15、erformance requirements, methods of testing and required test results FOREWORD 1) The IEC (International Electrotechnical Commission) is a world wide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote in
16、ternational 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 t
17、he 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 con
18、ditions 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 Na
19、tional 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 u
20、nification, 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 latt
21、er. 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 p
22、atent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61097-13 has been prepared by IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems. The text of this standard is based on the followin
23、g documents: FDIS Report on voting 80/358/FDIS 80/370/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 2. The committee has decided
24、 that the contents of this publication will remain unchanged until 2008-01. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 4 61097-13 IEC:2003(E) GLOBAL MARITIME DISTRESS AND SAFETY SYSTEM (GMDSS) Part 13: INMARSAT F77 ship earth station equi
25、pment Operational and performance requirements, methods of testing and required test results 1 Scope This part of IEC 61097 specifies the minimum operational and performance requirements, technical characteristics, methods of testing and required test results for INMARSAT F77 ship earth stations (SE
26、S), capable of transmitting and receiving distress and safety communications, initiating and receiving distress priority calls and transmitting and receiving general radiocommunications, using radiotelephony (voice), as required within Regulation IV/10.1 and 14.1 of the 1988 amendments to the 1974 I
27、nternational Convention for the Safety of Life at Sea (SOLAS), for use in the GMDSS. The INMARSAT F77 is intended to meet the voice requirements of IMO Resolution A.888(21). In order to meet the GMDSS carriage requirements of SOLAS in respect of receipt of SafetyNET broadcasts and direct printing te
28、legraphy, it is necessary to install a combined INMARSAT C/EGC transceiver in addition to the INMARSAT F77 equipment. Annex B provides more information. Since Class 1 INMARSAT A and B ship earth stations meet the data requirement of GMDSS, although not necessarily those of MSC.130(75), the F77 canno
29、t necessarily be considered as a direct replacement for these ship earth stations. This standard also takes into account the priority access (voice pre-emption) requirements of IMO Resolution A.888(21). This standard takes account of IMO Resolution A.694(17) to which is associated IEC 60945. When a
30、requirement in this standard is different from IEC 60945, the requirement in this standard shall take precedence. This standard incorporates the performance standards of IMO Resolution MSC.130(75) and the clarifications of certain requirements in IMO performance standards for GMDSS Equipment defined
31、 in IMO MSC Circular 862. It also incorporates the relevant ITU Radio Regulations. All text of this standard, whose wording is identical to that in the IMO SOLAS Convention 1974 as amended, IMO Resolutions and IMO MSC Circular 862, is printed in italics and the Resolution or Recommendation and parag
32、raph number indicated between brackets. It is a requirement of INMARSAT Ltd that all INMARSAT F77 mobile earth station models be type-approved by INMARSAT before they can be allowed access to the INMARSAT space segment. This testing is designed to demonstrate that the equipment under test will be co
33、mpatible with the INMARSAT F77 system and will not cause interference to other satellite users. It is recommended that approval authorities accept testing organized and supervised by INMARSAT, which results in INMARSAT type approval, without additional testing other than that defined in this standar
34、d. It is also recommended that equipment manufacturers rationalize the test requirements of this standard and those of INMARSAT before embarking on the approval process. NOTE This standard does not incorporate the INMARSAT system requirements needed for INMARSAT type approval. For these, the latest
35、edition of “INMARSAT mini-M SDM Change Note No. 65” should be consulted. When a requirement in this standard is different from one in the above-mentioned INMARSAT document, reference shall be made to the most recent IMO and ITU applicable documents to resolve the difficulty.61097-13 IEC:2003(E) 5 2
