GPS-PDR ISDC

The data is in the phase of migration to another system. Therefore the repository is no longer available. This record is out-dated.; 2020-10-06 Due to the changes at the individual IGS analysis centers during these years the resulting time series of global geodetic parameters are inhomogeneous and inconsistent. A geophysical interpretation of these long series and the realization of a high-accuracy global reference frame are therefore difficult and questionable. The GPS reprocessing project GPS-PDR (Potsdam Dresden Reprocessing), initiated by TU München and TU Dresden and continued by GFZ Potsdam and TU Dresden, provides selected products of a homogeneously reprocessed global GPS network such as GPS satellite orbits and Earth rotation parameters.

当前数据集正处于向另一系统迁移的阶段，因此原数据仓库已不再可用。该记录已过时。自2020年10月6日起，由于个人国际地球自转服务机构（IGS）分析中心在这些年间发生的变动，全球大地测量参数的时间序列呈现出不均匀和不一致的特征。因此，对这些长期时间序列进行地球物理解释以及实现高精度全球参考框架变得困难和存疑。由慕尼黑工业大学（TU München）和德累斯顿工业大学（TU Dresden）发起，并由波茨坦地球物理研究所（GFZ Potsdam）和德累斯顿工业大学（TU Dresden）继续进行的GPS重处理项目GPS-PDR（Potsdam Dresden Reprocessing），提供了经过均匀重处理的全球GPS网络选区产品，如GPS卫星轨道和地球自转参数。
