Today, unmanned aerial vehicles (UAVs) are no match for manned fighter pilots. US human pilots have shot down two of them this month alone. However, this could change. Speaking to Motherboard, the tech arm of Vice News, Dr. Todd Humphreys predicted that “UAVs will eventually achieve superiority” due to their ability to “pull G’s far […]

The rise of autonomous drones for commercial use promises new and exciting possibilities, but the threat of these drones being compromised by an attacker still looms. As more and more companies begin sending more and more drones into the skies, the question of security must be seriously examined.  According to Dr. Humphreys, commercial drones remain “very

Earlier this year, reports started to surface on Russian media of a strange phenomenon. In certain areas of central Moscow, mostly within sight of the Kremlin walls, satellite signals were scrambled. Instead of showing true locations, people’s phones were showing them almost 20 miles away at Vnukovo airport. Dr. Humphreys spoke with CNN about the

GPS World recently featured a paper authored by Dr. Humphreys and students from the Radionavigation Lab. The paper discusses the details of low-cost precise positioning, particularly in regards to autonomous driving. In order to achieve this level of precision, a dense reference network is required. The paper outlines the implementation of RNL’s own network, the

IEEE Spectrum recently featured an article discussing centimeter-accurate GPS positioning for automated driving. Dr. Todd Humphreys discussed why centimeter-accurate GPS positioning is necessary, as well as some of the challenges that have yet to be solved. “When there’s a standard deviation of 10 cm, the probability of slipping into next lane is low enough—meaning 1 part in a

A recent NBC News article on the threat of GPS jamming and spoofing featured comments and insight from Dr. Todd Humphreys. The article also cites some interesting cases of intentional GPS jamming in Europe and the UK. “The threat to the Global Positioning System (GPS) — the critical space-based navigational, positional and timing network —

Dr. Todd Humphreys recently co-authored an article on GPS spoofing defenses with Dr. Mark Psiaki. This article is the cover story of the August 2016 issue of IEEE Spectrum magazine. “Cellphone towers, stock exchanges, and the power grid all rely at least partly on GPS for precise timing. A well-coordinated spoof could interrupt communications, confuse

Austin, TX — Dr. Todd Humphreys and his students at the UT Radionavigation Lab recently demonstrated lane-departure warning system at the University of Texas at Austin campus deployed on a vehicle. “While it may only be a centimeter at a time, what a University of Texas at Austin professor and his team have been able

Austin, TX — Dr. Todd Humphreys and his students at the UT Radionavigation Lab have built an outdoor arena for testing automated drones as a part of the Machine Games project. KXAN News recently covered this story. “There is a lot to learn when it comes to the technology behind drones and how it could

The New Yorker featured an article on GPS: its importance in our lives and its vulnerability to spoofing attacks. Research related to GPS spoofing at the UT Radionavigation Lab was the center of attention in this write-up by Greg Milner. “The U.S. Department of Homeland Security classifies sixteen infrastructure sectors—including dams, agriculture, health care, emergency
