SJ 18 [CCTV]
SJ 18 (Shijian 18) was a Chinese experimental geostationary satellite based on the new DFH-5 Bus.
SJ 18 was to be the maiden flight of the DFH-5 ultra-high-performance satellite platform, featuring a high-thrust ion propulsion. It provides payload power up to 28 Kilowatts.
The satellite hosted a Ka-band high-throughput communications payload of 70 Gbps. Also an optical infrared laser communications terminal for downlinks with data rates of upt to 4.8 Gbit/s was on board. Reportedly an experimental quantum communications payload, similar to the one on QSS (Mozi), was also carried.
The satellite was launched in June 2017 on a CZ-5 rocket from the Wengchang cosmodrome, but failed to reach orbit.
