The Complete Guide to AIS Automatic Identification System/Полное руководство по автоматической идентификационной системе AIS

Книга на английском языке
Radio exchanges like the above are a commonplace occurrence on ships at sea, especially in busy waterways. The weak link in the current generation of collision-avoidance electronics is the inability to identify any given radar target when multiple contacts are being tracked, especially at night or in reduced visibility, when it is impossible to verify a ships identity visually This inevitably leads to confusion, and has been cited as a contributing factor to many collisions and near-collisions at sea.
A new technology, called Automatic Identification Systems (AIS), will help to resolve this difficulty by providing a means for ships to exchange ID, position, course, speed and other vital data, with all other nearby ships and shore stations through a standardized transponder system. The data exchange will be totally automatic and transparent to die users. The result will be a dramatic improvement in situational awareness for officers of the watch, who will have a clear and unambiguous identification, as well as other vital information, from all other AlS-equipped ships.
AIS will have a far-reaching impact on safety at sea. It will be required on most ocean-going commercial ships, and will also be integrated into shoreside surveillance and vessel traffic control systems.
