On April 8 -10, 2015, 22 members of the Gaia Data Processing and Analysis Consortium DPAC met at the Center for Astronomy of the University of Heidelberg in order to discuss the current status of AGIS. AGIS is the Astrometric Global Iterative Solution, a mathematical procedure that will determine the positions, movements, and distances of about one billion stars from the individual measurements of the Gaia satellite.
Klaus Jäger and Stefan Jordan have produced a 15 minute DPAC outreach video which explains the Gaia mission and its goals. The movie contains interviews with Lennart Lindegren, the intellectual father of AGIS, with Uwe Lammers, the Gaia Science Operations Manager, and with Ulrich Bastian, the scientific manager of the Gaia core processing. These three scientists explain what AGIS is and what its challenges are. They describe the progress of the AGIS development which will finally result in the most accurate star catalogue ever.
