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.

Galileo meets Galileo as launch draws near

The seventh and eighth Galileo satellites, set for launch together in nine days’ time, have been fitted together onto the dispenser that will carry them during their flight to orbit.

Fuelling Galileo

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.

Four Galileo satellites at ESA test centre

ESA engineers unwrapped a welcome Christmas present: the latest Galileo satellite. The navigation satellite will undergo a full checkout in Europe’s largest satellite test facility to prove its readiness for space.

Salvaged Galileo performs its first navigation fix

Galileo's fifth satellite – recently salvaged from the wrong orbit to begin navigation testing – has been combined with three predecessors to provide its very first position fix.

Galileo satellite recovered and transmitting navigation signals

Europe’s fifth Galileo satellite, one of two delivered into a wrong orbit by VS09 Soyuz-Fregat launcher in August, has transmitted its first navigation signal in space on Saturday 29 November 2014. It has reached its new target orbit and its navigation payload has been successfully switched on. 

Galileo duo handed over in excellent shape

A pair of fully functioning Galileo navigation satellites was recently delivered to its operators, as preparations get underway for the next round of launches.

Update on Galileo launch injection anomaly

Operations continue smoothly for Galileo Sat 5-6. Both satellites now have both sets of their solar arrays fully deployed and generating power.
