January 2025: Zach Clements is currently a PhD student in Aerospace Engineering at the University of Texas at Austin and a member of the Radionavigation Laboratory.  His research interests include statistical signal processing, optimal estimation, and software-defined radio, with an emphasis on GNSS interference detection, classification, and localization from Low Earth Orbit.  Before his graduate […]

UCCS Invitational Workshop on Space Cybersecurity and Resilience from Dec. 12, 2024.

November 2024: Some newer companies are exploring direct space-to-phone communication. These include SpaceX and AST SpaceMobile. “Sat phones have long been the gold standard for those needing connectivity in remote conditions. They are expensive to use, with rates normally running to dollars per minute. But they provide coverage in the middle of the ocean, up

November 2024: The Hudson Institute held an event with a panel discussion titled “Navigating GPS Vulnerabilities: Implications for US Economic and National Security.” During this panel, the RNL’s Dr. Humphreys gave a presentation on “Civil PNT Caught in the Crossfire.” For a transcript of the panel, visit their website here, and for a video of

October 2024: Dr. Humphreys attended the Brooklyn 6G Summit and gave a presentation on Day 2 titled “Bracing for Interference: Electronic Warfare and its Spillover Effects.” For a video of the presentation visit IEEE’s stream here, where Dr. Humphreys presentation starts around 4:19:00.

October 2024: The RNL’s Dr. Humphreys spoke at the Department of Transportation’s annual Civil GPS Service Interface Committee meeting on America’s susceptibility to GPS jamming and spoofing from space. Specifically, he says “there is every reason to believe China’s BeiDou global navigation satellite system has the ability to imitate American GPS signals and those of

September 2024: “Since the start of the Gaza war, the Israel Defense Forces (IDF) has been deploying a tactic known as GPS “spoofing”, designed to fool enemy missiles and rockets that rely on the global positioning system technology to aim at their target” reports the Australian Broadcasting Corporation (ABC). Their GPS spoofing has also affected

September 2024: As GPS jamming and spoofing continue, pilots, airlines, and officials voice their concerns. The WSJ reports that “[t]he number of flights affected daily has surged from a few dozen in February to more than 1,100 in August,” based on data from SkAI Data Services and Zurich University of Applied Sciences. While officials say

July 2024: As GPS service is threatened by spoofing and jamming, many modern day operations dependent on it are being threatened as well. As reported by the New York Times, in the last year over 60, 000 commercial aircraft have been victims of GPS spoofing. Our dependence on GPS and GNSS in general spans from

July 2024: GPS spoofing signals in the Eastern Mediterranean have reportedly been affecting areas in Lebanon, Israel, Syria, Jordan, Egypt, Turkey and Cyprus. These signals affect various operations, the most worrying being aviation. “Researchers from SkAI Data Services, using information from the OpenSky Network, detected almost 2,000 spoofed planes” over a recent 72-hour period.
