The semi-physical simulation system design of micro-satellite based-on HLA

The ground simulation validation is an important process during small satellite's development. Giving consideration to the characteristics of small satellite and a type of ground simulation requirements, a small satellite hardware-in-loop simulation system based-on HLA is established. System structure, the interaction data table, hardware interface unit and the federal members’ flow chart are designed. The simulation and validation are done to a certain small satellite through the designed hardware-in-loop simulation system. The results show that the simulation system is able to simulate dynamics and control subsystem, power supply subsystem and payload subsystem and realize accessing physical equipment of control subsystem much better, and has good practical application value.
