Globus-1M #12L or No.12L (Russian: Глобус-1М meaning Globe-1M), also known as Raduga-1M 2 (Russian: Радуга-1М meaning Rainbow-1M) is a Russian military communications satellite which is operated by the Russian Space Forces. It was the second Raduga-1M satellite to be launched – the first being Globus-1M #11L which was launched in 2008, and forms part of the Raduga satellite system. It is positioned in geostationary orbit at a longitude of 70 degrees East.
Globus-1M #12L was built by JSC Information Satellite Systems, and is equipped with multiple transponders broadcasting centimetre-band and decimetre-band signals.[2] It was launched by the Khrunichev State Research and Production Space Centre, using a Proton-M carrier rocket with a Briz-M upper stage. The launch occurred at 00:18:00 GMT on 28 January 2010, from Site 81/24 at the Baikonur Cosmodrome.[3] The launch was successful, and inserted the satellite directly into geosynchronous orbit.[4] At launch the satellite had a mass of 2,500 kilograms (5,500 lb), with an expected operational lifespan of around 5 years.[5]
It is currently in a geostationary orbit, with an apogee of 35,788 kilometres (22,238 mi), a perigee of 35,784 kilometres (22,235 mi), zero degrees of inclination, and an orbital period of 24 hours.[5]
