Abstract

Before GBAS ground systems is installed at the airport, the site survey is needed to determine the suitability of proposed GBAS candidate sites depending on the siting requirements. Therefore, analysis of GPS signal reception environment, one of the site survey steps, is required. In this paper, the number of visible satellites, GPS signal strength, multipath error, radio frequency interference and predicted availability were analyzed using the GPS data of Gimpo International Airport measured by PortaSAT equipments and the analysis results were represented.

GBAS 지상시스템을 공항 내 설치하기 위해서는 장비 설치시 요구되는 각종 요구조건을 최대한 충족시키는 최적의 후보지 선정이 필요하다. 이를 위해 공항 내 GBAS 지상시스템 설치후보지에 대한 GPS 위성신호 수신환경 분석이 필요하다. 본 논문에서는 김포공항 내 GBAS 지상시스템 설치후보지에서 미국 Honeywell사의 PortaSAT 장비를 이용하여 수집한 GPS 데이터에 대해 가시위성수, GPS 신호세기, 다중경로오차, 신호간섭, GBAS 시스템 가용성 등을 분석하고 그 결과를 제시하였다.
