9、tyNET Manual was first produced in 1994. The second edition was published in 2003 containing amendments endorsed by the Maritime Safety Committee at its seventy-sixth session in December 2002 by MSC/Circ.1064.At its seventh meeting in September 2005, the IHOs Commission on the Promulgation of Radio

10、Navigational Warnings (CPRNW*) established a Working Group to review all World-Wide Navigational Warning Service (WWNWS) documentation. The Working Group included representation from the WMO and prepared at first, revisions to IMO resolutions A.705(17), “Promulgation of Maritime Safety Information”

11、and A.706(17), “World-Wide Navigational Warning Service”. The proposed revisions of the resolutions were circulated to IHO Member States under IHB CL 104/2007, endorsed by COMSAR at its twelfth session in April 2008 and subsequently approved by the Maritime Safety Committee at its eighty-fifth sessi

12、on in November/December 2008 by MSC.1/Circ.1287 and MSC.1/Circ.1288 respectively.The IHO CPRNW*Working Group then prepared the revised Joint IMO/IHO/WMO Manual on Maritime Safety Information incorporating the revised information from resolutions A.705(17), as amended and A.706(17), as amended. The r

13、evised text of the Joint IMO/IHO/WMO Manual on Maritime Safety Information was circulated to IHO Member States under cover of IHB CL 70/2008, endorsed by COMSAR at its thirteenth session in January 2009 and subsequently approved by the Maritime Safety Committee at its eighty-sixth session in May/Jun

14、e 2009 by MSC.1/Circ.1310.*CPRNW was renamed the IHO WWNWS Sub-Committee (WWNWS) with effect from 1 January 2009.International SafetyNET Manual2Continuing with the holistic approach of reviewing all the MSI documents from the top-down, the IHO WWNWS Working Group prepared the third revision of the I

15、nternational SafetyNET Manual. The revised text of the International SafetyNET Manual was circulated to IHO Member States under cover of IHB CL 68/2009, endorsed by COMSAR at its fourteenth session in March 2010 and subsequently approved by the Maritime Safety Committee at its eighty-seventh session

16、 in May 2010 by MSC.1/Circ.1364 and will come into force on 1 January 2012.31 General informationSafetyNET is an international automatic direct-printing satellite-based service for the promulgation of Maritime Safety Information (MSI), navigational and meteorological warnings, meteorological forecas

17、ts, Search and Rescue (SAR) information and other urgent safety-related messages to ships. It has been developed as a safety service of the Inmarsat-C Enhanced Group Call (EGC) system to provide a simple and automated means of receiving MSI on board ships at sea. The message-selection features of Sa

18、fetyNET receivers enable mariners to receive safety information broadcasts that are tailored to their particular needs.SafetyNET fulfils an integral role in the Global Maritime Distress and Safety System (GMDSS) developed by the International Maritime Organization (IMO) and incorporated into the 198

19、8 amendments to the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, as a requirement for ships to which the Convention applies.This Manual describes the structure and operation of the International SafetyNET Service. It is intended primarily for national Administrat

20、ions and registered information providers, but may also be useful to the mariner who requires more operational information than is found in manufacturers equipment manuals.2 SafetyNET service2.1 Introduction2.1.1 SafetyNET provides shipping with navigational and meteorological warnings, meteorologic

21、al forecasts, shore-to-ship distress alerts, SAR infor-mation and other urgent information in accordance with the requirements of the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended. It is suitable for use in all sizes and types of ships. Figure 1 illustrates the way

22、 the service is structured.2.1.2 SafetyNET is a service of Inmarsats EGC system and was specifically designed for promulgation of MSI as a part of the GMDSS. The EGC system (technically a part of the Inmarsat-C system) provides an automatic method of broadcasting messages to both fixed and variable

23、geographical areas. It is designed with the capability to provide services within the coverage areas of geostationary satellites, known as satellite ocean regions (approximately between 76nullN and 76nullS). In addition to providing services to ships operating International SafetyNET Manual4in sea a

24、rea A3, it also provides the means of disseminating MSI to coastal warning areas not covered by the International NAVTEX service.NavigationalwarningMeteorological informationSAR informationOther urgent safety-related informationMARITIME SAFETY INFORMATION (international and national co-ordination)IN

29、 Satellite ocean regionFigure 2 Basic concept of the Inmarsat Enhanced Group Call system2.1.3 SafetyNET offers the ability to direct a message to a given geographical area. The area may be fixed, as in the case of a NAVAREA/METAREA or coastal warning area; or it may be a user defined area (circular

30、or rectangu-lar). A user defined area is used for messages, such as a local storm warning or a shore-to-ship distress alert, for which it is inappropriate to alert ships in an entire satellite ocean region or NAVAREA/METAREA. The general EGC system capabilities are shown in figure 2.2.1.4 SafetyNET

31、messages are submitted by registered information providers for broadcast to the appropriate satellite ocean region(s) via an Inmarsat-C Land Earth Station (LES). Messages are broadcast according to their prior-ity, i.e. distress, urgency or safety. Aboard ship, messages are received by type-approved

32、 Inmarsat-C or Mini-C mobile terminals with EGC SafetyNET capability.2.2 Definitions2.2.1 For the purposes of this manual, the following definitions apply:.1 Coastal warning means a navigational warning promulgated as part of a numbered series by a National co-ordinator. Broadcast shall be made by t
