MSC.74(69) Annex 3
RECOMMENDATION ON PERFORMANCE STANDARDS FOR AN UNIVERSAL SHIPBORNE AUTOMATIC IDENTIFICATION SYSTEM(AIS)
1 Scope
1.1 These performance standards specify the requirements for the universal AIS.
1.2 The AIS should improve the safety of navigation by assisting in the efficient navigation of ships, protection of the enviroment, 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).
1.3 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.
1.4 The installation, in addition to meeting the requirements of the Radio Regulations, applicable ITU-R Recommendations and the general requirements as set out in resolution A.694 (17), should comply with the following performance standards.
2 Functionality
2.1 The system should be capable of operating in a number of modes: .1 an “autonomous and continuous” mode for operation in all areas. This mode should be capable of being switched to/from one of the following alternate modes by a competent authority; .2 an “assigned” mode for operation in an area subject to a competent authority responsible for traffic monitoring such that the data transmission interval and/or time slots may be set remotely by that authority; and .3 a “polling” or controlled mode where the data transfer occurs in response to interrogation from a ship or competent authority. RESOLUTION MSC.74(69) (adopted on 12 May 1998) ADOPTION OF NEW AND AMENDED PERFORMANCE STANDARDS MSC 69/22/Add.1 ANNEX 12 Page 14 I:\MSC\69\22-A1.WPD
3 Capability
3.1 The AIS should comprise: .1 a communication processor, capable of operating over a range of maritime frequencies, with an appropriate channel selecting and switching method, in support of both short and long range applications; .2 a means of processing data from an electronic position-fixing system which provides a resolution of one ten thousandth of a minute of arc and uses the WGS-84 datum.; .3 a means to automatically input data from other sensors meeting the provisions as specified in paragraph 6.2; .4 a means to input and retrieve data manually; .5 a means of error checking the transmitted and received data; and .6 built in test equipment (BITE). 3.2 The AIS should be capable of: .1 providing information automatically and continuously to a competent authority and other ships, without involvement of ship’s personnel; .2 receiving and processing information from other sources, including that from a competent authority and from other ships; .3 responding to high priority and safety related calls with a minimum of delay; and .4 providing positional and manoeuvring information at a data rate adequate to facilitate accurate tracking by a competent authority and other ships.
