Part 2: Class A shipborne equipment of the universal automatic identification system (AIS) — Operational and performance requirements, methods of test and required test results.
(A3/1.2) The AIS shall 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:
• in a ship-to-ship mode for collision avoidance:
• as a means for littoral States to obtain information about a ship and its cargo: and
• as a VTS tool, i.e. ship-to-shore (traffic management).
4.1.3 Capabilities of the AIS
(A3/1.3) The AIS shall 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 shall be with the minimum involvement of ship’s personnel and with a high level of availability.
4.1.4 Additional requirements
(A3/1.4) 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). shall comply with the following performance standards, as contained in the following clauses.
4.1.5 Transmitter shutdown procedure
(M.1371/A2-2.13) An automatic transmitter hardware shutdown procedure and indication shall be provided in case a transmitter continues to transmit for more than 2 s. This shutdown procedure shall be independent of software control.
41.6 Quality assurance
The Administration shall require that the manufacturers have a quality control system audited by a competent authority to ensure continuous compliance with the type approval conditions. Alternatively, the Administration may use final product verification procedures where a competent authority verifies compliance with the type approval certificate before the product is installed on board ships.
NOTE The ISO 9000 series, as applicable, meets this requirement.
4.2 Modes of operation
(A3/2.1) The system shall be capable of operating in a number of modes:
1) an “autonomous and continuousTM mode for operation in all areas. This mode shall be capable of being switched to/from one of the following alternate modes by a competent authority;
The AIS shall be tested for compliance with the environmental, power supply, special-purpose and safety requirements of MO A.694(17) as detailed in IEC 60945. The required tests, for which a repeatable method of measurement has been defined, are given in Clauses 11, 12 and 13 of this standard. The declaration of category to IEC 60945:2002 Clause 4. shall define the relevant tests to be applied as follows:
• AIS equipment declared for protected installation shall meet the requirements described in Table 3 column “protected” of IEC 60945:2002:
• exposed AIS equipment shall meet the requirements described in Table 3 column “exposed” of IEC 60945:2002:
• portable AIS equipment shall meet the requirements of Table 3 of IEC 60945:2002 “protected” or “exposed” as appropriate.
5.2 Display of information
The AIS shall be tested as applicable against the requirements for presentation of information
contained in IEC 62288 (see 14.7.9).
6 Performance requirements
6.1 Composition
(A3/3.1) The AIS shall comprise (see Annex A):
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 (VHF) and long (beyond VHF) range applications. For long-range applications the AIS shall provide a two-way interface (see 7.6.4):
2) at least one transmitter, two TDMA receiving processes and one dedicated continuous DSC receiving process tuned to channel 70:
3) 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.
An interface (see 7.6.2) shall be provided to input the position used for navigation. Position information, if available from other EPFS, shall be used only as a back up and the user shall be informed of this (see 6.10).
4) a means to automatically input data from other sensors meeting the provisions as specified in 6.5.1 point 2); a means, external to the AIS, to comply with this requirement shall be tested to the applicable requirements of IEC 60945.
5) a means to input and retrieve data manually. The possibility of manual input and retrieval as described in 6.11 shall be demonstrated based on the manufacturer’s documentation.
6) a means of error checking the transmitted and received data (see Clause 7); and.BS EN 61993-2-2013 pdf download.
