a Galileo dispenser is being developed for Ariane 5 ES. This dispenser will be able to carry and release four Galileo satellites in pairs into orbits at some 22 300 km altitude.
“But for Galileo Second Generation, the satellites could potentially incorporate electric propulsion – allowing them to target themselves directly instead of relying on the upper stage.” This would offer several advantages. Freeing up mass by doing without the upper stage means more satellites could be carried by individual rocket: up to three by Soyuz, while Ariane 5s carrying commercial telecom satellites could piggyback a quartet as secondary passengers. The lightweight Vega launchers might loft individual satellites. At the same time, the mass of each satellite could still increase – up to 1500 kg or more from the current 700 kg. Enlarging the satellite would enable an expanded navigation payload to support a greatly extended range of Galileo services.
"Observations taken after the separation of the satellites from the Soyuz VS09 (rocket) for the Galileo Mission show a gap between the orbit achieved and that which was planned," said launch service provider Arianespace, in a statement."They have been placed on a lower orbit than expected. Teams are studying the impact this could have on the satellites," it added.Arianespace declined to comment on whether their trajectories could be corrected, the AFP news agency reports.
The targeted orbit was circular, inclined at 55 degrees with a semi major axis of 29,900 kilometers. The satellites are now in an elliptical orbit, with excentricity of 0.23, a semi major axis of 26,200 km and inclined at 49.8 degrees

The article talks abut 6 to 8 birds per year. And I seriously doubt they can do an ES mission on 2015 with the sort of schedule pressure that they have on Ariane 5. Unless they have their "institutional" slot from the ATV moved to this.

In other words, may be they decided to keep one ES launch per year and switched payloads to Galileo.

Ariane-5 was seriously delayed because of the Optus-10 issues, and it already brought some delay from payload issues on 2013. So there's a lot of backlog. On the other hand, ESA pays a hefty subsidy and I imagine that they can reserve their slot for the ES.Normally Ariane-5 have a 24 month lead time. And the contract for the three ES was signed just last month, but they had done a lot of integration work previously, and they had already signed a framework agreement that included Soyuz and Ariane-5. Thus, I'd guess that this was just rubber stamping what they were working on previously. As I said before, I don't have any insight, but I would hazard a guess that ES won't be a schedule issue (save delays of the previous mission).Regarding Soyuz/Fregat, they are currently in stand down. It will take at least a couple of months before the combo is cleared for flight. If the thruster failure was a physical one, they might have to send the current Fregat back and get a new one, which might add some time. I would expect between 3 and 6 month delays on the Soyuz/Fregat schedule.On the other hand, while current orbit of FOC M1 is outside of the Galileo allowed specification, it's perfectly good for satellite validation. Thus, the payload issues should be worked out and the only delay should be for the Soyuz segment. I don't expect an additional ES because the Soyuz is much cheaper.I also expect that ESA will make an additional 6 satellite buy to replenish the fleet. But that's pure speculation on my part.
One voice close to the action says, “The problems of Galileo are not within the power of the Commissioner. At present, out of six satellites in orbit, only one is truly functional. Next launch, of two with Soyuz, could be in February, followed by an Arianne 5 launch in September-October [2015]. So, we’ve lost two full years — 2013 and 2014.”
