Background

We found no report of GPS jamming or spoofing in Portuguese airspace, and no statement on it from the civil aviation authority, ANAC. The communications regulator, ANACOM, enforces the rules on radio equipment; in 2022 it ran joint inspections with the Maritime Police along the coast between Caminha and Peniche (IARU Region 1, 2022). For the reporting on interference in Portugal, and who it is attributed to, see Western Europe.

Interferências em GPS aumentam na Europa (“GPS interference is rising in Europe”, in Portuguese), from Euronews em Português. Watch on YouTube.

Only hexagons whose centre lies inside the borders of Portugal are counted, so hexagons in neighbouring countries and out at sea are left out. The map is framed on 32.5° N to 42.2° N and 17.4° W to 6.1° W.

Portugal is counted under Western Europe.

Portugal: 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.
