A collection of code for low-fidelity interplanetary navigation and guidance modeling and simulation. It was developed for the ENAE741 at the University of Maryland. It's not exactly in a complete state, so I'm leaving it unregistered for now.
Most functions should be at least minimally documented; some familiarity with the concepts of interplanetary astrodynamics will be helpful.
Examples are in the examples/ directory. They can be run inside the directory with include("<example name>.jl").
