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.
The Yaogan 30-01-01 to 30-01-03 (Remote Sensing Satellite-30-01-01 to 30-01-03) satellites, were launched by CZ-2C rocket from China's Xichang space center on 29 September 2017. The purpose is not confirmed, although the news reports hint towards a SIGINT mission, especially to detect ships by their radio emissions. They are also known as CX 5 by the manufacturer. The satellites are spaced by 120° in their orbit.
