M.Eng. Project Announcement – 2012-2013
Project title: GPS Jammer Localization
Brief description of project goals:
Overview:
GPS and other Global Navigation Satellite System (GNSS) Position, Navigation, and Timing (PNT) services have become ubiquitous utilities. Beyond its obvious navigation use in cell phones, cars, ships, and aircraft, GPS is used for timing in cell-phone towers, in the electric power grid, in the financial industry, and in other parts of the our civilian infrastructure. Unfortunately, these signals are vulnerable to disruption via intentional or un-intentional jamming. A jamming attack adds too much noise to the GPS band, thereby causing a receiver to lose lock on the signal and cease returning navigation data. The GPS group at Cornell University has significant experience in designing and fabricating real-time software radio receivers for GPS signals. It is building on this experience to address issues of GPS signal availability and integrity. One of these efforts seeks to thwart jamming attacks by quickly detecting jammers, determining their locations, and alerting authorities who can interdict them.
Specific M. Eng. Contribution:
This project involves the development of estimation strategies and algorithms to detect and track jammers and to use tracking observables to geolocate jammers. The geolocation problem involves the use of signals from the receivers of a spatially distributed network. Jammer data has been collected from a special DHS-sponsored test at White Sands Missile Range. The M.Eng. project will focus on analyzing that data with the goal of developing effective tracking algorithms for various types of jammer signals and of developing geolocation algorithms that can rapidly pin-point jammers that have been detected and tracked by a network of receivers. Time and progress permitting, some of the developed algorithms may be implements in real-time jammer detection software radio receivers.
