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)
