ABSTRACT: Qunav proposes to develop a Multi-element Anti-jam reconfigurable GPS Navigation Technology (MAGNT) that will enable state-of-the-art electronic protection (EP) by integrating space-time adaptive processing (STAP) into a signal processing part of a reconfigurable GPS receiver. MAGNT will result in an improved STAP solution that provides the maximum protection against emitters while minimizing distortions in pseudorange and carrier phase measurements and can be implemented in a real-time operational prototype. Unique features of the improved STAP solution include: 1) Ability to utilize various STAP implementations without redesigning the antenna electronics: STAP functionality is reconfigurable by modifying the receiver"s reprogrammable hardware (supported by field programmable gate arrays) and embedded software modules. 2) Combined pre and post-correlation characterization of emitters: Our improved STAP solution combines the traditionally used pre-correlation approach with a novel post-correlation threat detection via multi-directional beam-steering. STAP is optimized to suppress emitter signals found at pre-correlation and post-correlation stages thus enabling EP capabilities for conventional threats, as well as spoofing, meaconing and emerging threats. 3) Dynamically-reconfigurable anti-jamming solution that adapts to changing radio-frequency environments by on-the-fly selection of the STAP implementation option, which optimizes the ability to operate under a specific jamming scenario while mitigating code and carrier phase measurement biases. BENEFIT: MAGNT has a significant potential for both DOD applications and the private sector. Numerous platforms (both military and civilian) have a need for multi-element GPS processing to enable EP and high-sensitivity signal detection and tracking. The technology will be useful for enabling robust functionality in various emitter environments, as well as for indoor, urban, and foliage canopy applications where GPS traditionally has difficulty operating. For DOD applications, MAGNT will be mostly beneficial for precision navigation applications that require robust carrier phase measurements with electronic protection such as Joint Precision Approach and Landing System (JPALS) and Automated Aerial Refueling (AAR). For these applications, the optimal transitioning strategy includes a technology spiral insertion designed to add new MAGNT capabilities to existing navigation systems. From the prospective of private sector, the largest commercialization potential can be achieved if the MAGNT is combined with a multi-platform high-sensitivity signal processing and then applied for the market of consumer devices.
