Simulate all electro-mechanical and digiital equipment for the NASA STEREO Experiment so that it will run millions of lines of NASA written software for the purpose of software requirements testing and verification.

The NASA STEREO Experiment consists of two identical sattelites in orbit around the sun that act like binoculars.. There is a complete Newtonian model that uses thrustors and reaction wheels to control movement.  It's orbit around the sun is simulated and its postition in space is calculated by the Star Tracker and other information.
