The general ground control system has control and information display functions for the operation of a single unmanned aerial vehicle. Recently, the function of the single ground control system extends to the operation of multiple UAVs. As a result, operators have been exposed to more diverse tasks and are subject to task overload due to various factors during their mission. This study proposes an adaptive ground control system that reflects the operator's condition through the task overload measurement of multiple UAV operators. For this, the ground control software is developed to control multiple UAVs at the same time, and the simulator with six degree-of-freedom aircraft dynamics is constructed for realistic human-machine-interface experiments by the operators.

In this paper, a total operating environment equipped with onboard wireless communication systems and ground-based mission control systems is proposed for simultaneous operation of multiple UAVs. A variety of operating structures are studied and classified systematically based on types and usages of the components. For each operating system, the strength, weakness and reliability aspects are investigated. Based on these results, a proper operating system configuration is determined and components are developed for mission formation flight. Proposed system can make a formation flight of various UAVs, execute complex missions decentralizing mission to several UAVs and cooperate several missions.

오래 전부터 많은 컴퓨팅 시스템에서 기분적으로 제공되어지는 원리인 임무분리는 중대한 업무를 둘 이상의 사용자에게 나누어줌으로써 단독 사용자가 시스템을 손상시키는 것을 막도록 하는 것이 목적이다. 역할기반 접근통제에서 임무분리 원리를 제공하는 종류로는 정적 임무분리, 동적 임무분리, 기능적 임무분리, 객체기반 임무분리 등이 있다. 여기서 우리는 정적 임무분리를 만족시키는 모델로서 상호 배제 역할 쌍을 이용한 모델과 역할유형을 이용한 모델 그리고 상호 무관 역할 쌍을 이용한 모델을 제안한다

The purpose of this study was to address a Remote Airborne Control Simulator that could simulate manned-unmanned teaming (MUM-T mission) for fixed wing UAV. With rapid technological development of unmanned aerial vehicle (UAV), the mission capability of UAV has tremendously grown. The role of UAV extends from simple reconnaissance to highly automated wingman. Accordingly, the requirement of UAV ground simulator should be modified as well to meet function requirements for simulating a MUM-T mission. A developed remote airborne control simulator was developed for conducting fixed wing UAV MUM-T operation simulations on the ground. The newest MUM-T examples, usage, and application of the developed remote airborne control simulator for MUM-T simulation are also presented in this study.

In this paper, we propose a remote control station based on the awareness of various combat field situation in order for operating multiple unmanned ground vehicles. Our remote control station is capable of sending a variety of messages designed for carrying out the skillful movement for collaborate among unmanned ground vehicles, gathering the information related with combat field situation, and completing the assigned missions which are described by operator in advance. To verify the effectiveness of our proposal, we develop the sophisticated remote control station and conduct a great many remote operating tests for multiple unmanned ground vehicles.

정보시스템관리를 위한 위험분석시스템은 다수의 사용자가 각각의 역할과 임무에 따라 평가대상조직의 민감한 내공을 다루므로, 대상조직에 대한 역기능을 초래할 수 있다. 이에 위험분석시스템 자체의 보안을 위한 접근통제가 필요하다. 본 논문에서는 위험분석시스템을 위한 RBAC정책 모델을 제안한다. 제시한 모델은 위험분석시스템의 특성을 고려하여 연구되었으며, 역할의 상속성에 의한 권한남용 방지를 위해 금지적접근목록(n-ACL)을 적용하였다.
