Detecting and Locating GPS Jamming

The Global Positioning System (GPS) has become a ubiquitous service supporting many critical infrastructures including intelligence and law enforcement missions, transportation, financial applications, civil safety response and Department of Defense capabilities. The GPS signal is susceptible to service outages due to intentional and unintentional jamming. Recognizing this threat, Exelis set out with the objective to develop technology that identifies and locates jamming sources. This technology provides actionable intelligence, enabling authorities to locate and mitigate the sources of interference thereby assuring safety, efficiency, and revenue. Our methodology includes combining sensors and proprietary software to enable geolocation of interference sources. The resultant data is available in the form of pin mapping of interference allowing the jamming source to be seen through an easy to use web enabled graphical user interface. The technology has the capability to locate disruptive sources utilizing a propriety algorithm. The system's sensors can be strategically located around high-risk areas, such as airports or utility grids, to instantaneously sense and triangulate the location of the jamming source. The server is able to identify the characteristic of the interference source and should a threat be detected and users will receive pin-point geolocation information in order to respond. The significance of this work is to protect military, commercial and industrial systems from a diverse range of threats.
