Abstract

Unmanned aircraft systems (UAS) are defined as the system whose components include the necessary equipment, network, and personnel to control an unmanned aircraft. In the past, UAS were predominately operated for military operations. However, nowadays, the applications of UAS to commercial area are explosively augmented and UAS are being expected to be integrated in national airspace. Therefore, the need for the standardized datalink systems rapidly and the development of control and non-payload communication (CNPC) system are being processed for integration in national airspace in United States and Europe. In this paper, the technology trends for UAS CNPC datalink are explained and presented the performance evaluation results for CNPC system, which is the modified version of IEEE 802.15.4 ZigBee system.

무인 항공 시스템 (UAS)은 무인 항공기 운용에 필요한 장비, 네트워크 및 운용 인원을 포함하는 시스템을 통칭한다. 이러한 무인 항공 시스템은 과거 군사적인 목적으로 주로 이용되었으나, 최근 기술 발전에 힘입어 점차 민간용 시장으로 확대되고 있으며, 국가 공역내 통합되어 시장 규모가 급격히 성장할 것으로 예상된다. 따라서, 공역내 안정적인 통합을 위해 표준화된 무인기 제어 및 비임무용 (CNPC; control and non-payload communication) 통신시스템의 구축 필요성이 증대되고 있으며, 미국, 유럽을 비롯한 선진국에서는 높은 신뢰성을 제공 가능한 제어용 통신 기술 개발을 진행하고 있다. 본 논문에서는 무인 항공 시스템의 CNPC 데이터링크의 기술개발 동향을 기술하고, IEEE 802.15.4 ZigBee 시스템을 개량한 CNPC 시스템의 성능 분석 결과를 제시한다.
