Summary
GAOFEN-4, also known as Gao Fen 4, is an Earth observation satellite launched on December 28, 2015, from Xichang Satellite Launch Center using a Chang Zheng 3B launch vehicle. Operated by CNSAS (China National Space Administration), the spacecraft measures 5 meters in length and has a diameter of 2.5 meters with a span of 30 meters, indicating large solar arrays or antennas. It was built on the DFH-4 bus by CAST (Chinese Academy of Space Technology) and has a dry mass of 2500 kg, launching at a mass of 5000 kg. The satellite is powered by two deployable solar arrays and batteries and is designed to last for 8 years in its mission to conduct Earth observation tasks. It features a box shape with two panels, suggesting the presence of solar arrays or other equipment extending from the main body.
