At 00:15 MSK on October 3, 2011 (October 2, 2011, 20:15UTC), the Space Forces conducted a successful launch of a Soyuz-2.1b launcher from the Plesetsk launch site. The launcher, equipped with a Fregat boost stage, successfully delivered into orbit a Glonass-M navigation satellite.

The launch was originally scheduled for August 25, 2011 (UTC), but was delayed after a failure of a Soyuz launcher on August 24. Rescheduled for September 25, 2011 (UTC), it was further delayed to October 1, 2011 (UTC) for technical reasons and to October 2, 2011 (UTC) by weather conditions at Plesetsk.

The satellite has not been identified by its Cosmos designation, although it is likely to be designated Cosmos-2474. It received international designation 2011-055A and NORAD number 37829. The satellite joined the Glonass constellation that currently consists of 23 operational satellites and four satellites either in tests or undergoing maintenance. The satellite has been deployed in the first orbital plane of the constellation.

UPDATE: The satellite did receive the Cosmos-2474 designation. It was also identified as Glonass satellite No. 742.
