The Double Star mission consists of two spacecraft to study the Sun-Earth connection in tandem with the Cluster mission
The Double Star mission
ANNALES GEOPHYSICAE, no. 8 (2005): 2707-2712
The Double Star Programme (DSP) was first proposed by China in March, 1997 at the Fragrant Hill Workshop on Space Science, Beijing, organized by the Chinese Academy of Science. It is the first mission in collaboration between China and ESA. The mission is made of two spacecraft to investigate the magnetospheric global processes and their ...更多

- The history of scientific collaboration between China and ESA began in 1980 through the signing of a document that facilitates the exchange of information between ESA and the
Commission for Science and Technology of China
- The spacecraft and ground segment operations are performed by the Double Star Programme (DSP) Operations and Management Centre (DOMC) and DSP Scientific Operations Centre (DSOC) in China, using three ground station, in Beijing, Shanghai and Villafranca
- DOMC checks the commands of the payload, generate bit streams and send them to Xian Satellite Control Center (XSCC) for up-linking to S/C and execution
- The Double Star mission consists of two spacecraft to study the Sun-Earth connection in tandem with the Cluster mission
- Six-point measurements of the main plasma parameters are performed in the key scientific regions of the near-Earth environment
- The coupling between the smallscale processes and the evolution of large-scale structures can be investigated. This joint mission will prepare for the future multi-point missions that will be necessary to understand and later on, be able to predict the effects of the Sun and solar wind on the Earth environment

European DSP data centers: 3
Next, the Chinese DSP Data Center with help of Chinese instrument groups processes the data and produces the standard DSP data products for Chinese instruments (Fig. 4). The three European DSP data centers (Austrian, French and UK ) with help of European PIs process the raw data to produce the standard DSP data products and send them to the other data centres, with an exception that the NUADU data processing is executed in Beijing. After that, Chinese DSP Data Center will exchange the standard DSP data products with the Austrian DSP Data Center that distributes them to the European scientists
