Summary

1. Introduction
1.1 COSPAS-SARSAT is a joint international satellite-aided Search and Rescue (SAR) system. Over 40 countries and organisations contribute to the operation and management of the system.
1.2 At its 37th session in October 2006, the COSPAS-SARSAT Council reaffirmed its earlier decision (in conjunction with IMO & ICAO) taken at the 25th General Session (October 2000), that satellite processing of 121.5/243MHz transmissions would terminate on 1 February 2009.
1.3 From 1 February 2009, only 406MHz beacons will be processed within the COSPAS-SARSAT system. This affects all maritime beacons (EPIRBs), all aviation emergency locator transponders (ELTs) and all personal locator beacons (PLBs) operating on the 121.5/243MHz bands. Users should start taking steps to ensure they have an Initial Emergency Alerting Facility alternative. Suitable replacement would be the 406MHz beacon system.
2. Termination of 121.5/243 MHz Initial Emergency Alerting Facility in the GMDSS
2.1 121.5 / 243MHz beacons should not be used as an Initial Emergency Alerting device after 1 February 2009.
2.2 The primary method for electronic Initial Emergency Alerting will now be the 406MHz beacon system.
2.3 A 121.5 / 243MHz beacon may still be used as a homing device for suitably equipped SAR services, once an alert by other means has identified the vessel’s approximate position.
3. Disposal of Unwanted 121.5/243 MHz Beacons
3.1 The beacons in use are fitted with a Lithium battery. Batteries should be removed from unwanted beacons so that they can be disposed of in the correct manner, thus avoiding accidental activation; this can be carried out in various ways. The MCA encourages the following methods of disposal that comply with the Waste Electrical and Electronic Equipment (WEEE) Directive, Article 2.1:
