ABSTRACT We consider the feasibility of using the Galileo Navigation Satellite System
to constrain possible extensions or modifications to General Relativity, by
assessing the impact of the related additions to the Newtonian potential and
comparing with the available observables: the relative frequency shift and the
time delay of light propagation. We address the impact of deviations from
General Relativity based on the parameterized Post-Newtonian parameters due to
the presence of a Cosmological Constant, of a constant acceleration like the
putative Pioneer anomaly, a Yukawa potential term due to massive scalar fields
and a power-law potential term, which can arise from Ungravity or f(R)
theories.

    ABSTRACT: We consider unparticle inspired corrections of the type ${(\frac{R_{G}}{r})}^\beta$ to the Newtonian potential in the context of the gravitational quantum well. The new energy spectrum is computed and bounds on the parameters of these corrections are obtained from the knowledge of the energy eigenvalues of the gravitational quantum well as measured by the GRANIT experiment.

    ABSTRACT: In the last few years, the so-called flyby anomaly has been widely discussed, but remains still an illusive topic. This is due to the harsh conditions experienced during an Earth flyby as well as due to the limited data available. In this work, we assess the possibility of confirming and characterizing this anomaly by resorting to the scientific capabilities of the future Galileo constellation.

    ABSTRACT: We propose the concept of a space mission to probe the so called flyby anomaly, an unexpected velocity change experienced by some deep-space probes using earth gravity assists. The key feature of this proposal is the use of GNSS systems to obtain an increased accuracy in the tracking of the approaching spacecraft, mainly near the perigee. Two low-cost options are also discussed to further test this anomaly: an add-on to an existing spacecraft and a dedicated mission.
