On October 26, 2007 Russia successfully launched Proton-K rocket from the Baykonur launch site (launch pad No. 24 of the launch complex No. 81). The launch took place at 11:35:24 MSK (07:35:24 UTC). The rocket, equipped with DM-2 upper stage, delivered three Glonass-M navigation satellites into orbit.

The satellites have been deployed in semi-synchronous circular orbits with altitude of about 19130 km and the inclination of 64.8 degrees. The satellites received international designations 2007-052A, 2007-052B, and 2007-052C. The NORAD catalog numbers they were assigned are 32275, 32276, and 32277. Russian names for the spacecraft have not been officially announced yet, but it is likely that the satellites will be designated Cosmos-2431, Cosmos-2432, and Cosmos-2433. Reported internal Glonass numbers are 18, 19, and 20.

The satellites are deployed in the third orbital plane of the Glonass constellation and are expected to be deployed in points 18, 20, and 22. The table below shows the current distribution of satellites. [The table will be updated as the information becomes available.]

The launch was originally scheduled on October 25, 2007, but was postponed because of a Kazakhstan holiday that day. Previous launch of Glonass satellites took place on December 25, 2006. Russia is expected to launch three more Glonass-M satellites on 25 December 2007.
