| 摘 要： | 经过多年观测与积累，GNSS站数据已形成大数据规模，面对大区域、多年GNSS观测数据，需研究数据质量检测方法，形成快速、常态化检测机制，为GNSS站观测数据快速提取与推广应用提供质量保障。本文提出了一种基于TEQC技术的GNSS区域站观测数据质量检测方法，分析了检测内容、检测方法及方法关键点；以大华北区域660余个站点10期观测数据为研究对象，采用所提出的方法，对其进行质量检测，并对检测结果进行了分析；通过实地考察站址观测环境，分析了误差超限的原因，从而修订了观测工艺流程；基于研究成果构建了适用于大规模GNSS站观测数据质量检测技术体系，可为全国GNSS站观测数据质量检测提供方法参考。

| Abstract: | After years of observation and accumulation, GNSS data have formed large data scale.Facing large area and multi-year GNSS data, we need to study the data quality detection method to form a fast and normalized detection mechanism to provide quality assurance for GNSS data rapid extraction and application.In this paper, a method of quality detection for GNSS regional station observation data is proposed based on TEQC technology, the detection content, detection method and key points of the method is analyzed.we use the method to complete the 10 stages data quality detection of more than 660 stations in the North China.Experimental results show that the method can be applied to the quality detection of large-scale GNSS stations, which can provide a reference for the national GNSS station data quality detection. |
