The Study and Implenentation of the Real-Time Interfaces in Spacecraft''s Hardware-In-The-Loop Simulation System

This paper concerns with real-time interface techniques in the spacecraft'shardware-in-the-loop simulation system.At first,the constitution of spacecraft's hardware-in-the-loopsimulation system is introduced.Then,the hardware and software design techniques of real-time interfaceare discussed and the design of connecting the data acquisition computers and data handle computers withEthernet is forwarded.Finally, the reliability of spacecraft's hardware-in-the-loop simulation system isstudied.
