GPS JLOC Sensor Suite for Critical Infrastructure

Timing and position data from civil GPS receivers have become integral to the operation of many of the Nation's critical infrastructures. Through the Patriot Watch architecture, DHS is coordinating efforts to identify, locate, and attribute domestic GPS interference, maintain a central database for reports of domestic and international interference to civil use of GPS and its augmentations, and notify departments and agencies of GPS interference. Under this SBIR effort we shall survey existing use of GPS in critical infrastructure within the energy and financial sector. Based on our prior experience working with the Air Force on the vulnerability of civil GPS receivers, we shall highlight leverage points of the critical infrastructure that could vulnerable to a GPS cyber attack. Using this analysis we shall develop requirements for GPS jammer or spoofer detection and localization features that could be used to protect critical infrastructure from GPS cyber attacks. We shall develop a design for a Phase II SDR sensor system, compatible with the existing JLOC Server in use as part of the Patriot watch architecture that can be used to protect against the threats identified from our survey results. In the final report we shall document the proposed Phase II test plan and the design of the planned JLOC sensor network that will be field tested and assessed for reliability and effectiveness at detecting, reporting and providing the timely localization of GPS disruptive events under the Phase II effort. Analysis of the expected JLOC sensor performance will be provided (TRL 3).
