Real-time animation software for displaying sensor images and actuator operations in a spacecraft

We have built a spacecraft simulator which displays realistic graphics in real-time on inexpensive personal computers. 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 and control. We have tested the simulator in graduate EE classes (Stanford University, and KAIST) with a great success.
