NASA NEEDS RELIABLE, ACCURATE NAVIGATION FOR LAUNCH VEHICLES AND OTHER MISSIONS. GPS IS THE BEST WORLD-WIDE NAVIGATION SYSTEM, BUT OPERATES AT LOW POWER MAKING IT SUSCEPTIBLE TO INTENTIONAL AND UNINTENTIONAL INTERFERENCE. TOYON PROPOSES TO DEVELOP AN ANTI-JAM FRONT-END THAT USES SPACE-TIME ADAPTIVE PROCESSING TO SUPPRESS INTERFERENCE, AND IMPLEMENT IT IN A COMPACT, LOW-COST PACKAGE. THIS DESIGN WILL WORK WITH ANY EXISTING GPS RECEIVER, ALTHOUGH HIGHER PERFORMANCE CAN BE ACHIEVED BY TIGHTLY INTEGRATING A GPS RECEIVER MODULE WITH THE ANTI-JAM FUNCTIONALITY. TOYON'S MINIATURE INTEGRATED DIRECTION-FINDING ATTITUDE-DETERMINING ANTI-JAM SYSTEM (MIDAAS(TM)) OBTAINS POSITION, VELOCITY, ATTITUDE, AND TIME (PVAT) MEASUREMENTS DIRECTLY FROM GPS SIGNALS. THE ULTRA-TIGHTLY COUPLED (UTC) NAVIGATION ARCHITECTURE FUSES ALL SENSOR DATA. INTEGRATING THIS SYSTEM WITH THE ANTI-JAM MODULE MAKES THE SYSTEM INHERENTLY ROBUST TO INTERFERENCE AND THE RESULTING POSITION AND ATTITUDE ESTIMATE MORE ACCURATE.
