EPIRBs are the maritime specific beacon which sends a 406 MHz signal to satellites orbiting the earth. Other beacons do also communicate with the satellites in the same way. ELTs (Emergency Locator Transmitters) and PLBs (Personal Locator Beacons) are two such examples. ELTs are designed for use in aviation, and PLBs are for personal use. Can distress beacons be registered for more than one use? AMSA can register a beacon for up to four uses e.g. vessel, vehicle, aircraft. However, please note that in some cases PLBs cannot be carried as a substitute to an EPIRB. We’ve continued to ensure our maritime safety services go above and beyond the IMO’s Safety of Life at Sea (SOLAS) and Global Maritime Distress and Safety System (GMDSS) requirements – by, for example, exceeding the demand for satellite and ground network availability of 99.9 percent. Today, over our L-band network, we support both SOLAS Vessels trading exclusively in sea area A1 may fit a VHF DSC EPIRB in lieu of a 406 MHz EPIRB). Passenger ships. Every passenger ship shall be provided with means of two way on scene radiocommunications for search and rescue purposes using the aeronautical frequencies 121.5 MHz and 123.1 MHz from the position from which the ship is normally .
