AIS |
Automatic Identification System |
|
|
SOLAS Chapter V, Regulation 19, section 2.4.5 states that: |
"AIS shall:-
provide automatically to appropriate equipped shore stations,
ships information including:-
ship's
identity, type, position, course, speed, navigational status,
and other safety-related information; |
receive automatically such information from similarly fitted ships;
monitor and track ships; and
exchange data with shore-based facilities." |
In addition, the IMO
Performance Standards for AIS state:- |
"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-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 tracking.
Transmission of the data should be with the minimum involvement of
ship's personnel and with
a high level of availability.” |
