Impact analysis of the transponder time delay on radio-tracking observables
Stefano Bertone, Christophe Le Poncin-Lafitte, Pascal Rosenblatt +3
Accurate tracking of probes is one of the key points of space exploration. Range and Doppler techniques are the most commonly used. In this paper we analyze the impact of the trans…
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…
