February 2020: The Radionavigation Lab’s work in GNSS interference detection was featured on the cover of Inside GNSS, a magazine dedicated to global navigation systems. Click here to read the article from Inside GNSS. In 2017, the Radionavigation lab placed a custom software defined receiver onboard the International Space Station as part of a larger effort […]

February 2020: The Institute of Navigation presented awards at their International Technical Meeting in January. These recipients are affiliated with the Radionavigation Laboratory: Dr. Zaher (Zak) Kassas (left) is a former member of the lab and current professor at the University of California, Irvine.

February 2020: The Army Futures Command (AFC) has partnered with the University of Texas at Austin to develop robots to assist with dangerous tasks on the battlefield. These robots will assist with non-combat jobs such as minesweeping and obstacle removal. This partnership has enabled the construction of a new robotics center at UT Austin. “It’s

January 2020: Dr. Todd Humphreys was interviewed by Fortune Magazine for his investigation of GPS spoofing and interference in the shipping industry. Read the Fortune article here.

January 2020: Key infrastructure of the United States, including cell-phone networks, financial markets, the electric grid, and emergency services, all depend on GPS timing signals for basic operation. A large-scale, coordinated attack could be accomplished by only a dozen or so people with the right equipment, spread out across the country. “There is no foolproof defense,” Humphreys

December 2019: Researchers at the Center for Advanced Defense Studies (C4ADS), a nonprofit that analyzes global conflict and security issues, have published evidence suggesting that GPS signal spoofing is behind maritime AIS (automatic identification system) disruptions in Shanghai. Data aggregated over many weeks showed ship locations appearing at different locations in large “rings: on the eastern bank

December 2020: Dr. Todd Humphreys has been investigating spoofing in Shanghai for quite some time. In this article for Inside GNSS, Humphreys offers a detailed analysis of ship positioning data and insight as to what’s going on in Shanghai.

November 2020: Dr. Peter Iannucci presented to the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board at their semi-annual board meeting on November 20, 2019. His presentation, titled “Augmenting GPS with PNT from LEO”, is available online. “The National Space-Based PNT Advisory Board provides independent advice to the U.S. government on GPS-related policy, planning, program management, and funding profiles in

October 2019: The Army Futures Command (AFC) has named the University of Texas Radionavigation Lab (RNL) and Applied Research Laboratories (ARL) as its strategic partners in assured positioning, navigation, and timing (PNT). Interviewed by GPS World, Dr. Humphreys revealed that RNL’s main focus will be “… leveraging the tens of thousands of communications satellites projected

July 2019: For weeks, a mysterious source of GPS interference has been affecting aircraft in the Middle East. Since last spring, pilots flying through airspace around Syria have noted that their GPS systems have displayed the wrong location or even stopped working entirely. A few weeks ago, the issue spread to Israeli airspace when pilots started
