Emergency Position-Indicating Radio Beacons (EPIRBs)


An EPIRB is an Emergency Position-Indicating Radio Beacon, a compact, buoyant, self-contained radio transmitter. Activated , it continuously emits a distinctive radio signal for a minimum of 48 hours.

The COSPAS-SARSAT satellite system

Under the COSPAS-SARSAT international satellite-aided tracking system, polar-orbiting satellites are able to detect distress signals from satellite-compatible radio beacons when the beacons are activated.

As the satellites pass overhead, signals are deteced and relayed back to the Rescue Coordination Centre (RCC) in Canberra through ground receiver stations located at Albany, WA, Bundaberg, QLD and Wellington, New Zealand.

The location of the boat or aircraft in trouble can be pinpointed to within about 20 km and often within one or two hours.

121.5/243 Mhz EPIRBS (satellite compatible)

The new 121.5/243 Mhz EPIRBs provide greater certainty of detection and location accuracy.

406Mhz EPIRBs

The more advanced 406 Mhz EPIRBs can indicate positions to within six kilometres and can relay much more information than simply the distress location. For example it can be programmed to tell the RCC the registration of the aircraft or ship which i n turn can indicate the type of craft, survival gear carried and the number of people on board.
