Shijian-18

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 high-thrust ion propulsion. It provides a payload power of up to 28 Kilowatts. The satellite hosted a Ka-band of 70 Gbps heigh-throughput communications payload. Additionally, an optical infrared laser communications terminal for downlinks with data rates of up to 4.8 Gbit/s was on board. Reportedly an experimental quantum communications payload, similar to the one on QSS (Mozi), was also carried.
