A simulation of a space mission on the ground with a satellite that will eventually be in space. Take your satellite, replace it's navigation/communication inputs with ones generated by a reasonably high fidelity real time physical simulation. Feed it's outputs back into said simulation. Ensure the satellite does the right things at the right time.
