Simulations of Solar System observations in alternative theories of gravity

Understand

In this communication, we focus on the possibility to test General Relativity (GR) with radioscience experiments.

• We present simulations of observables performed in alternative theories of gravity using a software that simulates Range/Doppler signals directly from the space time metric.
• This software allows one to get the order of magnitude and the signature of the modifications induced by an alternative theory of gravity on radioscience signals.
• As examples, we present some simulations for the Cassini mission in Post-Einsteinian gravity (PEG) and with Standard Model Extension (SME).
