Résumé : The European Space Agency mission Gaia, to be launched in 2012, will observe millions of binaries ranging from contact eclipsing ones to wide pairs with hundred year periods. Whether they are identified by astrometric, photometric, or spectroscopic techniques, they will benefit from a thorough and robust processing which aims at supplying the community with (at least) an unbiased estimate of the parallax, proper motion and systemic velocity. Orbital parameters for most of these detected binaries and even individual masses for thousands of them make Gaia a very valuable instrument for the double star community. © 2011 American Institute of Physics.
