The two-axis actuation system for the geostationary electro-optical payload is applied to succeed the existing mission and enhance observation performance. In this study, structural analysis was conducted to verify the structural safety of the two-axis actuation system under design loads, launch shock environments, and orbital conditions. First, a modal analysis was performed to predict the dynamic response characteristics of the drive system during launch. Additionally, a quasi-static analysis was conducted to evaluate the structural safety of...

Walker-Delta Constellation Orbit Design Considering Korea Space Launch Vehicle-II (KSLV-II) Performance
누리호 성능을 고려한 Walker-Delta 군집위성 궤도설계

https://doi.org/10.52912/jsta.2025.5.2.73

Korea Space Launch Vehicle-II (KSLV-II) shows the highest efficiency at an input angle of 80 degrees. The launch azimuth angle is fixed at about 172 degrees due to the geographical location and safety range issues of the launch site. The inclination angle of 45 degrees mentioned in recent domestic satellite constellation studies is required yaw maneuvers, which inevitably causes loss in performance. In this study, the satellite constellation are designed based on the 80 degrees inclination, maximizing the injection performance of the payload of...

Counterspace capability known as a part of the military operations involves both offensive and defensive operations within space. It plays an essential role in keeping activities and assets safe in space while also becoming an increasingly important part of national security and military strategies. The aim of this paper is to explore the definition and overall concept of counterspace capability and seek ways for our military to improve its counterspace capability by analyzing empirical examples and weapon systems developed by major nations for...

Genetic Algorithm-Based Proportional, Integral, Derivative (PID) Gain Optimization in an Offset-Compensated Optical Tracking System
유전 알고리즘 기반 옵셋 보정 광학 추적 시스템의 PID(Proportional, Integral, Derivative) 이득 최적화

J. Space Technol. Appl. 2025;5(2):102-113.
https://doi.org/10.52912/jsta.2025.5.2.102

This paper presents a genetic algorithm (GA)-based optimization method for tuning proportional, integral, derivative (PID) gains in an offset-compensated optical tracking system. The system is designed for high-resolution optical identification of unknown space objects and employs initial orbit determination (IOD) to estimate the target trajectory. The controller continuously compensates for image-based center offsets in real time. While prior studies used manually tuned PID gains, this work applies GA to automatically search for gain combinati...

Development of 3D Cell Model for Collision Risk Assessment of Space Assets

With the recent surge in the number of objects in orbit, the collision risk to space assets has grown rapidly. Accurately assessing this risk to support safe operations has therefore become increasingly important. We develop a 3D cell model—a space environment modeling technique for collision assessment—and validate it by comparing our spatial density calculations in low Earth orbit and collision risk results for KITSAT against those produced by MASTER, the 3D grid-cell model developed by European Space Agency (ESA).
