Spacecraft trajectory design utilizing resonance orbits in a hybrid optimal control framework

DT Bunce - 2017 - ideals.illinois.edu
Low-energy trajectories are a growing subset of trajectory design, particularly in the three-
body space. These trajectories use the inherent stability and instability of certain orbits as a …

Automated detection of invariant manifold intersections using grid based approach

JD Aurich - 2017 - ideals.illinois.edu
When designing spacecraft trajectories, there exist cases where a trade-off between time-of-
flight and fuel become crucial to the mission design scenario, especially for unmanned …
