How Vulnerable is GPS?
The New Yorker feature "How Vulnerable is GPS?" discusses WNCG professor Todd Humphreys' journey uncovering and demonstrating security weaknesses in the Global Positioning System.
Humphreys is a pioneer in the the study of Global Navigation Satellite Systems. His research group was the first to demonstrate cm-accurate RTK positioning through a smartphone antenna, and in 2012 they demonstrated the first successful spoofing of UAVs. Since then, Humphreys has examined real-world instances of spoofing and jamming that raise serious concerns about the ubiquitous technology.
"'We’re seeing a general consensus that GPS is wonderful, but we’ve got to cut our habit,' Humphreys told [The New Yorker]. The signature precision of the system seems to be giving way to blurry, unnerving chaos. But what might a viable alternative look like?"

Dr. Humphreys specializes in the application of optimal detection and estimation techniques to problems in satellite navigation and communication, autonomous systems, and signal processing. His recent focus has been on assured perception for autonomous systems, including navigation, timing, and collision avoidance, and on low-Earth-orbiting satellite mega-constellations. Besides being director of WNCG, Dr.
