46、r after 01 July 2002. Implementation for other types and sizes of SOLAS Convention vessels was required to be completed not later than 31 December 2004. SOLAS Chapter V, Regulation 19, section 2.4.5 states that AIS shall: a) provide automatically to appropriate equipped shore stations, other ships a
47、nd aircraft information, including ships identity, type, position, course, speed, navigational status and other safety-related information; b) receive automatically such information from similarly fitted ships; c) monitor and track ships; and d) exchange data with shore-based facilities. In addition
48、, the IMO Performance Standards for AIS states that: The AIS should improve the safety of navigation by assisting in the efficient navigation of ships, protection of the environment, and operation of Vessel Traffic Services (VTS), by satisfying the following functional requirements: 1) in a ship-to-
49、ship mode for collision avoidance; 2) as a means for littoral States to obtain information about a ship and its cargo; and 3) as a VTS tool, i. e. ship-to-shore (traffic management). The AIS should be capable of providing to ships and to competent authorities, information from the ship, automatically and with the required accuracy and frequency, to facilitate accurate
