摘　　要：GNSS数据预处理是实现高精度导航、定位和姿态应用的重要环节.针对当前GNSS预处理工具和模块难以处理多频多系统观测数据的问题,研发了一款GNSS数据预处理软件(GNSS data preprocessing software,GDPS),包括数据下载、格式转换、数据编辑、质量检核和辅助工具等模块,并通过PYQT5工具实现了软件图形用户界面的开发.实验测试结果表明:该软件界面清晰,界面交互性较强,模块运算稳定,软件功能完善,可满足不同用户对多频多GNSS观测数据预处理的需求.GNSS data preprocessing plays a crucial role in achieving high-precision navigation,positioning,and attitude applications.However,existing GNSS preprocessing tools and modules face challenges in handling multi-frequency and multi-GNSS observation data.To address this issue,we have developed a GNSS data preprocessing software called(GDPS).GDPS includes modules for data download,format conversion,data editing,quality check and auxiliary tools.The software has been implemented using the PYQT5 tool,which enables a graphical user interface.Experimental tests have demonstrated that the software offers a clear interface,strong interactivity,stable module operation,and comprehensive software functions.Consequently,it effectively caters to the diverse needs of users for preprocessing multi-frequency and multi-GNSS observation data.
