SaToR-G (Satellite Tests of Relativistic Gravity) is a fundamental physics experiment of the National Scientific Committee 2 (CSN2) of the Italian National Institute for Nuclear Physics (INFN). SaToR-G aims at testing gravitation beyond the predictions of General Relativity (GR) in its weak-field and slow-motion limit, searching for effects foreseen by alternative theories of gravitation and possibly connected with ‘’new physics’’. The predictions of General Relativity on the orbits of laser-tracked satellites such as the two LAGEOS and LARES -- which play the role of proof masses -- will be compared with those of other metric and non-metric theories of gravity. The analysis of the orbital residuals of the satellites will be presented with the activities related to the development of perturbative models to better determine their orbital dynamics together with new preliminary constraints to some alternative theories of gravitation.
