DIGITAL ACCELERATION SENSORS FOR INERTIAL GUIDANCE OF SMART MUNITIONS

AN INERTIAL GUIDANCE SYSTEM FOR SMART MUNITIONS USING SAW RESONATOR BASED ACCELERATION SENSORS IS PROPOSED. THE ADVANTAGES ARE LARGE DYNAMIC RANGE, TEMPERATURE COMPENSATION, 12 BIT ACCURACY, AND A DIGITAL OUTPUT WITHOUT ANALOG-TO-DIGITAL CONVERSION, SMALL SIZE, AND LOW COST. STUDIES HAVE SHOWN INTEGRATED ERROR RATES LESS THAN 1 NAUTICAL MILE/HOUR CAN BE ACHIEVED. THESE ADVANTAGES ENABLE THE SAW SENSOR TO MEET ALL OF THE REQUIREMENTS OF INERTIAL ACCELERATION SENSORS FOR SMART MUNITIONS. THE PROPOSED PHASE I STUDY WILL PROVIDE A DETAILED DESIGN STUDY OF SAW SENSORS AND A BASELINE INERTIAL SYSTEM WILL BE SIMULATED TO VERIFY THE SYSTEM PERFORMANCE IN TERMS OF SMART MUNITIONS INERTIAL REQUIREMENTS. HARDWARE IMPLEMENTATION AND TESTING WILL BE PERFORMED IN PHASE II OF THE PROJECT.
