Miniature Anti-Jam GPS Nulling Utility Mode (MAGNUM)
ABSTRACT: GPS is known to be extremely vulnerable to signal interference, both unintentional and deliberate. Military navigation systems for air, sea, and ground vehicles require reliable GPS performance to provide navigation capability. Some type of GPS jamming signal mitigation technique is needed beyond conventional filter methods since these interference signals are in the GPS bands and therefore cannot be removed with traditional in-band filtering. Consequently, a cancellation method that preserves the GPS signals while eliminating the undesired interference is needed. Antenna nulling methods are a common solution for mitigating jammer signals from GPS, however many existing military platforms have limited space and power requirements that do not allow for traditional antenna nulling/beam-steering anti-jam solutions requiring considerable power and size. A SWaP optimized GPS AJ solution is required that can protect GPS on handheld radios, manpack radios, highly space-constrained UAVs, and munitions. The proposed Miniature Anti-Jam GPS Nulling Utility Module (MAGNUM) ASIC solution will leverage existing mature Mayflower ASIC technology and proven Small Antenna System (SAS) architecture into a single AJ ASIC that can be integrated into next generation military GPS receivers, or directly into a small CRPA array to support extremely space/cost constrained platforms. BENEFIT: The proposed Mayflower Miniature Anti-Jam GPS Nulling Utility Module (MAGNUM) ASIC will be a practical interference mitigation solution that offers significant benefits to improving GPS performance in hostile environments where anti-jam systems were never before possible on extremely space-constrained vehicles with limited budgets. The MAGNUM ASIC can be used in all commercial GPS receivers that need some kind of radio frequency interference (RFI) protection. The commercial market size is very large.
