GPS Anti-Jam Antenna System (GAJAS) for Pseudolites and Blue Force Electronic Attack Interference Sources

Mayflower proposes a suite of innovative interference mitigation techniques to build a complete GPS anti-jam antenna system GAJAS (including both antenna array and antenna processing unit) that can overcome not only the co-site interference from pseudolites and BFEA transmissions but also the hostile jammers. The techniques involve time domain, frequency domain, as well as spatial domain approaches. These techniques are combined in GAJAS in a coherent fashion to form a complete solution to the various interference problems. In Phase I of this program, Mayflower has analyzed the feasibility of proposed GAJAS system to meet the challenging signal processing requirements imposed by collocated GPS pseudolites and BFEA signals while mitigating hostile jammers in a size, weight and power (SWaP) efficient form factor. In the Phase II program Mayflower will build and demonstrate this GAJAS prototype system performance to meet the program objectives in a laboratory-controlled environment at Mayflower and at Army CERDEC, APG. The Phase II.5/III commercialization program will develop the form factor production representative GAJAS product, flight test it on selected Army platforms and fully qualify it.
