Galileo satellite progress from Paris

Gaileo is turning out to be a hot topic at this year's Paris Air Show. On the 15th June ESA and Arianespace signed a contract for the launch of the first four operational Galileo satellites on two Soyuz launch vehicles from Europe’s Spaceport in French Guiana. Also this week, ESA and the OHB/SSTL consortium signed a contract for sourcing long-lead items for Galileo satellites. The Galileo In-Orbit Validation (IOV) Launch Services Contract covers the launch of the first four operational Galileo satellites using two Soyuz launch vehicles that will lift off from the Guiana Space Centre (Centre Spatial Guyanais "“ CSG), Europe’s Spaceport in French Guiana.

This new development follows the successful launch of the GIOVE-A satellite which was built by SSTL and the GIOVE-B satellite which was to be built by the European Satellite Navigation Industries satellite consortium and ultimately completed by Astrium. Both satellites have provided a great deal of data, for example helping with with clock characterisation, Galileo signal testing and in understanding the radiation that future Galileo satellites such as the new IOV satellites can expect in Medium Earth orbit (MEO). The signature of the IOV Launch Services Contract in Paris marks an important milestone for the Galileo programme as it progresses towards the operational deployment of the satellites of the Galileo satellite navigation system. The four IOV satellites will be placed in a circular orbit at an altitude of MEO of 23 600 km by the end of 2010. Development of the Galileo system is being carried out under a joint ESA/European Union programme. The launch vehicle chosen to carry the four Galileo IOV satellites into orbit is the Soyuz ST-B with a Fregat MT upper stage, which has been adapted for the deployment needs of the Galileo programme. The Soyuz at CSG Programme is an ESA Programme with co-funding of Arianespace and the European Union.

(SSTL) have signed a contract for sourcing long-lead items for satellites for the future European Galileo navigation system in Paris the same week. The EUR 10 million contract is carried out under a program initiated and funded by the European Union. Through this contract, OHB and SSTL are able to place orders for satellite technologies which require considerable lead times for development and sourcing ahead of the award of the actual contract for the construction of the satellites. The Galileo System customers, the European Union and the ESA, are thus ensuring that the schedule for implementation of Galileo can be maintained. OHB and SSTL are one of two consortia bidding for the development and con-struction of 28 satellites for Galileo. By allowing two consortia to build spacecraft for this significant undertaking, ESA is ensuring that the full operational capa-bility can be put in place as soon as possible and at best value to the EU. The system is to be fully operational by 2013 following full contract signature later in 2009.
