IGS Comparisons

Comparisons with IGS EOP Series

On the following pages, you will find a comparison between the individual solutions of the Analysis Centers and the IVS combination with respect to the IGS EOP series. The IGS provides final weekly accumulated Earth Rotation Parameters (ERP):

  • X-Pole
  • Y-Pole
  • X-Pole Rate
  • Y-Pole Rate
  • LOD

with respect to the ITRF2005.

The values are estimated from the IGS weekly SINEX combinations.

The comparison is embedded in an interactive tool containing data since 1983. The values are smoothed by a moving median. The subset size of the sliding window is ±35 days and is shifted forward each 7 days. The user is free to display the graphics of the individual solution and to choose the time-spans.

The statistics table is updated according to the chosen data set(s).
