Advancement and analysis of Gauss pseudospectral transcription for optimal control problems
… These optimal control problems involve multiple finite-burn maneuvers, nonlinear dynamics, and nonlinear inequality path constraints that depend on both the relative and inertial positions of all four spacecraft. Contributions of this thesis include an improved numerical method for solving …

Robust preliminary design for multiple gravity assist spacecraft trajectories
… flight-fidelity design tool that models fi nite-burn arcs. Low-thrust trajectories in particular suffer from this issue due to the extended period of time that the thruster operates. Analytic partial derivative computations are introduced in this work that enable the replacement of …
