This Phase I SBIR program will define and architect on all-digital, Anti-Jam, Wide-Bandwidth, Open Architecture GPS Receiver (AJ-WOAGR) for detailed design and implementation during Phase II SBIR activities. The receiver design will focus on a flexible, open architecture design that can be used both as a developmental tool and as a stepping stone toward new generation of high density, low-cost GPS receivers with the appropriate mix of capabilities. As a development tool, the AJ-WOAGR will provide an open architecture for the analysis, test and demonstration of the new link-military (Lm) signal performance, the performance of various GPS jamming and spoofing techniques, the definition and performance analysis of various temporal, multi-antenna spatial, and combined temporal-spatial anti-jam techniques, and the detction, direction-fidning (DF) and geolocation of inadvertent or intentional GPS jammers and spoofers. Follow-on developments will allow the appropriate mixture of open-architecture components to be reduced using MCM, ASIC, and novel packaging technologies to small , high-density, low-cost components and entire receivers for both the military and commercial marketplace.
