Disturbances in satellite navigation
According to the Estonian Transport Agency on June 17, Estonia together with Finland warned against navigation interference in the Gulf of Finnish. The warning concerns territorial waters and the exclusive economic zone of both countries. Since the beginning of the year, the level of disturbance in the functioning of global satellite navigation systems (GNSS) in the region of the Gulf of Finnish, and in June it has been intensified, as it was transmitted in the communiqué.
Global GNSS system
GNSS (Global Navigation Satellite Systems), i.e. a satellite navigation system It covers the American GPS, but also the Russian Glonass system, European Galileo or Chinese BDS. Estonia And Finland report disturbances in the International Maritime Organization (IMO), which sends information to 176 Member States. In recent days, the level of interference has been classified as “high”.
Provocated incidents or exercises?
Estonia Together with 12 other countries, EU called the European Commission to react last week. As stated in the application, disruptions in the operation of navigation systems “They are not accidental incidents, but a systematic, intentional action of Russia and Belarus” aircraft or ships. “There is no doubt that Russia in this has a finger in this thing,” said Minister Siemoniak recently. But An alternative explanation is the NATO Baltops 25 exercises. (lasting from 5 to 20 June), during which various types of electronic combat methods can be tested.
Disturbances also over Poland
According to the information provided in June by Finnish border services and maritime transport The number of GPS interference at sea has increased this year three times. From January to May, 84 such cases were recorded at sea, when last year There were only 27 of them. Therefore, it is important that the crews of units that flow through the Gulf of Finnish are familiar with traditional sea navigation using a map and compass, without electronic devices. Similar problems appear over Poland. The plane from Alicante, instead of landing in Bydgoszcz, was redirected to Poznań. Although the situation was mastered, the map shows that disturbances GPS They cover a significant part of the country. Even car navigation is in trouble – in the Tri -City GPS showed that the vehicles are found at sea or in Russia. Several drones fell on the Baltic Seaover which operators lost control. This may suggest disturbing the frequencies that are used when communicating with this type of machine.
