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.

Work from Radionavigation Lab Featured in InsideGNSS

Research done by WNCG alum Matthew Murrian was featured on the cover of the InsideGNSS January/February 2020 volume. Murrian, the lead author on the paper, conducted the work along with Lakshay Narula and Radionavigation Lab director Prof. Todd Humphreys.

Todd Humphreys Elected Institute of Navigation 2020 Fellow

WNCG professor Todd Humphreys has received the Institute of Navigation’s (ION) “highest honor.” Humphreys was elected to the membership rank of Fellow at ION’s International Technical Meeting in January. He is one of only three recipients of the honor for 2020.

Humphreys’ election cited his “significant and fundamental contributions to PNT security and precise GNSS positioning for the mass market, and for dedication to GNSS education and outreach.”

A Phase-Reconstruction Technique for Low-Power Centimeter-Accurate Mobile Positioning

Recent technological advances in embedded systems have enabled designers of Global Navigation Satellite System (GNSS) receivers to produce ever smaller, cheaper, and more energy-efficient devices. However, despite these advancements, the underlying positioning accuracy of consumer-grade GNSS receivers (such as those in smartphones and tablets) has somewhat stagnated. The most notable advances in positioning accuracy have been occurring in non-consumer, industrial-grade receivers, for example, in receivers designed for agriculture and surveying purposes.
