Blagovest satellites form a constellation of four geostationary satellites to support Russian military communications. The satellites have Ka and Q band transponders [1], and provide high speed internet, telephony, and other services.[2] They were manufactured by ISS Reshetnev, and are based on the Ekspress-2000 bus featuring two deployable solar arrays with five panels on each. The design life is 15 years.[1] The first satellite Kosmos 2520/Blagovest-11L was launched on 16 August 2017[2], Kosmos 2526/Blagovest 12L on 18 April 2018, Kosmos 2533/Blagovest 13L on 21 December 2018, with the fourth (Blagovest-14L) launched in April 2019, using a Proton-M carrier rocket with Briz-M orbital insertion module.[3][1] References1. ^1 [https://space.skyrocket.de/doc_sdat/blagovest-1.htm Blagovest 1, 2, 3, 4 (14F149)], Gunter’s Space Page, accessed 2019-01-17 2. ^1 [https://www.globalsecurity.org/space/world/russia/blagovest.htm 14F149 Blagovest communications satellite], Global Security, accessed 2019-01-17 3. ^1 Russia to Complete Military Satellite Constellation Blagovest in April, Sputnik News/Space Daily, 2019-01-15 3 : Communications satellites of Russia|Kosmos satellites|Satellites of Russia |
