무인항공기는 일반 유인항공기와는 다르게 크기의 제한이 없다. 또한 작은 사이즈의 무인항공기는 적은 인원의 투입으로도 항공기 각 분야의 검증이 가능하므로 소형화된 무인기는 여러 회사 및 연구원 학교등에서 개발되고 있다. 항공기의 크기가 작아지게 되면 운영요원의 숫자 또한 작아지게 되고 이로 인하여 쉽게 이동이 가능하고 운영이 가능한 이동형 무인항공기 지상통제 시스템의 요구가 생기게 된다. 본 논문에서는 한국항공주우연구원의 소형 무인기를 운영하기 위해 개발한 이동형 무인항공기 지상관제 시스템에 관하여 기술 하였다.

In the SORA methodology developed for the operational risk assessment of a specific category of operation of a UAS, the ground and the air risk levels are determined, and a SAIL indicating the level of assurance and integrity for the corresponding risk is assigned, and accordingly, the operational safety level for the proposed operation. Objectives should be demonstrated at an appropriate level of robustness. Because of the nature of the specific category of operation, people on the ground are the first risk subjects to be considered. The resulting ground risk class plays an important role in the allocation of SAIL. In this paper, the impact on SAIL and OSO according to the final risk level and the reduction of the level through the determination of the ground risk level and the application of mitigation measures among risk assessments for specific categories of UAV operation was investigated.

The military is facing an era in which it must take advantage of technologies related with the 4th Industrial Revolution. The representative of the final application of the 4th Industrial Revolution technology is the unmanned system. Many unmanned systems have not yet been harnessed to the army, and it is assumed based on literature studies that improving familiarity with unmanned systems will have a positive effect on force strength in the future. To verify these assumptions, the structural equation model(SEM) was used for quantitative analysis. The results suggest that the increase in familiarity with unmanned systems induces the increase in availability of unmanned systems in each field, which eventually raises the expectation that overall ground force strength will increase. These results imply that the military should reinforce the curriculum that enhances the familiarity of the unmanned system in military education system.

Nowadays, there are significant interests in real-time remote control using wireless networks. In implementing real-time remote control, one important factor is delay performance of real-time control message. Especially, the technique to reduce jitter of delay is necessary in transmitting periodically real-time control message. In this paper, we proposed synchronized transmission to reduce jitter of delay, when real-time control message was transmitted through wireless networks. The proposed transmission kept synchronization between source node and wireless transmitter and controlled transmission instance to transmit real-tie control message with fixed delay in wireless networks. According to results of experiment in military unmanned vehicle system, the proposed transmission reduced jitter of delay as 32% as that of a non-employing case.

Unmanned Aerial Vehicles (UAV) that are piloted without human pilots can be commanded remotely via frequencies or perform pre-inputted missions. UAVs have been mainly used for military purposes, but due to the development of ICT technology, they are now widely used in the private sector. Teal Group's 2014 World UAV Forecast predicts that the UAV market will grow by 10% annually over the next decade, reaching $ 12.5 billion by 2023. However, because UAVs are primarily remotely controlled, if a malicious user accesses a remotely controlled UAV, it could seriously infringe privacy and cause financial loss or even loss of life. To solve this problem, a secure channel must be established through mutual authentication between the UAV and the control center. However, existing security techniques require a lot of computing resources and power, and because communication distances, infrastructure, and data flow are different from UAV networks, it is unsuitable for application in UAV environments. To resolve this problem, the study presents a lightweight UAV authentication method based on Physical Unclonable Functions (PUFs) that requires less computing resources in the ground Control and Non-Payload Communication (CNPC) environment, where recently, technology standardization is actively under progress.
