Galileos take their seats on launcher upper stage

Europe’s ninth and tenth Galileo satellites have been secured on top of their Fregat upper stage in preparation for launch next week.

Mission team ready for Galileo launch

When the next pair of Galileo satellites is boosted into orbit next Friday, a team of mission control experts in Darmstadt, Germany, will spring into action, working around the clock to bring the duo through their critical first days in space.

EGNOS expands: aircraft use of precision satnav increasing

Reliable precision satnav for aircraft is already a reality in European skies, thanks to the ESA-designed EGNOS service. France’s Toulouse-Blagnac Airport recently hosted a dedicated EGNOS Day, demonstrating the service in action, both on the ground and in the air.

Four Galileos together in ESA test centre

Europe’s latest Galileo was unboxed at ESA’s technical centre in the Netherlands last month, bringing the total number of satellites at the site to four.

New Airbus A350 comes EGNOS-capable

The ESA-developed EGNOS system for sharpening the accuracy of satnav across Europe has been adopted by a growing number of airports to enable satellite-guided landing approaches. The new Airbus A350 airliner, currently entering service, comes fitted with it as standard.

Global satnav augmentation systems settle on common channels post-2020

The next decade’s aircraft pilots will be able to rely on enhanced, reliable satellite navigation signals on a seamless basis across much of the world, thanks to decisions made at the latest gathering of worldwide satnav augmentation system providers and experts.

Apprentices sought for ESA’s satnav summer school

Students still have time to join the ESA International Summer School on Global Navigation Satellite Systems, which will take place in Barcelona, Spain, at the end of August. 

Colloquium on scientific and fundamental aspects of Galileo

Europe’s Galileo satellite navigation system, currently under construction, will affect many aspects of daily life. It also promises to be a valuable scientific yardstick – a new highly precise measuring system to apply to our planet and everything on it, and even to space-time itself.

Galileo satellites well on way to working orbit

Their systems performing well, Europe’s recently launched Galileo navigation satellites have carried out a set of manoeuvres that will take them down to their working positions in orbit.

Galileo system updated and back to work

The worldwide Ground Mission Segment providing all Galileo navigation messages has completed a full-scale hardware and software migration to version V2.0, and is now fully operational again.

Sixth Galileo satellite reaches corrected orbit

The sixth Galileo satellite of Europe’s navigation system has now entered its corrected target orbit, which will allow detailed testing to assess the performance of its navigation payload.

Galileo satellites ready for fuelling as launcher takes shape

All the elements for this month’s Galileo launch are coming together at Europe’s Spaceport in French Guiana. As the two satellites undergo final testing and preparations, the first part of their Soyuz launcher has also been integrated.

Quality check on Galileo performance

In Roman times the milestone was the central method of navigation, with all distances fixed from a ‘golden milestone’ in the imperial capital. Today, navigation satellites have become the modern equivalent of milestones – but Rome still has a role to play.

Another two Galileo satellites have touched down in French Guiana ready to take their place in Europe’s satellite navigation constellation.

Service interruption for Galileo system upgrade

Galileo’s navigation messages will shortly stop being updated, in order to enable the migration of a new release for Galileo’s world-spanning ground mission segment.
