Poster

In the framework of the IVS, the Bordeaux Observatory has been an associate analysis center since the very beginning. Currently, the Bordeaux IVS activities can be detailed into three simultaneous parts. (1) The IVS data are regularly analyzed with the GINS software of GRGS/CNES (Groupe de Recherche de Géodésie Spatiale – Centre National d'Etudes Spatiales), for determining EOP (Earth Orientation Parameters) and ITRF (International Terrestrial Reference Frame), in the framework of the space-geodetic techniques combination. (2) Furthermore, the structure of the sources from the ICRF catalogue (International Celestial Reference Frame) is regularly monitored, by determining the corresponding VLBI images (as well as the source correction and visibility maps). (3) Finally, the Bordeaux IVS analysis center is involved in more prospective studies related to VLBI observing programs with the EVN and the VLBA (European VLBI Network; Very Long Baseline Array) and simulations for future VLBI network improvements (e.g. VLBI2010 project). This paper is aimed at presenting the current activities as well as the future plans of the Bordeaux VLBI team.
