The intelligent maritime traffic information service provides a service to prevent collisions and stranding of ships based on the location information of ships periodically collected from ship equipment such as LTE-Maritime transceivers and AIS installed on ships. provided in real time. However, the above service may reduce the reliability of ship location information because GPS location information for measuring the ship's location may be cut off during transmission through LTE-Maritime or AIS networks, or phenomena such as location jumps and delays may occur. This study aims to estimate reliable position information to some extent even in an abnormal section through ship position prediction based on the existing received position information using the Kalman filter, which is an optimal estimation filter based on probability.

AIS(Automatic Identification System) is a key of maritime information system to prevent maritime accident through communication among any adjacent ship and to establish information base by fusing information collected from ships with other information. The AIS information includes various potential information, but it is not easy to use due to insufficiency storing and management. Furthermore, we need AIS transponders to acquire the information. In this paper, we propose the vessel positional information service using AIS and XML. We decode the AIS information from the NMEA-0183 encoding data and store the AIS information to the database and provide the access service in the internet using XML.

선박자동식별장치(AIS)는 선박의 선명, 제원 등 선박 정보, 운항정보 등을 선박과 선박 간, 선박과 관제센터 간 자동 송수신하는 장치다. 현재 국내에서는 전국 통합망 구축 사업 완료를 통해 AIS와 시스템이 본격적으로 운용되고 있다. 이러한 AIS 정보는 선박 대 선박 간의 충돌회피, 연안국이 불분명한 선박 및 그 화물에 대한 정보 획득, 선박 대 육상간의 통항관제를 위하여 사용된다. 하지만, 어선들은 생계와 관련된 어망의 위치가 노출되기 때문에, AIS 사용을 꺼려한다. 본 논문에서는 어선들의 위치가 노출되지 않도록 위치 정보를 암호화하고 인증하는 신뢰성 있는 AIS 통신 프로토콜을 제안한다.

When a boating accident, such as a January number three, the customer's risk management issues emerged. Ships and accident risk in confined spaces such as risk management to locate the customer and dangers of probation is available. In this paper, aboard after consent to obtain information for customers to wrist to customers, webbing or portable device embedded in devices and Wireless sensor information Input was attached, disposable consumer information. Customer on board the ship setting for location analysis and positioning according to information communication protocol, ships, each customer's real-time location information on the screen, 3 the foundation of d customers on the floor Can be designed to inform. Threshold designed to reduce the error of the information to analyze the position in current position and errors. Also, to system attacks would control the situation of accident and emergency jaenanguk server with real-time information transmission of information outside the emergency during a disaster, search and Disaster relief to be possible.

선박에 의한 해난사고의 대부분을 차지하고 있는 충돌과 좌초를 예방하고 안전항행환경을 확보하기 위해서는 선박들의 교통량 정보 및 위치정보, 해상환경정보를 얻지 않으면 안 된다. 본 연구에서는 인공위성데이터를 통해 얻어진 선박정보를 추출하는 방법에 대해서 조사하고, 다시 얻어진 선박정보를 이용해서 장래위치에 있어서의 해상교통환경 시뮬레이션을 했다. 즉, 장래 해상교통상황을 정량화 된 값으로 표현하여 자동차용 교통신호와 비슷한 선박들의 교통제어신호를 제공함으로써 해상교통안전을 확보할 수 있는 시스템의 기초적 연구결과를 제시했다.

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.

원격제어선박의 운항상태를 파악하고 제어신호를 보내기 위해 선박에 수집되는 각종 센서 및 기관정보가 육상제어센터에 전송되어야 한다. 통신수단 별로 전송속도 및 대역폭이 다르며, 선박의 위치에 따라 가용한 통신수단이 다르다. 선박이 육지와 가까워질수록 선박의 밀집도와 통행량이 많아지므로 수집해야 할 정보의 종류도 많고 속도도 빨라야 한다. 이 문제를 해결하기 위해 육상제어 센터에서 선박의 위치에 따라 통신수단을 변환하여 사용할 수 있도록 선박-육상간 통신망을 구축하였다.

This system configures a position Sensor as installing on the ship and a guidance system docking of ship what distinguish of the ship about the use and size. The maintain system is received the result of distinction via UWB reader. This system send a information of ship of docking position to user. Thus it suggests the safety to prevent from crash among ships and saves energy and stop waste. The proposed system periodically updates the information of docking position of the ship and monitors in real-time according to the user's request from personal mobile devices. In this paper, we implement of a guidance system Testbed for docking of the ship using position UWB sensor. And user is provided convenience to find easily user's ship in docking area through user interface with Java. Addedly it is possible to prevent ship theft.

AIS ship position transmitted from ships has been used position data generated by GPS, whose range of error is approximately 30nm. However, precision enhancement of the ship's position could be possible using DGPS correction information. More precise and accurate AIS ship position could be obtained broadcasting DGNSS Message(AIS Message 17) from ships without high-priced DGPS Beacon Receivers.
