Persona (satellite)

Persona is a new class of Russian reconnaissance satellites. It is derived from the Resurs DK class of remote sensing satellite, itself derived from the Soviet Yantar reconnaissance satellite. The satellites are built by TsSKB Progress, and the optics by LOMO and Vavilov Institute.

The first satellite 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 at the Plesetsk Cosmodrome [http://www.spaceflightnow.com/news/n0807/26soyuz/]

Satellite mass is 6500 kg, length is 7 meters and diameter is 2.7 meters.

Optical subsystem is probably based on a 3-mirror Korsch type telescope with primary mirror diameter of 1.5 meters and focal length of 20 meters. [http://lomo-tech.ru/photos/lomo_kosm_otkr.pdf] Diffraction pattern of this telescope indicate that pixel size of TDI CCD senzor is 12 µm or 6 µm. CCD manufacturer is ELECTRON-OPTRONIC (now is a ELAR [http://www.npp-elar.ru/tdi.html] ). Focal plane unit manufacturer is NPO Opteks.

Image resolution (at nadir) is 0.4 meter panchromatic.

Planned mission duration is 7 years.
