Navigation Warfare Compatible Small GPS User Equipment (SGUE)

ABSTRACT: The objective of this SBIR program is to develop a highly integrated Military GPS User Equipment that can provide accurate and robust position, navigation and timing (PNT) capability to size, weight, power, and cost (SWaP-C) sensitive military users operating in the emerging navigation warfare (NAVWAR) environment. In the emerging NAVWAR scenarios, the GPS receiver should be capable of mitigating the jamming threats from the enemy forces (Red Force Electronic Attack) as well as from the friendly forces (Blue Force Electronic Attack or BFEA) and provide situation awareness of the RF environment. The MGUE hence need to be capable of seamless integration with Electronic Protection (EP) and Electronic Support (ES) subsystems. We define SGUE to be the MGUE optimized for integration with NAVWAR ES/EP in a small form factor. In the Phase I of this SBIR program, Mayflower developed an integrated ES/EP/SGUE system architecture to meet the Air Force objective of providing robust PNT solution to the SWaP-C constrained platforms in NAVWAR environment. Mayflower proposes to leverage its expertise in developing SWAP-C optimized GPS Receiver, Anti-Jam and Electronic Support subsystems to demonstrate the integrated ES/EP/SGUE system architecture in Phase II which will lead to developing ASICs to meet the final program objective. The ES/EP/SGUE system architecture will be implemented and demonstrated on an FPGA/general-purpose microprocessor based prototype platform. BENEFIT: The proposed research and development will result in highly SWaP-C optimized integrated ES/EP/SGUE technology for use in Navigation Warfare environments, suitable for deployment in the handheld Soldier radios, munitions and small UAVs. Some aspects of this technology are applicable to commercial GPS as well as other GNSS (Galileo and GLONASS) users namely, airlines, to protect, detect and characterize unintentional and intentional interference sources.
