Galileo launch 10. Completing the constellation

Today Europe’s next four Galileo satellites will be launched into orbit by Ariane 5 from Europe’s Spaceport in French Guiana. With this launch the Galileo constellation will reach 26 satellites in space, completing the constellation in overall numbers although further launches are needed to place back-up satellites in orbit. The launch comes at a time when Galileo is into its second year of Initial Operations, with a signal that is better than expected and that is now usable in all new mobile phones. This video looks at Galileo’s story so far and the way forward, interviewing Paul Verhoef, ESA Director of Navigation, and Valter Alpe, Galileo’s Satellite Production and Launch Campaign Manager.

Flight VA244 at a glance

For its fourth launch of the year, Arianespace will orbit four more satellites (satellites 23 to 26) for the Galileo constellation. This mission is being performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

For the third time, an Ariane 5 ES version will be used to orbit satellites in Europe’s own satellite navigation system; with all Galileo spacecraft having been launched to date by Arianespace. Ariane 6 will take over from 2020. Read more…

Europe’s next Galileo satellites in place atop Ariane 5

Europe’s next Galileo satellites have been put in place on top of the Ariane 5 launcher due to lift them from Europe’s Spaceport in Kourou, French Guiana on Wednesday 25 July.

Galileo satellites 23-26 were lifted to the top of their Ariane 5 launcher inside the BAF ‘Bâtiment d’Assemblage’ building on Wednesday 11 July, ahead of their Wednesday 25 July 2018 launch.

The launcher – appearing headless in the absence of its final payload – was moved from the BIL Launcher Integration Building, where it was assembled, to the BAF Final Assembly Building, ready for the Galileo satellites to be mated with it. Read more…

Next four Galileo satellites fuelled for launch

Europe’s next four Galileo satellites have been fuelled at Europe’s Spaceport in Kourou, French Guiana, in preparation for their launch on 25 July.

The four satellites were placed into their protective containers to be transported from the S1A processing building to the S3B payload preparation building, where they were filled with the hydrazine fuel that will keep the satellites manoeuverable during their 12-year working lives. Read more…

All four satellites are undergoing preparation for Ariane 5’s next Galileo launch

The four Galileo satellites for Arianespace’s next Ariane 5 mission at the service of Europe’s navigation system are coming together in their flight configuration, while parallel preparations continue with the mission’s heavy-lift launcher.

During pre-flight activity in French Guiana at the Spaceport’s S1A processing facility, these FOC (Full Operational Capability) spacecraft have undergone their fit-checks with the dispenser system to be installed on Ariane 5. Read more…

ESTEC’s new Galileo payload testbed facility

ESA microwave engineers took apart an entire Galileo satellite to reassemble its navigation payload on a laboratory test bench to run it as though it were in orbit – available to investigate the lifetime performance of its component parts, recreate satellite anomalies, and test candidate technologies for Galileo’s future evolution.
