Radio Equipment and Systems (RES); Float-Free Maritime Satellite Emergency Position Indicating Radio Beacons (EPIRBs) Operating on 406@025 MHz; Technical Characteristics and Methods of Measurement (Second Edition)
This ETS sets out the minimum performance requirements and technical characteristics for float-free satellite Emergency Position-Indicating Radio Beacons (EPIRB)@ operating in the COSPAS-SARSAT satellite system@ concerning radio communications for the Global Maritime Distress and Safety System (GMDSS). The equipment covered by this ETS operates on 406 MHz which is provided with a low power 121@5 MHz homing device. This ETS incorporates the relevant requirements of the International Telecommunications Union (ITU) and the International Maritime Organisation (IMO). This ETS is applicable for satellite EPIRBs operating over the temperature ranges of : - -40??to +55??(Class 1); or - -20??to +55??(Class 2); with a float free release mechanism. NOTE 1: The Class 2 equipment meets the IMO requirements of chapter IV@ regulations 7.1.6 and 14.1 of the 1988 amendments to the 1974 International Convention for Safety of Life at Sea (SOLAS) [2]. NOTE 2: The requirements for non float free satellite EPIRBs can be found in annex A.
