  In this communication, the current tests of gravitation available at Solar
System scales are recalled. These tests rely mainly on two frameworks: the PPN
framework and the search for a fifth force. Some motivations are given to look
for deviations from General Relativity in other frameworks than the two
extensively considered. A recent analysis of Cassini data in a MOND framework
is presented. Furthermore, possibilities to constrain Standard Model Extension
parameters using Solar System data are developed.
