| 摘 要： | 利用中国境内国际GPS大地测量和地球动力学服务(IGS)站的GPS单天数据,使用GAMIT软件对其进行基线解算.以单天解的基线结果作为输入量,利用所介绍的台站漂移数学模型,求解台站漂移速度,得到地壳运动信息;再根据板块运动欧拉定理,求解中国大陆整体的欧拉矢量.结果表明,在ITRF2000框架下,求解的台站漂移速度与IGS公布的结果相近,由此求解的中国大陆整体的欧拉矢量与采用IGS公布数据计算的结果相近.

| Abstract: | GAMIT is effective in GPS baseline solution.One of the outputs of GAMIT is H-file.It contains the covariance matrix and adjusted coordinates.In order to study global plate movement and regional crust deformation,the H-file is used as inputs,we consider the relationship between each sin-gle session solution.Thus we obtain the floating velocities of the used International GPS Service(IGS) stations.According to Euler theorem,we calculate Euler vectors of Chinese mainland.Analysis shows that the results are consistent with what given by the IGS. |
