Carried on MetOp-A, the SARR (Search and Rescue Repeater)receives and downlinks emergency signals from aircraft and ships in distress. In addition, it provides a downlink for data received by the SARP-3 (Search And Rescue Processor) also on board MetOp-A. The SARR receives distress beacon signals in three separate frequencies, translates and retransmits them to Local User Terminals on the ground. These terminals process the signals, determine the location of the beacons and then forward this information to a Rescue Mission Control Centre.
