초록

IMO (International Maritime Organization)와 IALA (International Association of Lighthouse Authorities)는 VHF (Very High Frequency) 해상이동업무에서 음성과 데이터를 효율적으로 전송하는 향후의 디지털통신 시스템을 구현하기 위한 GMDSS (Global Maritime Distress and Safety System) 현대화와 E-navigation 등의 프로젝트를 진행하고 있다. IALA는 해상무선통신 계획을 발표하고 E-navigation을 위한 시스템 구성, 신기술 및 표준을 검토하고, ITU (International Telecommunication Union) R은 해상통신 시스템의 기술적 특성에 관해 규정하고 있다. ITU-R에서는 선박운항과 항만보안 및 항해안전을 지원하기 위한 스펙트럼의 효율적인 활용 연구로 WRC (World Radiocommunication Conference) 07, Resolution 357을 의결하고, IALA와 ITU WP5B는 기술개발 및 스펙트럼 문제를 협력하고 있다. WP5B는 권고문 ITU-R M.1842-1을 승인하여 VHF 해상이동업무에서 50kHz와 100kHz의 광대역으로 데이터 서비스를 제공할 수 있도록 규정하였다. 본 논문은 E-navigation을 위한 VHF 데이터 교환, VHF 육상이동업무에서 기지국과 이동국간 데이터전송, 권고문 ITU-R M.1842-1에 대한 분석 및 육상이동업무의 표준을 근거로 해상이동업무의 데이터전송 요구를 만족하는 시스템의 성능평가 방안에 대하여 제시하였다.

IMO and IALA have undertaken projects that GMDSS Modernization and E-navigation, which refer to "Future digital communications systems" for a more efficient transmission of voice and data communications in the VHF maritime mobile service. ITU has also resolved in WRC-07 Resolution 357 to study the use of spectrum-efficient technologies in order to provide for the operation of ship and port security and maritime safety systems. IALA and ITU WP5B have coordinated for the technical developments and the spectrum issues. Recommendation ITU-R M.1842-1 has approved by WP5B meeting. This revision provides a wideband data service both 50kHz and 100kHz in the VHF maritime mobile service. This paper has studied E-navigation, its needs for data exchange that includes explanations of the current methods for transmitting data by VHF that based in land mobile radio service. A further technologies trend is estimated for Recommendation ITU-R M.1842-1, that is based on the land mobile radio standards with some tailored to fit the needs of the maritime mobile service.
