Presentation

Since 2007, CNES/GS and CLS teams have been processing regularly GPS data from a worldwide network of IGS permanent stations.
We compute precise GPS orbits together with Earth rotation parameters and stations coordinates at the sub centimetre level.
Our solutions have been submitted since January 2004 to the International Earth Rotation Service in the framework of the Combination Research Center experiment.
