A beacon is a battery-powered emergency transmitter that sends a coded 406.1 MHz radio signal upon activation. Qaujimautik Systems sells both traditional beacons and those that are integrated with GPS to improve accuracy. There are a few types of beacons: Emergency Locator Transmitters (ELTs) for aviation use, Emergency Position Indicating Radio Beacons (EPIRBs) for maritime use, and Personal Locator Beacons (PLBs) for applications which are neither aviation or maritime.

The Anatomy of a Rescue

1. The activated PLB sends a digitally encoded signal indicating an emergency

2. An orbiting satellite receives the signal as it orbits the Earth

3. The satellite relays pertinent data to the ground station where the location of the PLB is computed

4. Location information is relayed to the Mission Control Centre (MCC) at CFB Trenton Ontario

5. The MCC conveys this information to the search and rescue point of contact in the province or territory where the PLB was activated

6. Local Search and Rescue Authorities respond to the emergency situation
