인류의 활동 무대가 우주공간으로 확대됨으로써 우주기상에 의한 피해를 최소화 할 수 있는 조치가 요구됨에 따라 우주기상에 대한 감시 및 예 경보 업무가 필요해 졌다. 미국은 이미 우주기상 감시와 예보의 필요성을 인식하고 해양대기청(NOAA), 미 공군(USAF), 항공우주국(NASA), 내무부(DOI), 에너지부(DOE), 과학재단(NSF)이 연합하여 1996년 국가우주기상 프로그램(National Space Weather Program)을 수립.추진하고 있다. 특히 정부연구 기관인 NOAA 산하 우주기상예보센터(Space Weather Prediction Center; SWPC)와 미 공군 기상국(AFWA)은 우주기상 자료 생산, 수집, 자료 센터 운용, 연구 지원 및 예 경보 업무를 공동으로 수행하고 있으며 관련 자료 및 정보의 교환 등 매우 밀접하게 상호협력하고 있다. 최근 정부는 과학기술 7대 중점투자 분야별 중점육성후보기술로서 우주감시체계개발기술을 포함한 국가과학기술기본계획(577전략)을 수립 발표하였으며, 대한민국 공군은 향후 우주군 창설을 목표로 우주전력 기반체계구축을 계획하고 있다. 국방부는 2012년 전시작전통제권 환수에 대비한 독자적인 작전지휘능력 확보가 필요한 상황이며, 미래의 한국군 독자적 네트웍 중심 전장(NCW: Network Central Warfare) 체계 구축을 위해서는 미 공군의 "우주기상작전센터"와 같은 우주기상 예 경보 체계 구축이 요구된다. 이 연구에서는 군의 독자적 우주작전능력 확보를 위한 우주기상 예 경보 체계 구축 방향을 제시하고자 사전기반 연구를 수행하였다. 그 내용으로 우주기상에 대한 개요 및 우주기상의 변화에 따른 국내외 영향을 조사하고 국내외 우주기상 예 경보 시스템을 소개하고자 한다. 또한, 미공군의 우주기상 활용 상태를 점검하여 한국 공군을 위한 우주기상 예 경보 체계 구축 및 인력과 기술 확보에 대한 방안을 제시하고자 한다.

Despite growing international cooperation for maintenance of international peace and security, wars continue to occur due to conflicted state interests. Continuing conflicts has advanced development of various weapon systems such as global integrated intelligence, surveillance and reconnaissance. However, with a big increase in the number of civilian casualties caused by the weapon systems development, the international community has also advanced diplomatic efforts to minimize deaths of civilian and military personnel. Therefore, it is essential to observe the principle of discrimination between combatants and non-combatants when operating unmanned aerial vehicles (UAVs), better known as drones. Drones have become more capable of distinguishing combatants from non-combatants due to its high-tech prowess. In the operation of drones, any parties involved in combat or the war are responsible for mounting civilian casualties. In addition, it should comply with the principle of proportionality that calls for a balance between results of such action and expected military advantage anticipated from the attack. The rule of proportionality prohibits use of military force which may be expected to cause excessive civilian harm. Drones have been able to track and monitor targets for hours and select the accurate locations of the targets. The aim is to reduce civilian losses and damage to a minimum. Drones meet the standards of Article 51.4 of the Additional Protocol.

현재 우리나라는 군사적 용도의 우주전력은 전무한 실정이나, 군사차원에서 1992년 최초롤 우리별 1호를 발사한 이후 꾸준히 연구 개발을 해온 결과 현재는 세계에서 23번째 실용 위성 보유국이 되었으며, 2015까지 세계 10위권 위성보유국 대열에 진입하기 위한 국가 우주개발 중장기 계획을 수립하여 적극적으로 추진해 나가고 있다. 따라서 군에서도 주변국의 우주개발에 대한 경쟁에 뒤지지 않고 21섹이의 한반도 주변 전략환경을 우리에게 유리하게 진행시키기 위해서는 무엇보다도 우주의 군사력 활용이 필요하며 우주전력을 이용한 작전능력의 신장, 우주전력의 지원, 우주전투 능력 확보를 위한 장기적인 우주계획을 수립하는 등 군 우주분야의 발전이 절실히 요구되고 있다.

The U.S. National Aeronautics and Space Administration proposed a new concept of urban air mobility in the city's short-range air transport ecosystem in order to build a new low-altitude air, and the term uam is currently used worldwide. This paradigm is also being promoted by the Korean government with the goal of commercializing urban air transport services by 2025, and furthermore, the need to secure air maneuvers and transportation capacity is emerging due to the rapidly changing future operating environment and battlefield space. In other words, this study started to present the military necessity and military operation plan by introducing the 'Agility Prime' program of the US Air Force. 'Agility Prime' program was organized in order of background and concept of urban air mobility, development trend of Korean urban air mobility and analysis of the US Air Force's 'Agility Prime' program, and it is expected that this study will be followed by a follow-up study.

In this paper, there is a research for providing environmental data to reflect environmental effects to the simulation for the aviation weapon systems by the construction of the synthetic battlefield. The results of the aviation engagement simulation are able to differ by environmental effect. This paper analyzes the real aviation battlefield and designs the synthetic battlefield based on the analysis. In order to construct the designed synthetic battlefield, we collects the real environmental data for the atmosphere and structures the collected data using GIS (Geographic information system interpolation). The main objective of this paper is to design the synthetic battlefield based on the derived environmental factors from the analysis of the real aviation battlefield, and it constructs the designed synthetic battlefield by the collection of real atmosphere data. The constructed synthetic battlefield provides the environmental data which are requested from the distributed simulation system, and it makes the system reflect environmental effects to the simulation.

This paper presents a distributed task assignment algorithm for the suppression of enemy air defense (SEAD) mission of heterogeneous UAVs, based on the consensus-based bundle algorithm (CBBA). SEAD mission can be modeled as a task assignment problem of multiple UAVs performing multiple air defense targets, and UAVs performing SEAD mission consist of the weasel for destruction of enemy's air defense system and the striker for the battle damage assessment (BDA) or other tasks. In this paper, a distributed task assignment algorithm considering path-planning in presence of terrain obstacle is developed for heterogeneous UAVs, and then it is applied to SEAD mission. Through numerical simulations the performance and the applicability of the proposed method are tested.

The sea of the Korean peninsula has undergone various marine changes, including naval vessels, naval operational aircrafts, air force fighters, coastal airports and airfields. In particular, salt directly affected by the marine environment, equipment operating under a high temperature / high speed as the gas turbine is the high temperature corrosion (Hot Corrosion) caused by sulfur components and salinity of the fuel used. When the height of the demister (air intake) is less than 7 m, the salinity of the salt entering the sea increases and the corrosion increases rapidly. In addition, the weapon systems operating in the East Sea than in the West Sea showed a 17% increase in the corrosion rate due to the relatively high salinity scattered by saline, wind, and wave. In order to minimize the salinity inflow, it should be operated at more than 13 m from the sea to minimize rapid hot corrosion.

In this paper, we propose an allocation scheme for variable message packings to increase efficiency of military operation using Link-16 which is well-known for tactical data link by delivering imagery information rapidly. We propose a variable message packing scheme using COC waveform to support variable data rate under some coverage limitation. Variety of message packing makes Link-16 vary transmission rate appropriately for tactical environment. We also propose a allocation scheme to assign message packing to time slot properly. Finally we verify the performance and superiority of proposed ideas by simulations.

This paper deals with a development of night vision imaging system(NVIS) for the KO-1 aircraft. In the modern combat, NVIS has a tendency to be applied for night peculiar mission and pilot mission maximization. KO-1 aircraft, which was the first domestic applied NVIS, is forward air control acquired information of day/night enemy(foe) site and moving of enemy for low altitude flight. We have successfully finished a developmental requirement/criterion, development of system, and construction of test and evaluation through development of NVIS for the KO-1 aircraft. KO-1 aircraft is acquired timely initial operational capability.
