Chinese programme: CRESDA (China Center for Resources Satellite Data and Application) responsible of management and operations, CAST (Chinese Academy of Space Technology) of development.
The platforms are actively stabilised over 3 axes.
The design life time is 5 years.
The satellite exploits the sunsynchronous orbit of the DMC around 10:30.
Redundancy is implemented by co-flying with several other similar satellites in the DMC.
