Four more Galileo satellites transmitting navigation signals

Galileo Satellites GSAT0215, GSAT0216, GSAT0217, and GSAT0218, launched in December 2017, have been commissioned for operational use.

Last four Galileo satellites usable for service provision

Since October 12, all Galileo satellites that were launched December last year are usable for service provision. NAGUs 2018023, 2018019, 2018020 and 2018018 announced the commissioning of Galileo satellites GSAT0215 (E21), GSAT0216 (E25), GSAT02017 (E27) and GSAT0218 (E31), increasing the number of satellites that are available for service provision to 18.

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.

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.

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.

Technicians on SCAPE (Self Contained Atmospheric Protection Ensemble) suits to fill Galileo satellites 23-26 with hydrazine fuel. This operation took place in the Guiana Space Centre's S3B payload preparation building on 29 June 2018
