在其作为ITRS组合中心的职能中,DGFI开发了精确的地球参考框架计算方法。先进的方法是基于历元正常方程(每周/每日数据集)的组合,包含站的位置和地球定向参数(EOP)从不同的大地测量空间技术,如VLBI,SLR,GPS和DORIS。这种改进的方法允许考虑非线性效应(例如,周期性信号和不连续性),并确保TRF和EOP之间的一致性。ITRF 2004提交的资料被用作完善实现地球参考框架的投入。本文介绍了DGFI ITRF 2004计算的组合方法和现状。
In its function as an ITRS Combination Center, DGFI has developed refined methods for the terrestrial reference frame computation. The advanced approach is based on the combination of epoch normal equations (weekly/daily data sets) containing Station positions and Earth orientation parameters (EOP) obtained from different geodetic space techniques such as VLBI, SLR, GPS and DORIS. This refined approach allows to account for nonlinear effects (e.g., periodic signals and discontinuities) in Station positions and to ensure consistency between TRF and EOP. The ITRF2004 submissions were used as input for a refined realization of the terrestrial reference frame. This paper presents the combination methodology and the current Status of the ITRF2004 computations at DGFI.
