The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
Shijian 18 is a Chinese experimental geostationary satellite based on the new DFH-5 Bus. Reportedly the transmission capacity of the satellite is double that of current Chinese communications satellites, allowing more television channels and clearer programs to be transmitted. The new satellite will also improve internet connectivity and accessibility as well as reduce users' costs.
