Key techniques of on-orbit service-oriented reconfigurable cellularized satellite and its prospects

In order to cope with the various challenges of the traditional spacecraft design mode, outstanding problems such as the insufficiency of the technical status and the satellite morphology are analyzed. For the representative idea of 'Phoenix Rising', satellite cellularization for on-orbit assembly are described in this paper and the connotation and design principle of the reconfigurable cellularized satellites are presented. In the face of the challenges for on-orbit assembly tasks, the key techniques of the cellularized satellites such as architecture optimization, information fusion, control for multicellular architecture and precise teleoperation are summarized. Finally, outstanding issues for the future research on cellularized satellites are summarized and the research prospects are proposed based on the technical status of China.
