The GRGS (French Space Geodesy Research Group) AC is operated jointly by CNES and CLS in Toulouse. Their website at http://igsac-cnes.cls.fr/ gives full details of the AC, their processing strategy, and other information. It should be mentioned that GRGS uses a unique method to fix phase ambiguities for undifferenced observations. Entry of GRGS into the IGS products follows a period of extensive evaluation. We are honored to welcome this group into our company! Please also note that the GFZ/Potsdam (German Research Centre for Geosciences) AC augmented their IGS Final contributions to add GLONASS satellites starting week 1579. We are thankful for this very valuable step by GFZ to improve the robustness of the IGLOS orbits.
