Russia's jamming of the Global Positioning System (GPS) signal in early June spread to the territory of Estonia and Latvia, but since then the jamming has stopped.
This is reported by the ERR portal.
Interferences and anomalies in the operation of GPS occur occasionally, but as a rule, they last for a short time and are not deliberately created. Since the beginning of Russia's large-scale war in Ukraine, no significant increase in obstacles has been recorded in Estonia.
According to the head of the Department of Consumer Rights Protection and Technical Supervision (TTJA), Erko Kulu, the department's monitoring system registered an increase in GPS interference between June 1 and June 5.
According to the Estonian Defense Forces, jamming the GPS signal is one of the measures that Russia can take to ensure the protection of important objects on its territory. In such cases, situations may arise when artificial interference affects the use of GPS in countries neighboring Russia.
"The likely source of the interference is in the Leningrad region of the Russian Federation, and it could have affected the airspace of Estonia to a small extent. The Latvian regulator of communication networks also recorded an increase in interference," Kulu said.
"Until now, only isolated reports have been received from passing aircraft. The loss of the GPS signal does not affect or threaten the navigational capabilities of commercial and passenger aircraft. Nor does it affect the operation of ground-based GPS devices, GALILEO and other GNSS positioning systems," – he added.
As of the morning of June 5, no disruptions were observed in Estonia, but the TTJA will continue to monitor the situation.
Other states cannot prevent the creation of artificial interference, and it can only be stopped by turning off the equipment causing the interference.
It will be recalled that Estonian Prime Minister Kaia Kallas emphasized that Estonia's entry into the North Atlantic Alliance was a free choice of the country, and Russia's assertion that NATO expansion threatens its security is a myth.
