해양분야의 새로운 패러다임으로 논의되고 있는 e-navigation 정책의 핵심은 공간적으로 연속된 정보의 제공 기술과 제공될 정보의 수집, 분석, 표현 기술이라 할 수 있으며, 핵심 구성요소로 해상통신 서비스의 연속적인 제공을 위해서는 기존 통신 장비와 앞으로 요구되는 광대역 통신 장비 간에 Seamless한 통신 서비스가 제공될 수 있어야 한다. 이를 위해서 SDR 기술을 통한 다중모드 해상 무선통신 지원이 필요하며, 원거리 통신의 주요 기술 중 하나인 위성통신망을 독자적으로 보유하지 못한 우리나라의 현실을 감안할 때, 기존 지상파 무선통신 기술을 e-navigation 체계 내에 도입하여 활용할 수 있도록 관련 기술과 적용 방안이 필요하다. 본고에서는 해상무선통신 기술 및 서비스 제공 체계 분석을 통하여 해상 무선통신 기술 특성을 파악하고, SDR 제공 플랫폼의 하드웨어 및 소프트웨어 구조 분석을 통하여 해상무선통신 다중모드 운영을 위한 SDR 적용 범위를 도출하였으며, 향후 SDR 기반 해상 통신시스템 플랫폼 제공 방안을 도출하고자 한다.
