한국전자통신연구원(ETRI)에서는 방송통신위원회의 “다원화 항법주파수 감시 및 이용기술 개발” 과제를 2011년 부터 수행하고 있다. 이의 일환으로 항법주파수 감시를 위한 위성항법주파수(GPS) 혼신원 감시시스템을 개발하고 있으며, GPS L1, L2 신호에 대하여 혼신신호를 검출하고, 혼신원의 위치를 파악하는 기능을 수행한다. 한국전자통신연구원에서는 2011년 북한의 GPS 전파교란에 대한 대응으로 GPS 혼신원 감시시제품을 전방에 설치하였으며, 2012년 4월에 있은 북한의 GPS 전파교란에서 교란신호를 정상적으로 검출하였다. 본 논문에서는 2011년과 2012년에 있은 북한의 GPS 전파교란 경향을 분석하여 북한의 전파교란 변화방향에 대하여 살펴보고, GPS 전파교란에 대한 대응으로 설치한 혼신원 감시시제품의 설치 및 운용 상황을 살펴본다.
