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. Demo Day is

September 2023: “Dr. Todd E. Humphreys, known for his fundamental contributions to secure, precise and robust PNT and GNSS software-defined receivers (SDR), received this year’s Johannes Kepler Award. The Institute of Navigation’s (ION) Satellite Division recognized Dr. Humphreys with this prestigious honor, the highest it bestows, during the ION GNSS+ 2023 conference in Denver.” For

September 2023: A paper written by the RNL’s Zach Clements titled “Dual-Satellite Geolocation of Terrestrial GNSS Jammers from Low Earth Orbit” got published in Inside GNSS. “In the past decade, there has been a sharp increase in GNSS outages due to deliberate GNSS jamming. Receivers in LEO are uniquely situated to detect, classify and geolocate

June 2023: RNL member Zach Clements, Todd Humphreys, and Patrick Ellis from Spire Global were awarded the Walter R. Fried Memorial Award for the best overall paper at the 2023 IEEE/ION PLANS conference. Their paper, titled “Dual-Satellite Geolocation of Terrestrial GNSS Jammers from Low Earth Orbit,” presents a comparison of a two-step geolocation method and
