Hobbs, David LU ; Lindegren, Lennart LU ; Holl, Berry LU ; Lammers, Uwe and O'Mullane, William (2008) IAU Symposium 248 In Proceedings of IInternational Astronomical Union, IAU Symposium 248. p.119-120
Abstract
Gaia is an ESA space astrometry mission due for launch in 2011-12. We describe part of the work carried out in the Gaia Data Processing and Analysis Consortium, namely

the Astrometric Global Iterative Solution (AGIS) currently being implemented at the European Space Astronomy Center (ESAC) in Spain and largely based on algorithms developed at Lund Observatory. Some provisional results based on simulated observations of one million stars are

presented, demonstrating convergence at microarcsec level independent of starting conditions.
