CTOnews.com March 26 news, the French National Aerospace Research Agency (CNES) for the Sino-French astronomical satellite (SVOM satellite, also known as space-based multi-band space variable source monitor) the flight parts of two French scientific payload instruments were shipped to the general assembly plant of the Micro Satellite Innovation Institute of the Chinese Academy of Sciences on March 16.

At this point, the Sino-French astronomical satellite prototype products are complete, and have entered the final assembly, integration and testing stage of the whole satellite. Karine, head of payload from French Space Agency, and his party arrived at the Microsatellite Innovation Institute of the Chinese Academy of Sciences on March 22. This is also the first time in more than three years that a team of French engineers has arrived at the Satellite Innovation Institute to work.

According to officials, engineers from China and France will work together in the next few months to complete the final assembly, integration and testing of SVOM satellite flying parts. This also marks the satellite officially entered the final joint AIT phase. It is reported that the SVOM satellite plans to complete the development and production plant by the end of 2023.

In addition, the Sino-French Astronomical Satellite (SVOM) scientific payload coded aperture   X-  imager and soft X-ray imager arrived in Shanghai from France on March 12. The SVOM satellite carried a total of four scientific instruments, two of which were developed by France and two by the Chinese side.

Gamma burst is the most violent explosion in the universe except the Big Bang, which involves many fields of astrophysics, from stars, galaxies to cosmology. In-depth observation and study of gamma bursts will help human beings to solve some major problems in basic science.

SVOM (Space Variable Objects Monitor) satellite is the most important gamma burst multi-band detection project after the American SWIFT mission, which has the functions and features of multi-band observation, fast maneuver, flexible operation and ground follow-up observation.

The satellite is approved by the National Space Administration of China and the French National Space Research Center, and developed by the Chinese Academy of Sciences. It will carry four equipment: an X-ray astronomical telescope (MXT), an X-ray and gamma-ray camera (ECLAIRs), a gamma burst monitor (GRM), and an optical telescope (VT).

The satellite has a working orbit of 635km x 30 °Leo, a design life of 3 years, a full weight of about 930kg and a heavy load of 450kg. It is scheduled to be launched by a long March 2C carrier rocket at the Xichang Satellite launch Center in 2023 to detect the most powerful phenomenon in the universe-gamma ray bursts.

China is responsible for the launch and operation of the satellite, while equipment and ground research are jointly carried out by China and France. It is reported that CNES is responsible for managing the French part of the project, excluding the human resources consumption of about 110 million euros (CTOnews.com Note: currently about 813 million yuan).

In fact, the Chinese and French governments signed the Agreement on Cooperation in Research and peaceful uses of Outer Space as early as 1997. CTOnews.com has reported that the French National Space Center has launched a Sino-French ocean satellite in 2018 in cooperation with the National Space Administration of China to study climate change by observing wind fields and waves on the ocean surface.
