scope:

The present document sets out the minimum performance requirements and technical characteristics for satellite Personal Locator Beacon (PLB), operating in the COSPAS-SARSAT satellite system. This satellite PLB is primarily designed for use in maritime environment, however certain countries may licence them as land mobile satellite PLBs as well. The equipment covered by the present document operates in the 406,0 MHz to 406,1 MHz frequency band and is provided with a low power 121,5 MHz homing device. The present document also covers satellite PLBs with an integrated navigation device. Satellite PLBs designed and manufactured in accordance with the present document meet the satellite PLB requirements of the COSPAS-SARSAT System as well as relevant environmental requirements.
