On its 15th launch from the Guiana Space Centre (CSG), Soyuz launched two new Galileo satellites, the 13th and 14th in the constellation following the previous two launched last December. Ultimately, Galileo is set to give Europe an extremely precise, reliable and secure satellite navigation system.
Placed in a circular inclined orbit at an altitude of 23,522 kilometres, the two satellites—each weighing slightly over 700 kilograms—will deliver signals compatible and interoperable with existing satellite navigation systems, but one of Galileo’s key advantages is that it offers near-metric precision, and that is before signals are further refined by additional processing. The full Galileo constellation will comprise 26 satellites to provide unrivalled precision and serve an unprecedented range of applications. The 12 FOC satellites still to be deployed after this latest launch will be orbited by three Ariane 5 flights, each carrying four satellites.
On the occasion of this launch, Jean-Yves Le Gall, CNES President, ESA Co-Chair and interministerial coordinator for European satellite navigation programmes, commented: “CNES is especially proud to celebrate the orbiting of two new Galileo satellites after this second successful flight for Soyuz this year from the CSG. I would like to congratulate all of the partner teams working on this fundamental programme for Europe’s space policy: at the European Commission, ESA, Arianespace, Starsem, European and Russian manufacturers, at CNES and of course in particular the CSG, one of our four centres of excellence. This latest success marks another key milestone for Europe’s space programme, of which the Galileo system is one of the cornerstones.”
