News on Seeking Gaia's Astrometric Core Solution with AGIS
(2011) In EAS Publications Series 45(GAIA: At the Frontiers of Astrometry). p.123-126- Abstract
- We report on recent new developments around the Astrometric Global Iterative Solution system. This includes the availability of an efficient Conjugate Gradient solver and the Generic Astrometric Calibration scheme that had been proposed a while ago. The number of primary stars to be included in the core solution is now believed to be significantly higher than the 100 Million that served as baseline until now. Cloud computing services are being studied as a possible cost-effective alternative to running AGIS on dedicated computing hardware at ESAC during the operational phase.
