406 Day: celebrating Galileo saving lives

Calling for help

Today is 406 Day – the annual campaigning day to spread awareness of the importance of emergency beacons, and the satellites that pick up their signals, including Europe’s Galileo constellation. As well as letting people across the world find their way, Galileo also serves to detect SOS messages and relay them to authorities, contributing to saving many lives.

He took to his life raft. As it hit the water it automatically activated his rescue beacon, transmitting a 406 MHz SOS signal for automatic pickup by participating satellites, courtesy of the Cospas-Sarsat satellite-based emergency detecting and locating system. The signal allowed the race authorities to localise Kevin’s position within a matter of minutes and send nearby boats to the rescue.

The only system that can independently locate a beacon anywhere on Earth’s surface, Cospas-Sarsat has helped save thousands of people since it was first established in 1982. Originally the system operated through transponders hosted aboard either low-Earth orbit or geostationary satellites.

In the last decade Galileo joined Cospas-Sarsat – supported by the European Commission, the system’s owner – driving a significant increase in performance. Because they have such a high orbital altitude, at 23 222 km up, while still moving steadily through the sky, Galileo satellites combine broad views of Earth with the ability to facilitate quick determination of the position of a distress signal through a combination of time-based and Doppler ranging.
