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, provide jammer DOA information, and protect both GPS satellite and Pseudolite signals to be used in a military GPS receiver to provide Assured PNT solution. 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 and early part of Phase II 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 enhancement program Mayflower will build, test, deliver and demonstrate the GAJAS prototype system performance to meet the program objectives in a laboratory-controlled environment at Mayflower and at Army CERDEC, APG. The Phase III commercialization program will develop the form factor production representative GAJAS
