Orbital Dynamics

A simple app put together to simulate certain properties of orbital dynamics and attitude control for a satellite in orbit around the Earth.Currently allows the following controls: - add any number of satellites in various orbits from LEO to beyond GEO - set satellites principle moments of inertia - set 3 axis rotational rates and see cross coupling effects (integration starts when you release the button) - fire main engine along or against orbit to raise or lower semi major axisFuture work would be nice: - have engine work in any arbitrary direction to allow change of eccentricity and inclination - add other (genuine) satellite types - put satellites in eclipse behind earthThis was written to try out some of the maths covered in a university course I was taking, and isn't meant to be more than a bit of general interest. Really optimised for a display of 960x540. Only been tested on a very limited selection of devices ...
