Application of Time Transfer Functions to Gaia's global astrometry - Validation on DPAC simulated Gaia-like observations
Stefano Bertone, Alberto Vecchiato, Beatrice Bucciarelli +5
A key objective of the ESA Gaia satellite is the realization of a quasi-inertial reference frame at visual wavelengths by means of global astrometric techniques. This requires an a…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
The Short Term Stability of a Simulated Differential Astrometric Reference Frame in the Gaia era
U. Abbas, B. Bucciarelli, M. G. Lattanzi +5
We use methods of differential astrometry to construct a small field inertial reference frame stable at the micro-arcsecond level. Such a high level of astrometric precision can be…
