OKEAN – О1 Spacecraft (removed from service). / November 1, 2008 /

Tasks to be fulfilled:
Monitoring the Arctic and Antarctic ice conditions: mapping the boundaries of different thick ice floes; detecting large ice leads, areas of higher wind-driven waves resulted from hazardous natural phenomena; monitoring inland water bodies.

Consumers:
Federal and governmental services organizations (Rosgidromet, Minmorflot, and others) and consumers on vessels at sea as well
Special Features:
One spacecraft in orbit provides a full coverage of the entire Russian Arctic water surface with imagery data for 3-5 days .
