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.
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.
The third satellite, Kosmos 2506, was successfully launched on June 23rd, 2015. 
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 CCD sensor is probably ELCT1080v1U with a pixel size of 9 μm. The CCD is produced by ELAR, previously known as ELECTRON-OPTRONIC.[failed verification] The focal plane unit is manufactured by NPO Opteks.
