Presentation

Since 2007, CNES/GS and CLS teams have been processing regularly GNSS data from a worldwide network of IGS permanent stations.
Our products, GNSS orbits and clocks together with Earth rotation parameters and stations coordinates at the sub centimetre level, participate to the International GNSS Service combinaison and are available on IGS products centers.
