# GPS Jamming and Spoofing
> GPS jamming blinds navigation receivers while spoofing fakes their position; deployed by Russia, Iran, North Korea, and India, the attacks now threaten global aviation, shipping, and weapons guidance.

## What it is

GPS jamming and spoofing are two distinct attacks on the same vulnerability: civil satellite-navigation signals arrive at Earth from orbit at roughly -130 dBm, far too weak to resist a nearby radio emitter. Jamming floods a receiver's frequency band with noise, rendering the signal unreadable; it is crude but cheap and can affect receivers across hundreds of kilometres with off-the-shelf hardware. Spoofing broadcasts counterfeit GNSS signals that mimic the real ones, convincing a receiver it is in a different location or time, a far more dangerous capability that can silently redirect aircraft, ships, or missiles. Both attacks exploit the same structural weakness: civil GPS and all four global constellations (GPS, US; Galileo, EU; GLONASS, Russia; BeiDou, China) broadcast unencrypted, unauthenticated signals that receivers must accept on trust. The primary actors are state militaries, which use jamming and spoofing to blind adversary drones, ships, and precision weapons in conflict zones, and commercial criminals, which deploy low-cost jammers to defeat vehicle-tracking systems in transit fraud.

## History

The US GPS constellation reached full operational capability in 1995 with 24 satellites. Military planners treated jamming as a near-peer threat from the start, but civil-signal interference remained rare and localised for two decades. North Korea began large-scale deliberate jamming of South Korean receivers in 2010 and again in 2012 and 2016, disrupting thousands of aircraft and ships. Russia's 2014 annexation of Crimea marked the start of a persistent Baltic campaign, with interference traced to Kaliningrad and the Kola Peninsula. From 2019, incident counts rose sharply across multiple regions. The ITU Radio Regulations Board issued a formal warning in March 2021, repeated the call at the World Radiocommunication Conference in 2023, and published a joint statement with ICAO and IMO in March 2025 calling the scale a crisis for global transport safety.

## Current state

As of early July 2026, GNSS interference is, in the words of the Secure World Foundation's 2026 annual report, "a constant of modern conflict." In the Baltic region, roughly 40% of European air traffic has experienced interference; Poland logged 2,732 aircraft interference cases in a single month (January 2025) and Sweden reports incidents occurring "almost daily." Lithuania counts Russia's spoofing-antenna network as having grown from 3 to 36 since early 2025, a twelve-fold expansion, with signals traced to Kaliningrad and the Kola Peninsula. Estonia documented over EUR 500,000 in economic damages within three months of mid-2025. In June 2025, Iran jammed GPS across multiple metropolitan areas during its twelve-day conflict with Israel, disrupting an estimated 970 ships per day in the Strait of Hormuz and cutting traffic there by 20%. India deployed electronic warfare against Pakistani navigation signals in May 2025; over 10% of Delhi-region flights reported spoofing incidents in the immediate aftermath. The ITU Radio Regulations Board formally demanded in November 2025 that Russia cease harmful interference, backed by ICAO and IMO condemnations of both Russia and North Korea in October 2025. As of mid-2026, no binding enforcement mechanism has been applied.

## Relationships

The jamming epidemic is the single biggest structural driver of the [Galileo Gen-2 and BeiDou refit](/zh/n/galileo-beidou-pnt-2026) programmes, pushing GPS, the EU, and LEO-PNT startups toward multi-constellation, anti-spoofing-capable receivers as a resilience layer. The detailed European theatre escalation, including the EU's move toward naming sanctions and the [aviation incident record](/zh/n/gps-jamming-aviation-2026), is tracked in the aviation node. The four sectors most acutely exposed are aviation, maritime shipping, financial-market timing (which uses GPS timestamps), and weapons guidance. Autonomous vehicles and precision agriculture are the two civilian growth industries whose commercial trajectories depend most directly on solving the interference problem.

## What to watch

- Whether EU sanctions name and deter specific Russian operators, or remain symbolic.
- Any aviation incident or near-miss directly attributed to GPS spoofing, which would force faster regulatory action.
- ITU enforcement proceedings: the Radio Regulations Board can recommend but cannot compel member states.
- Uptake rates for multi-constellation receivers and Galileo Gen-2 anti-spoofing hardware as the technical mitigation.
- Whether North Korea and Iran expand or refine their spoofing capabilities based on operational feedback from the 2025 conflicts.
