위성의 전력 시스템 초기 설계를 위해 고려해야 하는 중요한 설계 요소에는 위성 운용 기간 동안의 전력 소모량 예측 및 전이궤도와 운용궤도에서의 태양 전지판과 배터리의 운용 개념 설계이다. 이를 토대로 태양 전지판에서 생성되는 전력의 정류 개념과 배터리 충전/방전 토폴로지를 구현해야 한다. 본 논문에서는 2.5KW급 정지궤도 위성의 전력 시스템 초기 설계를 위해 고려해야 하는 설계 요소들을 나열하고, 이들에 대한 전반적인 검토 사항을 기술한다.

성공적 군사작전 지원을 위한 전술항공정찰 임무 수행 능력 구비를 위해서는 각 정보 수집 체계별 보유 기술 수준과 가용예산, 획득 우선 순위 등을 고려하여 현 작전수행 개념에 의거 운용 체제를 구축해야 할 것이다. 특히 전술항공정찰을 통한 영상정보의 수집은 항공작전 수행시 성공적인 임무수행의 보장과 통합 임무명령을 작성하기 위해 기초자료를 제공하는 핵심 활동의 하나이므로 전술항공 정찰 체계도 전투기 확보와 같은 비중과 종합적인 운용개념을 가지고 검토되고 확보되어야 할 것이다

This study explores the application of Mission Engineering, a concept and methodology adopted by the U.S. Department of Defense, to the Republic of Korea's defense planning and management system in response to the rapidly changing security environment. Through literature review, analysis of prior research and case studies, and focus group interviews (FGI), key elements of Mission Engineering were derived. Based on these findings, improvements for the ROK military's requirements planning and rapid acquisition system were proposed. As a result, three critical elements for applying Mission Engineering were identified: operational concepts, required capabilities, and acquisition. Suggestions for improvement include transitioning to a mission-oriented requirements planning system, applying Mission Engineering methodology when formulating operational concepts, supporting decision-making to shorten acquisition timelines, allocating budgets for rapid acquisition, and strengthening the capabilities of requirement-setting units. This study confirms the necessity and applicability of Mission Engineering and is expected to serve as a foundation for the future development of the defense planning and management system.

우주발사체 추적용 지상국비행종단지령장비는 위성발사체 발사 후 비행 중 일어날 수 있는 비상사태(비행안전영역을 벗어나거나 지상에서 더 이상 추적이 불가능할 경우)에 대하여 지상통제장치에서 비행종단을 명령하여 비행을 강제로 종단시키는 역할을 한다. 일반적으로 발사체에 비행종단을 명령하는 방식은 발사체의 종류 및 운용개념에 따라 다르게 적용되며, 가청주파수 대역의 톤 신호를 조합하는 IRIG 표준 톤 방식과 Secure 방식, 또한 잡음 및 보안특성에 강한 암호화 코드화 방식이 사용되고 있다. 본 글에서는 비행종단명령에 사용되는 다양한 전송방식 및 적용 사례를 살펴보고 세계 각국 및 국내 나로우주센터(고흥)에서 설치 운용 중인 지상국비행종단지령장비에 대한 운용개념 및 주요특성을 살펴보도록 한다.

With the advent of industry 4.0 technologies like the artificial intelligence and the autonomous flight, 'Urban Air Mobility (UAM)' is being considered as an effective alternative to resolve the ground urban traffic congestion. Accordingly, many companies in the world including Korea are investigating on the development of UAM vehicles and operation systems. In this study, after identifying and classifying the essential elements of the UAM operation, the UAM system operational concept has been derived, then detailed analyses for each element has been performed. Based on the conceptual analysis of the UAM operation system, UAM flight routes in Seoul and Gyeong-In area have been established and confirmed to be operable through the performance analysis of UAM vehicles. The flight route analysis in this study is expected to be applied to UAM flight routes establishment in various cities in the future.

UAV-UGV teaming concept has been proposed that can compensate for weak points of each platform by providing carrying, launching, recovery and recharging capability for the VTOL-UAV through the host UGV. The teaming concept can expand the observation envelop of the UGV and extend the operational capability of the UAV through mechanical combination of each system. The spherical-shaped coaxial rotorcraft UAV is suggested to provide flexible and precise interface between two systems. Hybrid navigation solution that included vision-based target tracking method for precision landing is investigated and its experimental study is performed. Feasibility study on length-variable rotor to provide the compact configuration of the loaded rotorcraft platform is also described.
