Mission
Daqi-1 (AEMS)
- Type: Earth Science
- Orbit: Sun-Synchronous Orbit
China’s first satellite dedicated to comprehensive monitoring of the atmospheric environment, named Daqi-1, also known as Atmospheric Environment Monitoring Satellite (AEMS) and developed by the Shanghai Academy of Spaceflight Technology (SAST) in Shanghai, is designed to operate in sun-synchronous orbit. Daqi-1 can monitor fine particle pollution like PM2.5, pollutant gases including nitrogen dioxide, sulfur dioxide and ozone, as well as carbon dioxide concentration.
It combines both passive and active sensing, which can realize comprehensive monitoring of the atmospheric environment in a better way, according to a chief designer with SAST. The detection accuracy of fine particles and carbon dioxide column concentration by Daqi-1 has reached the international advanced level, the chief designer said. The atmospheric detection lidar deployed on the satellite is also the world's first that is capable of detecting both atmospheric aerosols and carbon dioxide.
Location
Launch Complex 9
Taiyuan Satellite Launch Center, People's Republic of China
Launch Complex 9 has witnessed the launch of 77 rockets, including 77 orbital launch attempts. While Taiyuan Satellite Launch Center, People's Republic of China, has been the site for 150 rocket launches.
The Taiyuan Satellite Launch Center is a People's Republic of China space and defense launch facility. It is situated in Kelan County, Xinzhou, Shanxi Province and is the second of four launch sites having been founded in March 1966 and coming into full operation in 1968.
Rocket
China Aerospace Science and Technology Corporation Long March 4C
The Long March 4C, also known as the Chang Zheng 4C, CZ-4C and LM-4C, previously designated Long March 4B-II, is a Chinese orbital carrier rocket. It is launched from the Jiuquan, Taiyuan Satellite Launch Centre and Xichangs, and consists of 3 stages. Long March 4C vehicles have been used to launch the Yaogan-1, Yaogan-3 SAR satellites and the Fengyun-3A polar orbiting meteorological satellite. On December 15, 2009 a Long March 4C was used to launch Yaogan 8.
Agency
China Aerospace Science and Technology Corporation
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.
