【摘要】：推导引入新的归心基线的ITRF组合解算公式,分析陆态网络归心基线对ITRF2008中坐标及其速度的影响。结果表明,在ITRF2008中引入陆态网络中长春、昆明和乌鲁木齐3个并址站2011年观测得到的归心基线及其协方差阵的解算成果,与ITRF2008结果相比,绝大多数站点的坐标差值小于10mm,坐标速度差值小于1mm/a;绝大多数站点的水平速度场和垂直速度场与ITRF2008速度场保持一致。
[Abstract]:A new formula of ITRF combination solution for centring baselines is derived, and the influence of land-based network centring baselines on coordinates and their velocities in ITRF2008 is analyzed. The results show that the calculated results of the centroid baseline and its covariance matrix observed by Changchun, Kunming and Urumqi stations in 2011 in ITRF2008 are compared with those obtained by ITRF2008. The coordinate difference of most sites is less than 10 mm and the coordinate velocity difference is less than 1 mm / a. The horizontal and vertical velocity fields of most stations are consistent with the ITRF2008 velocity field.
