| The European Commission has issued a contract worth some 255m euros (£210m; $330m) to a German-UK consortium to provide eight more spacecraft for its Galileo satellite-navigation network. | |
| It takes the number of spacecraft now in production at OHB System of Bremen and SSTL of Guildford to 22. | It takes the number of spacecraft now in production at OHB System of Bremen and SSTL of Guildford to 22. |

| To get the order, OHB System and SSTL had to beat off competition from Europe's biggest space company, Astrium. The consortium's win follows its initial contract victory in 2010 for 14 operational satellites. | |
| The EC is investing billions in its sat-nav project. It believes Galileo will bring significant returns to EU-bloc economies in the form of new businesses that can exploit precise timing and location data delivered from orbit. | The EC is investing billions in its sat-nav project.

| GPS already underpins a great swathe of activity with many uses that are unseen and unsung, such as the timing signal's widespread role in synchronising telecommunications systems and major financial transactions. | GPS already underpins a great swathe of activity with many uses that are unseen and unsung, such as the timing signal's widespread role in synchronising telecommunications systems and major financial transactions. |
| Galileo, once complete, is likely to have 30 satellites in orbit - but securing the last few will require another round of procurement by the EC. | Galileo, once complete, is likely to have 30 satellites in orbit - but securing the last few will require another round of procurement by the EC. |
| Its first two spacecraft, launched in October, were developed by Astrium. These are "pathfinder" units which, together with another pair due for launch later this year, will prove the Galileo system works end-to-end - from the satellites in the sky to the complex control systems on the ground. | Its first two spacecraft, launched in October, were developed by Astrium.

| A contract to launch the bulk of the initial 14 OHB-SSTL satellites has already been placed with French firm Arianespace, using its Russian-built Soyuz rockets that fly from the Kourou spaceport in South America. | A contract to launch the bulk of the initial 14 OHB-SSTL satellites has already been placed with French firm Arianespace, using its Russian-built Soyuz rockets that fly from the Kourou spaceport in South America. |
| But Mr Tajani announced at the London event that he would also be purchasing additional launch capacity from Arianespace. | |
| A 30m-euro "booking fee" is to be paid to Arianespace to secure the services of up three Ariane 5 rockets, which can loft four satellites at once (two more than Soyuz). | |
| But for this to happen, the rocket will need a special adapter to dispense the spacecraft in orbit, and an additional 30m-euro contract was signed with Astrium, the launcher's prime contractor, to develop the required equipment. | |
