Does anyone know why Roskosmos is using a Soyuz 2.1b for this mission when a Soyuz-U could do the same job?
The launch of Glonass-K1 satellite is possibly postponed to 2013 and possibly Glonass-M satellite will be launched on December 25th instead of it.
Will this affects the processing of ILS missions (Satmex-7 is currently scheduled on December 27), or like before an ILS mission and a Russian federal mission can be processed simulatneously?

This will the second Glonass-K1 satellites, which will be followed by Glonass-K2 (planned in 2014) and Glonass-KM (after 2015)

I remember both Glonass-K1 and -K2 are test satellites and only Glonass-KM will be production satellites
Launcher for this mission is 14A14-1B Soyuz-2-1B/Fregat (220/1044).
There are rumour on NK forum that the launch has been delayed due to problems with Fregat upper stage (it should be returned to a factory) and Glonass-K1 satellite.
Аппаратуру системы управления разгонного блока "Фрегат", из-за выявленных технических проблем в которой был отложен запуск спутника "Глонасс-К", отправят в Москву для ремонта, сообщил во вторник "Интерфаксу-АВН" источник в ракетно-космической отрасли.По его словам, необходим ремонт или замена системы управления разгонного блока. Сам разгонный блок отправлять в Москву не планируется.
And I have a reliable source that confirms that there will be no more Soyuz launches from Plesetsk in 2012, and that the problem is with the Fregat upper stage.
