Real-time spacecraft simulator with animated graphics

We have built a spacecraft simulator which displays realistic graphics in real-time on an inexpensive personal computer (PC). The dynamics of the spacecraft, the positions of the sun, the moon and the earth, and the direction of stars are calculated accurately. The primary use of the simulator would be in the education of statistical signal processing. A student can try a new algorithm for each of the existing modules of the spacecraft by writing a C-code and integrating it with the rest of the simulator.
