Abstract
In this paper, according to the task requirement that the satellite control system is capable of accepting the replacement and expansion of the on-orbit module, the control system architecture of the data network based on the time trigger mode is studied. In this paper, a distributed architecture and a satellite control system with a component as an Orbital Replacement Unit (ORU) on-orbit are proposed, which makes the satellite control system more standardized and more reconfigurable and expandable while accepting on-orbit services. This paper analyses the key technologies of the satellite control system to achieve acceptable on-orbit services, and designs a demonstration and verification scheme to verify the timing scheduling strategy of the control system based on TTEthernet, the design of communication protocol, and the system reconstruction strategy after plug and play of intelligent nodes.
