How Vulnerable is GPS?

Aug. 13, 2020
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.
