초록

항공 수요가 지속적으로 증가함에 따라 레이더를 이용한 항공 감시가 한계에 다다르면서, 새로운 항공 감시 기술인 ADS-B가 등장하였다. ADS-B는 레이더에 비해 높은 위치 정확도와 빠른 갱신 주기를 제공하며, ADS-B 송수신기를 장착한 항공기간에는 서로의 위치 정보를 확인할 수 있다는 장점을 갖는다. 하지만 모든 항공기가 ADS-B 송수신기를 탑재하지는 않으며, 서로 다른 ADS-B 데이터 링크를 사용하는 항공기 간에는 위치 정보의 송수신이 불가능하다는 단점이 있다. 이러한 ADS-B의 단점을 해결하기 위해 레이더가 감시 중인 항공기의 정보를 방송하는 TIS-B 서비스와 ADS-B 데이터 링크를 교차하여 ADS-B 신호를 방송하는 ADS-R 서비스가 개발되었다. 본 논문에서는 ADS-B 감시 자료와 레이더 감시 자료를 통합하여 TIS-B 서비스와 ADS-R 서비스를 함께 제공할 수 있는 항공 교통 상황 방송 서비스용 중앙 집중형 TIS-B 서버를 설계하고 구현하였다. 구현한 시스템은 직접 구성한 ADS-B 지상 시스템과 연결하여, 비행 중인 항공기의 ADS-B 감시 자료와 레이더 감시 자료를 수신하고, 수신한 감시 자료를 이용하여 TIS-B 서비스와 ADS-R 서비스를 제공하기 위한 감시 자료를 생성하여 모의 방송을 하는 방법으로 검증하였다.

As a radar based air surveillance hits the limit along with the growing air traffic needs, a new air surveillance technology called ADS-B has emerged. ADS-B provides more accurate position information with a shorter interval, and aircraft equipped with ADS-B transponders can check each other's location. However not all aircraft are equipped with ADS-B transponders, and aircraft with different ADS-B data links cannot check each other's location. To address these problems a TIS-B service, which broadcasts information that a radar is tracking, and an ADS-R service, which cross-broadcasts information of different ADS-B data links, have been emerged. In this paper, we design and implement a centralized TIS-B server for broadcasting air traffic situation which is capable of providing a TIS-B service and an ADS-R service at the same time. The implemented TIS-B server has been verified with a configured ADS-B ground system, by receiving ADS-B surveillance data and radar surveillance data followed by generating surveillance data for providing a TIS-B service and an ADS-R service and simulating broadcast of those generated surveillance data.
