Purple Mountain Observatory (PMO)

Established in 1928, was the first scientific research institution in China to carry out satellite and space debris observation, and is the base and operation unit of the Optical Observation Network of the Chinese Academy of Sciences. 

PMO houses four key laboratories of the Chinese Academy of Sciences: Radio Astronomy, Space Object and Debris Observation, Dark Matter and Space Astronomy, and Planetary Sciences, as well as two research centres of the Chinese Academy of Sciences – the Centre for Space Object and Debris Observation and Research, and the Centre for Antarctic Astronomy.  Its research in astrophysics and celestial mechanics is grouped into four divisions: dark matter and space astronomy, Antarctic astronomy and radio astronomy, applied celestial mechanics and space objects and debris, and planetary sciences and deep space exploration. Each division consists of research groups, observation stations, and laboratories, supported by a number of observations stations. 

This partnership aims to strengthen the research activities of the Centre for Space Object and Debris Observation and Research, as part of a large network spanning more than 20 countries.

International Scientific Optical Network (ISON) 

ISON is one of largest systems specializing in observation of space debris at high orbits and is capable of observing the whole GEO ring. 

ISON is coordinated by the Keldysh Institute of Applied Mathematics in Moscow and collaborates with optical observatories in countries including Russia, Ukraine (Andrushivka), Georgia (Abastumani), Uzbekistan, Tajikistan, Moldova, Spain (Teide), Switzerland (Zimmerwald), Bolivia (Tarija), Mongolia, USA (Mayhill) and Italy (Collepardo). These observatories are organised to detect, monitor and track objects in space.

EMPOSAT

Founded in 2016 and headquartered in Beijing, EMPOSAT has established more than a dozen branches in Xi'an, Zhengzhou, Zhongwei, Qitaihe, Jinghe, Hebi, the South Pacific, Africa, South America and other places. It is a comprehensive solution provider integrating commercial aerospace measurement, launch and control technology research and development, aerospace communication product manufacturing and spacecraft in-orbit operation and management services.

The company takes "making satellites better and easier to use" as its mission and is committed to building a global commercial space infrastructure, providing global space users with a package of solutions including rocket launch measurement and control, satellite measurement and operation control, payload data reception, remote sensing satellite calibration, space collision warning, space debris cleaning, space digital applications, and space science popularization services.

The company has won honorary titles such as National High-tech Enterprise, National Specialized and New "Little Giant" Enterprise, and Beijing's Top 100 Private Small and Medium Enterprises. At present, it has built a global satellite ground station network and comprehensive calibration field including more than 60 ground stations, and has served more than 370 satellites and rockets, taking a leading position in the field of domestic commercial aerospace measurement, transportation and control.
