  • Even after the introduction of Global Maritime Distress and Safety System (GMDSS), many maritime accidents occur. A method of transmitting a rescue signal when a person falls into the water from a ship is currently being researched and developed in various ways, but no products have been developed that use frequencies allocated for maritime mobile service. Accordingly, in this study, we designed and produced a man-over-board (MOB) device by applying Group B AMRD technologies, which were adopted through the latest revision of the International Telecommunication Union (ITU). In addition, a receiver and user interface were built to verify the performance of the transmitter, and we confirmed that it can be used in conjunction with existing electronic charts. This MOB device satisfies the general and technical requirements of Group B AMRD using AIS technology and uses integrated components for miniaturization for easy portability in a maritime environment. We expect that it will achieve excellent AIS communication and be essential in rapid response and safety in emergency scenarios.

  • 1998년 도입된 GMDSS 제도의 현대화를 위한 프로젝트가 2012년부터 IMO 주관으로 추진되고 있다. 이와 관련하여 ITU에서는 2016년부터 전파규칙 개정을 위한 논의가 시작되었으며, 올해 11월에 최종 개정안이 확정될 예정이다. NAVDAT 및 VDES 같은 신규 무선설비들의 도입이 검토되고 있으며, Iridium 위성 시스템이 GMDSS 추가 위성시스템으로 승인되어 관련 후속조치가 논의되고 있다. 본 논문에서는 최근 해상통신분야의 국제회의 동향을 분석하고 이에 따른 우리나라의 대응방안을 제시하였다.
