dentification System (AI S) equipment on all vessels constructed on or after 01 Jul y 2002 I mplem entation for other types and sizes of SOLAS Convention vessels was required to be com pleted not later than 31 December 2004 SOLAS Chapter V, Regulation 9, section states that AI S shall: a) provide automaticall y to appropriate equipped shore stations, other ships and aircraft inform ation, including ship's identity, type, position, course, speed, navigational status and other safety-related information; b) receive autom atically such inform ation from similarl y fitted ships; c) monitor and track ships; and d) exchange data with shore-based facilities I n addition, the I MO Perform ance Standards for AI S states that: • The AI S should improve the safety of navigation by assisting in the efficient navigation of • ships, protection of the environm ent, and operation of Vessel Traffic Services (VTS), by satisfying the following functional requirem ents: ) in a ship-to-ship m ode for collision avoidance; 2) as a m eans for littoral States to obtain inform ation about a ship and its cargo; and 3) as a VTS tool, i e ship-to-shore (traffic managem ent) The AI S should be capable of providing to ships and to competent authorities, information from the ship, automaticall y and with the required accuracy and frequency, to facilitate accurate tracking Transmission of the data should be with the m inim um involvem ent of ship's personnel and with a high level of availability The provision of Shore Based AI S will be necessary to attain the full benefit of the SOLAS Convention requirements This standard provides the minimum operational and perform ance requirements, methods of test and the required test results for AI S repeater stations The testing is divided into two
