AB: LEGOS/GRGS and CLS have been involved in DORIS data processing since the launch of Spot-2 in 1990. They are in charge of the scientific analysis of DORIS data in the field of geodesy, geophysics and space oceanography. They decided to jointly participate as Analysis Center for the International DORIS Service (IDS) which has been officially started on July 1, 2003 as an IAG Service. The goal of this paper is to present the current activities of the Center realized with the GINS/DYNAMO software, as well as the recent evolutions brought to the processing. One of the most important is the contribution of the three new instruments launched during the last two years onboard Jason-1, Spot-5, and Envisat. We will present the contribution of the new satellites to the positioning performances. Recently, the first Grace Gravity Model has been released. We will present results obtained with this new gravity model.
