On December 25, 2007 Russia successfully launched Proton-M rocket from the Baykonur launch site (launch pad No. 24 of the launch complex No. 81). The launch took place at 22:32:34 MSK (19:32:34 UTC). The rocket, equipped with DM 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 64.7 degrees. The satellites received international designations 2007-065A, 2007-066B, and 2007-067C. At this time, the only available NORAD catalog number is 32393 for the 2007-065A satellite. Two other satellites are likely to be assigned NORAD numbers 32394 and 32395. Official Russian designations for the spacecraft have not been announced yet, but it is likely that the satellites will be designated Cosmos-2435, Cosmos-2436, and Cosmos-2437. [UPDATE 02/11/08: The satellites received designations Cosmos-2434, Cosmos-2435, and Cosmos-2436.] Reported internal Glonass numbers are 21, 22, and 23. The satellites are deployed in the second orbital plane of the Glonass constellation, complementing three active satellites there. The table below shows the current distribution of satellites. Previous launch of Glonass satellites took place on October 26, 2007.

UPDATE 01/10/08: Information in the table updated to show internal Glonass numbers and the stations occupied by the satellites. Cosmos designations are still unknown.

UPDATE 02/11/08: Satellites received designations Cosmos-2434, Cosmos-2435, and Cosmos-2436.
