GU-1 Earth Observation CubeSat Series

550 km Sun-synchronous orbit

GU-1 Earth Observation CubeSat Series

Six satellites placed in orbit since 2021, supplying agricultural and disaster monitoring data.

The GU-1 series are 6U Earth-observation satellites carrying a 3.2 m resolution optical payload. The satellites make about 15 orbits a day in a 550 km Sun-synchronous orbit.

Achievements

  • Six satellites, 21,000 orbits in total
  • 1.8 million km² imaged; 14 km swath
  • Processing software that performs cloud masking and change detection on board

Use

Images are used by agricultural cooperatives, disaster management and municipalities. In the 2025 flood disaster, maps of the affected areas were provided within 36 hours.
