On December 26, 2004 Russia successfully launched Proton-K rocket from the Baykonur launch site. The launch was performed from the launch pad No. 23 of the launch site No. 81 at 16:53 MSK (13:53 UTC). The rocket, equipped with DM-2 upper stage, successfully deployed three GLONASS navigation satellites – Cosmos-2411, Cosmos-2412, and Cosmos-2413. The total number of operational GLONASS satellites in the constellation to 14.
The Space Forces reported that the satellites reached their intended orbits at 20:38 MSK (17:38 UTC). The orbits are semi-synchronous circular with altitude of 19137 km and the inclination of 64.8 degrees. All satellites were launched into the first orbital plane of the constellation. According to the Glonass Information Center of the Ministry of Defense, the satellites have internal numbers 712 (Cosmos-2411), 796 (Cosmos-2413), and 797 (Cosmos-2412) and they will be deployed at points 7, 1, and 8 respectively. This will complete deployment of satellites in the first plane (points 2 to 6 have been filled already). The international designations and NORAD catalog assigned to satellites are: Cosmos-2411 - 2004-053B/28509, Cosmos-2412 - 2004-053C/28510, and Cosmos-2413 - 2004-053A/28508 [information on designations was updated on February 10, 2005].
One of the satellites – Cosmos-2411/GLONASS-712 – is the second satellite of the Glonass-M type. These satellites are expected to have longer lifetime than their predecessors. The first satellites of this type – Cosmos-2404/GLONASS-701 – was launched in December 2003 and after a period of tests was accepted for service on 12 October 2004.
