SATELLITE SURVIVABILITY METHODOLOGY DEVELOPMENT

A METHODOLOGY FOR EVALUATING SATELLITE SYSTEM SURVIVABILITY (AS A FUNCTION OF CONTROL AUTONOMY) IS PROPOSED. THE METHODOLOGY COMBINES THE PROVEN EFFECTIVENESS OF ANALYSIS AND SIMULATION TECHNIQUES FOR ASSESSING JAMMING, NUCLEAR SCINTILLATION AND PHYSICAL THREATS UNDER CONTROL AND GUIDANCE OF AN EXPERT SYSTEM. THE KEY TO THIS PROPOSED CONCEPT IS THE APPLICATION OF INNOVATIVE LINKAGE TECHNIQUES TO ALLOW A SINGLE, EASILY-MANIPULATED, NETWORK DESCRIPTION FILE TO DRIVE MULTIPLE EVALUATION PROCEDURES/TECHNIQUES IN A SINGLE COORDINATED SUPPORT PACKAGE. TO GUIDE THE ANALYST IN CREATING THE CONTROL OPTIONSFILES AND IDENTIFYING POTENTIALLY ROBUST SYSTEM AUTONOMY OPTIONS, ARTIFICAL INTELLIGENCE TECHNIQUES WILL BE STUDIES TO PROVIDE THE FILE EDITOR. THE RESULTANT AUTONOMY EXPERT SYSTEM PLAYS THE ROLE OF AN EXPERT ADVISOR TO THE ANALYST AND INSTRUCTS HIM IN THE USE OF THE MULTIPLE EVALUATION TECHNIQUES. THIS CONCEPT WOULD PROVIDE AN ANALYSIS APPROACH SPECIFICALLY TAILORED TO THE GENERATION OF TECHNICAL PERFORMANCE MEASURES FOR QUANTIFYING THE COMPLEX RELATIONSHIP AMONGST AUTONOMY, GROUND SUPPORT, CONTROL DECENTRALIZATION, MISSION PERFORMANCE AND SURVIVABILITY. THE APPROACH IS FULLY GENERALIZED AND WILL ALLOW ONE TO EVALUATE THE ANTICIPATED SURVIVABILITY AND PERFORMANCE LEVELS OF ANY CANDIDATE SATELLITE NETWORK CONTROL STRUCTURE.
