Analytical Confidence Boundaries for Non-Gaussian Uncertainty in Perturbed Spacecraft Dynamics

Niccolò Michelotti, Ethan R. Burnett, Francesco Topputo

This work investigates nonlinear uncertainty propagation in perturbed astrodynamics, focusing on the rapid characterization of non-Gaussian distributions and the construction of three-dimensional "banana-shaped" confidence boundaries. To bridge the gap between computationally int…

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 the cislunar environment or deep space flybys, the dynamics can be particularly nonlinear, and time b…
