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. Galileo search and rescue repeater signal. Once the satellites reached their 23,222 km-altitude orbits, a rigorous test campaign began. The turn of the SAR repeater aboard the third Galileo satellite came on January 17. “At this stage, our main objective is to check the repeater has not been damaged by launch,” explained ESA’s Galileo SAR engineer Igor Stojkovic. “The first day was a matter of turning the repeater on and checking its temperature and power profiles were as predicted. The following day involved sending a signal to the repeater using the UHF antenna at ESA’s Redu Centre in Belgium, then picking up the reply from our L-band antenna.” Redu’s antenna is 20 meters in diameter, so the shape of the relayed signal was captured in great detail, out of all proportion to surrounding noise. “We can precisely measure its power, the time the relay took and so on,” added Igor. More detailed system testing will follow, to completely prove this new type of SAR payload in orbit. Cospas–Sarsat system. The international system has been in use for more than three decades, saving some 31,000 lives. Cospas is a Russian acronym for “Space System for the Search of Vessels in Distress,” with Cospas standing for “Search and Rescue Satellite-Aided Tracking.” Ground stations — known as Local User Terminals — pinpoint the source of distress calls using signals relayed by participating satellites, then alert local authorities. The GPS satellites will also provide a medium-Earth-orbit Sarsat capability and testing is underway. All nine Block IIR satellites carry experimental payloads and all IIF satellites are scheduled to.
