Formulation and Analysis for Integrated Spacecraft Routing and Trajectory Design Problem
Euihyeon Choi, Koki Ho
This paper studies the integrated spacecraft routing and trajectory optimization problem for satellite servicing missions involving partial en-route propellant replenishment. Unlik…
Revolution-Spaced Output-Feedback Model Predictive Control for Station Keeping on Near-Rectilinear Halo Orbits
Yuri Shimane, Stefano Di Cairano, Koki Ho +1
We develop a model predictive control (MPC) policy for station keeping on a Near-Rectilinear Halo Orbit (NRHO). The proposed policy achieves full-state tracking of a reference NRHO…
Cislunar Space Situational Awareness Constellation Design and Planning with Facility Location Problem
Yuri Shimane, Kento Tomita, Koki Ho
Driven by the surmounting interest for dedicated infrastructure in cislunar space, this work considers the satellite constellation design for cislunar space situational awareness (…
Cislunar Satellite Constellation Design Via Integer Linear Programming
Malav Patel, Yuri Shimane, Hang Woon Lee +1
Cislunar space domain awareness is of increasing interest to the international community as Earth-Moon traffic is projected to increase, which raises the problem of placing space-b…
Real-Time Stochastic Terrain Mapping and Processing for Autonomous Safe Landing
Kento Tomita, Koki Ho
Onboard terrain sensing and mapping for safe planetary landings often suffer from missed hazardous features, e.g., small rocks, due to the large observational range and the limited…
Concurrent Optimization of Satellite Phasing and Tasking for Cislunar Space Situational Awareness
Malav Patel, Kento Tomita, Koki Ho
Recently, renewed interest in cislunar space spurred by private and public organizations has driven research for future infrastructure in the region. As Earth-Moon traffic increase…
