The paper deals with the design and implementation of Navigational Aids Training Simulator (VR-NATS) by Virtual Reality (VR). To gave interaction and immersible training situation to the user, prototype VR-NATS was developed based on the object-oriented operating system with 3D objects of navigational aids. Using the VR-NATS we created virtual navigational aids. As results from the assessment tests, students can obtain IALA (International Association of Lighthouse Authorities) rules of the navigational aids exactly and quickly comparing with conventional education methods. Thus, we found that he proposed VR-NAT is very effective for the next-generation simulation system.

IALA Waterway Risk Assesment(IWRAP)에서 선박의 충돌확률은 기하학적인 선박의충돌확률(geomatric probability)에 인과관계 확률(causation probability) 곱한 값으로 해당수역의 양적인 충돌확률 평가에 이용되고 있다. 이를 통해 목포대교부근에 통항하는 선박의 선종별 충돌확률 및 입출항 선박 전체 충돌 확률 값을 분석하고자 한다.

전통적인 항로표지는 빛, 형상, 음향, 전파 등을 이용하여 선박의 위치를 인식하거나 장애물의 위치 정보를 제공하는 해상교통 시설물로서 해상에서 선박의 안전 운항을 지원한다. 한편, 4차 산업혁명과 미래 해상환경 변화에 대응하기 위해 국제항로표지협회(IALA)에서는 항로표지 기반 정보를 통합하여 디지털화와 표준화에 노력 중이며, 자율운항선박의 도입될 예정이다. 이에 자율운항선박이 활용할 수 있도록 디지털 정보를 생성하고, 이를 디지털 항로표지 형식으로 변경하여 자율운항선박에게 제공하고자 한다.

국내에 설치된 여러 종류의 항로표지를 체계적으로 관리하기 위한 '항로표지 전산관리 시스템'이 존재한다. 하지만 현행 전산관리시스템은 IALA S-201(항로표지 기본정보), S-124(항로표지 변경정보), S-125(항로표지 긴급정보)데이터 표준을 기반으로 한 항로표지 정보 서비스 대응에 한계점이 있다. 또한, 미래의 스마트 항로표지 정보, 장비에 대한 추가 센서 정보, 새로운 해양자원 서비스에 대한 정보관리의 확장성을 위하여 새로운 '스마트 항로표지 정보관리 시스템'을 개발하고 있다.

Aids to Navigation (AtoN) is a marine traffic safety facility used to facilitate the safe and efficient movement of shipping and enhance the protection of the marine environment by the regulations or guidelines of The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). Our country is managing AtoN to provide consistent services for AtoN users, although an average of 141 AtoN accidents occur annually. An AtoN accident forces non-planned work on the managers to resort the function, and causes psychological anxiety for its users, ultimately resulting in economic losses. This study developed the Social Cost evaluation model of AtoN accidents. The model can be used to quantify the manager's economic activities related to the shutdown and recovery, as well as the cost associated with the inconvenience to AtoN users. The Social Cost evaluation model of AtoN accidents is proposed as the sum of the encounter cost, administration cost and risk cost.

In order to prepare for increasing performance requirement for Differential Global Navigation Satellite System (DGNSS) services of International Maritime Organization (IMO) and International Association of Lighthouse Authorities (IALA), this paper focuses on design of network-based Automatic Identification System (AIS) reference station system that can perform the functionality of Differential Global Positioning System (DGPS) reference station in an AIS base station system. AIS base station receives the differential corrections from the DGPS reference station, and it is not a method for transmitting the received differential corrections to onboard AIS units, but it is a method for generating the optimized differential corrections for onboard AIS units in AIS coverage. Therefore this paper proposes an algorithm for generating the differential corrections at AIS reference station, and performs the performance assessment of the proposed algorithm based on DGPS correction data measured from a DGPS reference station. Finally this paper discusses the test results and efficiency of the proposed system.

Traditional rotation type large beacon was characterized by frequent failure, long repair time and high cost etc. These problems are caused by traditional light sources(metal halide lamps or tungsten halogen lamps). In order to solve these problems, IALA standards-based(efficiency and reliability) large LED beacon technologies are needed. we developed by applying a LED. The object of the this project, to design a reflective optics and the high power LED lighting engine module. And to develop a rotational speed control system for controlling flash pattern of beacon. As a result, to develop of LED beacon for landfall mark that distance to reach the light 20NM to 27NM.

The IVEF service is the draft standard designed for exchange of information on sea traffic between the vessel traffic systems and between the vessels. Standardization of this service is under way as a part of the next-generation navigation system, called e-Navigation. The International Association of Lighthouse Authorities (IALA) suggests, on its recommendation V-145, the IVEF service model and the protocol for provisioning of this service. But the detailed configuration of this service must be designed by the users. This study suggests, based on the basic service model and protocol provided in the recommendation V-145, the implementation of the J-VTS middleware which will facilitate exchange of information on sea traffic. The J-VTS middleware consists of various components for providing the IVEF service and for processing the IVEF message protocols. The vessel traffic systems and the vessels corresponding to upper-layer applications may use the IVEF service with the functions provided by the J-VTS middleware, and the services are designed to be accessed according to the security level of users.
