The Federal Aviation Administration (FAA) has revised its guidance on GPS/GNSS interference, jamming, and spoofing, incorporating recommendations from a joint government and industry rulemaking committee.

According to the National Business Aviation Association (NBAA), the updated GPS and Global Navigation Satellite System (GNSS) Interference Resource Guide Version 1.1 reflects significant revisions since its December release. These updates include input from the Performance-Based Operations Rulemaking Committee (PARC) GPS/GNSS Disruption Action Team, alongside FAA-led enhancements.

The revised guide provides detailed analysis of jamming and spoofing trends, their operational impact on aircraft systems, and practical mitigation strategies. It also outlines updated pilot procedures and training recommendations aimed at improving situational awareness and response.

The guidance highlights several global regions where spoofing activity has been recorded, including the

Eastern Mediterranean, Black Sea region, Russia and the Baltics, the India–Pakistan border, Iraq and Iran, North and South Korea, and areas surrounding Beijing, China.

While these regions remain high-risk, the FAA also notes that unintentional interference can occur elsewhere, including within the United States. In some cases, faulty commercial equipment has disrupted GNSS signals locally, affecting navigation systems.

One notable example cited is the 2022 GPS interference incident near Denver International Airport, which was linked to such unintended disruptions.

Commenting on the update, Richard Boll, Chair of NBAA’s Airspace and Flight Technologies Subcommittee, stated: “NBAA recognises the problems with GPS interference and the potential for disruption globally, and is taking action to ensure users of the National Airspace System are informed.”

As reliance on satellite-based navigation continues to grow, the updated guidance reflects increasing industry focus on resilience, awareness, and preparedness in managing GNSS-related risks.
