Testing the gravitational redshift with Galileo satellites
P. Delva, N. Puchades, E. Schönemann +11
We present the results of the analysis of the GREAT (Galileo gravitational Redshift test with Eccentric sATellites) experiment from SYRTE (Observatoire de Paris), funded by the Eur…
A gravitational redshift test using eccentric Galileo satellites
P. Delva, N. Puchades, E. Schönemann +11
We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of gene…
Approaches to relativistic positioning around Earth and error estimations
Neus Puchades, Diego Sáez
In the context of relativistic positioning, the coordinates of a given user may be calculated by using suitable information broadcast by a 4-tuple of satellites. Our 4-tuples belon…
Relativistic Positioning Systems: Numerical Simulations
Neus Puchades, Diego Sáez
The motion of satellite constellations similar to GPS and Galileo is numerically simulated and, then, the region where bifurcation (double positioning) occurs is appropriately repr…
Relativistic positioning: errors due to uncertainties in the satellite world lines
Neus Puchades, Diego Sáez
Global navigation satellite systems use appropriate satellite constellations to get the coordinates of an user -close to Earth- in an almost inertial reference system. We have simu…
Relativistic positioning: four-dimensional numerical approach in Minkowski space-time
Neus Puchades, Diego Sáez
We simulate the satellite constellations of two Global Navigation Satellite Systems: Galileo (EU) and GPS (USA). Satellite motions are described in the Schwarzschild space-time pro…
