Research On AIS Technology Realization In Yingkou VTS

Universal Automatic Identification System (AIS) comes into being in the 1990s, is a ship and shore-based broadcast automatic identification transponder system, operating in the VHF maritime band, is a new navigational system and a new maritime safety information system involving the modern communication and network and information technology. Its characteristics and capability will make it an outstanding new tool for enhancing the safety of ship navigation and efficiency of shipping traffic management.In order to building and developing AIS, MSC73 of International Maritime Organization (IMO) adopted the amendments to the SOLAS74 Convention in the MSC.99 (73) Resolution in 5 December 2000, the amendments will enter into force on 1 July 2002. According to chapter V of the amendments to the SOLAS74 Convention, all ships of 300 tons gross tonnage and upwards, when engaged on international voyages, all ships of 500 tons gross tonnage and upwards, when engaged on non-international voyages, all passenger ships shall be fitted with shipborne AIS equipment on a provided timetable.International Maritime Organization (MIO) specifies three main applications for AIS:(1) For ship to ship, information exchange to assist in collision avoidance.(2) For littoral states, to obtain information about ships and their cargoes.(3) As a VTS tool, to enhance shipping traffic management.In view of AIS can enhance VTS function and efficiency of shipping traffic management, the application of AIS to VTS becomes one of three main applications of AIS.In order to apply AIS to Yingkou VTS, on the basis of extensively referring to home and abroad materials, the paper goes into details on the development process and the international conventions and thetechnical standards and the working principle and the system form of AIS, systematically analyses the form and the working principle and the functions of Yingkou VTS, goes deep into the research for the relevant technology in the application of AIS to Yingkou VTS. The research results can not only be applied to Yingkou VTS, but also be applied to other harbor VTS.
