Kosmos 2481 (Russian: Космос 2481 meaning Cosmos 2481) is a Russian Strela-3 military communications satellite which was launched in 2012 by the Russian Aerospace Defence Forces. It was launched with 2 Gonets-M civilian communication satellites and a research satellite called Yubileiny-2, also known as MiR.

Launch

Kosmos 2481 was launched from Site 133/3 at Plesetsk Cosmodrome in northern Russia. It was launched by a Rockot carrier rocket with a Briz-KM upper stage at 01:35 UTC on 28 July 2012.[2][3] The launch successfully placed the satellite into low earth orbit. It subsequently received its Kosmos designation, and the international designator 2012-041A. The United States Space Command assigned it the Satellite Catalog Number 38733.[2][3]

The Russian military announced that the rocket was under control of the Titov Main Test and Space Systems Control Centre at 01:38 UTC and the satellites were released from the rocket at 03:19 UTC.[2][4]

It was the first launch of a Rockot since February 2011 when a satellite was placed in the wrong orbit due to a problem with the upper stage.[5][6]

Strela-3

Kosmos 2481 is a Strela-3 satellite. They are described as store-dump communications satellites which receive information from the ground when they pass overhead, and store that information until they pass over the ground station they deliver the information to.[7]:{{{3}}} The satellites are in low earth orbit going round the earth every 116 minutes.[2][8] A full deployment of Strela-3 craft should consist of twelve satellites.[7]:{{{3}}} The satellite has the GRAU index 17F13, showing it is a Strela-3, not a Strela-3M (also called Rodnik) as they have a GRAU index of 17F132.[1][3][9]

Strela-3 has a civilian variant called Gonets which is used by the Russian government for communication in remote areas. It can take between two minutes and six hours to deliver messages.[4]

The previous satellites of this class, Kosmos 2467 and Kosmos 2468, were launched together on 8 September 2010.[9]
