TEQC结合RTKLIB软件检核GPS观测数据质量

Quality Checking of GPS Observation Data Using TEQC Combined with RTKLIB Software

阐述了GPS观测数据质量的检核方法、原理及主要评价指标.介绍了TEQC和RTKLIB软件在数据质量分析方面的功能,利用实测GPS数据进行质量分析对比可得出:1)TEQC基于DOS环境运行,人机交互性差,RTKLIB软件运行于Windows系统,操作便捷;2)二者数据质量的主要评价指标结果完全一致;3)RTKLIB软件可对卫星可见性、天空视图、DOP值进行图形化显示,但无电离层延迟误差、电离层延迟变化率和卫星方位角绘图功能;4)将TEQC与RTKLIB软件结合可相互弥补,全面、直观地分析观测数据质量,达到很好的分析效果。

This paper elaborated the GPS observation data quality checking method, rinciple and main evaluation index, and introduced the TEQC and RTKLIB software in the ata quality analysis function. By GPS data quality analysis and contrast to each other, We found that ： 1） TEQC RTKLIB software runs valuation index KLIB software results runs in DOS environment, with poor man in Windows system, which is convenient t of the data quality of the two are complete can display the ionospheric delay error, ionos machine interaction, o operate. 2） the mai ly c satellite visibility, sky map and DOP val pheric delay rate of change or satellite a bined TEQC with RTKLIB software can help to comprehensively and observation data quality, With a good analysis effect onsistent;3） the RT ue graphically, but no zimuth map; 4） corn intuitively analyze the
