Lightbulb Galileo IOV-3/4 on Soyuz-2-1b/Fregat, October 12, 2012
by Galactic Penguin SST 10-11-2012, 04:41 PM

While all eyes are still on the "Falcon 8" () and what happened on Sunday night, the good old master of the all-kerosene rocket club is making another flight again on Friday. It will be a tense moment though, because the last flight of the most powerful variant of the R-7 family ended in embarrassing failure last December, and the passengers on Arianespace flight VS03 are the second of two pairs of in-orbit testing satellites for the European Galileo navigation system, now lagging behind schedule for years but finally almost ready for large scale deployment. Barring weather and technological constraints, we should see a beautiful afternoon liftoff from the rain-forests of the northern Amazon on Friday.

Galileo IOV-3/4 navigation satellites



The outcome of the first partnership between ESA and the European Commission, the 30-satellite Galileo navigation system will provide high-quality positioning, navigation and timing services to users across the whole world as a civil-controlled service offering guaranteed continuity of coverage.

Galileo’s Development and In-Orbit Validation phase was initiated in late 2003. This phase aims to perform an in-orbit validation of the system using a reduced constellation of four Galileo In-Orbit Validation (IOV) satellites – the minimum number to guarantee the provision of exact positioning and timing at test locations – in combination with Galileo’s terrestrial network of ground stations.

The first two IOV satellites were launched on 21 October 2011, with the next two following them in 2012. The four satellites perform a dual role, serving as a validation of the overall Galileo system while also being part the operational Galileo constellation – each IOV satellite being designed for a full 12-year lifespan providing navigation services to users worldwide.

Following launch of the IOV satellites, ESA’s ground station at Redu in Belgium will be employed first for the Launch and Early Phase (LEOP) and then, once the four satellites are operational, for the In-Orbit Test (IOT) programme.

This test programme will verify the performance of the navigation payload for the navigation signal: both the downlink (from the satellite, broadcast to users) and the uplink (from Galileo’s Ground Mission Segment, broadcast to the satellites for rebroadcast to users).
The results will be crucial to Galileo’s success, used to set benchmarks for their operational life and used as a reference across the entire Galileo constellation.

Default ARIANESPACE FLIGHT VS03 / GALILEO IOV-2 FM3 & FM4

http://www.arianespace.tv/


LANCEMENT ARIANESPACE VS03 / GALILEO IOV-2 FM3 et FM4

La Revue d'Aptitude au Lancement (RAL) s'est déroulée le jeudi 11 octobre 2012 à Centre Spatial Guyanais et a autorisé les opérations de chronologie pour le Vol Soyuz ST-b– GALILEO IOV-2 FM3 et FM4.
Pour son troisième lancement Soyuz depuis le Centre Spatial Guyanais, Arianespace mettra en orbite deux nouveaux satellites de la constellation européenne Galileo.
Avec Soyuz au Centre Spatial Guyanais, et avec Ariane 5 et Vega, Arianespace est le seul opérateur au monde à lancer toutes les charges vers toutes les orbites, des plus petits aux plus grands satellites géostationnaires, des grappes de satellites pour les constellations à la déserte de la Station spatiale internationale.
Le lancement sera effectué depuis l'Ensemble de Lancement Soyuz (ELS) en Guyane française, à un instant précis:

18:15:01 (UTC) le jeudi 20 octobre 2011
15:15:01 (Heure de Guyane)
20:15:01 (Heure de Paris)
14:15:01 (Heure de Washington, DC)
22:15:01 (Heure de Moscou)

----------------------------------------------------------------------------------------------------------
ARIANESPACE FLIGHT VS03 / GALILEO IOV-2 FM3 & FM4

THE LAUNCH READINESS REVIEW (RAL) took place in Kourou on Thursday October 11, 2012 and authorized count-down operations for the Soyuz ST-b – GALILEO IOV-2 FM3 & FM4 launch.
For its third Soyuz launch from the Guiana Space Center in French Guiana, Arianespace will place two new satellites of the Galileo constellation into circular orbit at 23,000 km, as part of the IOV (In Orbit Validation) program.
With the successful Soyuz launch from the Guiana Space Center, along with Ariane 5 and Vega, Arianespace is now the only launch services provider in the world capable of launching all types of payloads to all orbits, from the smallest to the largest geostationary satellites, along with clusters of satellites for constellations and missions to support the International Space Station.
The launch will be from the Soyuz Launch Complex (ELS) in Sinnamary, French Guiana.
Liftoff is scheduled for Friday, October 12, at exactly:

03:15:01 pm local time in French Guiana
18:15:01 in UTC
02:15:01 pm in Washington, D.C.
08:15:01 pm in Paris
10:15:01 pm in Moscow.

Fregat cut off as expected. Now in a 3 hours coasting phase. The Fregat orbit circulation burn is scheduled at 21:49 UTC with satellites separation at 21:59 UTC.

The satellites successfully separated a couple of minutes ago, after good 2nd Fregat burn, and control center in Toulouse has received first signals from them.
