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 axis
Future 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 earth
This 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 ...
