5.8 RLS (Return Link Service)
As part of the Cospas-Sarsat System, Galileo satellites are capable of picking up emergency
signals emitted on 406 MHz by distress beacons, and transmitting a signal back to the beacon
via the E1 frequency to confirm receipt of the distress signal. This technology has been
developed under the international Cospas-Sarsat program. It comprises the Galileo-enabled dis
tress beacons, the SAR payload on the Galileo satellites, as well as ground-based receiving sta
tions (LUTs) and Mission Control Centers.
If the option "Galileo" (Opt-GAL) is installed, GSG is capable of simulating the Return Link Mes
sage (RLM) transmitted by the Galileo signal to the distress beacon.
