Gaofen 3 02



The Gaofen-3 satellites are based on the CS-L3000B bus, built for a lifetime of up to eight years. They are equipped with a Synthetic Aperture Radar (SAR) and a data transmission system and utilize Control Moment Gyros (CMGs) for orientation in space.

The Gaofen 3 series are built and developed by the China Academy of Space Technology (CAST), which is part of the China Aerospace Science and Technology Corporation (CASC). They are the main spacecraft production and development center of China and were involved in the launch of the country’s first successful artificial satellite, Dong Fang Hong I.

This satellite is part of the Chinese High-resolution Earth Observation System (CHEOS) program, which was proposed in 2006 and initiated in 2010 with the goal to improve and update China’s Earth observation system.
