Orbital Dynamics for Android APK

Description

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 ...
