FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. 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 organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the 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 interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61993-2 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems.
The text of this standard is based on the following documents:
FDIS Report on voting
80/315/FDIS 80/328/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged until
2006-07. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
Following the adoption by the International Maritime Organisation (IMO) of Resolution
MSC.74(69) Annex 3, Performance Standard for a Universal Shipborne Automatic Identifica-
tion System, TC 80 established Working Group 8A to develop IEC 61993-2. Technical
requirements were provided in ITU-R M.1371 "Technical characteristics for a universal
shipborne Automatic Identification System (AIS) using TDMA (Self-Organising Time Division
Multiple Access) in the VHF maritime mobile band". Carriage requirements for SOLAS ships
have been adopted by IMO for entry into force starting on July 1st 2002.
It was brought to the attention of WG8A that patents and patents pending pertaining to AIS
have been made freely available. TC 80 WG8A considers the technical implementation
specified by this International Standard to be in full accordance with the requirements of
Recommendation ITU-R M.1371-1 and as such to be free from claims of intellectual property
rights.
The provision of a high-speed network connection IEC 61162-3 is optional. It may become a
requirement in a later revision of this standard, when the relevant standard (IEC 61162-3) has
been adopted.
The IMO Resolution MSC.74(69) Annex 3, Performance Standard for an Universal Shipborne
Automatic Identification System, requires that the AIS has a means of processing data from
an electronic position fixing system that provides a resolution of one ten-thousandth of a
minute of arc and uses the WGS 84 datum. Resolution A.815(19) requires an accuracy of
position information better than 10 m in confined waters. This does not require but implies
that if the ship is not equipped with a DGNSS, the GNSS sensor internal to the AIS should be
a DGNSS and should be used as source of position information.
Moreover, Resolution MSC.74(69) Annex 3 does not include any requirement for backup
arrangements of the position information. However, a GNSS sensor is included in the AIS
equipment as the source of UTC. It is felt by IEC TC 80 that this GNSS sensor also can be
used as a back-up arrangement for the position information obtained from the ships DGNSS.
This would ensure the availability of the AIS system in case of failure of the ship’s EPFS.
Therefore, IEC TC 80 strongly recommends that manufacturers of AIS equipment implement
such an arrangement in accordance with table 4 of this International Standard.
Note that an IEC standard detailing class B AIS is being prepared as IEC 62287.

1 Scope
This International Standard specifies the minimum operational and performance requirements,
methods of testing and required test results conforming to performance standards adopted by
the IMO in resolution MSC.74(69), Annex 3, Universal Shipborne Automatic Identification
System. This standard incorporates the technical characteristics of Class A shipborne
equipment included in Recommendation ITU-R M1371-1 and takes into account the ITU Radio
Regulations where applicable. In addition it takes account of IMO resolution A.694(17) to
which IEC 60945 is associated.
This International Standard also specifies the minimum requirements both for the means to
input and display data and for the interfaces to other equipment suitable to be used as means
of input and display data.
NOTE All text of this standard, that is identical to that in IMO resolution MSC.74(69), Annex 3 and IMO resolution
