Shijian 17



Shijian 17 is a technology experimental satellite designed and built by China Academy of Space Technology (CAST). Despite claims that the satellite was based on the DFH-4S satellite bus, it appears that Shijian 17 is based on an improved DFH-3B satellite bus, which has also been used by the LaoSat 1 telecommunications satellite launched in 2015.

Operating from Geostationary Earth Orbit (GEO), Shijian 17 was designed to demonstrate a variety of new technologies, including spacecraft propulsion, solar array cells, guidance, navigation and control (GNC), and space-based optical observation of space debris.
