On 01 December Galileo satellites 13 and 14 begun transmitting navigation signals as fully operational members of the constellation.
The pair were launched from Europe’s Spaceport in French Guiana on May 24 (http://galileognss.eu/galileo-liftoff-replay-soyuz-vs15/).
After launch and maneuvers to reach their final orbital altitude, their navigation and search-and-rescue payloads were methodically switched on and checked out. Their performance was assessed in relation to the rest of Galileo system. Read more…
Named for the astronomer who pinpointed Earth’s true position in the Solar System, the Galileo satellite navigation system that will help Europe find its way in the 21st century now has 14 satellites in orbit after 24th May double launch.
Galileos 13 and 14 lifted off together at 08:48 GMT (10:48 CEST, 05:48 local time) atop a Soyuz rocket from French Guiana.
This seventh Galileo launch went by the book: the first three Soyuz stages placed the satellites safely into low orbit, after which their Fregat upper stage hauled them the rest of the way into their target medium-altitude orbit. Read more…
Arianespace has successfully launched the 13th and 14th satellites of the Galileo constellation. The company’s second Soyuz launch of the year took place on May 24 at 5:48 am local time (10:48 UTC) from the Guiana Space Center (CSG) in Kourou, French Guiana.
Today’s Soyuz success marks the 250th launch from the Guiana Space Center with its family of launchers. This total, composed of 229 Ariane flights, 15 with Soyuz and six liftoffs of Vega, confirms Arianespace’s operational performance over time for the benefit of all its clients.
Liftoff is scheduled for Tuesday, May 24, 2016 at exactly:
05:48:43 a.m., Local time (French Guiana)
04:48:43 a.m., Washington, D.C.
08:48:43 a.m., UTC
10:48:43 a.m., Central European Time
11:48:43 p.m., Moscow
The 15th Soyuz launch from the Guiana Space Center (CSG) will place two new satellites for Europe’s Galileo satellites navigation System into circular orbit. The launcher will be carrying a total payload of 1,599 kg.

The launch campaign is complete, the systems and teams at ESOC are ready. At Europe’s Spaceport, in Kourou, French Guyana, the satellite sits on top of its launcher, ready for the command that will send it soaring into space, watched intently by the experts at ESOC.
Ready to go to Space
With just hours to go before lift-off, the Mission Control Team at ESOC holds the final pre-launch briefing to review (one more time!) every detail of the mission plan.
At the briefing, team leaders and functional experts from the Mission Control Team are joined by the satellite’s Project Team from ESTEC as well as representatives from the launch service provider (in addition to the Agency’s own Spaceport at Kourou, ESA launches some satellites using commercial providers) and from the industrial contractor that built the satellite.

Arianespace’s new Spaceport processing facility has fueled another Fregat stage. This upper stage for the medium-lift Soyuz launcher will be used for the May 24 flight from French Guiana with two European Galileo navigation satellites.
Named the FCube (Fregat Fueling Facility), the purpose-built installation is utilized to “top off” Fregat upper stages during Soyuz launch campaigns at the Spaceport. In service since last year, the FCube supports Arianespace’s sustained launch pace, giving the company greater flexibility in managing its mission manifest, while also increasing launch capacity with Soyuz and its other launch vehicle family members: the heavy-lift Ariane 5 and lightweight Vega.

The Galileo programme is Europe’s initiative for a state-of-the-art global satellite navigation system, providing a highly accurate global positioning service under civilian control. The fully deployed system will consist of 30 satellites and the associated ground infrastructure. Galileo will be inter-operable with GPS and GLONASS. It will deliver state of the art services like Search and Rescue (SAR), encrypted signals or superior accuracy time-stamping.
Next a set of five videos describing the Arianespace Soyuz Flight VS15 is presented. Liftoff is scheduled for Tuesday, May 24, 2016 at 05:48:43 a.m. local time (French Guiana) / 04:48:43 a.m., Washington, D.C. / 08:48:43 a.m., UTC / 10:48:43 a.m., Central European Time / 11:48:43 p.m., Moscow

This week a unique, combined team of specialists are conducting final training at ESA’s ESOC mission control centre to prepare for the 24 May launch of Europe’s next Galileo satellites, a dual launch on a Soyuz rocket from Kourou.
The team comprises over 40 experts drawn from ESA and from France’s CNES space agency, supported by additional specialists at both agencies in areas such as flight dynamics and ground stations.
Within the combined flight control team, each position is paired with its counterpart from the other agency and mixed “CNESOC” shifts will rotate to conduct operations around the clock. Read more…
Another pair of Galileo navigation satellites is scheduled for launch by a Soyuz rocket this 24 May from Europe’s Spaceport in French Guiana, bringing the Galileo system a step closer to operational use.
