A general relativistic model for the light propagation in the gravitational field of the Solar System: the dynamical case
Fernando de Felice, Alberto Vecchiato, Maria Teresa Crosta +2
Modern astrometry is based on angular measurements at the micro-arcsecond level. At this accuracy a fully general relativistic treatment of the data reduction is required. This pap…
A General Relativistic Model of Light Propagation in the Gravitational Field of the Solar System: the Static Case
F. de Felice, M. T. Crosta, A. Vecchiato +2
We develop here a new approach for the relativistic modeling of the photons moving into a quasi-Minkowskian space-time, where the metric is generated by an arbitrary n-body distrib…
Some aspects of Relativistic Astrometry from within the Solar System
Maria Teresa Crosta, Alberto Vecchiato, Fernando de Felice +2
In this article we outline the structure of a general relativistic astrometric model which has been developed to deduce the position and proper motion of stars from 1-microarcsecon…
Testing general relativity by micro-arcsecond global astrometry
Alberto Vecchiato, Mario G. Lattanzi, Beatrice Bucciarelli +3
The global astrometric observations of a GAIA-like satellite were modeled within the PPN formulation of Post-Newtonian gravitation. An extensive experimental campaign based on real…
