A practical guide to implementing zero-order-hold interplanetary trajectory legs
Dario Izzo, Harry Holt, Giacomo Acciarini +2
We study the practical implementation of zero-order-hold (ZOH) transcriptions for spacecraft trajectory optimisation, identifying a set of design principles that render them robust…
Asteroid Mining: ACT&Friends' Results for the GTOC 12 Problem
Dario Izzo, Marcus Märtens, Laurent Beauregard +8
In 2023, the 12th edition of Global Trajectory Competition was organised around the problem referred to as "Sustainable Asteroid Mining". This paper reports the developments that l…
Computing low-thrust transfers in the asteroid belt, a comparison between astrodynamical manipulations and a machine learning approach
Giacomo Acciarini, Laurent Beauregard, Dario Izzo
Low-thrust trajectories play a crucial role in optimizing scientific output and cost efficiency in asteroid belt missions. Unlike high-thrust transfers, low-thrust trajectories req…
Breaking traditions: introducing a surrogate Primer Vector in non Keplerian dynamics
Laurent Beauregard, Dario Izzo, Giacomo Acciarini
In this study, we investigate trajectories involving multiple impulses within the framework of a generic spacecraft dynamics. Revisiting the age-old query of "How many impulses?",…
