All port and coastal states must have an awareness of all vessels operating to and from their ports, as well as those transiting their coastal waters. This article describes Automatic Identification System (AIS). AIS integrates several different technologies, such as: the Global Navigation Satellite System, Differential Global Positioning System, frequency agile digital VHF transceivers, self-organizing communications protocols and an open system architecture which allows input from and output to other AIS receivers or external devices such as electronic chart displays or HF/SATCOM radios. The current implementation schedule requires AIS to be fitted aboard all ships of 300 gross tons and upwards engaged on international voyages, cargo ships of 500 gross tons and upwards not engaged on international voyages and passenger ships built on or after July 1, 2002. According to varying timetable, all ships required to be fitted with AIS must be fitted not later than July 1, 2008.
