The COSPAS-SARSAT Search & Rescue System

1) Distressed mariner/outdoor adventurer
    activates EPIRB or PLB-EPIRB.

COSPAS-SARSAT Search and Rescue System
2) Beacon transmits a 406 MHz emergency message containing your Unique Identifier Number (UIN) to the LEOSTAR (polar orbiting) and GEOSTAR* (geostationary) satellite systems.
COSPAS-SARSAT Search and Rescue System
- 406 MHz Distress Signal 
  (2.3 nm accuracy 60 min. worldwide avg.)
- 406 MHz Distress Signal w/GPS
  (0.05 nm accuracy 15 min. worldwide avg.

3) The satellite relays 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.
Air-Sea has the latest
in signal testing equipment and can even signal test your beacon on board your vessel.
