I saw an article on phys.org just now about failed clocks on the Galileo sats already launched.  Each satellite has two rubidium and two hydrogen maser clocks (one primary and one backup each, IIRC), and of the 18 sats launched, 3 rubidium and 6 hydrogen clocks have failed.  ESA is exploring how to proceed.

Jan Woerner, the director general of the European Space Agency (Esa), told a meeting with reporters today:
 "Everybody is raising this question: should we postpone the next launch until we find the root cause, or should we launch?

"You can give both answers at the same time. You can say we wait until we find the solution but that means if more clocks fail we will reduce the capability of Galileo. But if we launch we will at least maintain if not increase the [capability], but we may then take the risk that a systematic problem is not considered. We are right now in this discussion about what to do."

Each Galileo satellite carries two rubidium and two hydrogen maser clocks. The multiple installation enables a satellite to keep working after an initial failure.

All 18 spacecraft currently in space continue to operate, but one of them is now down to just two clocks.

Esa staff at its technical centre, ESTEC, in the Netherlands are trying to isolate the cause the of failures - with the assistance of the clock and satellite manufacturers. (It is understood engineers have managed to get one stopped hydrogen clock restarted).

Esa is also in contact with the Indian space agency which is using the same clocks in its sat-nav system. So far, the Indians have not experienced the same failures.

In this article, ESA and the European commission have agreed to delay Galileo's next launch by 3-4 months, to late 2017.

lets say its rather busy right now ;)
Its tricky issue to get to the bottom of, you can only test so much on-ground and everything worked fine on-ground.

keep in mind we have 4 clocks per satellite, so we can continue to operate.

But yes, it looks like another end of the year launch, arianespace x-mas hats included...
First, loads of work ahead.

This massive atomic clock failure can easily defer the launch into 2018 if root cause is not quickly hunted out...

Although its an issue, 6 out of 72 clocks is hardly massive.

plan is to launch before end 2017, this plan includes understanding the issue, fixing it, re-test and re-qual.
So, yes we will be busy :)

A failure rate of 8.3% is pretty bad.

The correct figure of merit is mean time to failure, I'm not so worried about the IOV failures, but the FOC are much more worrisome if you consider the required mean life of the satellites.

In fact, 10 out of 72 clocks have had problems, so the failure rate is 13.9%, which is even worse.

Last Galileo leaves ESA’s Test Centre

4 September 2017
The last of 22 Galileo satellites has departed ESA’s Test Centre in the Netherlands – concluding the single longest and largest scale test campaign in the establishment’s history.

Cocooned in a protective container for its journey – equipped with air conditioning, temperature control and shock absorbers – the final Galileo satellite left the establishment by lorry on 24 August.

Doesn't the last satellite mean FOC FM22? I think FOC FM22 will not launched in this mission.

The Ariane 5 for Arianespace’s next Galileo mission arrives at the Spaceport

Elements for Arianespace’s Ariane 5 mission in December have been delivered to the Spaceport in French Guiana for the heavy-lift launcher’s second flight at the service of Europe’s Galileo global satellite navigation system.

These components arrived this month in French Guiana aboard the MN Colibri, which is one of two sea-going roll-on/roll-off ships that transport launcher hardware from Europe to the South American launch site for Arianespace’s family of launch vehicles.

The year-end launch will orbit four more Galileo spacecraft, to be deployed into medium Earth orbit from a dispenser system on the Ariane 5 ES launcher version equipped with a re-ignitable upper stage. Galileo is designed to provide a new European global satellite navigation system with precision positioning services under civilian control.

A December liftoff for Ariane 5 and its Galileo satellites

Designated Flight VA240 in Arianespace’s launcher family numbering system, the mission is targeted for December 12. As the latest mission carrying Galileo satellites, Flight VA240 is to be performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

Galileo is funded by the European Union, with overall responsibility for management and implementation held by the European Commission. ESA is assigned design and development of the new generation of systems and infrastructure.

Arianespace already has launched 18 Galileo spacecraft, with four being orbited on a previous Ariane 5 mission (Flight VA233 in November 2016), and the others lofted by seven medium-lift Soyuz vehicles carrying two satellites each.

Ariane 5   September 28, 2017

Galileo satellites are readied for Flight VA240 in December

In other activity at the Spaceport, the first two satellites for Arianespace’s Flight VA240 with Ariane 5 have begun their checkout. Targeted for a liftoff on December 12 carrying a quartet of Galileo navigation spacecraft, this mission will be performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

Arianespace already has launched 18 Galileo spacecraft, with four being deployed into medium Earth orbits on a previous Ariane 5 mission (Flight VA233 in November 2016), and the others lofted by seven medium-lift Soyuz vehicles carrying two satellites each.

Ariane 5   October 24, 2017
Four Galileo spacecraft are prepared for their December Ariane 5 launch

Payload processing for Arianespace’s second Ariane 5 mission in support of Europe’s Galileo global navigation system has reached full speed, with all four satellites now at the Spaceport.

Liftoff of Arianespace’s Ariane 5 with these satellites is targeted for December 12, coming after the heavy-lift workhorse’s previous flight at the service of Galileo, which successfully delivered four other spacecraft to medium-Earth circular orbit in November 2016.

The upcoming mission is designated Flight VA240 in Arianespace’s launcher family numbering system, denoting the 240th performed with an Ariane-series vehicle from the Spaceport. It also will be the company’s 11th and final launch in 2017, closing out a busy year of space lift activity.

A global navigation system for Europe

As the latest mission carrying Galileo satellites, Flight VA240 is to be conducted on behalf of the European Commission under a contract with the European Space Agency (ESA). Galileo is funded by the European Union, with overall responsibility for management and implementation held by the European Commission. ESA is assigned design and development of the new generation of systems and infrastructure.

Arianespace already has launched a total of 18 Galileo spacecraft, including the four orbited by Ariane 5 in November 2016, plus the others lofted by seven preceding medium-lift Soyuz vehicles that carried two satellites each.

Galileo quartet fuelled and ready to fly

21 November 2017
Europe’s next four Galileo navigation satellites and the Ariane 5 rocket due to lift them into orbit are being readied for their 12 December launch from Europe’s Spaceport in Kourou, French Guiana.

Tuesday saw Galileo satellites 19–22 declared ready for flight, along with their Ariane. Combined activities are now under way, culminating in the satellites meeting their rocket in the Final Assembly Building.

The satellites were flown in pairs to French Guiana last month. Once safely unboxed in the Spaceport’s cleanroom environment, they were tested to ensure they had suffered no damage during their transatlantic flights.

Next came their ‘fit check’, when they were mechanically and electrically linked one by one to the dispenser that will carry them during their ascent to the target 23 500 km-altitude orbit, before releasing them into space.

 
Four Galileos on Ariane 5
Last Friday saw the satellites filled with enough fuel to fine-tune their orbits and orientation during their projected 12 year working lives. Next, they will be attached to their dispenser together for the final time.

In parallel, their customised Ariane 5 is being assembled. Two solid-propellant boosters were mated with its main cryogenic stage before the addition of the interstage that carries the electronics to control the vehicle.

Next came the addition of the storable propellant stage, powered by a reignitable engine, which will deliver the quartet to their target orbit.

Once fully checked, the Ariane will be moved to the final building for the addition of the satellites atop their dispenser, sealed within their protective fairing.

This launch will bring the total Galileo constellation to 22, boosting the global availability of navigation signals. Galileo began Initial Services just under a year ago, the first step before full operations, on 15 December.

About Galileo

Galileo is Europe’s own satellite navigation system, consisting of both the satellites in space and their associated ground infrastructure, to provide an array of positioning, navigation and timing services to Europe and the world.

The definition, development and in-orbit validation phases were carried out by ESA, and co-funded by ESA and the European Commission. This phase created a mini-constellation of four satellites and a reduced ground segment set up to validate the overall concept, ahead of further deployment.

The current Full Operational Capability phase is fully funded by the EU and managed by the Commission. The Commission and ESA have a delegation agreement by which ESA acts as design and procurement agent on behalf of the Commission.

Ariane 5 and its Galileo satellites are prepared for Arianespace’s December 12 mission


The Ariane 5 for Arianespace’s December 12 year-ending flight for 2017 has completed its initial build-up at the Spaceport in French Guiana – where preparations also are moving ahead with four satellite passengers that will further expand Europe’s Galileo global navigation system once in their final orbit.

During activity in the Spaceport’s Launcher Integration Building, this heavy-lift vehicle for Arianespace Flight VA240 underwent the assembly process that began by mating its two solid propellant strap-on boosters with the main cryogenic stage.

The next step was integration of Ariane 5’s vehicle equipment bay, which serves as the launch vehicle’s “brain,” providing autonomous control during the various mission phases.

The Ariane 5 ES difference

It was followed by installation of the EPS storable propellant stage, powered by a re-ignitable engine that operates with MMH and N2O4 propellants. This differentiates the Ariane 5 ES configuration from Arianespace’s Ariane 5 ECA version – which has a cryogenic upper stage and typically is used on Arianespace missions with telecommunications satellites to geostationary transfer orbits.

After completion of verifications and systems checkout by production prime contractor ArianeGroup, the Ariane 5 ES launch vehicle will be moved to the Spaceport’s Final Assembly Building for payload integration and readiness for rollout to the launch zone.

The mission’s ongoing payload preparations – which so far included the checkout and fit-check procedure for each of the four Galileo satellites – took place inside the Spaceport’s S1A processing facility. This involved a one-by-one verification of the spacecraft’s interface with the payload dispenser that will release them into circular orbit during the mission.

Galileo satellites checked…and fit

After the fit-check procedure in the S1A facility, the four satellites were readied for transfer to the S3B payload preparation center for fueling.

For Ariane 5’s December 12 mission, the heavy-lift vehicle will carry its quartet of Galileo satellites (weighing approximately 715 kg. each) and their dispenser system for a medium-Earth orbit deployment.

Galileo is the European initiative to develop a global satellite navigation system. Under civilian control, it will offer a guaranteed, high-precision positioning service. As a European Union-funded program, the Galileo constellation will comprise 24 operational satellites, along with spares.

Overall responsibility for Galileo’s management and implementation is held by the European Commission, with the European Space Agency assigned design and development of the new generation of systems and infrastructure.

Ariane 5’s mission with the four Galileo spacecraft will close out a busy year of launch activity for Arianespace, which has performed 10 missions from French Guiana so far in 2017 – all of which were successful. The flights to date involved five launches of the heavy-lift Ariane 5, two with the medium Soyuz and three with the lightweight Vega.

Ariane 5   
December 1, 2017

Galileo satellites for Arianespace’s December 12 mission are ready for launcher integration

As preparations advance for Arianespace’s year-ending flight from the Spaceport in French Guiana, the mission’s payload of four Galileo navigation satellites is now ready to join up with its Ariane 5 launcher.

The spacecraft have been fueled and installed on their multi-payload dispenser system, clearing the way for transfer from the Spaceport’s S3B clean room to Ariane 5’s Final Assembly Building.

Designated Flight VA240, the upcoming mission will mark Arianespace’s second use of an Ariane 5 ES version to loft spacecraft for Europe’s Galileo global navigation system – following the first four-passenger launch in November 2016 on the heavy-lift launcher. This came after seven previous missions using the medium-lift Soyuz, which carried a pair of operational satellites each.

Flight VA240 at the service of a European initiative

Galileo is the European initiative to develop a global satellite navigation system. Under civilian control, it will offer a guaranteed, high-precision positioning service and features innovative technologies developed in Europe for the benefit of all citizens.

The European Commission holds overall responsibility for Galileo’s management and implementation, with the European Space Agency assigned design and development of the new generation of systems and infrastructure.

Each of the Galileo passengers for Flight VA240 weighs approximately 715 kg. and was built by OHB System in Germany, with U.K.-based Surrey Satellite Technology supplying the navigation payload. All four will be deployed into medium-Earth orbit by Arianespace.

Scheduled for a December 12 liftoff, Ariane 5’s mission with the four Galileo spacecraft will close out a busy year of launch activity for Arianespace.

The company has conducted 10 missions from French Guiana so far in 2017 – involving five launches of the heavy-lift Ariane 5, two with the medium Soyuz and three with the lightweight Vega.

Flight VA240: Arianespace’s second Ariane 5 launch for the Galileo constellation and Europe


December 5, 2017 – For its 11th launch of the year, and the sixth Ariane 5 liftoff from the Guiana Space Center (CSG) in French Guiana during 2017, Arianespace will orbit four more satellites for the Galileo constellation.

 This mission is being performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

 For the second time, an Ariane 5 ES version will be used to orbit satellites in Europe’s own satellite navigation system. At the completion of this flight, designated Flight VA240 in Arianespace’s launcher family numbering system, 22 Galileo spacecraft will have been launched by Arianespace with Soyuz and Ariane 5 launchers.

 A final Ariane 5 ES mission will deploy four additional Galileo constellation satellites in 2018, after which Ariane 6 takes over from 2020-2021 – with its initial two Galileo launches contracted by ESA on behalf of the European Commission in September 2017.

 The Flight VA240 will be from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

 The Launch Readiness Review (LRR) will take place on Friday, December 8, 2017 in Kourou, to authorize the start of operations for the final countdown.

Galileo is Europe’s own global navigation satellite system. Under civilian control, Galileo offers guaranteed high-precision positioning around the world. Its initial services began in December 2016, allowing users equipped with Galileo-enabled devices to combine Galileo and GPS data for better positioning accuracy.

 The complete Galileo constellation will comprise a total of 24 operational satellites (along with spares); 18 of these satellites already have been orbited by Arianespace.

 ESA transferred formal responsibility for oversight of Galileo in-orbit operations to the GSA (European GNSS Agency) in July 2017.

 Therefore, as of this launch, the GSA will be in charge of the operation of the Galileo satellite navigation systems on behalf of the European Union. GSA will be responsible for operating these satellites as soon as they separate from the launcher. Satellite positioning operations and system operation will be carried out in conjunction with ESA.

 The Galileo satellites are built by prime contractor OHB System in Bremen, Germany, with the payloads supplied by UK-based Surrey Satellite Technology Ltd (SSTL), which is 99% owned by Airbus Defence and Space.

The integration of Galileo satellites with Ariane 5 is complete for Arianespace’s year-ending heavy-lift mission

Arianespace’s Ariane 5 is now complete and ready for its mission next week from the Spaceport in French Guiana, which will orbit four more spacecraft to join the European Galileo constellation of navigation satellites.

During activity in the Spaceport’s Final Assembly Building, the Ariane 5’s build-up process was completed with the lowering of its ogive-shaped payload fairing over the four satellite passengers – which previously were positioned atop the launcher’s core section.

Following final check-out, Ariane 5 will be ready for its rollout to the ELA-3 launch zone on Monday, December 11, positioning this vehicle for a liftoff the next day at exactly 3:36:07 p.m., local time in French Guiana.

The four Galileo satellites, which are clustered around a multi-passenger dispenser system, will be deployed in two phases during the mission to medium Earth orbit (MEO) lasting 3 hours, 55 minutes.

Arianespace’s Ariane 5 at the service of Galileo

Ariane 5’s afternoon liftoff on December 12 will be the year-ending mission in 2017 for Arianespace – completing a busy 12 months that already have involved 10 flights from the Spaceport: five performed with the heavy-lift workhorse, three utilizing the lightweight Vega and two with the medium-lift Soyuz.

Designated Flight VA240 in Arianespace’s numbering system, next Tuesday’s mission will mark the second time an Ariane

Ariane 5 moves to the launch zone for Arianespace’s mission with four Galileo satellites

Arianespace’s Ariane 5 for Flight VA240 nears the completion of its rollout to the Spaceport’s ELA-3 launch zone for tomorrow’s afternoon liftoff with four Galileo satellites.

The next four spacecraft to join Europe’s Galileo satellite navigation system are one step closer to launch following the rollout of their Ariane 5 at the Spaceport in French Guiana.

With today’s transfer from the Spaceport’s Final Assembly Building to the ELA-3 launch zone, Arianespace’s year-ending mission of 2017 can now enter its final countdown for liftoff tomorrow afternoon.

Designated Flight VA240 in Arianespace’s launcher family numbering system, the December 12 launch will deploy its Galileo spacecraft cluster into medium Earth orbit (MEO) at the completion of a mission lasting 3 hours, 55 minutes.

During the trajectory, Ariane 5’s storable propellant upper stage will perform two burns, which are to be separated by a 3-hour, 8-minute ballistic phase.

The satellites have a liftoff mass of approximately 715 kg. each, with Ariane 5’s overall payload lift performance on Flight VA240 set at 3,282 kg.

Not the best commentary I've ever heard. Did she seriously say that LOX/LH2 burns at absolute zero?

Edit: Nope, just found a replay. She stumbled over her words a bit, but was referring to the propellant temperature, not the combustion temperature. That being said, 20K is far from absolute zero.

I don't think it is.
On the picture posted by Chris Berger you can see the BIF and BAF, it's at the launcher preparation area of Ariane 5.
This is most likely the new solid preparation facility. (Horizontal stage assembly and stowage)
In this Youtube video @ 35:30, 38:50 & 40:25 you can see the drone footage.


I've named the buildings on a screenshot from 40:25. Google maps location
Edit: I've added a screenshot from 35:30.

Don't cheer to early ;), that happened during launch of FOC sat 1&2, Soyuz VS07, sat 5&6.
Not that I'm expecting a anomaly, but wait untill Arianespace & ESA call the launch successful.
That's after acquisition of signal (and orbit confirmation  :-[) / health checks.

Explanation of the long verification proces (refers to VS07: FOC-M1)
"It's time for a drink, I need one"  ;D

Edit: (my own explanation)
SpaceX calls a mission successful after they have deployed the satellite succesfuly
Arianespace normally awaits until acquisition of signal from the satellite(s) (one of the first steps of satellite start up).
With this Galileo launch, they waited until the health checks were completed, and they had verification the satellites are in the correct orbit. So they were really conservative during this launch. The drone footage was a nice distraction during the waiting period.
ZachS09's post was at the normal time Arianespace called a mission successful. So Zach timing was perfect.

From the VA240 launch kit: MEO Plane A (page 3)
So FOC-M8 (the next four Galileo satellites) wil go to Plane B. After this they have all slots in all three planes filled.
(26 satellites launched but FOC-M1 (Sat 5&6) in wrong orbit)
Most likely the two A62 launches will replace the IOC Galileo satellites. (or some with several failed clocks)
So Galileo will reach full operational state after the next Ariane 5 ES launch, but with pore reliability because several sats have failed clocks, unfortunately.

Another funny fact:
This launch used the 14M long Medium Fairing. (Ariane 6 will have two failing options 20m & 14m)

Arianespace Flight VA240 / Galileo FOC-M7 / SAT 19-20-21-22


arianespace
Published on Dec 12, 2017

Arianespace has successfully launched satellites 19, 20, 21 and 22 in the Galileo constellation, using an Ariane 5 heavy launcher on behalf of the European Commission (DG GROW) and under a contract with the European Space Agency (ESA).

The launch took place on December 12, 2017 at 3:36 p.m. (local time) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana.

Today’s launch was the ninth from CSG for the Galileo satellite navigation system, and the second using the Ariane 5 ES version of this launch vehicle. Arianespace has now orbited a total of 22 Galileo satellites, using Soyuz and Ariane 5 launchers.

A last Ariane 5 ES will orbit four more Galileo satellites in 2018, then Ariane 6 will take over in 2020-2021.

Today’s launch was the 11th and final of 2017 for Arianespace, and the sixth during the year for Ariane 5, which also marked the 82nd successful mission in a row for the heavy-lift launcher.

Press Release

N°25-2017

Paris, 13 December 2017


Galileo launch brings navigation network close to completion

Europe has four more Galileo navigation satellites in the sky following their launch on an Ariane 5 rocket. After today’s success, only one more launch remains before the Galileo constellation is complete and delivering global coverage.

Ariane 5, operated by Arianespace under contract to ESA, lifted off from Europe’s Spaceport in Kourou, French Guiana at 18:36 GMT (19:36 CET, 15:36 local time), carrying Galileo satellites 19–22. The first pair of 715 kg satellites was released almost 3 hours 36 minutes after liftoff, while the second pair separated 20 minutes later.

They were released into their target 22 922 km-altitude orbit by the dispenser atop the Ariane 5 upper stage. In the coming days, this quartet will be steered into their final working orbits. There, they will begin around six months of tests – performed by the European Global Navigation Satellite System Agency (GSA) – to check they are ready to join the working Galileo constellation.

This mission brings the Galileo system to 22 satellites. Initial Services began almost a year ago, on 15 December 2016.

“Today’s launch is another great achievement, taking us within one step of completing the constellation,” remarked Jan Wörner, ESA’s Director General

“It is a great achievement of our industrial partners OHB (DE) and SSTL (GB) for the satellites, as well as Thales-Alenia-Space (FR, IT) and Airbus Defense and Space (GB, FR) for the ground segment and all their subcontractors throughout Europe, that Europe now has a formidable global satellite navigation system with remarkable performance.

Paul Verhoef, ESA’s Director of Navigation, added: “ESA is the design agent, system engineer and procurement agent of Galileo on behalf of the European Commission. Galileo is now an operating reality, so, in July, operational oversight of the system was passed to the GSA.

“Accordingly, GSA took control of these satellites as soon as they separated from their launcher, with ESA maintaining an advisory role. This productive partnership will continue with the next Galileo launch, by Ariane 5 in mid-2018.

“Meanwhile, ESA is also working with the European Commission and GSA on dedicated research and development efforts and system design to begin the procurement of the Galileo Second Generation, along with other future navigation technologies.”

Next year’s launch of another quartet will bring the 24‑satellite Galileo constellation to the point of completion, plus two orbital spares.

Arianespace’s winning formula for Galileo: 5 + 4 = 22

Lifting off at the exact moment set for the launch of Flight VA240, Arianespace’s Ariane 5 begins its ascent from the Spaceport with four Galileo navigation satellites.

The Galileo constellation increased by four spacecraft today following an Ariane 5 launch from the Spaceport in French Guiana – bringing the total number of European navigation satellites orbited by Arianespace to 22.

This afternoon mission, designated Flight VA240 in Arianespace’s launcher family numbering system, was performed from the Spaceport’s ELA-3 launch zone, with Ariane 5 deploying its four passengers during a mission lasting 3 hours, 55 minutes.

Flight VA240 was the second to utilize the workhorse Ariane 5 – supplied by production prime contractor ArianeGroup – in lofting operational Galileo satellites. It followed another four orbited by Arianespace on an Ariane 5 in 2016, and 14 others launched in pairs aboard the company’s Russian-built Soyuz vehicles during seven missions performed between 2011 and 2016.

11 Arianespace launches in 2017 with Ariane 5, Soyuz and Vega

Today’s launch wrapped up another successful year of activity for Arianespace, as noted by Chief Executive Officer Stéphane Israël during comments from the Spaceport. “Thanks to the year’s flawless operation of our launch vehicle family – six Ariane 5 flights, two with Soyuz and three by Vega – our track record for 2017 is once again outstanding,” he said.


Flight VA240 was Arianespace’s 11th mission in 2017, and wrapped up another busy year of activity for the launch services company.

The four satellites carried on Flight VA240 were named after European children who created artwork in a Galileo drawing competition on the themes of space and aeronautics. As a result, the latest navigation spacecraft in Galileo’s constellation are called Nicole, Zofia, Alexandre and Irina – named after youngsters from the European countries of Austria, Poland, Portugal and Romania, respectively.

For Flight VA240, the four Galileo satellites weighed approximately 714 kg. each, and were deployed from a dispenser system that released the passengers in two sets during an interval of 20 minutes. The Ariane 5’s overall payload lift performance to medium Earth orbit (MEO) was set at 3,283 kg.

The spacecraft were built by prime contractor OHB System in Bremen, Germany, with the payloads for each satellite supplied by U.K.-based SSTL (Surrey Satellite Technology Ltd), which is 99% owned by Airbus Defence and Space.

Galileo: Europe’s civilian-controlled navigation system

As Europe’s own global navigation satellite system, Galileo is operated under civilian control, offering guaranteed high-precision positioning around the world. The Galileo program is funded and owned by the European Union. The European Commission has overall responsibility for the program – with Flight VA240 performed by Arianespace on behalf of the European Commission under contract with the European Space Agency (ESA).

Following today’s launch, the GSA (European GNSS Agency, in charge of managing and operating the EGNOS and Galileo satellite navigation systems for the European Union), became responsible for operating these satellites after their separation from the launcher. Satellite positioning operations and system operation will be carried out in conjunction with ESA.

Looking ahead to next year, Arianespace’s 2018 launch activity will begin on January 25 with an Ariane 5 mission to geostationary transfer orbit (GTO). This mission will carry two relay satellites: SES-14 for the Luxemburg-based operator SES; and Al Yah 3 for Al Yah Satellite Communications Company, located in the United Arab Emirates at Abu Dhabi.

Regarding the naming convention

Galileo-FOC FM18 is GSAT0218 is Galileo SAT 22 is Irina.

Is that correct and did I miss any other name that is used? (Thanks)
