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[2] It reportedly failed to return useful imagery due to an electrical malfunction.[3]
The satellites have a mass of 6,500 kilograms (14,000 lb), are 7 metres (23 ft) long, and 2.7 metres (8.9 ft) in diameter.
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 with a pixel size of 9 µm. The CCD is produced by ELAR, previously known as ELECTRON-OPTRONIC.[5] 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.
