Lightbulb (Bad orbit!) Arianespace Soyuz-STB flight VS09 with Galileo FOC-1/2, August 22, 2014
by Galactic Penguin SST 08-21-2014, 07:54 AM

A crucial milestone has been reached for what is one of Europe's largest spaceflight related program ever. After years of difficult development, arguments over how to fund the program, more than 5 years of signal testing and another 3 years of validation, the Galileo satellite navigation system - Europe's answer to their own GPS - finally reached the mass deployment phase where up to 30 satellites will be launched over the next few years to make the system a reality (as well as expansion of supporting structures on the ground). Today marks the launch of the first 2 satellites of the "FOC" (full operational capability) block - the group of more than 20 satellite ordered to complete the constellation. With the completion of this launch, the world's first satellite navigation system not tied to the military will be one step closer to be used on your fingertips.

PAYLOADS 1/2

Galileo FOC-1/2 navigation satellites



The Galileo satellite navigation system will consist of a total of 30 spacecraft in three planes in medium Earth orbit, which will each be occupied by nine satellites, and with three spares satellites distributed on the three orbital planes. At an altitude of 23,616 kilometers and an inclination of 56 degrees, the system will provide accurate positioning data to users as far north as 75 degrees longitude.

Although similar in design to the American GPS system and the Russian GLONASS navigation network, Galileo-FOC will be under the control of strictly civilian organizations. Galileo is the first joint program to be shared between the European Space Agency and the European Union.

In January 2010 the consortium consisting of OHB-System GmbH and SSTL was selected to built the first 14 Galileo-FOC (Galileo-Full Operational Capability) satellites of the system. OHB-System will act as prime contractor, build the busses while SSTL will provide the payloads. In January 2012, eight more satellites were ordered.

...and the launch has been scrubbed today due to weather conditions.

Rocket performing flawlessly till now. Second Fregat burn is at 16:06 UTC.

Have you noticed how altitude and speed go perfectly in sync with each other?
Is it really so, or was the display misconfigured?

Anyway, good launch!

Of course the display was wrong - unless you wanna believe that the Soyuz rocket reached 160+ km/s during its flight.

And the satellites have been deployed in the planned orbit! "Only" 4 Soyuz and 3 more Ariane 5 launches to constellation complete and global coverage!

VS09 Soyuz launch: Galileo satellites orbital injection anomaly
Kourou, August 22, 2014

Complementary observations gathered after separation of the Galileo FOC M1 satellites on Soyuz Flight VS09 have highlighted a discrepancy between targeted and reached orbit.

Investigations are underway. More information will be provided after a first flight data analysis to be completed on August 23, 2014.
US reports put the satellites in a 13700 x 25900 x 50 degree orbit, a bit off from the 23000 km, 55 degree circular orbit planned. Probably still within the satellites own capability to correct though....

Ha I did notice that the broadcasters were talking about how the Alt/Range/Speed parameters were being "verified" before being broadcast.

Oops.

Well even if they can't they should be OK to be put into service, although not in the desired orbital slot. Anyway Lavochikin has some explanation to do about what went wrong with the Fregat upper stage on its final burn!

The periapsis altitude maybe, but the 5 inclination error is hard to correct

Well inclination isn't that problematic for navigation satellites - there are GPS satellites now orbiting 2 off-inclination right now due to orbital drift and they are currently used as is.

23 August 2014

Following the announcement made by Arianespace on the anomalies of the orbit injection of the Galileo satellites, the teams of industries and agencies involved in the early operations of the satellites are investigating the potential implications on the mission.

Both satellites have been acquired and are safely controlled and operated from ESOC, ESAs Operations Centre in Darmstadt, Germany.

Further information on the status of the satellites will be made available after the preliminary analysis of the situation.
