Radioscience simulations in General Relativity and in alternative theories of gravity

Understand

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.
