The first switch-on of a Galileo search and rescue package shows it to be working well, according to the European Space Agency. Its activation begins a major expansion of the space-based Cospas–Sarsat network, which brings help to air and sea vessels in distress.
The second pair of Europe’s Galileo navigation satellites — launched together on October 12 last year— are the first of the constellation to host SAR search and rescue repeaters. These can pick up UHF signals from emergency beacons aboard ships and aircraft or carried by individuals, then pass them on to local authorities for rescue.
