January 2024: “Parts of Poland, Lithuania, southern Sweden, and other countries in the Baltic region had an unexpected Christmas present this year. GPS signals were disrupted and not available in many areas on the 25th and 26th of December […] Analyses of the event by graduate students at the University of Texas Radionavigation Laboratory and […]

January 2024: Airway UM688 has been the likely unintentional target of multiple GPS spoofing events. These events manifest as “suddenly, either the plane will start to turn or you’ll get a whole bunch of warnings: terrain failure, navigation error, position error.” The RNL’s Dr. Todd Humphreys believes that these sort of events are “here to

December 2023: Reports of GPS spoofing in commercial aircraft centered near the Middle East have been increasing since September of 2023. According to the RNL’s Zach Clements, “theresearch community has long warned the public about something like this.” In fact, the RNL’s Dr. Todd Humphreys displayed the possibility by spoofing a luxury yacht in the

December 2023: GPS spoofing of aircraft has continued in the Middle East, “corrupting their backup inertial navigation systems (INS).” The RNL’s Dr. Todd Humphreys along with Zach Clements are using GNSS observables obtained from LEO satellites to geolocate the spoofers. According to Dr. Humphreys, “the device was on the eastern periphery of Tehran based on

November 2023: RNL alumnus Dr. Zak Kassas has been elevated to IEEE Fellow! Here is the list of Fellows elevated in 2024. Congratulations to Dr. Kassas!

November 2023: The first cases of GPS spoofing of commercial aircraft occurring in the last couple of months. OPSGROUP, an international group of pilots and flight technicians, “has tracked more than 50 incidents in the last five weeks.” According to the RNL’s Dr. Humphreys,“spoofing is the new jamming. In other words, it is being used for denial

November 2023: GPS spoofing events are becoming increasingly common. “Jamming is common in conflict zones. Spoofing, until recently, was rare. In the Middle East, Professor Humphrey’s research team found widespread spoofing with false signals telling pilots that their aircraft were directly above the airport in Tel Aviv when they were far away.” Visit the article here for

October 2023: Two recent articles from Politico featured comments from Dr. Todd Humphreys and Zach Clements related to their work from the “Dual-Satellite Geolocation of Terrestrial GNSS Jammers from Low Earth Orbit” paper, as well as more recent observations. Dr. Humphreys stated that their recent observations are ” the most sustained and clear indication of

October 2023: A recent Haartz news article on Israel’s GPS jamming efforts counteracting Hezbollah and Hamas drone attacks featured information revealed in Zach Clements’s “Dual-Satellite Geolocation of Terrestrial GNSS Jammers from Low Earth Orbit” paper. Their article provides context for the findings based on local circumstances. The original article can be found here, with a

October 2023: Locus Lock, founded by RNL alumna Hailey Nichols, was selected as one of the startups for the Fall cohort of the Techstars Space Accelerator. The selected teams “are going after big ideas in aerospace, including rapid launch services, precision-based imaging, operating systems for complex robotics, in-space servicing, and thermal protection.
