GPS EMitter LOCalization (GEMLOC)

In response to DHS SBIR Topic H-SB013.1-004 we propose to investigate the development of a next-generation, tiered, inexpensive, light-weight, low-power, high-performance GPS emitter detection and localization system. The system will provide high-accuracy (high-sensitivity), real-time or near-real-time estimates of position, velocity, transmit frequency, and transmit power level of multiple, moving, low-power emitters in the GPS L bands (L1, L2, and L5). It will work with existing deployed GPS equipment. Reporting of events will make use of existing technology, if applicable. At the end of Phase I, we plan to have a solid understand of GPS vulnerabilities understanding of GPS dependencies and vulnerabilities in the Energy, Communications, and Transportation Sectors and a prototype design for a GPS emitter detection, localization, and reporting system for these three sectors. At the end of Phase II, we anticipate having a much deeper understanding of GPS dependencies and vulnerabilities in these sector plus the Emergency Services Sector. We plan to deploy a prototype GPS emitter detection, localization, and reporting system. We also plan to carry out a demonstration of the capability at NAVFEST or a suitable test environment. Today, the TRL is 3 and we expect it to be TRL 5 or 6 by the end of the Phase-II contract.
