Abstract

Unmanned aerial vehicles(UAVs) operating in the military for various purposes are designed to transmit information collected according to the purpose to GCS(Ground Control System), and to transmit/receive the vehicle's operational control and status information using wireless communication(or datalink). Currently, the military UAV systems in operation in Korea use unique communication methods, protocols, and message structures for each system. Among these, the Division UAV is designed to transmit fixed size TM/TC data repeatedly and the Corps UAV is designed to transmit aperiodic TM/TC data to the variable length of the message-based. In this paper, we analyze the TM/TC data protocol of existing military UAV systems and present data protocol design method which is considered to be more efficient in wireless communication environment applied to equipment under development. And we will discuss issues to be considered for standardization of technology for ensuring interoperability with many UAVs or newly introduced UAV systems.

다양한 목적으로 군에서 운용되고 있는 무인기는 목적에 따라 수집된 정보를 무선통신을 이용하여 지상의 통제장비로 전송하고 비행체의 운용제어 및 상태정보를 송수신 할 수 있도록 설계되어 있다. 현재 국내에서 운용 중인 군용 무인기 체계는 각 체계별 고유 통신방식과 프로토콜, 메시지 구조 등을 이용하고 있다. 이 중 사단급 무인기는 고정크기의 TM/TC 데이터를 반복 전송하는 방식으로 설계되었고 이와는 다르게 차기 군단급 무인기는 TM/ TC 데이터를 메시지 기반의 가변길이로 비주기 전송하도록 설계되었다. 본 논문에서는 기존 방식으로 설계된 시스템의 TM/TC 데이터 프로토콜을 분석하고 현재 체계개발 중인 장비에 적용되어 무선 통신환경에서 더 효율적이라 판단되는 데이터 프로토콜 설계방안에 대해 제시하였다. 또한 향후 다수의 무인기 간 또는 새로 도입되는 무인기 체계와의 상호운용성 보장을 위한 기술 표준화를 위해 고려해야할 사항 등에 대해 논하고자 한다.
