In this paper, the state-of-the-art IVEF Service based on e-Navigation System was represented. The unification of the data exchange format among maritime-related systems is one of vital user-needs of e-Navigation, advantageous in bringing maritime safety and security. This paper propose the method to exchange marine information in IVEF, as recommended by the IALA, between VTS centers and Korea's GICOMS as well as the government-related agencies. To achieve this, a system data flow was designed which it acts as client and server. It enables the sending and receiving of Radar and CCTV images in accordance with the IVEF recommendation document of IALA.

Navigation satellite systems (GPS, GLONASS etc.) provide three main services, i.e., positioning for location based services, navigation for multi-modal transportation services, and timing for communication and critical infrastructure services. They were started as military systems but were extended to civil service. Navigation satellite navigation system began with GPS in the USA and GLONASS in Russia at nearly the same time. Indian NavIC and Chines BDS announced their FOCs in 2016 and 2020, respectively and European Galileo and Japanese QZSS are catching up others. In these days, Navigation Satellite System, Positioning, Navigation, and Timing services are part of our daily life very closely. They are required for autonomous driving car, Unmanned vehicles like UAV, UGV, and UMV, 5G/6G telecommunications, world financial system, power system, survey, agriculture, and so on. The services among navigation satellite systems are very competitive and also cooperative one another. This article describes the status of these systems and evolution in the technical and service senses, which may be helpful for planning korea positioning system(KPS).

During the past several decades, the development of the maritime policy have been focused on the level of regulation based on the lessons from the individual accidents. Recently, the development of IMO e-navigation strategy has been discussed actively and has been focusing on the new frame and architecture based on the user requirements and definition of function and services for user requirements, which might produce the user-friendly policy, infrastructure and user service. For the new maritime ICT policy getting fusion of ICT and innovation of ship/ocean industry, the overarching methodology, as IMO e-navigation strategy, should be applied to primarily setup the architecture from the user requirements to technology. In this paper, we analyze the IMO e-navigation strategy procedure and provide the consideration and lessons for the strategic methodology to develop a new maritime ICT policy.

최근 국제적으로 e-Navigation을 지향하는 해상안전에 대한 국제적 기술개발 및 표준화가 활발하게 진행되고 있다. 이러한 국제적 변화와 더불어 국내에서도 차세대 해상교통관제기술개발의 필요성이 제기되어 왔다. 즉, 차세대 VTS(Vessel Traffic management Service)는 e-Navigation의 육상 시스템으로의 역할을 수행하기 위한 새로운 개념과 서비스가 도입되어야 하며 기존 시스템과는 차별화될 수 있는 요인이다. 따라서 본 논문에서는 차세대 VTS인 u-VTS의 개념과 구조를 정립하고 관련 서비스 요구 사항을 고찰하고자 한다.

국제수로기구는 수로정보의 활용과 상호 운용성 증진을 위해 S-100 표준을 개발하여 수로분야 제품표준 개발을 위한 프레임워크로 지정하였다. S-100 표준은 S-57 표준을 대체하는 것으로서, 전자해도 간행업무와 ECDIS 개발에 직접적으로 영향을 미치는 중요한 표준이라 할 수 있다. S-100 도입에 따른 산업계 핵심기술 개발차원에서 "국제 해양 GIS 표준기술기반 차세대 항행정보지원 시스템 개발과제"가 추진되었으며, 그 일환으로 차세대 ECDIS 개발에 요구되는 S-10X 시험데이터 연구를 수행하고 있다. 본 논문에서는 e-Navigation 테스트 베드, e-Navigation MSP(Maritime Service Portfolio), 국제수로기구 S-100 기반 제품 표준 사례, 국제수로기구의 S-100/S-101 테스트 베드 현황 등의 차세대 ECDIS 시험데이터 사례 분석을 통해 차세대 ECDIS 시험데이터 구축 범위를 식별하였다. 또한 그 동안 수행한 차세대 전자해도 데이터베이스 준비를 위한 기초기술 개발 내역을 소개하고자 한다.

e-navigation 전략은 선박의 출발항부터 도착항의 부두 접안에 이르는 전 과정의 안전과 보안을 위한 관련 서비스 및 해양환경 보호 증진을 위해 선박과 육상 관련 정보를 융합하여 통합된 수집, 교환, 표현 및 분석을 수행하는 체계를 말한다. 이는 기존의 선상 시스템과 육상 시스템에서의 유용한 정보들을 융합하여 통합시킴으로서 선박의 안전을 제공하고 나아 가서는 해상의 환경을 보호하기 위한 방법을 제공하기 위한 것이다. 이러한 e-navigation 전략의 기반 하에 기존 제공되는 선상에서의 IBS, 육상의 VTS 등 서비스 뿐 아니라, 원격 유지보수 서비스, 선내 통합 모니터링 서비스, 지능형 선박충돌방지 서비스, 지능형 연근해상 선박교통관제 서비스 등 다양한 통합화된 서비스 제공이 가능하다.

As the GPS(Global Positioning System) vulnerabilities were introduced, alternative systems to GPS backup have been studied for several years. Enhanced Loran(eLoran) as the worldwide ground-based supplementary radio navigation system was recommended as the cost effective alternative to GPS backup. Many efforts on adoption of eLoran as GPS backup have been presented. The US has been the leading role and announced that 70% enhancement for eLoran was established last year. However, the Obama administration cut off the eLoran budget on the fiscal year 2010 budget proposal while GAO's reports submitted that GPS service gap would be possible just some years later. Besides the US's condition, there are still many positive opinions on eLoran to GPS backup. This paper introduces the historical and technical aspects of eLoran and Korea's research topics.
