Background

In January 2025 Brazil's telecom regulator, Anatel, and the Minas Gerais military police shut down an illegal jammer in Belo Horizonte after the air navigation provider Nav Brasil reported that 21 aircraft had lost GPS over Pampulha airport in five days. Anatel said jammers are illegal and put public safety and aviation at risk (Convergência Digital, January 2025). In September 2025 police from Rio de Janeiro and São Paulo, with technical support from Anatel, closed a clandestine workshop in Sorocaba that made anti-drone systems, jammers and GPS blockers (Agência Gov, September 2025). Jammers are also used against vehicle trackers: in February 2025 federal highway police seized one from a stolen car in Pernambuco, and the report said such devices are often used in cargo theft (Diario de Pernambuco, February 2025).

The ionosphere over Brazil is also highly active. A 2021 peer-reviewed review describes how plasma bubbles that form after dusk near the magnetic equator cause scintillation that can make receivers lose lock; in one 2011 case at Rio de Janeiro's international airport it pushed satellite landing-system errors past their alert limit (Journal of Aerospace Technology and Management, 2021). For the reporting on interference in Brazil, and who it is attributed to, see: Americas.

Only hexagons whose centre lies inside Brazil's borders are counted, so hexagons in neighbouring countries and out at sea are left out. The map is framed on -33.8 to 5.3 and -74 to -34.8.

Most affected areas

Place	Share affected	Aircraft affected
São Paulo	31.1%	137 of 441
São Paulo	27.4%	125 of 456
Central South America	15.8%	3 of 19
São Paulo	14.3%	84 of 588
Eastern Brazil	14.3%	3 of 21

Brazil: with few aircraft, one report can give a hexagon a high share; see the limitations.

By altitude

Brazil: Mostly low altitude: points to local, low-power jammers. How this is read.

Aircraft observations by barometric altitude, latest update
Altitude	Aircraft	Share affected
Below 5,000 ft	2,233	13.7%
5,000 to 15,000 ft	4,220	7.1%
15,000 to 30,000 ft	7,784	2.0%
Above 30,000 ft	19,381	1.0%

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

Brazil. 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.
