The purpose of this review was to freeze the definition of all the « system » interfaces schematized by the arrows in Figure 2 and to begin to define the organization and content of the « system » tests. For example, the satellite reprogramming loop in case of an opportunity target request was discussed in detail. This review was addressed mainly to a group of French-Chinese experts, chosen for their expertise in the conduct of a space project (ground segment specialists, antennas network specialists …)
