【摘要】：利用PANDA软件计算2011-01~2014-10"陆态网络"所有基准站的单日解坐标,并采用QOCA软件解算基准站水平运动速度场。分析显示,PANDA软件水平定位精度达到2mm,且根据QOCA软件计算的"陆态网络"基准站水平运动速度场与中国地震局发布的速度场互差RMS在东西、南北方向分别为1.12mm/a、0.95mm/a,表明计算结果准确、可靠。在此基础上,基于速度场数值结果描述了中国大陆相对欧亚板块的水平运动速度场的空间分布特征。
[Abstract]:The single-day solution coordinates of all datum stations in 2011-01 / 2014-10 "land state network" are calculated by using PANDA software. The horizontal moving velocity field of the reference station is calculated by QOCA software. The analysis shows that the horizontal positioning accuracy of Panda software reaches 2mm, and the horizontal velocity field of the "land network" reference station calculated by QOCA software and the speed issued by China Seismological Bureau. The degree field difference RMS is in the east and west, The north and south directions are 1.12 mm / a 0.95 mm / a respectively, which shows that the calculation results are accurate and reliable. Based on the numerical results of the velocity field, the spatial distribution characteristics of the horizontal velocity field of the Chinese continent relative to the Eurasian plate are described.
