차세대 항공전자 시스템은 표준화 모듈의 데이터통신에 기반한 개방형 아키텍처와 범용성을 위한 새로운 시스템 개발이 요구된다. 본 논문에서는 차세대 항공전자 비행운영 프로그램을 지원하기 위한 메시지 기반 미들웨어를 설계하고 이에 대한 구현 및 테스트를 통한 적용성을 검증한다. 시스템 구성은 임무컴퓨터 (Mission Computer, MC)와 대화면 시현기 (Large Area Display, LAD)를 포함하며 고신뢰의 이더넷기반의 소켓통신이 사용하였다. 마지막으로 실험결과 제안된 방법은 모든 패킷이 20msec의 데드라인에 패킷 손실이 전혀 없이 전달됨으로써 실시간성과 신뢰성 요구사항을 만족시키는 것으로 판명되었다.

The article substantiates the need and shows the features of introducing SMART management into the system of public management of regional development in the context of strengthening the national security of Ukraine. Disclosed are such provisions as: goal-setting; state mission; state mission in Ukraine; goals of the Ukrainian state; strategic management priorities in Ukraine. Differences between the purpose of the organization and the purpose of the state are determined. The characteristic of the goal at the state level is given. The management standards in SMART management are characterized. The issues of the exhaustibility of existing SMART criteria are reviewed and it is proposed to supplement them with two such as: inspiration (inspiration) and ity (ethics). Two main principles are defined (evaluated (assessment), reviewed (review)), which must be observed when introducing SMART management into the system of public management of regional development in the context of strengthening the national security of Ukraine.

사이버 공격은 조직과 국가에 큰 피해를 주려는 목적으로 정보를 가로채고 파괴하는 의도적인 행동으로 빚어지는 경우가 많다. 이에 따라 국제 표준화 기구(ISO)는 ISO/IEC 27000 시리즈 등 정보 자산의 보호를 위한 표준 문서를 지침으로 제공한다. 하지만 지침만 제공할 뿐 자산 보호를 위한 구체적인 방법이나 절차가 포함되어 있지 않다. 본 연구에서는 공군의 긴급 CAS(Close Air Support) 작전을 대상으로 추후 사이버 전투 피해평가를 위해 사이버 공격에 의한 정보 자산에 대한 점수를 가산화 한다. 긴급 CAS 작전 시뮬레이션 진행 후 도출된 요소를 가지고 객관적인 수치라고 할 수 있는 CIA(Confidentiality, Integrity, Availability)지표들과 군 정보를 접목시켜 자산의 중요성을 계산하고 나아가 가중치를 주어 차별성을 가지게 된다.

Analytical formulae are presented to approximate the evolution of the semi major axis, the maneuver time, and the final mass fraction for low thrust orbital transfers with circular initial orbit, circular target orbit, and constant thrust directed either always along or always opposite the velocity vector. For comparison, the associated results for high-thrust transfers, i.e. the two-impulse Hohmann transfer, are summarized. All results are implemented in a computer code designed to analyze planar planetary and interplanetary space missions. This implementation yields fast and reasonably accurate approximations to trajectory performance boundaries. Consequently, the approach can provide trajectory analysis for each spacecraft configuration during the conceptual space mission design phase. As an example, a mission from Low-Earth Orbit (LEO) to Jupiter's moon Europa is analyzed.

MSC is being developed to be installed on KOMPSAT(Korea Multi-Purpose Satellite-II and to provide high resolution multi-spectral. MSC consists of three main subsystems. One is EOS(Electro-Optics Subsystem), another is PMU(Payload Management Unit) and the other is PDTS(Payload Data Transmission Subsystem). There is an SBC(Single Board Computer) in the PMU to control all MSC subsystems. SBC incorporates Intel 80486 as a main processor and VxWorks as a real-time operating system. SBC software consists of four main tasks and several modules to deal with all control information for imaging and all the state of health telemetrv data, and to perform interface with another MSC units. SBC software also has to handle a lot of commands in order for MSC to perform his mission. One mission command consists of a series of related commands, which are In be executed in the designated sequence, with a specified time ...

Autonomous Underwater Vehicles(AUVs) have become an important tool for various purposes in subsea: inspection, recovery, construction, etc., and the development of autonomous control system is luglay desirable- thete zffe many problems associated with designing the control system for AUV due to unknown underwater envimn-Tnent, the possibility of subsystem failures, and unpredictable changes in the dynamics of the vehicle. In this paper, an autonomous control system based on the intelligent control theory to enhance operation efficiency of the ALTV is presented. The control system has a hierarchical structure which consists of mission planning level, mission control level, navigation level, and execution level. The performance of the control system is investigated by computer simulation. The results show that the proposed control system can be applied successfully to the AUV in spite of the possibility of failures in the vehicle and the collision hazard in the sea environment.

This paper describes the system for detecting the tank crew's(loader's) hand, arm, head and the upper half of the body in a danger area between the turret ceiling and the upper breech mechanism by computer vision-based method. This system informs danger of pressed to death to gunner and commander for the safety of operating mission. The camera mounted ort the top portion of the turret ceiling. The system sets search moving object from this image and detects by using change of image, laplacian operator and clustering algorithm in this area. It alarms the tank crews when it's judged that dangerous situation for operating mission. The result In this experiment shows that the detection rate maintains in $81{\sim}98$ percents.

With the development of the industry, the use of drones in specific mission flight is being actively studied. These drones fly a specified path and perform repetitive tasks. if the drone system will detect objects in real time, the performance of these mission flight will increase. In this paper, we implement object detection system and mount GPU acceleration to maximize the efficiency of limited device resources with drone video using Tensorflow Lite which enables in-device inference from a mobile device and Mobile SDK of DJI, a drone manufacture. For performance comparison, the average processing time per frame was measured when object detection was performed using only the CPU and when object detection was performed using the CPU and GPU at the same time.

A modular platform development technique was proposed to minimize development cost and development period by utilizing the already developed unmanned Aerial target AVT, which has been operated and verified for many years. New Mission Profile was designed and structural analysis was performed through finite element analysis (FEA) by analyzing mission requirements for visual short-range, non-visible mid-range, and long-range targets. The targets are used for guided missile anti-aircraft training. In addition, avionics systems including flight control computers for autonomous flights were developed to verify their conformance by performing launcher take-off tests with rapid acceleration changes and autonomous flight tests at a maximum speed of 300km per hour.
