Okean-O1 spacecraft platform used by the Sich-1/Okean-O1-8 ocean-observation satellite.
Okean-O1 / Tselina-D-derived bus is the spacecraft platform associated with Sich-1, also named Okean-O1-8, an ocean-observation satellite. Sich-1 was the eighth Okean-O1 flight unit, with operational oceanography as its main mission.[1] The satellite had 1,950 kg launch mass and 300 W power, so this bus application is treated as a large platform.[1] The Okean-O1 platform carries Tselina-D-derived heritage.[2]
