A Study on the Development of the Navigational Information Monitoring and Recording System

항해 정보 모니터링 및 기록 시스템 개발에 관한 연구

Recently, due to the several factors such as the advent of very large vessels and high-speed vessels, and the increase of the maritime traffic density at sea, the obligation, responsibility and burden of marine officers on duty for the safety of navigation has been highly escalated. Under these situations, if the appropriate and correct navigational information is given to officers at real time by means of certain integrated information processing system, these obligation, burden and danger can be reduced. This paper deals with the study on the development of the Navigational Information Monitoring and Recording System that can give and record the integrated navigational information based on the personal computer system installed on board. To construct this system, the interface unit which changes different signal types of navigational equipments to NMEA 0183 signal format and the application software to show the visual navigational information were developed. In this study, the navigation system of T/S HANBADA in Korea Maritime University was used in order to construct the actual system that can be utilized in other ships, and also the performance test was carried out several times to examine the performance of the system developed. It was proved that all functions of the system as designed worked smoothly through the performance test. Also this system could be operated easily and conveniently by every user.
