초록

급격하게 변화하고 첨단화 되어 가고 있는 해상운송 기술의 정점은 자율운항선박이 될 것으로 예상된다. 자율운항선박에서의 다양한 서비스의 구현은 선박 중심 네트워크인 S2X 통신체계를 통해서 가능할 것이다. 하지만 기존의 통신은 서비스 트래픽 포화, 요구 기능에 부합하지 못하는 등의 문제가 있어 추가적인 통신 기술의 선제적 도입이 필요하다. 본 연구에서는 자율운항선박에 적용될 S2X 통신의 개념을 재정립하고 요구 기능을 도출하여 최종적으로 활용이 가능한 주파수를 선정하였다. 이를 위해 도출된 통신 요구 기능에 적합한 후보 주파수 군을 도출하고 전문가 합의법을 통해 최종적으로 우선 적용이 가능한 통신 주파수를 선정하였다. 향후 해당 주파수에 대해 실험을 통한 검증 등 추가적인 연구를 통해 자율운항선박 서비스 구현에 활용이 가능할 것으로 기대된다.

The pinnacle of rapidly changing and advancing maritime transportation technology is expected to be the Maritime Autonomous Surface Ship (MASS). The implementation of various services within the MASS is likely to be feasible through the ship-centric network known as the S2X communication system. However, existing communication systems face issues such as service traffic saturation and failure to meet demanded functionalities, necessitating the proactive introduction of additional communication technologies. In this study, the concept of S2X communication for the MASS was redefined, deriving required functionalities and ultimately selecting frequencies suitable for utilization. Candidate frequency groups suitable for the derived communication requirements were identified, and communication frequencies prioritized for the initial application were chosen through expert consensus. It is anticipated that through further research, including experimentation to validate these frequencies, they could be utilized in implementing services for autonomous ship navigation in the future.
