Orbit Architect allows you to interactively design and explore satellite orbital geometry through the multi-touch interface of the iPad. You can manipulate a satellite orbit using pinch and rotate multi-touch gestures, see the effects on the orbit and its ground track in real-time, and animate the results. As you change the orbit, dynamic diagrams will illuminate the meaning of each orbital parameter. Finally, the results can then be emailed to yourself or to a friend.

Not bad for a simple freebie!
What I'd REALLY like to see is some simple "thrust" types of controls for prograde/antigrade normal/antinormal orbits so you can see the effect that such a maneuver would have on a body - and to teach orbital maneuvering-type of stuff - but that's getting into a more sophisticated program!
Observing the sat's tracking path across the globe's surface is THE cool feature...fascinating. This feature would be even better if the orbital tracing were increased beyond 3. Perhaps 5? GREAT free app!
