Two flagship European space programmes will combine on 17 November, as Galileo navigation satellites are carried into orbit by an Ariane 5 rocket for the first time.
Using this customised vehicle allows four Galileos to be launched together. The total number of satellites in orbit will rise from 14 to 18 – the single biggest increase of any navigation satellite constellation from a single launch.
Liftoff of Ariane flight VA233 is scheduled for 13:06 GMT (14:06 CET, 10:06 local time) on 17 November. Read more…
Galileo satellites lowered into position for installation atop the central core
Antonianna, Lisa, Kimberley and Tijmen – the latest Galileo spacecraft for Europe’s satellite navigation constellation – have been integrated with their Ariane 5 launcher in French Guiana for a November 17 Arianespace mission.
The four 715 kg satellites – named for winners of a European children’s drawing contest – were attached to their dispenser as a combined ‘upper composite’ and transported to the final assembly building on 31 October.
The next step saw them put on top of the upper stage of their customised launcher. Finally, on 3 November, the quartet was enclosed within a protective fairing – the last time they were seen by human eyes – to protect them from the onrushing atmosphere during ascent.
Arianespace previously has lofted 14 Full Operational Capability (FOC) and In-Orbit Validation (IOV) satellites for Galileo from French Guiana with seven missions utilizing its medium-lift Soyuz vehicle, along with two other Soyuz flights from the Baikonur Cosmodrome that deployed the GIOVE-A and GIOVE-B experimental satellites.
Next Thursday 17 November at 10.06 Kourou Time/14.06 CET an Ariane 5 will launch Galileo satellites for the first time. Equipped with a specially designed dispenser, the European launcher will deploy four satellites: Galileo Sat 15, 16, 17 and 18. This video explains the current status of the Galileo system.
On 17 November at 13:06 GMT (14:06 CET), a single Ariane 5 rocket is set to propel four Galileo satellites into orbit for the navigation constellation’s first-ever quadruple launch. Mission controllers are training intensively for the complex space delivery.
Ariane 5 will use a new payload dispenser to release four identical satellites into orbit in one go.
This will be the eighth Galileo launch, and will bring the number of satellites in space to 18. Once complete, the system will sport 24 operational satellites and a ground network to provide positioning, navigation and timing services. Read more…
The initial Ariane 5 to loft four global positioning satellites for Europe’s Galileo navigation system has begun its build-up at the Spaceport in French Guiana for a milestone Arianespace mission in November.
This launcher is an Ariane 5 ES version that began the integration process begining of October, with the cryogenic core stage’s positioning over a mobile launch pad, followed by integration of the vehicle’s two solid propellant boosters.
Designated as Flight VA233 in Arianespace’s numbering system, the mission’s Ariane 5 was assembled inside the Spaceport’s Launcher Integration Building. During activity in the Spaceport’s Launcher Integration Building, the heavy-lift vehicle for Arianespace Flight VA233 underwent the assembly process that began by mating Ariane 5’s two solid propellant strap-on boosters with the main cryogenic stage.

A transatlantic flight delivered four Galileo satellites to French Guiana on Tuesday 6th September, in preparation for a shared launch this November by Ariane 5, the first for Europe’s satnav constellation.
The satellites’ odyssey began the previous day, when they left ESA’s technical centre in Noordwijk, the Netherlands, where every Galileo satellite is tested.
Each satellite was placed into protective containers before leaving the cleanroom environment of the test facility. These containers incorporate sophisticated environmental control, satellite monitoring systems and shock absorbers. Read more…
