Hierarchical Framework for Space Exploration Campaign Schedule Optimization
Nicholas Gollins, Koki Ho
Space exploration plans are becoming increasingly complex as public agencies and private companies target deep-space locations, such as cislunar space and beyond, which require lon…
Analysis of Cooperative and Non-Cooperative Architectures for Multi-Plane On-Orbit Refueling
Kosuke Ikeya, Koki Ho
As many satellite constellations are proposed, deployed, and operated, their maintenance becomes increasingly important to provide satisfactory services; therefore, on-orbit refuel…
Optimizing Multi-Spacecraft Cislunar Space Domain Awareness Systems via Hidden-Genes Genetic Algorithm
Lois Visonneau, Yuri Shimane, Koki Ho
This paper proposes an optimization problem formulation to tackle the challenges of cislunar Space Domain Awareness (SDA) through multi-spacecraft monitoring. Due to the large volu…
Simultaneous Sizing of a Rocket Family with Embedded Trajectory Optimization
Byeong-Un Jo, Koki Ho
This paper presents a sizing procedure for a rocket family capable of fulfilling multiple missions, considering the commonalities between the vehicles. The procedure aims to take f…
Orbital Facility Location Problem for Satellite Constellation Servicing Depots
Yuri Shimane, Nick Gollins, Koki Ho
This work proposes an adaptation of the Facility Location Problem for the optimal placement of on-orbit servicing depots for satellite constellations in high-altitude orbit. The hi…
