SBIR-STTR Award

In response to DHS SBIR Topic H-SB013.1-004 we propose to investigate the development of a next-generation, tiered, inexpensive, light-weight, lowpower, high-performance GPS emitter detection and localization system. The system will provide high-accuracy (high-sensitivity), real-time or nearreal- 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.

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.
