GPS Jamming in the Baltic Sea Region

　　The Baltic Sea region includes Estonia, Latvia and Lithuania, three countries close to the Russian border, and GPS jamming has occurred frequently in recent years. cell phone jammerOn a weekend in April, two Finnair flights from Helsinki to the Estonian city of Tartu were forced to turn around and return to Finland due to GPS jamming. GPS jammer These incidents have attracted great attention from the foreign ministers of the three Baltic countries and have sparked widespread international discussion. signal jammer

　　Lithuanian Foreign Minister Landsbergis figuratively likened the jamming to "turning off your headlights when driving at night", emphasizing its dangers. Estonian Foreign Minister Zahkna believes that this interference is part of Russia's hostile activities and said that countermeasures will be discussed with allies. This hybrid attack not only poses a threat to civilian flights in the region, but may also affect other GPS users, such as ships and navigation equipment at sea.

Causes and impacts of GPS interference

　　Experts point out that it is easy to interfere with GPS using relatively cheap equipment. Although no country has publicly admitted that it is behind the interference signals, officials in the Baltic region generally believe that Russia is the main suspect. These interference signals may come from Russia itself or its Kaliningrad enclave between Poland and Lithuania. One theory is that Russia is trying to protect Kaliningrad from potential attacks by Ukrainian drones by interfering with signals.

　　The impact of GPS interference on aviation safety cannot be underestimated. Although most airports have backup systems, crews have received relatively little training on these systems, resulting in insufficient operational capabilities in emergency situations. Sinkkonen, head of flight operations at Finnair, said that although the immediate impact of interference on safety is limited, its long-term impact cannot be ignored. If this interference continues, the efficiency and safety of the aviation industry will be greatly reduced.

　　Countermeasures and future prospects

　　Faced with the increasingly serious GPS interference problem, the governments of the three Baltic countries are actively taking measures. Mikkelsen, chairman of the Foreign Affairs Committee of the Estonian Parliament, called on allies not to remain indifferent to Russia's interference and urged the international community to take action. In addition, Latvian Foreign Minister Blaze said that relevant agencies are in contact with colleagues in other countries to jointly explore solutions.

　　The international community is also paying attention to this issue and has proposed some countermeasures. First, increase the training and use of backup navigation systems to improve the crew's ability to respond in emergencies. Second, strengthen international cooperation, establish an information sharing mechanism, and promptly report and respond to interference incidents. Finally, promote technological innovation, develop more advanced anti-interference equipment, and reduce the impact of GPS interference on aviation safety.
