Abstract

Gaia, the space astrometry satellite of the European Space Agency, was successfully launched on 2013 December 19th. A vast amount of data has already been received by the on-ground data processing systems running at the European Space Astronomy Centre near Madrid. In this paper we describe the mentioned systems, focusing on the Initial Data Treatment system which is coordinated by the Gaia group at the University of Barcelona. We present some of the results obtained during the first months of nominal operations.
