초록

최근 국내외 해상환경은 국제 해상 물동량 증가 및 활발한 해상 레저 활동으로 인하여 교통량이 증가함으로써 해양 사고의 발생 빈도가 높아지고 있는 추세이다. 이러한 해양사고를 줄이기 위해서 선교에는 항해사의 부담을 감소시키며 정확한 의사결정을 지원하기 위하여 다양한 종류의 항행 안전장비가 존재하고 있다. 그러한 장비들 중에서 선박자동식별장치의 경우 선박 자신의 정보를 송출하고 동시에 다른 선박의 정보를 받아들여 주위 상황판단에 도움을 주는 매우 중요한 시스템이나, 오류가 발생했을 경우 잘못된 정보를 주기적으로 송출하기 때문에 해당 정보를 이용하는 육상 관제사나 항행 중인 항해사의 의사결정에 지장을 주는 경우가 자주 발생한다. 이 연구는 AIS로부터 수신되는 선박 정보들의 신뢰도 및 정확도 향상을 위한 AIS 에러 데이터 및 필드 보정 알고리즘을 제안한다.

The domestic maritime environment shows higher frequency of maritime accidents amidst greater traffic volume arising from increasing international seaborne trade and maritime leisure activities. To reduce such maritime accidents, there exist various kinds of safety navigation devices in the ship bridge aimed to mitigate burdens of navigators and support their accurate decision making. Amongst is the AIS considered very important, which is an automatic tracking system to assist understanding of the circumstances in the vicinity by receiving information of other ships and also sending its own; where the information contains errors initially, however, such wrong information is periodically transmitted, accordingly giving rise to hindrance sometimes in decision making by shore operators or ship navigators at sea. This study is to propose the error data and field management algorithm using fuzzy theory toward improving reliability and accuracy in ship related information received from AIS.
