A conjugate gradient algorithm for the astrometric core solution of Gaia
Alex Bombrun, Lennart Lindegren, David Hobbs +3
The ESA space astrometry mission Gaia, planned to be launched in 2013, has been designed to make angular measurements on a global scale with micro-arcsecond accuracy. A key compone…
The astrometric core solution for the Gaia mission. Overview of models, algorithms and software implementation
Lennart Lindegren, Uwe Lammers, David Hobbs +3
The Gaia satellite will observe about one billion stars and other point-like sources. The astrometric core solution will determine the astrometric parameters (position, parallax, a…
Implementing the Gaia Astrometric Global Iterative Solution (AGIS) in Java
William O'Mullane, Uwe Lammers, Lennart Lindegren +2
This paper provides a description of the Java software framework which has been constructed to run the Astrometric Global Iterative Solution for the Gaia mission. This is the mathe…
Using Galactic Cepheids to verify Gaia parallaxes
Fredrik Windmark, Lennart Lindegren, David Hobbs
Context. The Gaia satellite will measure highly accurate absolute parallaxes of hundreds of millions of stars by comparing the parallactic displacements in the two fields of view o…
