AKA: Sich-1. Status: Operational 1986. First Launch: 1986-07-28. Last Launch: 2004-12-24. Number: 9 . Gross mass: 1,950 kg (4,290 lb).

Oceanographic research satellite, developed by KB-3 at NPO Yuzhnoye in the Ukraine, Vladimir Iosifovich Dranvoskiy, Chief Designer. The Okean oceanographic research satellite, later called Sich-1 by the Ukrainians, weighed 1950 kg, of which 505 kg was scientific instruments. Development was authorized on 5 May 1977 as one of the third generation of Soviet space systems. It was equipped with:

• SUOS pointing, orientation, and stabilization system including:
  • Korall-A6 radio-command command-programming-trajectory system
  • BR-91Ts radiotelemetry system
  • STR thermoregulation system
  • SEP electrical feed system
• SM-5 magnetometer
• RFA radiophysical instrument with:
  • RLSBO side-looking radar with a swath width of 450 km and a resolution of 1.3 x 2.6 km
  • RM-0.8 scanning radiometer with a swath width of 550 km and a resolution of 25 km
• RTBK radio-television complex with:
  • MSU-M 4-band multispectral scanner with a swath width of 1900 km and a resolution of 1.8 km
  • MSU-S 2-band multispectral scanner with a swath width of 1100 km and a resolution of 410 m
• Kondor-2 system for interrogation, acquisition, storage, and dumping of data from Kondor-1 earth ground stations
