Research of a construction method of space-based cyber-physical system

Cyber-physical systems (CPS) are integrations of computation and physical processes. For space environment, this paper proposes space-based cyber-physical systems (SCPS), which are intelligent systems that can satisfy the rising demand for space exploration. Compared with traditional satellite system, SCPS can be built with lower cost, shorter development cycle and can accomplish diverse tasks. In order to build SCPS, Sandroid architecture and Sandroid satellite are introduced. And the network construction of SCPS is described. Sandroid satellite is a kind of CubeSat uses Android as operating system and smartphone chips as control unit. In SCPS, Sandroid satellites collaborate with each other to accomplish complex task. So a new method for the collaboration among Sandroid satellites is presented.
