shown in figure files in batch processing mode. It is shown in this paper that BQC has better compatibility, algorithm priority and visu- alization than TEQC. With the development of GNSS and popularization of RINEX format version 3, BQC is going to be a powerful toolkit for GNSS construction result check.
