Maritime navigation and radiocommunication equipment and systems - Automatic Identification System (AIS) - Part 1: AIS Base Stations - Minimum operational and performance requirements, methods of testing and required test results
This part of IEC 62320 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS Base Stations, compatible with the performance standards adopted by IMO Res. MSC.74 (69), Annex 3, Universal AIS. It incorporates the technical characteristics of non-shipborne, fixed station AIS equipment, included in recommendation ITU-R M.1371 and IALA Recommendation A-124. Where applicable, it also takes into account the ITU Radio Regulations. This standard takes into account other associated IEC international standards and existing national standards, as applicable. This standard is applicable for AIS Base Stations. It does not include specifications for the display of AIS data on shore.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote interna-
tional co-operation on all questions concerning standardization in the electrical and electronic fields. To this
end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Techni-
cal Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”).
Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject
dealt with may participate in this preparatory work. International, governmental and non-governmental organiza-
tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-
ganization for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all inter-
ested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinter-
pretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence be-
tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equip-
ment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and ex-
penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-
tions.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62320-1 has been prepared by IEC Technical Committee 80: Mari-
time navigation and radiocommunication equipment and systems.
The text of this standard is based on the following documents:

INTRODUCTION
Chapter V of the International Convention for the Safety of Life at Sea 1974 (SOLAS) requires
mandatory carriage of Automatic Identification System (AIS) equipment on all vessels con-
structed on or after 01 July 2002. Carriage for other types and sizes of SOLAS Convention
vessels was required to be completed not later than 31 December 2004.
SOLAS Chapter V, Regulation 19, clause 2.4.5 states that AIS shall:
1 provide automatically to appropriate equipped shore stations, other ships and aircraft in-
formation, 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, the IMO performance standards for AIS state that:
– 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 ac-
curate tracking. Transmission of the data should be with the minimum involvement of
ship's personnel and with a high level of availability.
The provision of Shore Based AIS will be necessary to attain the full benefit of the SOLAS
Convention requirements.
This part of IEC 62320 provides the minimum operational and performance requirements,
methods of test and the required test results for AIS Base Stations. The testing is divided into
three sections, the transceiver tests, the logical tests and the Presentation Interface tests.
These are captured in Clauses 8, 9 and 10 respectively. The method used for testing is that
the EUT should meet all the tests requirements of Clause 8 before proceeding to Clause 9.
Likewise, the unit should meet all of the test requirements before proceeding to Clause 10.
Clause 10 has also been prioritised so that the tests are progressive
Clauses 5 to 7 provide functional requirement information and Clause 8 provides the general
test environment for the EUT.

4 Functional layout of an AIS Base Station
4.1 General
The Base Station may be designed for dependent only operation or independent operation.
Both are under some control of the Physical Shore Station (PSS) as defined in the IALA Rec-
ommendation A-124.
---------------------- Page: 12 ----------------------
62320-1 © IEC:2007(E) – 9 –
– A dependent Base Station accesses the VHF data link (VDL) using only the combination of
linked TSA+VDM sentences (see Table 1), as provided by the PSS.
– An independent Base Station accesses the VDL using either the combination of linked
TSA+VDM sentences as provided by the PSS or by using internal control. When operated
as an independent Base Station the unit may be delegated certain autonomous functional-
ity under the supervisory control of the PSS.
The PSS, or external controlling entity, is responsible for Base Station configuration, trans-
mission scheduling, and processing of received information. Presentation Interface (PI) text
sentences are used to configure the Base Station, schedule message transmissions, and out-
put information.
When TSA and VDM sentences are used, the PSS is responsible for ensuring the integrity of
the VDL.
The tests in this standard are for all Base Stations. Additional tests for independent Base Sta-
tions are indicated by a note located at the beginning of each appropriate test section.

As a minimum, the following functional elements are required for the AIS Base Station:
• two multi-channel receivers;
• one multi-channel TDMA transmitter;
NOTE Since the minimum configuration of the AIS Base Station has only one transmitter, the AIS Base Sta-
tion cannot transmit on both AIS Channels (AIS A and AIS B) simultaneously.
• a controlling unit;
• an internal synchronisation source, which may also be used as a position sensor for inde-
pendent Base Stations. If used as a position source, the internal GNSS receiver shall
meet the appropriate requirements of IEC 61108-1;
• a Built-In-Integrity-Test unit (BIIT), which shall provide alarms;
