Orbital Rocket Guidance with Ruby
summary
Uses Kerbal Space Program plus the kRPC gem and Ruby to emulate an Apollo Guidance Computer style controller, building a cooperative multitasker with seven-word corsets and a seven-entry wait list. Implements restart protection, a “night watchman” watchdog, gravity-turn open-loop then iterative closed-loop guidance, staging and ullage sequencing, and reproduces a Saturn V ascent to orbital velocity (~17,000 MPH) in simulation — the Ruby controller runs and achieves orbit in the demo.
