The Gaia mission

T. Prusti, +624 more
TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.
Journal ArticleDOI

The astrometric core solution for the Gaia mission. Overview of models, algorithms, and software implementation

TL;DR: The AGIS (Astrometric global iterative solution) as discussed by the authors is a global solution for estimating the position, parallax, and proper motion of a single point-like source.
Journal ArticleDOI

The astrometric core solution for the Gaia mission. Overview of models, algorithms and software implementation

TL;DR: A comprehensive overview of the mathematical and physical models applicable to the astrometric core solution of the Gaia satellite, using a global solution approach, as well as its numerical and algorithmic framework is provided.
