Dual-transfer: Ariane 5s for Arianespace’s next heavy-lift missions are on the move in French Guiana

Arianespace’s flexibility and reactivity in responding to mission changes due to payload availability was underscored with this week’s simultaneous transfer of the 99th and 100th Ariane 5 launchers – which will be utilized on consecutive multi-passenger heavy-lift flights performed from French Guiana in 2018.

During activity at the Spaceport, the no. 99 Ariane 5 – an ES version that will orbit four Galileo FOC (Full Operational Capability) satellites on July 25 – was transferred from the Launcher Integration Building, where its basic build-up was performed, to the Final Assembly Building for payload installation. This upcoming mission is designated Flight VA244 in Arianespace’s numbering system.

The Spaceport’s Final Assembly Building was available due to the parallel rollout of the milestone 100th Ariane 5, which is scheduled for launch in early September carrying the Azerspace-2/Intelsat-38 satellite for Azercosmos and Intelsat, along with another payload to be announced. After moving out of the Final Assembly Building, this ECA version of Ariane 5 had a temporary stopover in the ELA-3 launch zone before heading to the Launcher Integration Building for its own pre-flight preparations.

Designated Flight VA243, the Ariane 5 ECA had been set for a late May liftoff, but its timing was shifted because additional technical checks were required for the mission’s originally-scheduled co-passenger.

Ready for payload integration

The transfer of Flight VA244’s Ariane 5 to the Final Assembly Building is a major step, signaling its readiness for integration of the mission’s four Galileo satellites – which will be released to a circular medium Earth orbit (MEO).

The processing of these satellites occurred at the Spaceport’s S1 building, was followed by their fueling in the S3B facility – enabling their subsequent installation atop a multi-passenger dispenser system.

As Europe’s own global navigation satellite system, Galileo is operated under civilian control, offering 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 European GNSS Agency (GSA) is responsible for operating the Galileo satellite navigation systems on behalf of the European Union.

Galileo spacecraft are built by OHB System in Bremen, Germany, and the navigation payloads are provided by Airbus-owned Surrey Satellite Technology in the United Kingdom.

Flight VA244: Arianespace’s Ariane 5 launch for the Galileo constellation and Europe

July 17, 2018


For its fourth launch of the year, Arianespace will orbit four more satellites (satellites 23 to 26) 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 third time, an Ariane 5 ES version will be used to orbit satellites in Europe’s own satellite navigation system; with all Galileo spacecraft having been launched to date by Arianespace. Ariane 6 will take over from 2020.

Arianespace is proud to mobilize its entire family of launch vehicles for the benefit of Europe’s ambitions and its independent access to space.

The Flight VA244 will be from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Friday, July 20, 2018 in Kourou, to authorize the start of operations for the final countdown.

Galileo is Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control. Currently providing Initial Services, Galileo is interoperable with GPS and Glonass, the U.S. and Russian global satellite navigation systems. By offering dual frequencies as standard, Galileo is set to deliver real-time positioning accuracy down to the meter range.

The constellation will count 24 operational satellites plus in-orbit spares, of which 22 already have been put into orbit by Arianespace.

In July 2017, ESA officially transferred the supervision of Galileo in-orbit operations to the European Global Navigation Satellite Systems Agency (GSA), on behalf of the European Union. After the VA244 launch, the GSA will be responsible for operating the satellites as soon as they are separated from the launcher. These operations of setting up and operating the system will be done in collaboration 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 an Airbus Defense and Space affiliate.

What slots are these satellites going into?

So far:
plane B has 4 satellites, 3 healthy and 1 in reserve (GSAT0204 was removed I think to look after it's clocks when several of the early satellites's clocks died)
plane A has 8 satellites, 4 still under commissioning (but there is doubt about GSAT0215's health as it is still sending dummy navigation data)
plane C has 8 satellites, 7 healthy and 1 in retirement (GSAT0104 I think has bad clocks)

Seems likely they finish off plane B?

They will be two healthy satellites short of the full 24 satellite constellation, however the two elliptical satellites are supposed to be perfectly usable if receiver manufacturers choose to include them.

Perhaps they will turn GSAT0204 back on to announce full services?

Ariane 5 reaches the launch zone for this week’s Arianespace mission with four Galileo satellites


Arianespace’s next Ariane 5 for liftoff this year has rolled out to the launch zone in French Guiana, clearing the way for the heavy-lift vehicle’s third mission carrying satellites for Europe’s Galileo navigation system.

The completed Ariane 5 ES version was transferred today atop its mobile launch table from the Final Assembly Building – where payload integration occurred – to the Spaceport’s dedicated ELA-3 launch complex.

Designated Flight VA244 in the company’s numbering system, this upcoming Ariane 5 mission – set for Wednesday, July 25 – will lift off at exactly 8:25:01 a.m. local time in French Guiana and deploy its quartet of Galileo spacecraft into medium Earth orbit (MEO) on a nearly four-hour flight.

During the flight sequence, 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 four Galileo satellites have a liftoff mass of 717.7 kg. each, with Ariane 5’s overall payload lift performance set at 3,287 kg.

Another launch for European institutional customers

Flight VA244 is Arianespace’s third Ariane 5 mission carrying European Galileo satellites, following previous launches in December 2017 and November 2016. Prior to that, the company orbited 14 of them on seven Soyuz missions performed between October 2011 and May 2016.
