French Guiana: Blastoff! Europe launches two more Galileo satellites

French Guiana, Kourou
March 27, 2015 at 21:10 GMT +00:00 · Published

A Russian Soyuz ST-B rocket launched the Galileo 7 and 8 satellites from Europe’s Spaceport in Kourou, French Guiana on Friday. Galileo is the European Space Agency's global navigation satellite system, which aims to provide an accurate, guaranteed, global positioning service for both private and civilian use. It is compatible with both the US’ GPS service and Russia’s global satellite navigation systems.

By using the frequencies of two satellites at once, Galileo will deliver real-time positional accuracy down to the range of one metre (3.2 feet). It's services will assist with transport infrastructure, providing navigational support for cars, ships and airplanes. Another feature will be Galileo’s search and rescue function, which will see the satellites equipped with a transponder that can transfer distress signals from individual user’s transmitters to regional search and rescue coordination centres.

Once fully deployed, Galileo will consist of 30 satellites, 27 of which will be operational with three in reserve, which will be located in Medium Earth Orbit at approximately 23,322 kilometres (14,491.6 miles) above the Earth’s surface. The seventh and eighth satellites will join the six currently in orbit, with Galileo 9, 10, 11 and 12 scheduled for launch later in 2015.
