Persona is a class of Russian reconnaissance satellites, derived from the Resurs DK class of remote sensing satellite, itself derived from the Soviet Yantar reconnaissance satellites. The satellites are built by TsSKB-Progress, and the optics by LOMO and the Vavilov State Optical Institute.
The first satellite, identified as Kosmos 2441, was launched into a 750 km sun synchronous orbit on 26 July 2008, atop a Soyuz-2.1b carrier rocket from LC-43/4 at the Plesetsk Cosmodrome[1] It reportedly failed to return useful imagery due to an electrical malfunction.[2]
A second satellite, Kosmos 2486, was launched on 7 June 2013.[3]
The satellites have a mass of 6,500 kilograms (14,300 lb), are 7 metres (23 ft) long, and 2.7 metres (8.9 ft) in diameter. [citation needed]
The satellites optical subsystems are believed to be based on a 3-mirror Korsch type telescope with a primary mirror diameter of 1.5 metres (4.9 ft) and focal length of 20 metres (66 ft).[4]
The CCD sensor is probably ELCT1080v1U[citation needed] with a pixel size of 9 µm.[5] The CCD is produced by ELAR, previously known as ELECTRON-OPTRONIC.[6] The focal plane unit is manufactured by NPO Opteks.
The satellites have a nadir image resolution of 33 centimetres (13 in), using panchromatic imagery. They are planned to operate for 7 years.[citation needed]
