OKEAN 1 Spacecraft (removed from service)

Mission Objective
Spacecraft is designed for an operational and all-weather acquisition of data on the ocean surface conditions.

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.

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 .
