Research Institution
Current anti Jam GPS antennas are approximately 14" in diameter making them too large for several platforms of interest such as unmanned aerial vehicles, missiles and fighter aircrafts. A modified version of this antenna array is significantly smaller in size (seven inch diameter) but incorporates only 4 antenna elements, thus, limiting its nulling capabilities under severe jamming conditions. To alleviate these limitations, Applied EM is proposing a miniature GPS antenna that would allow for anti-jamming capability (with 5 to 7 elements) to acquire accurate PVT (Position, Velocity and Time) in a hostile RFI (Radio Frequency Interference) environment. This will improve GPS reliability for situation awareness in battlefield scenarios and will further make GPS a viable solution for precision approach and landing. A second focus of our proposal is to enhance the antenna electronics using -time adaptive processing (STAP) or space-frequency adaptive processing (SFAP) with optimum performance.
