AN ANALYSIS TOOL HAS BEEN CREATED FOR THE MARS ASCENT VEHICLE AND WAS BUILT USING MATLAB/SIMULINK AND SIMSCAPE MULTIBODY. THE ENTIRE SIMSCAPE MODEL IS BROKEN UP INTO MANY DI_ERENT SUBSYSTEMS TO ENSURE THAT ANYONE WITH MILD UNDERSTANDING OF GUIDANCE CONTROL AND DYNAMICS CAN FOLLOW THE MODEL. THE OVERALL BLOCK DIAGRAM IS SHOWN BELOW WITH MANY COMMON SUBSYSTEMS SUCH AS THE GUIDANCE BLOCK AS WELL AS SENSOR FEEDBACK AND ACTUATOR DYNAMICS. THE PLANT DYNAMICS CONTAIN AS MANY MODELS AS POSSIBLE TO ENSURE THE SIMULATION IS AS HIGH _DELITY AS POSSIBLE WITHIN REASON FOR THIS 10 WEEK PROGRAM. THE PLANT CONTAINS THE FOLLOWING MODELS: AERODYNAMICS THRUST MASS STANDARD ATMOSPHERE AND GRAVITY MODELS. THE GUIDANCE BLOCK USES A TWO STAGE GUIDANCE LAW BASED ON A CHI TABLE TO ORIENT THE SPACECRAFT AND A BOUNDARY VALUE SOLUTION FOR THE SECOND STAGE. THE END RESULT IS A VISUALLY APPEALING AND EASY TO USE SOFTWARE FOR TRADE STUDIES AND SMALL MONTE CARLO SIMULATIONS.
