The SAR/Galileo service is Europe's contribution to the Cospas-Sarsat System. The Galileo satellites (except GSAT0101 and GSAT0102) are fitted with transparent repeater instruments (SARR) operating in the 1544 - 1545 MHz downlink band (L-band) capable to relay Cospas-Sarsat compliant 406 MHz distress signals without on board processing, data storage or demodulation, to any compatible Ground Segment worldwide.

The following table lists the active Galileo satellites contributing to the SAR/Galileo Forward Link Service (FLS) and the SAR/Galileo Return Link Service (RLS). For a detailed description of each field in this table please click here.

1: Galileo IOV satellites GSAT0101, GSAT0102 are not fitted with SARR payload.

2: Galileo satellite GSAT0104 is not used for the Galileo Open Service but the SARR is active and used in operations.

3: Galileo satellite GSAT0204 has been removed from OS service since 2017-12-08 until further notice for constellation management purposes (see NAGU 2017045). No orbit data will be provided on the broadcasted signals or through the Galileo SAR Server.
