Past Symposiums 2014



Dr. Todd E. Humphreys is an Assistant Professor of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin, and director of its Radionavigation Lab. Humphreys, a Cornell alum, received his PhD in 2008 under advisor Prof. Psiaki.  He specializes in the application of optimal estimation techniques to problems in satellite navigation, orbital and attitude dynamics, and signal processing. He directs the Radionavigation Laboratory at UT-Austin, where software-defined GPS receivers are developed as a platform for GPS technology innovation and study of the ionosphere and neutral atmosphere. His recent focus has been on defending against intentional GPS spoofing and jamming. In 2008 he co-founded Coherent Navigation, a startup that hardens GPS by, among other things, exploiting telephony signals from the Iridium satellite constellation. Learn more about him and his research herehere, and here.

Keynote Talk

The next few decades will see pervasive autonomous control systems become critical to the world economy—from autonomous cars and aircraft to smart homes, smart cities, and vast energy, communication, and financial networks controlled at multiple scales. Protecting these systems from malicious attacks is a matter of urgent societal interest. The study of secure control has made important advances over the past few years, but these constitute not solutions so much as problem framing and an emerging consensus that traditional fault detection and mitigation fails when confronted with a deliberate attacker: outlaws are different from outliers; fraud is different from faults. Moreover, the vast majority of this early literature focuses only on cyber attacks—infiltration of the communications networks over which sensor measurements y and control commands u are conveyed.
