The optical Earth observation satellite Sich-3-O will obtain super-resolution digital panchromatic and multispectral images of the Earth surface.
The satellite is capable of area and strip mapping and stereo imaging in one orbit.
An ammonia propulsion system in the satellite supports orbital correction maneuvers.
