Blagovest satellites (technical identifier 14F149 ) form a constellation of four geostationary satellites to support Russian Armed Forces 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. [3]
The first satellite Kosmos 2520/Blagovest-11L was launched on 16 August 2017, [1] Kosmos 2526/Blagovest 12L on 18 April 2018, Kosmos 2533/Blagovest 13L on 21 December 2018, with the fourth (Kosmos 2539/Blagovest-14L) launched on 5 August 2019, using a Proton-M carrier rocket with Briz-M orbital insertion module. [4] [3] All launches took place from the Baikonur Cosmodrome Site 81 Pad 24. [5]
