Repro3 Solutions Now Available

By IGS Central Bureau and IGS Reference Frame Coordinator

The final daily and weekly combined terrestrial frame solutions from the 3rd IGS reprocessing campaign (repro3), which form the IGS contribution to ITRF2020, are now available, with the prefix “IGS1R03SNX”, at ftp://igs-rf.ign.fr/pub/repro3.

Since the previous preliminary release two months ago, some contributing Analysis Centers (ACs) could extend their reprocessing. The final IGS repro3 terrestrial frame solutions are thus combinations of the following AC contributions:

– GLONASS included starting from 2002-01-01
– Galileo included starting from 2013-01-01

* ESA (European Space Agency):  1995-01-01 to 2020-12-31
– GLONASS included starting from 2009-01-01
– Galileo included starting from 2015-01-01

* GFZ (GeoForschungsZentrum):  1994-01-02 to 2020-12-31
