Three Glonass-M spacecraft Cosmos 2456 (Glonass 730), Cosmos 2457 (Glonass 733) and Cosmos 2458 (Glonass 734) were added to the Russian global navigation satellite system. They were launched by a Proton-M rocket with a Block DM upper stage from Baikonur on 14 December 2009 at 10:38 UT. The spacecraft are designed to last seven years. The constellation currently has 19 active satellites which enable continuous coverage of the entire Russian territory. Global service requires 24 active satellites.
