Session theme: System


All space geodesy techniques are now organized separately under the umbrella of the Global Geodetic Observing System. An International DORIS Service was created in 2003 to organize a DORIS contribution to this project of the International Association of Geodesy and to foster a larger international cooperation on this topic. The goal of this paper is to summarize the key steps that were taken to create this structure and to present its current organization and recent results. At present, more than 50 groups from 35 different countries participate in the IDS at various levels, including 43 groups hosting DORIS stations in 32 countries all around the globe. Four analysis groups provide results, such as weekly or monthly station coordinates, geocenter variations or Earth polar motion, that will be used soon to generate IDS combined products for geodesy or geodynamics. Finally, foreseen improvements of the DORIS technology are discussed as well as future improvements concerning the service organization itself and the accuracy and reliability of its scientific products.
