What is IMO performance standard requirement for AIS?

According to Chapter V, Regulation 19, section 2.4.5

“AIS shall

1. Provide automatically to appropriate equipped shore stations, other ships and aircraft information, including ship’s identity, type, position, course, speed, navigational status and other safety-related information;
2. Receive automatically such information from similarly fitted ships;
3. Monitor and track ships; and
4. Exchange data with shore-based facilities.

In addition to above, the IMO Performance Standards for AIS state: “

1.  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:
2.  In a ship-to-ship mode for collision avoidance;
3.  As a means for littoral States to obtain information about a ship and its cargo; and
4.  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.”
