Emergency Beacons

Category Description:

Emergency Survival Beacons are critical in the chain of survival when an emergency at sea occurs.

The search & rescue process:

1. Distressed mariner/outdoor adventurer/pilot activates beacon (EPIRB, PLB, ELT).

2. Beacon transmits a 406 MHz emergency message containing your Unique Identifier Number (UIN) to the LEOSAR (polar orbiting) and GEOSAR* (geostationary) satellite systems.

3. The satellites relay the 406 MHz emergency message to a ground station called the Local User Terminal (LUT). The LUT calculates the location of the signal by measuring the Doppler shift caused by the relative movement between the satellite and the beacon and forwards the location to the Mission Control Center (MCC).

4. The MCC continues to receive information from additional satellite passes and further refines the beacon position (2.3 nm search radius). An alert message is generated that is combined with the registration information from the database and is forwarded to the appropriate Rescue Coordination Center (RCC).

5. The RCC makes contact with the persons listed in the database to verify the existence of an emergency and gathers additional information about the beacon users. The RCC will dispatch the closest, capable Search and Rescue (SAR) forces.

6. Local SAR forces launch a rescue mission and use the 121.5 MHz homing signal to pinpoint the beacon. Information provided by ACR Electronics Inc.
