Abstract: Our Phase II effort in response to DHS SBIR Topic H-SB013.1-004 we propose to investigate the development of a next-generation, ground- and air-based, tiered, inexpensive, 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 (10 mW) emitters in the GPS L bands (L1, L2, and L5). It will work in conjunction with deployed GPS equipment and possibly Govt-issue smartphones to provide additional measurements of GPS emitters.. The system will quickly and accurately detect and localize GPS threats to critical infrastructure, including jamming, spoofing, advanced adaptive and cognitive threats, and natural threats such as solar radio bursts and scintillations. The tiered system consists of ground- and air-based sensor nodes, deployed GPS equipment, smartphones, and a centralized processing capability. The new sensors will use TDOA/FDOA and angle-of-arrival technology to precisely localize GPS jammers and spoofers, including less precise but higher density smartphone data. The specific product to be developed is a GPS emitter detection and localization system that can be deployed locally or over a region. The product will be available to DHS, FAA, FCC and many DoD and IC agencies. Commercial value is in transitioning the technology into the GPS test and simulation markets. A smartphone- and web-based service will report GPS outages and events. Today, the TRL is 3 and we expect it to be TRL 5 or 6 by the end of the Phase-II contract.
