Hardware-in-the-loop validated simulation platform for small satellite control system

The system constitution and project design of the hardware-in-loop validated simulation platform of small satellite control system were introduced and the real time satellite control simulation was carried out.Taking the dSPACE real-time simulator as a keystone of platform,the simulation was accomplished successfully on an air-bearing table with on-board computers,sensors and actuators.Using this platform,the function and electric interfaces of some absent equipments were simulated absdutely.So hardware-in-the-loop validated simulation of the satellite control system can be completed in time,which saves time or cost.The platform sufficiently considers the satellite space environment during the simulation and enhances the simulation reliability.It is an efficient and convenient tool for satellite hardware-in-loop simulation.
