Korean Space Collision Environment Assessment Framework Based on 3D-Cell Model
Jaewoo Kim, Minchan Song, Jinsung Lee +6
Space situational awareness (SSA) requires purpose-matched models across spatial, temporal, and fidelity scales. Building on our previously reported three-dimensional (3D) cell for…
Multi-Domain Matrix Framework for Human Resource Decision Support
Daehan Lee, Jaewoo Kim, Jaemyung Ahn
This paper presents an actionable human resource (HR) decision-support framework for small firms and startups based on a multi-domain matrix (MDM). The framework addresses three ke…
Families of Two-Impulse Optimal Rendezvous Transfers Between Elliptic Orbits
Beom Park, Kathleen C. Howell, Jaewoo Kim +1
The classical fuel-optimal two-impulse rendezvous problem between Keplerian orbits is revisited from a family-based perspective. Conventional approaches often yield isolated optima…
On-Orbit Servicing-Integrated Maintenance Strategy for Satellite Constellation
Jaewoo Kim, Taehyun Sung, Woonam Hwang +1
This paper proposes a maintenance strategy for a satellite constellation that utilizes on-orbit servicing (OOS). Under this strategy, the constellation operator addresses satellite…
System Architecting for GEO Communication Satellite Considering On-Orbit Refueling
Jaewoo Kim, Jaemyung Ahn
This paper introduces the problem of selecting a satellite system architecture considering commercial on-orbit refueling (OOR). This problem answers two questions: "What design lif…
Joint Replenishment Strategy for Multiple Satellite Constellations with Shared Launch Opportunities
Jaewoo Kim, Taehyun Sung, Woonam Hwang +1
This paper proposes a novel replenishment strategy that can jointly support multiple satellite constellations. In this approach, multiple constellations share launch opportunities…
