Kosmos 2479 was launched from Site 81/24 at Baikonur Cosmodrome in Kazakhstan. The last[4][6][7] Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 05:49 UTC on 30 March 2012. The launch successfully placed the satellite into geostationary orbit.[2] It subsequently received its Kosmos designation, and the international designator 2012-012A.[4] The United States Space Command assigned it the Satellite Catalog Number 38101.[5]
Kosmos 2479 replaced Kosmos 2440 which was launched in June 2008 and operated until February 2010.[2] These satellites are moved to 80°E and then moved to their intended position.[2] It arrived at 80°E in mid-April 2012 and featured in the official opening of the Oko eastern control centre at Pivan-1 in May.[8][9] It started to drift from 80°E in July 2012 and in October 2012 it was stabilised at 166°E, a location registered as Prognoz-6 but which had previously never been used.[8][10][11]
