GPS Interference by Region
Persistent GPS jamming and spoofing patterns are concentrated in five well-documented regions. Click any region to jump the map there.
Eastern Mediterranean & Persian Gulf GPS spoofing
Cyprus (LCCC), Lebanon (OLBA), Israel (LLLL), Egypt (HECC), and the OEJD/OEDF Saudi sectors have shown persistent GPS spoofing since late 2023. Aircraft regularly report degraded GPS integrity through these airspaces; some operators carry workarounds in their Standard Operating Procedures. Iran (OIIX) and Iraq (ORBB) jamming is conflict-driven and intermittent.
Baltic GPS jamming corridor
Estonia, Latvia, Lithuania, Finland, Poland, and Sweden experience persistent GPS jamming attributed to transmitters in Kaliningrad and adjacent areas, ongoing since 2022. Several airlines have rerouted or suspended Baltic schedules; ILS-reliance has increased on affected approaches. EASA published Conflict Zone Information Bulletins covering parts of this corridor.
India & Pakistan GPS interference
South Asia surfaced as a notable GPS interference zone after Phase C global expansion. Indian FIRs (VAAH Ahmedabad, VOMM Chennai, VOBG/VOBL Bangalore) have shown elevated jamming ratios in early observations. Pakistani airspace (OPKR Karachi, OPLR Lahore) sees intermittent interference correlated with regional tensions.
North Africa & Sahel airspace risk
Libya (HLLL), Sudan (HSSS), Somalia (HCSM), and the Sahel corridor (DAAA Algeria, GMAC Morocco, GVSC Cape Verde) have shown a mix of jamming and spoofing patterns linked to regional conflicts and military operations. Coverage is sparser than MENA due to fewer ADS-B receivers.
Romanian (LRBB), Moldovan (LUKK), Bulgarian (LBSR), and Ukrainian sectors (UKBV, UKLV) adjacent to the conflict zone show intermittent GPS interference spikes correlated with conflict dynamics. Smaller hotspots: Caucasus corridor (UDDD Armenia, UGGG Georgia), Kaliningrad-adjacent Polish airspace, and parts of Central Asia. Coverage of these regions improves as OpenSky receivers come online.
Methodology
Every 20 minutes, FlySafe queries OpenSky Network for ADS-B state vectors globally. For each aircraft we evaluate NACp (Navigation Accuracy Category for Position) and position staleness; aircraft scoring NACp < 7 or with stale positions are flagged as GPS-degraded. The jamming ratio is the share of degraded aircraft per FIR.
Raw 20-minute observations are aggregated to daily maxima (worst-of-day, more informative than mean for jamming). The 7-day average of daily maxima is the headline metric on the map. 30-day daily-max sparklines show recent trend per FIR.
Phase C global bounding box (full globe). Coverage data since 2026-03-25. Total measurements ingested: 77,685 across 311 FIRs. FIRs with no measurements yet (recent expansion regions) display gray.
- • Daily snapshot — not real-time. Use the API for sub-hour resolution.
- • Indirect signal — NACp degradation correlates with jamming but doesn't prove it. Receiver issues, GNSS outages, and localised interference all show up.
- • Sparse FIRs with insufficient measurements display as "no data" rather than guess.
- • OpenSky receiver coverage — sparser over oceans and polar regions; some Pacific / Atlantic FIRs may underreport.

Frequently Asked Questions
What is GPS jamming and how does it affect aviation? +
GPS jamming is the deliberate or incidental transmission of radio signals on GPS frequencies, blocking or weakening the satellite signal that aircraft rely on for navigation. Most modern airliners can fall back to inertial navigation systems and ground-based navaids, so jamming rarely causes immediate danger — but it forces flight crews to use backup procedures, can affect approaches that depend on GPS (LPV/LNAV/VNAV), and is a strong indicator of nearby military activity or conflict.
How is this map different from GPSJam.org or other public GPS interference trackers? +
Both this map and GPSJam.org derive their signal from the same underlying ADS-B observation — aircraft self-reporting degraded position integrity (NACp). The differences: FlySafe aggregates per Flight Information Region (a unit aviation professionals work in, not arbitrary grid cells), publishes a 30-day daily-max sparkline per FIR, and pairs the public daily snapshot with a paid 15-minute API for operational use. We attribute OpenSky Network as the data source; gpsjam.org also publishes great open data and is complementary, not competitive.
Is GPS jamming the same as GPS spoofing? +
No. Jamming overwhelms GPS signals so receivers report no fix. Spoofing transmits fake GPS signals, so receivers report a wrong fix — believing they are somewhere they are not. Both show up as NACp degradation on ADS-B, so this map captures both types under one signal. Spoofing is generally more dangerous because it can mislead a flight crew without obvious warning; ICAO and IATA have flagged spoofing as an emerging operational risk, particularly in the Middle East and Eastern Mediterranean since 2023.
Why does my region show as gray (no data)? +
Either OpenSky Network does not have ground-receiver coverage for that region (sparser over oceans and parts of Africa, Pacific, and polar regions), or aircraft traffic in that FIR is too low for our minimum-observation threshold. Coverage improves continuously as the OpenSky community adds receivers; the map will fill in over time.
How often is the map updated? +
Daily, at 06:00 UTC. Underlying raw observations are collected every 20 minutes from OpenSky Network. The public daily snapshot intentionally lags the raw data — for sub-hour resolution suitable for operational use, see the programmatic API access section below.
Can I use this data in a published article or report? +
Yes — under the CC-BY 4.0 license. Use the citation block above; please include a link back to flysafe.zone/tools/gps-interference-regional-map/. For high-resolution visuals, custom timeframes, or quote-ready statements for press, contact [email protected].
