GLOBAL POSITIONING SATELLITE TRANSPONDER

WE WILL DESIGN, DEVELOP AND DELIEVER PROTOTYPES OF A TRANSPONDER WHICH USES GLOBAL POSITIONING SATELLITE (GPS) DATA TO SELF TO SELF-LOCATE A TEST VEHICLE ON A RANGE OR ELSEWHERE. OUR DESIGN WILL BE BASED ON INTEGRATION OF CURRENT AND PROJECTED STATE-OF-ART SYSTEMS FROM DOMESTIC SUPPLIERS SUCH AS MOTEROLA, MAGNAVOX, ROCKWELL, STANDFORD TELECOMMUNICATIONS AND WILL RELAY THE NAVIGATION MESSAGE TO ONE OR MORE GROUND SITES FOR TRACKING OF POSITION DATA. OUR PHASE I STUDY WILL PROVIDE A REVIEW OF AVAILABLE HARDWARE AND PLATFORM TRADES ON THE PRINCIPAL DESIGN ISSUES OF GPS ACCURACY VERSUS SIZE/COMPLEXITY, FREQUENCY BAND FOR TRANSPONDING CONSIDERING RFI, ANTENNA SIZE, ALLOCATION AVAILABILITY, AND DATALINK STRATEGIES TO ACCOMIDATE MULTIPLE FURNISHED UNITSIN REAL TIME.
