Résumé en anglais

Abstract. The Bordeaux Observatory has been an associate Analysis Center of the Inter- national VLBI Service for geodesy and astrom- etry (IVS) since the very beginning of this ser- vice in 1999. At present, the Bordeaux Obser- vatory IVS activities are focused on three differ- ent areas. The IVS data are regularly analyzed with the GINS software for determining the EOP (Earth Orientation Parameters) and the ITRF (International Terrestrial Reference Frame) in the framework of a pro ject to combine the data of all space-geodetic techniques at the observation level. Additionally, the structure of the sources from the ICRF (International Celestial Reference Frame) is regularly monitored, through VLBI imaging along with the astrometric quality of these sources. Finally, the Bordeaux IVS analy- sis center is involved in more prospective studies comprising VLBI observing programs with the European VLBI Network (EVN) and Very Long Baseline Array (VLBA), and simulations for fu- ture VLBI network improvements (VLBI2010 pro ject). This paper is aimed at presenting the current activities as well as the future plans of the Bordeaux VLBI team< Réduire
