Apparently this launch has been delayed, might be in the second part of this year?
Quote from: beidou on 05/01/2013 08:30 pmApparently this launch has been delayed, might be in the second part of this year?yes it appears to be delayed partly because Russian Authorities are trying to clear up Glonass-M backlog. If I remember correctly all of the remaining Glonass-M SC's have been completed and are sitting in corporations long term storage area awaiting their eventual launch onboard either Soyuz-2-1b or Proton-M.
Any ideas on how many Glonass-m are currently in storage?

Which generation of Glonass will have sufficiently low mass so that 2 may be orbited on Soyuz at a time?
Supposedly you can launch 2 Glonass-K1/K2 on Soyuz-2-1b/Fregat-M

Yes, but why are Glonass K1 being launched one at a time on Soyuz?

I know the idea was to launch two at a time, but since then they have got heavier. Can Soyuz haul two to orbit? Is such a requirement still needed considering last years launches were cancelled or posponed?
If I understand this correctly, Glonass K1 could be launched 2 at a time, but was never put into serial production because of the requirement to add CDMA, which resulted in the KM becoming the operational system; KM is too heavy to be launched 2 at a time on Soyuz. I suspect that perhaps 4 or 5 KM satellites could be launched at a time on Proton-M, if they fit within the fairing.

Older information says that a single Glonass-KM can be launched via Soyuz-2i1b/Fregat-M with newer information saying two via Soyuz-2-3V if that launcher is implemented.Latest information rules out any possibility of launch via Proton-M/Briz-M (Block-DM).
