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 international
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, Technical 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 organizations liaising
with the IEC also participate in this preparation. 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 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 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
misinterpretation 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 between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
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 61108-5 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems.
The text of this International Standard is based on the following documents:
FDIS Report on voting
80/952/FDIS 80/955/RVD

Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

Part 5: BeiDou navigation satellite system (BDS) – Receiver equipment –
Performance requirements, methods of testing and required test results



1 Scope
This part of IEC 61108 specifies the minimum performance requirements, methods of testing
and required test results for BDS shipborne receiver equipment, based on IMO resolution
MSC.379(93), which uses the signals from the BeiDou navigation satellite system in order to
determine position. It takes account of the general requirements given in IMO resolution
A.694(17) and is associated with IEC 60945. When a requirement in this document is different
from IEC 60945, the requirement in this document takes precedence. This document also takes
account, as appropriate, of requirements for the presentation of navigation-related information
on shipborne navigational displays given in IMO resolution MSC.191(79) and is associated with
IEC 62288 and MSC.302(87) associated with IEC 62923-1.
This receiver standard applies to navigation in the ocean, coastal, harbour entrances, harbour
approaches and restricted waters, as defined in IMO resolution A.915(22) and IMO resolution
A.1046(27).
