During the time span of more than a decade since the official start of the IGS (International GNSS Service) in 1994, considerable improvements in the processing strategies and modeling of global GPS solutions were achieved.
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. If you decide to use the GPS-PDR reprocessing products, please refer to the publication by Steigenberger et al. (2006) given below in any publication or presentation.
All data files alternatively are available with the ISDC standard or the Bernese data file names. By default requests are limited to 1000 files or 1 GB within 24 hours. You can request a higher file-limit and more space via Edit your personal information.
