Abstract: The ground simulation test evaluation was conducted for the small satellite and launch vehicle control systems transmitting data with CAN bus.Based on the two-stage bus network composed of CAN bus and Ethernet,the ground simulation test evaluation platform for satellite and launch vehicle control system was established,and the solutions for software and hardware of the bus nodes were proposed,and the analogue scheme for built-in test was designed.The simulation result shows that the signal of satellite control system,the operation of bus,the control cycle and network time delay can be appropriately analyzed with this platform.The research provides theoretic reference and technology support for the alternative evaluation,control and test study of the satellite and launch vehicle control systems.
