NBAA alerts on GPS interference risk-why now, what is available to defend and what tech may be available soon

As expected, NBAA has issued the below informative message about the current level of threat of GPS INTERFERENCE (spoofing, jamming or other interference). Mr. Bolen’s message is extremely timely based on the following experts’ analysis:

GPS jamming and spoofing have clearly increased since the U.S./Israel attack on Iran, with the most intense effects observed in:

• • • • • • • The Strait of Hormuz
            • The Persian Gulf
            • The Gulf of Oman
            • The UAE
            • During the first two days of the Israel–Iran war, GPS jamming incidents surged
            • Jamming has persisted throughout the conflict, disrupting commercial flight
            • Increased spoofing/jamming in the region raises risks for:
              • RNAV/RNP procedures
              • ADS‑B positional integrity
              • GNSS‑dependent avionics
            • Airlines have already been rerouting or increasing reliance on inertial systems in hotspots.

 

The pattern matches Iran’s known electronic warfare doctrine and has already produced measurable operational impacts. [the degree of this attack’s pervasiveness and distorting is that Residents in Dubai and the UAE reported phones showing impossible locations (e.g., cars appearing in the sea).

Graph demonstrates the geographical bounds of the current threat—

This horrendous attack on civil aviation has been a known phenomenon for a while and is not contained in the Middle East. A sampling of past posts on this subject will add some context to jam/spam:

• • • • PNT as an important response to Jamming and Spoofing 7/24
      • GPS Spoofing: Final Report Ops Work9/24
      • OpsGroup Cites 500% Increase in GPS Spoofing, Recommends NaviGuard to Detect Inflight Spoofing Alerts 9/24
      • An antidote to GPS spoofing- can FAA authorize using it NOW!!! 10/24
      • Administrator Bedford: a way to respond QUICKLY to jamming and spoofing THREATS 2/26
      • Spoofing: A Clear And Present Danger For Airlines 2/26
      • FAA Jamming and/or spoofing GNSS INTERFERENCE resource guide 2026
      • 

NBAA is working hard to assure that all industry-wide amelioration strategies includes its members’ operation. That effort includes receiving early information about the current tactics and about the locus of risks.

 

The current extent of the FAA’s strategy is procedural/not technology to use these steps i to minimize interference is as follows:

• • • RAIM / A‑RAIM
    • Multi sensor navigation (DME/DME, IRS)
    • Pilot procedures for GNSS loss
    • NOTAM based awareness of interference zones

A technology advance (GNSS) created an enhancement of SAFETY and unfortunately, the GPS system had a weakness allowing malevolent actors to introduce a profoundly serious threat of harm. A search of possible certificated hardware antidotes to this interference found this one– ready for installation:

The only publicly documented certificated (i.e., STC approved) civil aviation solution so far is the Aerodata AG GPS Antijamming & AntiSpoofing System, certified by EASA for installation on the Cessna Citation Latitude with Garmin G5000 avionics. [Inside GNSS Aerodata AG]

And there are prophylactic systems that are in the process of approval:

• • • Multi GNSS + multifrequency receivers (L1/L5/E1/E5)
    • Advanced spoofing resistant receivers (vector tracking, signal authentication)
    • Aviation grade inertial + GNSS fusion with spoofing detection
    • Space based authentication (e.g., GPS M code is military only; Galileo OSNMA is still maturing)

In light of the effectiveness of and pervasiveness of the IRANIAN INTERFERENCE, HOPEFULLY the FAA, EASA and other CAAs will place greater resources to approve this essential tools for aviation safety. Some might see this as a heavy allocation for resources of a temporary conflict, the past record of these terrorist acts has not been confined to this zone. Further, it is likely that those who have develop this destructive technology can and will share it with their nefarious allies.

GPS Interference: A Worldwide Threat to a Global Industry

March/April 2026

By Ed Bolen, President and CEO

Business aviation, which has always been a global industry, becomes more so with each passing year, as demonstrated by data showing a continuing uptick in missions with an international profile.

While this trend is a welcome development for companies seeking opportunities beyond U.S. borders, it has not been without some troubling elements, including a spike in reported incidents of GPS spoofing, jamming, or other interference.

In fact, according to research by OPSGROUP and others, these events have been rising not only in frequency, but in the number of affected hot-spot locations outside the U.S. We see this not just in the data, but in the anecdotal evidence regularly emerging in the alerts and other warning flags from air navigation service providers globally.

“We’re working from several angles to DEVELOP MITIGATION STRATEGIES, INCLUDING THROUGH REPRESENTATION IN GOVERNMENT-INDUSTRY WORKING GROUPS FOCUSED ON HOW GPS INTERFERENCE IS IMPACTING OPERATORS, WHICH SPECIFIC SYSTEMS ARE AFFECTED AND HOW FLIGHT CREWS ARE RESPONDING TO REAL-WORLD SCENARIOS.”

NBAA shares our members’ concern over this serious threat to safety and security. We’re working from several angles to develop mitigation strategies, including through representation in government-industry working groups focused on how GPS interference is impacting operators, which specific systems are affected and how flight crews are responding to real-world scenarios.

That advocacy work not only ensures the industry’s voice is heard regarding threats from GPS interference; it directly informs NBAA’s guidance for members’ day-to-day mission planning.

For example, NBAA’s dedicated conferences – including those for international operators, maintenance technicians, and scheduler/dispatchers – have brought together top experts to highlight the latest data, best practices, and protective technologies in connection with GPS interference. The association’s website and dedicated NBAA News Hour webinars also offer actionable information, accessible any time, on GPS spoofing and jamming.

NBAA’s work to help the industry harden itself from GPS interference illustrates a larger point: as business aviation’s growing global footprint leads to increasing mission complexity, you can count on the association to help you navigate the challenges to your operations, in the U.S. and around the world.
