VERIFICATION IN THE FINAL DESIGN PHASEWHAT TOOLS ARE REQUIRED (cont’d):IN A NEXT STEP GNC, MVM AND FDIR DESIGNS HAVE TO BE MERGED,TO ESTABLISH A FIRST PROTOTYPE OF AN RV ONBOARD CONTROLSOFTWARE.IT HAS THAN TO BE VERIFIED IN A CLOSED LOOP SIMULATION THATTHIS FIRST PROTOTYPE OF A RENDEZVOUS CONTROL SOFTWAREWILL WORK PROPERLY AND WILL PROVIDE THE REQUIREDPERFORMANCE IN THE ENVIRONMENT OF THE SIMULATED ONBOARDSYSTEM.FOR THIS PURPOSE THE SIMULATION MUST INCLUDE DETAILEDMODELS OF THE ONBOARD SYSTEM, i.e. OF• THE DATA MANAGEMENT AND COMMUNICATION ARCHITECTURE• THE ACTUAL DESIGN OF THE EQUIPMENT (SENSORS, THRUSTERS)(THIS IS IN CONTRAST TO THE GLOBAL BEHAVIOUR SIMULATION OF THEEQUIPMENT IN STEP 1)THIS SIMULATION IS STILL ALL S/W (NO H/W IN THE LOOP) AND DOESNOT NEED TO RUN IN ’REAL TIME’.Dr. W.
