An Efficient Non-Gaussian Chance Constraint Method for Stochastic Nonlinear Problems in Spaceflight
Ethan R. Burnett, Spencer Boone, Niccolo Michelotti
Standard chance-constrained spacecraft guidance typically relies on the assumption that uncertainties in vehicle states obey Gaussian statistics. In frontier applications such as t…
Taylor polynomial-based constrained solver for fuel-optimal low-thrust trajectory optimisation
Thomas Caleb, Roberto Armellin, Spencer Boone +1
This paper presents differential algebra-based differential dynamic programming (DADDy), a publicly available C++ framework for constrained, fuel-optimal low-thrust trajectory opti…
Analytic Non-Gaussian Confidence Boundary Method for Chance-Constrained Trajectory Control
Ethan Burnett, Spencer Boone
Standard chance constrained control algorithms typically rely on the assumption that uncertainties in vehicle states obey Gaussian statistics. Highly nonlinear systems tend to disr…
Catalog and Characterization of Science Orbit Configurations for an Enceladus Orbiter
Spencer Boone, Joan Pau Sanchez Cuartialles, Stéphanie Lizy-Destrez
Saturn's moon Enceladus is an exciting destination for future exploration missions due to the scientifically interesting geyser region located on its South pole. In this work, we c…
