Disruptions in global satellite navigation systems (GNSS) over Latvian airspace were recorded 399 times during the first four months of this year, marking a 56.5% increase compared to the same period last year, according to representatives of “Latvijas gaisa satiksme” (LGS).
In April alone, 109 GNSS disruptions were recorded, up 60.3% from April 2023, when 68 such incidents were reported.
In 2024, a total of 820 GNSS disruptions were recorded. In 2023, there were 342 cases and in 2022, only 26 incidents were reported.
LGS previously stated that these disruptions began in connection with Russia’s invasion of Ukraine and are likely related to the conflict.
However, LGS does not break down the data by individual airlines.
The Civil Aviation Agency (CAA) explained to news agency LETA that it reviews and analyses all reports of GPS signal interference in Latvian airspace. Although these disruptions affect normal civil aviation processes, they do not compromise the safety of aircraft in flight, whether in transit or arriving/departing from Latvia.
CAA emphasizes that flight safety relies on multiple navigation systems, so GPS signal loss does not endanger flight operations. All incidents involving GPS interference are centrally collected and analysed by the European Union Aviation Safety Agency (EASA).
LGS is a 100% state-owned enterprise, responsible for providing air navigation services in Latvian airspace.
Meanwhile, the CAA oversees flight safety and security, monitors compliance with environmental standards for emissions from aircraft, and implements national aviation policy.
