9、position-indicating radio beacon (satellite EPIRB) system operating through a satellite system in the 406 MHz band (1986-1990-2000-2004-2010) Scope This Recommendation provides transmission characteristics of a satellite emergency position-indicating radio beacon system (satellite EPIRBs) operating
10、in the 406 MHz band. The ITU Radiocommunication Assembly, considering a) that satellite EPIRBs can be used for distress alerting in the maritime, land and aeronautical environments; b) that satellite EPIRBs with common characteristics may be employed in diverse operating environments; c) that satell
11、ite EPIRBs are one of the prime alerting means in the Global Maritime Distress and Safety System (GMDSS) of the International Maritime Organization (IMO); d) that all ships to which Chapter IV of the International Convention for the Safety of Life at Sea (SOLAS), 1974, (as amended in 1988) applies,
12、are required by Regulation IV/7.1.6 to carry a satellite EPIRB from 1 August 1993; e) that SOLAS Regulation IV/7.1.6 provides for the carriage of a satellite EPIRB operating in the 406 MHz band; f) that all aeroplanes and helicopters for which Parts I, II and III of Annex 6 of the Convention on Inte
13、rnational Civil Aviation apply, are required to carry at least one satellite EPIRB operating in the 406 MHz band (referred to as Emergency Locator Transmitter (ELT) in the ICAO documentation), noting a) the current and planned availability of operational Cospas-Sarsat satellites in orbit; b) the cur
14、rent and projected availability of the Cospas-Sarsat ground system, *This Recommendation should be brought to the attention of the International Maritime Organization (IMO), the International Civil Aviation Organization (ICAO), the International Mobile Satellite Organization (IMSO) and the Cospas-Sa
15、rsat Secretariat. 2 Rec. ITU-R M.633-4 recommends 1 that the transmission characteristics and data formats for a satellite EPIRB operating through a satellite system in the 406 MHz band should be in accordance with Cospas-Sarsat Document C/S T.001 (Issue 3, Revision 10, October 2009 titled Specification for 406 MHz Cospas-Sarsat Distress Beacons). NOTE 1 A copy of document C/S T.001 (Issue 3, Revision 10, October 2009) can be obtained free of charge from the Cospas-Sarsat Secretariat (mailcospas.sarsat.int) or the Cospas-Sarsat website (http:/www.cospas-sarsat.org/).
