New launch date for Galileo

Arianespace has announced the next launch attempt for Soyuz VS09 with Europe's fifth and sixth Galileo satellites is 22 August at 12:27 GMT, 14:27 CEST.

Galileo launch postponed

Arianespace has decided to postpone the launch of Soyuz flight VS09 carrying Europe's fifth and sixth Galileo satellites. This is due to unfavourable weather conditions over the Guiana Space Centre.

ESA and CNES experts ready for Galileo’s first orbits

Lift-off for Galileo satellites 5 and 6 is set for Thursday, 21 August, at 12:31 GMT (14:31 CEST) on a Soyuz rocket from the Guiana Space Centre, French Guiana.

Just 9 minutes and 23 seconds later, the Fregat upper stage carrying the payload will separate from the Soyuz third stage, and conduct a pair of engine burns separated by an approximately three-hour ballistic coast phase.

Three hours and 47 minutes after launch, the Galileo satellites will separate into free-flight orbit, 23 522 km above Earth. On board each satellite, an automatic sequence will be triggered, switching the spacecraft on, booting up the onboard software, deploying a pair of solar arrays and orienting the spacecraft toward the Sun.

Twin Galileos meet, ready for Thursday’s launch

Final functional testing of Europe’s twin Galileo navigation satellites has been completed at Europe’s Spaceport in French Guiana, on track for launch this Thursday.

New video: Galileo towards the future

The special significance of next Thursday's launch for the Galileo system as a whole is highlighted in a new ESA video, including an interview with Didier Faivre, the Agency's Director of the Galileo Programme and Navigation-related Activities.

Call for Media: Press briefing on launch of Galileo satellites 5-6

The next satellites in Europe’s Galileo satellite navigation system will be launched on 21 August, ushering in the system deployment phase and paving the way for the start of initial services. Media are invited to take part in an audio briefing on Wednesday, 20 August.

Galileo’s ‘midwives’ stand ready for launch

Galileo’s post-launch team at ESA have finalised their preparations for taking control of the twin satellites being launched next month.

Galileo: it’s all about the time

Europe’s Galileo satellite navigation system – the combination of satellites in space and stations on the ground – forms a planetary scale timepiece. Current testing shows it keeping very good time indeed – around 10 billionths of a second on average. 

Galileo fixes worldwide

Pioneer Galileo navigation fixes recognised by ESA

Billions of satnav position fixes are performed daily, but determining your place in the world using Europe’s Galileo system is quite new. So ESA offered to issue certificates for the very first 50 Galileo fixes – provoking responses from across the whole world.

Galileo's story so far

Apprentices sought for satnav summer school

Students still have time to join the ESA International Summer School on GNSS, taking place in the Czech Republic this July. The 10-day course will cover all aspects of satellite navigation, up to and including the creation of a satnav-based business.

Touchdown

Next Galileo satellites arrive at Europe’s Spaceport

Europe’s two latest Galileo navigation satellites touched down today at Europe’s Spaceport in French Guiana, ready for their joint launch this summer.

Unboxing Galileo

Latest Galileo satellite arrives at ESA’s test centre

Europe’s latest Galileo navigation satellite has arrived at the Agency’s technical centre in the Netherlands for testing, as the previous two satellites are prepared for shipping to French Guiana for launch this summer.

Sea trial

Galileo: following the trail of the dragon-ships

Results are being processed from the first Galileo maritime trials outside of mainland Europe. The long-range, high-latitude testing spanned the North Sea, following the same historical sailing route that Viking dragon-ships used 1200 years ago.

Electric thrusters may steer Galileo in future

Future Galileo navigation satellites might adopt electric propulsion to reach their final orbits, with the weight savings offering larger payloads and a broader range of services in the 2020s.
