Kannad 1202394 XS-4 Personal Locator Beacon with GPS
The Cospas-Sarsat System is the only system to provide distress alerts and location data of 406 MHz beacons activated anywhere in the world.
The distress signal is relayed by the Cospas-Sarsat LEOSAR satellites to the ground stations (LUT) that calculate its position thanks to the Doppler Effect. With a built-in GPS, the GEOSAR satellites receive the signal and position within 5 minutes.
The Mission Control Center (MCCs) network processes the information and informs the nearest Rescue Coordination Center (RCC) so that SAR authorities can organize rescue operations.
