Abstract
In this thesis, a solution to the Global Trajectory Optimization Competition (GTOC) 11 problem statement is developed and compared to a solution submitted to the competition by the Iowa State University (ISU) GTOC team. The solution presented in this report involves an optimization of impulsive thrust trajectories, distribution of asteroids to Dyson Ring build stations and continuous low-thrust trajectories. The solution presented in this report focuses on a different method of determining the impulsive thrust trajectories compared to the submitted solution from the ISU GTOC team and the solutions of those who presented their solutions at a workshop held by GTOC. The generated solution resulted in an improved number of asteroids chosen and a decrease of average impulsive thrust during the impulsive thrust component. This solution also showed an improved number of asteroids distributed to the build stations with a higher minimum build station mass, when compared to the solution submitted by the ISU GTOC team.
