23、ECHNICAL COMMISSION _ MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS GLOBAL NAVIGATION SATELLITE SYSTEMS (GNSS) Part 1: Global positioning system (GPS) Receiver equipment Performance standards, methods of testing and required test results FOREWORD 1) The International Electrotechni
24、cal 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
25、end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, 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
26、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
27、 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)
28、 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
29、 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 th
30、e 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 equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they hav
31、e 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 whatso
32、ever, 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 publicat
33、ions 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 Standa
34、rd IEC 61108-1 has been prepared by IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems. This second edition cancels and replaces the first edition published in 1996. This edition of the IEC standard for GPS, compared to the previous edition, includes the fol
35、lowing technical changes: a) it reflects the changes brought about by IMO adopting GPS as part of the carriage requirement on ships defined in SOLAS Chapter V; b) the new IMO performance standard, resolution MSC.112(73), replaced the previous issue, A.819(19), for new installations on the 1st of Jul
36、y 2002. This second edition of IEC 61108- 1 incorporates revised tests for type approvals to the new performance standard; 4 61108-1 IEC:2003 c) changes include the need for a data output to the IEC 61162 series giving COG SOG and UTC with validity marking, operation during interference conditions a
37、nd improved failure warnings. This bilingual version (2013-01) corresponds to the monolingual English version, published in 2003-07. The text of this standard is based on the following documents: FDIS Report on voting 80/371/FDIS 80/373/RVD Full information on the voting for the approval of this sta
38、ndard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain uncha
39、nged until 2005. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its c
40、ontents. Users should therefore print this document using a colour printer. 61108-1 IEC:2003 5 MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS GLOBAL NAVIGATION SATELLITE SYSTEMS (GNSS) Part 1: Global positioning system (GPS) Receiver equipment Performance standards, methods of test
41、ing and required test results 1 Scope This part of IEC 61108 specifies the minimum performance standards, methods of testing and required test results for GPS shipborne receiver equipment, based on IMO Resolution MSC.112(73), which uses the signals from the United States of America, Department of De
42、fence (US DOD), Global Positioning System (GPS) in order to determine position. A description of the GPS SPS is given in the normative reference GPS, SPS signal specifi- cation USA Department of Defence 3rd Edition October 2001. This receiver standard applies to phases of the voyage “other waters“ a
43、s defined in IMO Resolution A.529(13). All text of this standard, whose meaning is identical to that in IMO Resolution MSC.112(73), is printed in italics and the Resolution and paragraph number indicated between brackets i.e. (M.112/A1.2). The requirements in clause 4 are cross-referenced to the tes
44、ts in clause 5 and vice versa. 2 Normative references The following referenced documents are indispensable for the application of this document.
