N2 - In this communication, we focus on the possibility to test GR with
radioscience experiments. We present a new software that in a first step
simulates the Range/Doppler signals directly from the space time metric
(thus in GR and in alternative theories of gravity). In a second step, a
least-squares fit of the involved parameters is performed in GR. 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 and with the MOND External
Field Effect.
