Persona is a class of Russian reconnaissance satellites, derived from the Resurs DK class of remote sensing satellite, in turn 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.

Satellite
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. It reportedly failed to return useful imagery due to an electrical malfunction.
A second satellite, Kosmos 2486, was launched on 7 June 2013 and after some initial technical problems, it was apparently operational in Summer 2014.
The third satellite, Kosmos 2506, was successfully launched on June 23rd, 2015.
Details
The satellites had a mass of 6,500 kilograms (14,300 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).
The CCD sensor is probably ELCT1080v1U with a pixel size of 9 µm. The CCD is produced by ELAR, previously known as ELECTRON-OPTRONIC. The focal plane unit is manufactured by NPO Opteks.
The satellites had a nadir image resolution of 33 centimetres (13 in), using panchromatic imagery. They are planned to operate for seven years.
