GNSS Interference: GPS Jamming & Spoofing in Aviation

GNSS interference is the deliberate jamming or spoofing of the satellite navigation signals that aircraft rely on for position, navigation and precise timing. Jamming denies the signal; spoofing replaces it with a convincing fake.

Conflict Zone & Overflight Risk: The Complete Guide

Open airspace is not safe airspace — a core lesson from MH17 and PS752. This guide breaks down how structured conflict-zone overflight risk assessments work in practice, from SAM-system threat mapping and GNSS interference to regulatory prohibitions, insurance pressure, and repeatable decision workflows.

What Is Aviation Security? The Complete Guide

Aviation security covers far more than checkpoint screening — from conflict-zone overflight and GNSS spoofing to insider threats and cargo supply-chain controls. This guide maps the full scope, the international framework, and how airlines assess and manage security risk today.

GNSS Vulnerabilities at Major U.S. Hubs: LAX and JFK GPS Degradation and NOTAM-Driven Navigation Constraints

NOTAMs at LAX and JFK signal GPS interference and aging DME outages that narrow approach options and expose a critical gap: RNAV-equipped aircraft lose their primary navigation source with no DME fallback if GPS is jammed or spoofed.

Middle East and North Africa Overflight Risk: GNSS Jamming, Military Activity, and Airspace Closures in 2026

Sustained GNSS jamming below FL320, SAM activity over Yemen, and near-zero ADS-B traffic across six MENA FIRs signal a materially elevated threat environment in 2026. Operators must treat active NOTAMs as hard avoidance zones and validate inertial navigation redundancy before any regional operation.

Military Aircraft Activity Surge in Ukraine Airspace Despite Ongoing Conflict Risk

ADS-B surveillance has detected multiple military transport and logistics aircraft inside Ukraine's Kyiv FIR, confirming the airspace remains operationally active and contested. Civil overflight is not viable for standard commercial operations without government coordination, dedicated corridor approval, and…

Cairo FIR Military Activity and Suez Region Risk: Implications for North Africa and Red Sea Overflight

Active military operations confirmed inside Egypt's Cairo FIR—including surveillance aircraft and air-defense readiness—raise the operational risk profile for carriers transiting Red Sea, Suez, and Mediterranean corridors.

Baltic GPS Jamming in 2025: A GNSS Integrity Case Study

GPS jamming over the Baltic became routine in 2025. Lithuania logged more than 1,000 interference reports in June alone — 22 times the prior year — and jamming has already forced scheduled flights to divert.

What Is Conflict Zone Airspace Risk? Overflight Risk Explained

Conflict zone airspace risk is the danger civil aircraft face when flying over or near areas of armed conflict — from surface-to-air missiles to GPS jamming. Here is how the risk arises, who warns about it, and how operators decide.
