Abstract

VHF Omnidirectional Radio range(VOR) is used as an aircraft navigational aid. The VOR is a short-range air navigation system providing aircraft with its bearing relative to the ground station. The accuracy of a VOR must be checked in accordance with the current ICAO, FAA and domestic regulations. The primary purpose of performing VOR station ground checks is to minimize the need for expensive flight checks by determining the amount and direction of any course bearing inaccuracies being transmitted. In this paper we present current and advanced way of monitoring of VOR system. We verify this way by field test of the monitoring and it is a high performance way to achieve an improvement in accuracy and an effect compared to present monitoring system.

VHF Omnidirectional Radio range (VOR)은 항행안전시설로 ICAO (International Civil Aviation Organization) 및 국내법규에 의해 1~2개의 고정된 지점에서 모니터용 안테나를 통해 전파의 상태를 감시하도록 하고 있다. 본 논문에서는 수신된 전파의 복조 파형을 이용하여 VOR의 전파를 감시하는 방안을 제안하였다. 제안된 방식은 기존 데이터방식의 단점을 보완하여 약 30%를 차지하는 불감지역이 제거되었고, 측정 지점보다 최대 좌우 20도 범위의 방위각에 대한 전파를 감시할 수 있었다. 시각적 분석을 통해 전반적인 전파패턴 감시 그리고 전파왜곡의 원인이 되는 대략적인 방위각도 일부 예측할 수 있음을 시험을 통해 확인하였다.
