COSPAS-SARSAT is an intergovernmental humanitarian constellation of search and rescue satellites. It is a cooperative program of 45 nations that began in 1979 by Canada, France, the United States and the Soviet Union. COSPAS-SARSAT relays emergency location data, known as SAR (Search and Rescue) data, to authorities in each of the 45 signatory
EPIRB is the inclusion of a digitally encoded message, which may provide such information as the country of origin of the unit in distress, identification of the vessel or aircraft, nature of distress and, in addition, for satellite EPIRBs code in accordance with the maritime location protocol, the ship's position as determined by its
AIS -equipped EPIRBs and PLBs are now available in Australia. How does an AIS EPIRB or PLB work? AIS- equipped EPIRBs and PLBs transmit on 406 MHz, 121.5 MHz (the international aviation distress frequency and utilised for local homing by aircraft) and AIS. The HEX ID and position details are transmitted on 406 MHz.
EPIRBs and PLBs are radio transmitters. When activated in an emergency, they broadcast a 406 MHz signal via satellite to the Cospas-Sarsat global emergency network. Before the introduction of models that include GPS, your position was triangulated to within about two nautical miles and relayed to SAR (Search and Rescue) responders.
Finding your location. 1. EPIRB activates and transmits your beacon’s unique ID information or HEX ID to the closest satellite. 2. The satellite will access a registration database, which supplies information such as your GPS location, registration number of your vessel, and emergency contact information. 3.
