Background

The US Maritime Administration warned ships of GPS interference in the Strait in 2019 (Maritime Executive, August 2019). In June 2026 the multinational Joint Maritime Information Center called interference across the approaches to the Strait consistent, without naming a source (JMIC, June 2026). Oman's Maritime Security Centre has told seafarers not to rely on GPS alone (Times of Oman). For the reporting on interference in the Strait of Hormuz, and who it is attributed to, see the Middle East.

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

The Strait of Hormuz is a sub-area of the Middle East, not a country. Its figures count the hexagons whose centre lies in its box, 24.5° N to 27.5° N and 54.5° E to 58° E.

The Strait of Hormuz is counted under the Middle East.

Is it safe to fly to the Strait of Hormuz?

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 Strait of Hormuz: 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.
