This is the proof of concept for the full simulation system. It shows that simulating a mission accurately is possible, after some more refinement. For the time being I’m moving chronologically to build up the flight system to be more robust, but more at the relative pace SpaceX went. I may add a code walkthrough section to this later, but hopefully this will be replaced by a more advanced system in the future. For now, please view the flights that have been simulated on the main KSP F9 Flight GNC page.
