International Cospas-Sarsat Programme

The Cospas-Sarsat LEOSAR system provides global coverage for 406 MHz beacons.  Below is a list of the sites where LEOSAR local user terminals (LEOLUTS) are located.  Beacons that are activated in the areas shown in white on the map may have their transmissions detected and relayed to a LEOLUT for processing almost immediately, depending on the positions of overflying satellites.  Transmissions of beacons activated in the blue areas are stored when they are received by the satellite and later transmitted to a LEOLUT when the satellite passes near that ground station. (See the GEOSAR coverage map for the locations where beacon alert transmissions can be relayed immediately at all times by the GEOSAR satellites, provided that they are no terrain or other obstructions of the signal.)

Notes:
* = Dual system
** = Dual system, which operates as one LEOLUT
