COSPAS/SARSAT SYSTEM

The COSPAS/SARSAT system utilises two satellite arrays to provide distress alert and
location data to search and rescue authorities:
• The GEOSAR system can provide near immediate
alerting within the coverage of the receiving satellite.
• The LEOSAR system provides coverage of the polar
region beyond the range of the GEOSAR system.
Local Users Terminals (LUTs) receive and process the satellite downlink signal to generate
the distress alerts. The distress alerts, generated by the LUTs, are then received by Mission
Control Centres (MCCs) which then forward the alert to Rescue Co-ordination Centres
(RCCs), Search and Rescue Points of Contacts (SPOCs) and other MCCs.
