Time transfer functions as a way to validate light propagation solutions for space astrometry
Stefano Bertone,Stefano Bertone,Olivier Minazzoli,Mariateresa Crosta,Christophe Le Poncin-Lafitte,Alberto Vecchiato,Marie-Christine Angonin +6 more
TL;DR: In this paper, the time of flight and tangent vectors in a closed form within the TTF formalism were compared with two existing modelings, namely the Gaia RElativistic Model (GREM) and the Relativistic Astrometric MODel (RAMOD).

Time Transfer functions as a way to validate light propagation solutions for space astrometry
Stefano Bertone,Stefano Bertone,Olivier Minazzoli,Mariateresa Crosta,Christophe Le Poncin-Lafitte,Alberto Vecchiato,Marie-Christine Angonin +6 more
TL;DR: In this paper, the authors show how to use this new approach to obtain a comparison of the TTF with two existing modelings, namely GREM and RAMOD, and evidentiate the mutual consistency of the three models, opening the basis for further links between all the approaches.

Gravitation Astrometric Measurement Experiment
TL;DR: The Gravitation Astrometric Measurement Experiment (GAME) is a mission concept based on astronomical techniques (astrometry and coronagraphy) for fundamental physics measurements, namely the \gamma\ and \beta\ parameters of the Parametrized Post-Newtonian formulation of gravitation theories extending the General Relativity.

The Erez-Rosen metric and the role of the quadrupole on light propagation
TL;DR: In this paper, the role of the quadrupole in the motion, deflection and lensing of a light ray in the spacetime metric is investigated, and the corresponding analytical solution of the inverse ray tracing problem as well as the consistency with other approaches are also discussed.
