We’re all familiar with Emergency Position Indication Radio Beacons (EPIRBs). Yachts venturing further than 2 NM off the coast are obliged to carry them on board. In addition, some of us may also carry Personal Locator Beacons (PLBs), attached to our life vests to help find us in a man overboard emergency.
Both EPIRBS and PLBs send a signal to overhead satellites to set off an alarm at the Rescue Authority, in Australia that is AMSA. While these beacons have a proven track record in saving hundreds of people in emergency situations, they still suffer from some limitations. For example, EPIRBs can only send an “all out” Mayday message, with no possibility of indicating the level of emergency, nor can rescue authorities acknowledge or establish return communications. PLBs will only send a mayday and position to the rescue authorities, rather than to those closest to the incident, usually surrounding vessels, who are in a position to provide immediate assistance.
