AKA: 11F629;4KT;Orion. Status: Operational 1971. First Launch: 1971-12-27. Last Launch: 1982-08-03. Number: 23 . Gross mass: 6,300 kg (13,800 lb).

It utilized the SA-106 topographic camera from the Krasnogorsk Mechanical Factory, and a laser altimeter and Doppler apparatus developed by NPO Radiopribor. The draft project was completed in 1968. Flight trials aboard the Soyuz launch vehicle began in 1971 from Plesetsk. Trials were completed in 1975 and the system was accepted into service in 1976. Launch vehicle was Soyuz 11A511M, the only spacecraft to use this launch vehicle. Typical orbital profile: inclination 82.3 degrees, 81.3 degrees with altitude of 215-245 km; inclination 72.8 degrees with altitude of 200-325 km; inclination 62.8 degrees with altitude of 230-275 km. Designed duration: 12 or 13 days. Transmission frequencies observed in West: 19.994 FSK.
