Background

Taiwan's National Communications Commission said in April 2023 that interference over northern Taiwan that month came from a government agency calibrating a radio transmitter (Taipei Times, April 2023). The Institute for the Study of War reported in October 2025 that Chinese fishing boats in the Strait had broadcast false identities, which concerns ships' identity signals and not GPS accuracy (Taipei Times, October 2025). For the reporting on interference in the Taiwan Strait, and who it is attributed to, see the East Asian Seas.

The Taiwan Strait: an aircraft is counted in each layer it crosses, so the rows do not add up.

The Taiwan Strait is a sub-area of the East Asian Seas, not a country. Its figures count the hexagons whose centre lies in its box, 21.5° N to 26.5° N and 116.5° E to 122.5° E.

The Taiwan Strait is counted under the East Asian Seas; its centre also lies within South and Southeast Asia.

Over time

Fewer receivers fed the map in its early years, so compare old and recent days with care: how far back the map goes.

The bold line is a rolling average; the pale line is each day. Days are UTC. The share is red and yellow hexagons as a fraction of all hexagons with enough aircraft that day. Download the series (JSON). How to read it.

Questions

Is GPS being jammed in the Taiwan Strait right now?

On 13 November 2026, 22.9% of the areas we monitor over the Taiwan Strait were affected, 0.0% badly. That is above its 30-day average of 19.6%.

Is it getting worse in the Taiwan Strait?

Yes. On an average day in the last 30, 19.9% of its areas were affected, up from 16.1% in the 30 days before.

Is it safe to fly to the Taiwan Strait?

Airliners carry navigation that doesn't rely on GPS, and NOTAMs warn crews of known interference. The map shows where GPS was degraded, not how safe a flight is: see its limitations.

The Taiwan Strait: low reported accuracy points to interference but does not prove it, and the map cannot locate a transmitter or say who is responsible. How the map is made.

Neutrality. We measure and describe data, it is not our job to take sides. The map records where aircraft lost position accuracy, which can come from jamming, spoofing, military testing, equipment faults or space weather. Our data alone can't say who is responsible, so we don't. When we mention a likely source, it's because a government, regulator or reputable outlet has said so publicly. That is their assessment, not ours, and we link to it. Region names and borders follow common international usage and imply no position on any dispute.
