Abstract
본 논문에서는 위성항법신호감시국에 대한 핵심기술인 FPGA 기반의 위성항법수신기를 구현하여 갈릴레오 E1 및 E5 신호처리 동작검증 및 처리결과를 제시하였다. 성능 검증을 위해 시제품 형태의 위성항법안테나, 112MHz 샘플링 주파수 및 8비트 양자화 레벨을 제공하는 RF/IF 유니트를 이용하여 갈릴레오 시험위성인 지오베-B(GIOVE-B)로부터 E1 및 E5를 수신하여 이용하였고, 수신된 데이터에 대한 신호처리 수행을 통해, FPGA 기반의 항법수신기 모듈에서 갈릴레오 E1 및 E5 신호가 정상적으로 동작됨을 입증하였다.
