GPS Galileo finally on track
Posted by adminAfter years of uncertainty, Galileo, the European satellite navigation, has reached a milestone Wednesday with the signing at Paris Air Show, the last two industrial contracts awarded to Thales Alenia Space (281 million) and EADS-Astrium (73.5 million) for the realization of the "ground segment" of the device. Namely, a network of 21 stations to receive and rebroadcast the signal transmitted by satellites, distributed on the surface of the globe as well as two control centers based in Italy and Germany, "Now it remains to put satellites into orbit and build ground facilities.Galileo becomes a reality, "welcomed Jean-Jacques Dordain, the Director General of the European Space Agency that provides project management of this mammoth project on behalf of the European Union.
The first two satellites to be launched on October 20 at 24:00 (French time) from the Kourou space center, a Russian Soyuz rocket that will be the first launch from French Guiana. Another dual launch is scheduled for first half of 2012. Once the first four satellites positioned 20,000 km above the in-orbit validation phase (IOV), which is essential to test the operational capabilities of the system will begin.The signal they transmit back to Earth will allow users equipped with a suitable receiver to determine their position in real time, with an accuracy of one meter.
But to ensure comprehensive coverage of the territory, with this level of performance, both in cities (where buildings cause interference) in mountainous areas, Galileo must be supported, ultimately, a fleet of 30 satellites .
"At the rate of a dual launch every six months, we hope to place 24 satellites into orbit by the end of 2014," said Wednesday the European Commissioner for Industry, Antonio Tajani. A level at which Galileo will begin to be operational. The remaining six satellites will be purchased now through the "500 million euros of savings" on the project budget, said Mr. Tajani.Specifically, "the European Commission will request 1.4 billion instead of $ 1.9 billion for the next financial perspective (2014-2018)". An amount that will add 3.4 billion to the current fiscal year (2009-2013).
A market of 90 billion euros
This "good news" is undoubtedly to reassure policy makers on economic and technical and financial viability of a project that has accumulated delays since the launch of the first test satellite Giove-A in December 2005. In addition, it is clear that Galileo will be operational more quickly, more quickly in the European economy will reap the benefits.
The market for satellite navigation, today mainly occupied by the American GPS, is estimated at 90 billion euros for the period 2010-2030.
