Venusian Radio Occultation Constellation Design and Reconfiguration Problems: A Benders Decomposition Approach
David O. Williams Rogers, Trupti P. Gosavi, Hang Woon Lee
Driven by the scientific value of Venusian atmospheric studies, numerous missions, such as Magellan and Venus Express, have relied on single-spacecraft radio occultation (RO) exper…
Automating the Wildfire Detection and Scheduling Pipeline with Maneuverable Earth Observation Satellites
Brycen D. Pearl, Joshua G. Warner, Hang Woon Lee
Wildfires are becoming increasingly frequent, with potentially devastating consequences, including loss of life, infrastructure destruction, and severe environmental damage. Low-Ea…
Enhancing Orbital Debris Remediation with Reconfigurable Space-Based Laser Constellations
David O. Williams Rogers, Hang Woon Lee
Orbital debris poses an escalating threat to space missions and the long-term sustainability of Earth's orbital environment. The literature proposes various approaches for orbital…
Space Logistics Analysis and Incentive Design for Commercialization of Orbital Debris Remediation
Asaad Abdul-Hamid, Brycen D. Pearl, Hang Woon Lee +1
As orbital debris continues to become a higher priority for the space industry, there is a need to explore how partnerships between the public and private space sector may aid in a…
Reconfigurable Earth Observation Satellite Scheduling Problem
Brycen D. Pearl, Joseph M. Miller, Hang Woon Lee
Earth observation satellites (EOSs) play a pivotal role in capturing and analyzing planetary phenomena, ranging from natural disasters to societal development. The EOS scheduling p…
Optimal Satellite Constellation Configuration Design: A Collection of Mixed Integer Linear Programs
David O. Williams Rogers, Dongshik Won, Dongwook Koh +2
Designing satellite constellation systems involves complex multidisciplinary optimization in which coverage serves as a primary driver of overall system cost and performance. Among…
Deterministic Multistage Constellation Reconfiguration Using Integer Programming and Sequential Decision-Making Methods
Hang Woon Lee, David O. Williams Rogers, Brycen D. Pearl +2
In this paper, we address the problem of reconfiguring Earth observation satellite constellation systems through multiple stages. The Multi-stage Constellation Reconfiguration Prob…
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…
Regional Constellation Reconfiguration Problem: Integer Linear Programming Formulation and Lagrangian Heuristic Method
Hang Woon Lee, Koki Ho
A group of satellites, with either homogeneous or heterogeneous orbital characteristics and/or hardware specifications, can undertake a reconfiguration process due to variations in…
