Maritime navigation and radiocommunication equipment and systems - Global navigation satellite systems (GNSS) - Part 3: Galileo - Receiver equipment - Performance requirements, methods of testing and required test results (IEC 61108-3:2010)

This part of IEC 61108 specifies the minimum performance standards, methods of testing and required test results for Galileo shipborne receiver equipment, based on IMO resolution MSC.233(82), which uses the signals from the Galileo Global 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 standard is different from IEC 60945, the requirement in this standard takes precedence. It 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. A description of the Galileo Open Service and Safety of Life Service is given in the Galileo interface control documents (see Bibliography). This receiver standard applies to navigation in ocean waters for the open service and harbour entrances, harbour approaches and coastal waters for the Safety of Life service, as defined in IMO resolution A.953(23). All text of this standard, whose meaning is identical to that in IMO resolution MSC.233(82), is printed in italics and the resolution and paragraph numbers are indicated in brackets i.e. (M.233/A1.2). The requirements in Clause 4 are cross-referenced to the tests in Clause 5 and vice versa.

Matériels et systèmes de navigation et de radiocommunication maritimes - Système mondial de navigation par satellite (GNSS) - Partie 3 : Equipement pour récepteur Galileo - Exigences d'exploitation et de fonctionnement, méthodes d'essai et résultats d'essai exigés (CEI 61108-3:2010)

L'IEC 61108-3:2010 spécifie les exigences minimales en matière de normes de fonctionnement, de méthodes d'essai et de résultats d'essai exigés pour le matériel de réception de bord Galileo, conformément à la résolution MSC.233(82) de l'OMI, et qui utilise les signaux provenant du système mondial de navigation par satellite Galileo afin de déterminer une position.
Elle prend en compte les exigences générales de la résolution   A.694(17) de l'OMI et est associée à l'IEC 60945. Lorsqu'une exigence de cette norme diverge de l'IEC 60945, c'est l'exigence de la présente Norme qui prévaut. Elle prend également en compte, selon le cas, les exigences de présentation des informations relatives à la navigation sur les écrans de navigation de bord explicitées dans la résolution MSC.191(79) de l'OMI et est associée à l'IEC 62288.

Ta del IEC 61108 na osnovi Resolucije IMO MSC.233(82) določa minimalne izvedbene standarde, metode preskušanja in pričakovane rezultate preskušanja za ladijsko opremo Galileo, ki za določanje položaja uporablja  signale globalnega navigacijskega satelitskega sistema Galileo. Upošteva splošne zahteve, navedene v Resoluciji IMO A.694(17), in se povezuje z IEC 60945. Kadar se zahteva v tem mednarodnem standardu razlikuje od IEC 60945, ima prednost zahteva v tem standardu. Po potrebi upošteva tudi zahteve za predstavitev informacij, povezanih z navigacijo, na ladijskih navigacijskih zaslonih, navedene v Resoluciji IMO A.694(79), in se povezuje z IEC 62288. Opis odprte storitve in storitve varovanja življenj Galileo je naveden v kontrolnih dokumentih vmesnika Galileo (glej bibliografijo). Ta standard za sprejemnik velja za navigacijo v oceanskih vodah za odprte storitve in vstope v pristanišča, približevanje pristaniščem in obalnim vodam za storitve varovanja življenj, kot opredeljuje Resolucija IMO A.953(23). Celotno besedilo tega standarda, ki je enako besedilu iz Resolucije IMO MSC.233(82), je tiskano poševno, v oklepajih pa so navedene številke Resolucije in njenih odstavkov, tj. (M.233/A1.2). Zahteve iz klavzule 4 se navzkrižno sklicujejo na preskuse v Klavzuli 5 in obratno.

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 61108-3 has been prepared by IEC technical committee 80:
Maritime navigation and radiocommunication equipment and systems.

Performance requirements, methods
of testing and required test results



1 Scope
This part of IEC 61108 specifies the minimum performance standards, methods of testing and
required test results for Galileo shipborne receiver equipment, based on IMO resolution
MSC.233(82), which uses the signals from the Galileo Global 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 standard
is different from IEC 60945, the requirement in this standard takes precedence. It 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.
A description of the Galileo Open Service and Safety of Life Service is given in the Galileo
interface control documents (see Bibliography). This receiver standard applies to navigation in
ocean waters for the open service and harbour entrances, harbour approaches and coastal
waters for the Safety of Life service, as defined in IMO resolution A.953(23).
All text of this standard, whose meaning is identical to that in IMO resolution MSC.233(82), is
printed in italics and the resolution and paragraph numbers are indicated in brackets i.e.
(M.233/A1.2).
The requirements in Clause 4 are cross-referenced to the tests in Clause 5 and vice versa.
