2015年7月-2017年4月京津冀地区22个GNSS连续观测站点的年均形变速率测量数据

GNSS形变测量数据1组，对研究区内22个GNSS连续观测站点进行长时间精密定位静态解算，获取三维坐标时间序列，进一步利用时间序列分析方法，在剔除粗差、干扰等因素后，计算获得每个点位的水平向和垂直向年均形变速率，用于InSAR地形变监测结果的验证。水平向形变速率观测精度在1-3mm/a,垂直向形变速率观测精度在3-5mm/a。

A set of GNSS deformation survey data: Twenty-two continuous GNSS observation stations within the study area underwent long-term precise positioning static solution to obtain three-dimensional coordinate time series. Subsequently, after eliminating gross errors and interference factors via time series analysis methods, the annual mean deformation rates in the horizontal and vertical directions for each station were calculated, which are used to validate the results of InSAR terrain deformation monitoring. The observation accuracy of the horizontal deformation rate is 1-3 mm/a, and that of the vertical deformation rate is 3-5 mm/a.
