해상용 200mm 등명기를 대체하기 위해 2003년 최초로 국내에서 LED 등명기가 개발되었다. LED 등명기는 개발되어진 이래로 그 수요가 계속 증가하고 있으며, 기능 또한 많이 개선되어지고 있다. 그러나 현재까지 LED 등명기에 관한 심도 있는 분석이 이루어지고 있지 않다. 본 논문은 LED 등명기의 사용전검사시 색상별 부동광도 및 정기검사(3년) 시 부동광도 감소율 등을 통계조사를 통해 알아보고, 현재 진행중인 LED 등명기 수명실험의 2차년도까지의 결과를 토대로 현단계에서의 개선점을 찾아보기 위해 작성되었다. 또한 향후 계속적인 LED 등명기 성능 기선 연구에 기초자료를 제공하고자 한다.

Establishment and operation of Aids to Navigation in the process of port design, construction and management are crucial factor of maritime safety and collision prevention. According to the IMO SOLAS Chapter 5, regulation 13, the establishment and operation of maritime safety facilities are mandated for the competent authorities. The facilities of Aids to Navigations are moving to a concept of e-Navigation with state-of-the-art technology of radio navigation equipments such as AIS, DGPS and e-Loran from the traditional visual facilities (optics, shape), Although the autonomous maritime traffic system is a new trend, yet the traditional and conventional Aids to Navigation like lighthouses and beacons are still imperative for vessel's safe navigation. In this paper, for decision of service level of maritime traffic facilities to enhance the efficiency of visual navigation system management it was proposed the Aids to Navigation availability as an efficient management system incorporating the whole maritime traffic facilities under one management system. Comparison of foreign level of services and analysis of the theoretical background of them were analyzed and the proposed LOS was applied to Incheon area to evaluate the safety of navigation routes.

A key objective is to meet the requirements for safe marine transport and protection of the marine environment by providing a comprehensive mix of Aids to Navigation commensurate with the amount of traffic and the degree of risk. The development of e-Navigation is driven by the compelling need to equip the master of a vessel and those ashore responsible for the safety of shipping with modem, proven tools to improve the reliability of marine navigation and communications. Although position fixing using GNSS is widely used, radar and visual AtoNs continue to be needed to provide safe, secure and environmentally clean navigation. The paper considers the role, evolution and future provision of traditional aids to navigation in an e-Navigation environment from both a technical and mariner perspective.

It is said to be very difficult to maintain the aids to navigation such as buoys end lighthouses due to their geographical characteristics. This paper, as a part task of the construction of aids to navigation control center, describes the method to make the module for remote-controlling lighthouses and buoys. We become to be able nor only to get informations such as the condition of lights and batteries, but also to control remotely the aids to navigation by using microwaves so as to maintain them in good condition.

The restrictions concerning the use of the radio waves have become severe, the marine radar with low spurious is being developed. Therefore, it is necessary to develop aids to navigation as a radar beacon can respond to new type of marine radar. Because the system of radar in the future is an indetermination, new radar beacon should correspond to old and new radar system during a transition period. New radar beacon that is also able to respond to pulse radar, pulse compression radar and FM-CW radar were considered in these years in Japan. The sign of the response of Morse code in a new system is generated by the delay synthesis system. Computer simulation and actual examination using trial circuit were curried out. A big possibility was set up in the development of the new radar beacon that was able to correspond to old and new radar system. These results and the state of new radar beacon is mentioned in this paper.

Aid to navigation is a navigational aid facility that informs a sailing vessel of its location and direction as well as a location of a specific obstacle by means of a light, shape, color, sound, radio wave, etc. It can be valuable in improving the safety of day and night vessel navigation at sea. For the safety of the tug boat, the minimum equipment requirements for each type of tug boat are arranged. Despite these preparations, the collision accidents between tug boats, barges, and light buoys can occur when the tug boat turns due to the length of the tow-line, tidal current, and the barge's momentum etc. The purpose of this study was to propose the basic system that analyzes the physical relationship between two vessels regarding the tug boat-barge-light buoy dynamics and propagate the corresponding data through the aid to navigation management & operation systems in use at each regional oceans and fisheries.

The AIS(Automatic Identification System) is the useful equipment in order to promote the maritime safety and real time monitoring at the sea. In this study, the plan to construct the ubiquitous Aids to navigation is proposed. In order to verify the construction of ubiquitous Aids to navigation, the experiment on the sea was carried out and analyzed.
