Abstract: The purpose of Hardware-In-Loop-Simulation (HILS) is to verify the hardware interface of On-Board- Computer (OBC) with flight sensors and actuators and to validate the closed loop performance of attitude and control elements (AOCE) for various control modes in real-time. This document presents distributed computingconfiguration of computing elements that interact mutually to achieve the real-time performance of hardware-in-loop simulation. The system architecture proposed is used successfully toaccomplish the real time closed loop performance for HILS. By distribution of resources, we can achieve thecomplex computationrequirements of spacecraft dynamics simulation, telemetry (TM), telecommand (TC) and star simulation with optimized delay.
