Abstract:
This talk briefly presents OrbitalTrajectories.jl, a library providing tools for the analysis of orbital trajectories for space mission design. Making use of the Julia scientific modeling ecosystem to easily define and extend high-fidelity simulations of spacecraft motion, we demonstrate how key techniques including meta-programming, symbolic computation, non-linear optimisation, and automatic differentiation work towards generating, analysing, and stabilising orbital trajectories.
