MODELING & SIMULATION OF SMALL SATELLITE EHF COMMUNICATIONS

THE OBJECTIVE OF CCR'S PHASE I EFFORT IS TO PERFORM AN IN-DEPTH SURVEY OF RELEVANT ARCHITECTURAL DATA, TO IDENTIFY VIABLE APPROACHES AND SOLUTIONS, AND TO DEVELOP THE DESIGN FOR A PROTOTYPE MODELING AND SIMULATION TOOLSET TO ASSIST IN THE EVALUATION OF SMALL EHF COMMUNICATIONS ARCHITECTURES. ACCOMPLISHMENT OF THIS OBJECTIVE IS COMPLETION OF SEVEN TASKS: (1) ARCHITECTURE SURVEY; (2) REFINEMENT OF PROJECT SCOPE; 3) DEVELOPMENT OF DESIGN FOR EXTENDED SATELLITE SYSTEM MODEL TOOLSET; (4) DEVELOPMENT OF LIFE CYCLE COST MODEL; (5) INTEGRATED OF MODELS; (6) COLLATION AND EVALUATION OF RESULTSSS; AND (7) REPORTING. THIS EFFORT MUST CONCENTRATE ON THE DEFINITION OF A COMPUTER BASED MODEL, COMPLETE WITH DESCRIPTIONS OF ANTICIPATED CAPABILITIES AND LIMITATIONS, THAT CAN SIMULATE OPERATION OF THE FULL RANGE OF RELEVANT COMMUNICATION SCHEMES AND ARCHITECTURES, TO INCLUDE OUTPUTS SUCH AS EYE DIAGRAMS, BIT ERROR RATE, LINK BUDGETS AND ANTENNA COVERAGE LOCI IN EACH MODE. APPROPRIATE CONSIDERATION MUST BE GIVEN TO MODE (FDMA, TDMA, ETC.) DATA RATE, ERROR CORRECTION, JAM RESISTANCE, LPI AND LPD, UNIQUE OPERATIONAL NETWORKING, AND GROUND SEGMENT REQUIREMENTS. THE END RESULT WILL BE PRECVISE, RECOMMENDED SPECIFICATIONS FOR A SMALL SATELLITE NETWORK/ARCHITECTURE SIMULATION AND MODELING TOOLSET THAT INCORPORATES TECHNICAL AND COST EVALUATION PROCEDURES INHERENT TO OBJECTIVE PERFORMANCE ANALYSES AND EVALUATION OF RELEVANT CANDIDATE ARCHITECTURES.
