Mapping the spacetime metric with GNSS: a preliminary study
P. Delva, J. T. Olympio
In order to do relativistic gravimetry one needs to define a system of null coordinates for a given constellation of satellites. We present here three methods in order to find the…
Extended Fermi coordinates
P. Delva, M. -C. Angonin
We extend the notion of Fermi coordinates to a generalized definition in which the highest orders are described by arbitrary functions. From this definition rises a formalism that…
Vibrating systems in Schwarzschild spacetime: towards new experiments in gravitation?
L. Bergamin, P. Delva, A. Hees
In this paper the effects of vibrations at high frequencies onto a freely falling two-body system in Schwarzschild spacetime are investigated. As reference motion of the same syste…
The relativistic glider revisited
L. Bergamin, P. Delva, A. Hees
In this paper we analyze some aspects of the "relativistic glider" proposed by Guéron and Mosna more in detail. In particular an explicit weak gravity and low velocity expansion is…
