FAA Updates GPS GNSS Interference Guide to Address Jamming and Spoofing
The FAA released Version 1.1 of its GPS GNSS Interference Guide, detailing jamming, spoofing risks, global hotspots, and pilot mitigation procedures.
This article is based on an official press release from National Business Aviation Association (NBAA).
The Federal Aviation Administration (FAA) has issued a significantly updated resource guide to help the aviation industry combat the growing threats of GPS and Global Navigation Satellite System (GNSS) interference. The newly released Version 1.1 of the guide provides critical information on jamming and spoofing trends, their impacts on aircraft systems, and recommended procedures for pilots and operators.
According to a recent press release from the National Business Aviation Association (NBAA), the updated document reflects extensive input from industry stakeholders. This includes recommendations from the Performance Based Operations Rulemaking Committee’s (PARC) GPS/GNSS Disruption Action Team, of which the NBAA is an active member.
As satellite navigation becomes increasingly foundational to global airspace operations, the proliferation of intentional and unintentional signal disruption poses a significant safety challenge. The FAA’s revised guide aims to equip flight crews, operators, and avionics manufacturers with the latest mitigation strategies and training recommendations.
Key Updates and Industry Collaboration
Focus Areas and Revisions
The FAA’s Version 1.1 guide is a heavy revision of an edition published earlier this year. It incorporates refined guidance on how flight crews should respond to degraded or manipulated satellite signals. The NBAA noted in its release that the updates are designed to be actionable for a broad spectrum of the aviation community, from frontline pilots to equipment manufacturers.
“NBAA recognizes the problems with GPS interference and potential for interference around the world and is taking action to ensure users of the National Airspace System are informed. This guide is not just a resource for pilots; it also provides information for operators and avionics manufacturers. Because this version is so significantly revised, stakeholders familiar with the previous version should review the new guide and implement recommendations appropriate to their operation.”
This statement was provided by Richard Boll, chair of the NBAA’s Airspace and Flight Technologies Subcommittee, in the organization’s official announcement.
Global Hotspots and Domestic Risks
High-Risk Regions for Spoofing
While GPS interference can occur anywhere, the FAA guide identifies several global hotspots where spoofing, the intentional broadcasting of false signals to deceive receivers, is particularly prevalent. According to the NBAA summary, the top impacted areas include the Eastern Mediterranean Sea, the Black Sea, Russia and the Baltic Region, the India/Pakistan Border, Iraq and Iran, North and South Korea, and areas surrounding Beijing, China.
Unintentional Domestic Interference
The threat is not limited to international conflict zones. The NBAA release highlights that unintentional widespread GPS interference has also occurred within the United States. Faulty commercial equipment or inadvertent signal rebroadcasting from avionics repair shops can block or disrupt GNSS reception in localized areas.
The organization pointed to a notable incident in 2022, where multiple aircraft experienced unreliable GNSS signals near Denver International Airport (DEN). The disruption, which affected civilian flights and air traffic control systems, was ultimately traced to an unauthorized transmitter broadcasting on a GNSS frequency.
Reporting and Mitigation
The Importance of Pilot Reports
To effectively track and mitigate these disruptions, regulatory bodies rely heavily on accurate data from the flight deck. The NBAA is urging operators to provide detailed descriptions of any interference events, including the specific equipment affected, the mitigation actions taken by the crew, and any subsequent maintenance procedures.
“It is critical that pilots and operators report any suspected GPS/GNSS interference, jamming and spoofing incidents to the FAA. The FAA and other agencies take these reports seriously.”
Boll emphasized this point in the NBAA statement, reinforcing the need for a proactive reporting culture across the industry.
AirPro News analysis
At AirPro News, we observe that the rapid escalation of GPS spoofing and jamming incidents over the past few years has transformed a niche technical issue into a primary operational hazard for global aviation. As malicious actors utilize increasingly sophisticated technology to manipulate satellite signals, the reliance on GNSS for primary navigation and surveillance creates a vulnerability that regulators are racing to address. The FAA’s rapid iteration of its resource guide underscores the urgency of the threat. Moving forward, we anticipate the industry will need to accelerate the development and certification of alternative positioning, navigation, and timing (A-PNT) systems to ensure resilient operations in contested airspace.
Frequently Asked Questions
What is the difference between GPS jamming and spoofing?
Jamming involves overpowering a GPS signal with noise, causing receivers to lose their connection. Spoofing is a more insidious attack where false signals are broadcast to deceive a receiver into calculating an incorrect position or time.
Where can pilots find the updated FAA guide?
The GPS and GNSS Interference Resource Guide Version 1.1 is available through the FAA and is highlighted in the NBAA’s official communications and resources.

FAA Completes Phase One of NOTAM System Cloud Modernization
The FAA finished phase one of the NOTAM system upgrade, migrating to cloud infrastructure to improve safety and reliability ahead of schedule.
The Federal Aviation Administration (FAA) has successfully completed the first phase of a major overhaul to its critical pilot alert system, moving the decades-old infrastructure to the cloud. According to an official press release from the FAA, U.S. Transportation Secretary Sean P. Duffy announced the milestone on May 12, 2026, noting that the project was finished more than a year ahead of its original schedule.
The modernized system, known as Notices to Airmen (NOTAM), is essential for commercial and general aviation. It provides pilots with real-time safety information, including runway closures, airspace restrictions, and potential hazards. The upgrade aims to prevent the kind of nationwide airspace shutdowns that have previously crippled U.S. air travel, while enhancing overall safety and communication reliability.
By transitioning the NOTAM system to a cloud-based architecture in April 2026, the Department of Transportation and the FAA hope to future-proof the nation’s aviation infrastructure. The rapid deployment was achieved through an innovative vendor challenge designed to bypass traditional bureaucratic delays, culminating in a partnership with IT contractor CGI Federal.
Accelerating the NOTAM Modernization
The legacy NOTAM system, which processes more than 4 million alerts annually, had long been a vulnerability in the National Airspace System. Its fragility was most notably exposed in January 2023, when a complete system failure forced a nationwide ground stop, halting thousands of flights and stranding passengers across the country.
Following that incident, initial projections from the previous administration estimated that a full modernization would not be completed until late 2027. However, the current Department of Transportation prioritized the overhaul to mitigate the risk of future collapses, accelerating the timeline significantly.
“The last administration handed us a 40-year old aviation alert system on the verge of complete collapse,” U.S. Transportation Secretary Sean P. Duffy stated in the FAA press release. “Instead of waiting for another nationwide ground stop, we moved at the Speed of Trump to build a brand new, modern system, and we did it years ahead of schedule.”
Technological Upgrades and Industry Impact
The successful completion of Phase One involved migrating the core NOTAM infrastructure into a secure cloud environment. This shift is expected to provide greater redundancy and scalability, ensuring that the system can handle the high volume of critical alerts without buckling under pressure.
The FAA collaborated with CGI Federal to develop the new service, utilizing a streamlined procurement process to accelerate the timeline. The agency also engaged directly with aviation stakeholders, including pilots, dispatchers, and flight planners, to ensure the modernized system meets the practical needs of its end users.
“Our transition to this state-of-the-art NOTAM system strengthens safety and reliability across the National Airspace System,” FAA Administrator Bryan Bedford noted in the official announcement. “We are focused on building a modern aviation system for the future, one that is resilient, efficient, and capable of meeting the demands of the world’s busiest airspace.”
AirPro News analysis
The accelerated timeline for the NOTAM overhaul reflects a broader push by the current Department of Transportation to expedite infrastructure projects through non-traditional procurement methods. By utilizing a “vendor challenge” rather than a standard multi-year bidding process, the FAA was able to rapidly deploy CGI Federal’s cloud solution.
While Phase One represents a significant technical milestone, the true test of the modernized NOTAM system will be its operational stability during peak travel seasons and severe weather events. Furthermore, the transition of the entire system remains ongoing. We will be watching closely to see if subsequent phases can maintain this accelerated pace without compromising the rigorous safety standards required for the National Airspace System.
Frequently Asked Questions
What is the NOTAM system?
The Notices to Airmen (NOTAM) system is a critical aviation alert network that communicates temporary changes, such as runway closures, airspace restrictions, and obstructions, to pilots and flight planners. Over 4 million NOTAMs are issued every year.
Why was the NOTAM system overhauled?
The legacy system was decades old and prone to technical failures. In January 2023, a complete shutdown of the NOTAM system led to a nationwide grounding of flights. The overhaul aims to move the infrastructure to the cloud to improve reliability and prevent future outages.
Who developed the new NOTAM system?
The Federal Aviation Administration (FAA) collaborated with CGI Federal to develop the modernized cloud-based service, utilizing a streamlined vendor challenge to accelerate the project.
