On September 2, 2010 at 04:53:50 MSK (00:53:50 UTC) the Space Forces conducted a successful launch of a Proton-M launcher from the Baykonur launch site. The launch took place from the launch pad No. 24 of the launch complex No. 81. The launcher, equipped with a DM-2 booster stage, successfully delivered into orbit three new Glonass-M satellites.
The satellites were deployed in the second orbital plane of the Glonass constellation. They are likely to receive designations Cosmos-2464, Cosmos-2465, and Cosmos-2466. NORAD catalog numbers and international designations of the satellites are 37139/2010-041C, 37138/2010-041B, and 37137/2010-041A respectively. The spacecraft joined the Glonass constellation that at the time of the launch consisted of 21 operational satellites.
The Space Forces and Roskosmos plan to bring the number of Glonass satellites to 27 (of which 24 should be operational) in 2010. The next launch of three Glonass-M satellites is currently scheduled for November 10, 2010. Also, Russia will launch the Glonass-K modification of the satellite in 2010 or in 2011. This launch will use a Soyuz-2-1A launcher with a Fregat booster stage.
