  • Unmanned Aerial Vehicle (UAV) is diversely utilized in our lives such as daily hobbies, specialized video image taking and disaster prevention activities. New ways of UAV application have been explored recently such as UAV-based delivery. However, most UAV systems are being utilized in a passive form such as real-time video image monitoring, filmed image ground analysis and storage. For more proactive UAV utilization, there should be higher-performance UAV and large-capacity memory than those presently utilized. Against this backdrop, this study described the general matters on proactive software platform and high-performance UAV hardware for real-time target tracking; implemented research on its design and implementation, and described its implementation method. Moreover, in its established platform, this study measured and analyzed the core-specific CPU consumption.

  • Given that the utilization of Unmanned Aerial Vehicles (UAVs) is recently increased, a variety of UAV control methods are being applied. In general, it has been used a lot to directly control a UAV via manipulator. However, tangible user interface is required to control UAVs accurately. This paper proposes a method for controlling an UAV based on multiple Myos. The UAV is connected to a ground control station and then controlled by Myos. Intuitive control is possible by controlling the UAV using tangible user interface.

  • Recently, UAV manufacturers are developing UAV system in a form that can be controlled by CS regardless of UAV kind and using STANAG 4586 interface standard considering Interoperability. STANAG 4586 is a NATO military standard developed to control various UAVs with standardized equipment. In such a case, UAV handover will inevitably occur and it is one of the most important function for safe UAV flight in platform using STANAG 4586. In the future combat situation where collaboration between AV and UAV is anticipated, seamless handover of UAV is a part of continuous research. In this paper, we propose requirements for UAV handover based on ARP 4761 safety assessment and analyze feasibility of the requirements by comparing UAV handover process in STANAG 4586. As a result of the comparative analysis, the proposed handover requirements based on ARP 4761 includes all the handover procedures of STANAG 4586 and present additional considerations for SOP creation and CS development. Applying the proposed handover requirements in the UAV development process can reduce the probability of loss of UAV control over the handover process and it can be expected to help improve the safety of UAV.

  • To operate UAV in the civil airspace, the airworthiness of UAV system have to be proven by the civil certification system. However, it is difficult for UAV to be certified by the existing certification system because the existing certification system has been developed for the manned aircraft. So, many civil aviation authorities and research institutes are studying developing airworthiness standards for UAV certification. To develop an airworthiness standards for UAV, the airworthiness level of safety have to be established based on UAV categorization. I would like to introduce an quantitative methods for establishing airworthiness level of safety of UAV based on UAV categorization and example of Smart UAV.

  • Recently, an UAV using green energy for propulsion has been developed due to exhaustion of fossil fuel. This aircraft runs on electric motors rather than internal combustion engines, with electricity coming from fuel cells, solar cells, ultracapacitors, and/or batteries. Especially solar cells are installed in HALE UAV and flight tests are performed in the stratosphere. Although the solar powered UAV has the advantage of zero emission, its energy conversion efficiency is low and operation time is limited. Therefore, the solar powered UAV has been designed to operate with the secondary battery obtaining flexibility of energy management. In this study, we suggest the new operational concept of the solar powered UAV using directed-energy rayed from the surface of earth to UAV. An UAV is able to secure additional power through attaching solar cell to the lower surface of elevator. As a result, the additional energy supplied by directed-energy can improve the energy management and operational flexibility of the solar powered UAV.

  • 무인항공기(Unmanned Aerial Vehicle, UAV)를 활용하여 넓은 범위를 감시하기 위해서 조종자가 반복적으로 같은 경로를 따라서 UAV를 비행시키는 것은 관리 및 운영에 필요한 비용과 시간 문제가 발생한다. UAV로 넓은 지역을 감시하기 위해서는 UAV의 자율 비행 연구가 필요하다. 전통적인 접근 방법은 GPS를 기반으로 이동할 위치를 연속적으로 설정해서 비행 경로를 설정한다. GPS 기반의 경로 설정은 비행 경로에 장애물이 없을 때 적합하다. 장애물을 고려한 비행을 위해서는 모터프리미티브 기반의 비행 기법이 필요하다. 이 논문에서는 UAV를 자율 비행시키기 위한 모터프리미티브의 구조를 제안한다. UAV의 비행 경로를 설정할 때 비행할 위치를 직접 설정하지 않고 감시할 위치를 설정해서 모터프리미티브를 정의하는 기법을 소개한다. 이와 같은 방법은 UAV가 감시할 위치가 사전에 정의될 때 조종사가 UAV의 경로를 쉽게 설정할 수 있다.
