东北亚地区GPS观测数据质量检测和分析

Quality Checking and Analysis on GPS Data in Northeast Asia

利用TEQC软件对东北亚地区52个GPS台站4 a的观测资料进行了质量检测,给出了这些站的数据质量报告,并按照IGS的质量标准对这些数据进行统计分析。结果表明,90%以上的台站观测数据质量(CSR<10,MP1<0.5,MP2<0.75)好于全球IGS站的资料质量状况。

In this paper, the quality of GPS data with four-year observation span on 52 stations is checked with TEQC software. The result of data quality checking is given, and is statistically analyzed according to IGS data quality status. It is shown that over 90% of GPS stations have high qualities （with CSRG10, MP1G0.5, and MP2 〈0.75）, which is better than the quality status of IGS stations.
