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…
A Semi-analytic Method for Rapid Coverage Analysis of a Satellite Using Piecewise Ellipse Models
Byeong-Un Jo, Jinsung Lee
Satellite coverage analysis commonly relies on intensive numerical computations to evaluate access and revisit times, resulting in high computational costs, particularly in long-te…
Long-Term Earth Magnetosphere Science Orbit via Earth-Moon Resonance Orbit
Jinsung Lee, Jaeyoung Kwak, Jaemyung Ahn
This article investigates long-term orbits within the Earth's magnetosphere, specifically focusing on orbits where the argument of periapsis is synchronized with changes induced by…
Visibility Analysis of the Sun as Viewed from Multiple Spacecraft at the Sun-Earth Lagrange Points
Jinsung Lee, Sung-Hong Park, Arik Posner +2
Beyond the Sun-Earth line, spacecraft equipped with various solar telescopes are intended to be deployed at several different vantage points in the heliosphere to carry out coordin…
