Cosmos 2477

NSSDCA/COSPAR ID: 2011-064B

Description

Cosmos 2477, a Glonass-M Russian navigation satellite, was launched from Baikonur on 04 November 2011 at 12:51 UT by a Proton-M rocket. Cosmos 2477, which launched along with two other Glonass-M satellites, will join the Glonass constellation of 27 satellites. The constellation includes 23 which are used for their designated purpose, while one is in the phase of joining to the system, two are out of operation for technical maintenance, and one is in orbital reserve. The constellation is spread among three orbital planes, each designed to contain eight satellites to maximize coverage around the world. At least 18 working satellites are needed for the GLONASS system navigation signal to be received continuously all over Russian territory, while for global purposes there needs to be 24.
