Kosmos 2457 (Russian: Космос 2457 meaning Cosmos 2457) is one of a set of three Russian military satellites launched in 2009 as part of the GLONASS satellite navigation system. It was launched with Kosmos 2456 and Kosmos 2458.
This satellite is a GLONASS-M satellite, also known as Uragan-M, and is numbered Uragan-M No. 733.[1][4]
Kosmos 2456/7/8 were launched from Site 81/24 at Baikonur Cosmodrome in Kazakhstan. A Proton-M carrier rocket with a Blok DM upper stage was used to perform the launch which took place at 10:38 UTC on 14 December 2009. The launch successfully placed the satellites into Medium Earth orbit. It subsequently received its Kosmos designation, and the international designator 2009-070B. The United States Space Command assigned it the Satellite Catalog Numbers 36112.[1][4]
It is in the first orbital plane of the GLONASS constellation, in orbital slot 6. It started operations on 24 January 2010.[5][6]
