Finland has a long and complex history with neighboring Russia. Since the president's visit to Washington, much of Finland's air traffic has been crippled by GPS signal outages.
Planes have been reporting GPS jammer gps on Finland's eastern border since last Tuesday
interference. Unrest intensified around the Russian enclave of Kaliningrad on Wednesday and on the Finnish-Norwegian border on Thursday.
However, the unrest has affected not only the immediate border areas, but much of the country. Flights between Helsinki and Savonlinna in the east of the country are currently considered infeasible and have been cancelled at least until the beginning of this week. A GPS jamming alert was also issued for flights between Mikkeli and Kuopio, the largest city in eastern Finland. In addition, most of Finnair's European flights pass through Kaliningrad.
Earlier, Finnish President Sauli Niinistö visited the United States. The exact cause of this phenomenon remains unclear. Even if Russia supports it, experts can't say for sure. However, suppose only one country could be responsible for a disruption of this magnitude. "If [interference] was caused by external influences, it would definitely be said publicly," Prime Minister Sanna Marin said, according to the British newspaper The Guardian.
The last time Finland experienced such a blackout was in autumn 2018, during a NATO exercise. At the time, unrest also affected northern Norway and Finnish Lapland. At that time, the Russian army on the Kola Peninsula can be identified as the fuse.
GPS signals can be corrupted in two ways: jamming and spoofing. signal jammer device produce invalid or incorrect location data. Russia has previously raised concerns about GPS spoofing. However, flying is said to be safe even in the event of a GPS malfunction, and there are procedures in place for such situations, the head of the Finnish transport agency said.
The Global Positioning System (GPS) was originally developed by the U.S. Department of Defense and continues to be operated and controlled by the U.S. government. Due to the low signal strength, it is easy to suppress with additional signal, at least in smaller areas. However, the US government can allegedly distort or shut down the signal.

GPS Jammers and Jammers - Still Using Smart Hardware Location A GPS jammers is a device used to jam or completely block Global Positioning System (GPS) signals operated by the U.S. Department of Defense. Such transmitters have difficulty receiving radio signals correctly. For this purpose, electromagnetic waves are emitted that completely or partially superimpose the signals and waves of the disturbed transmitter, rendering them unusable. Jammers can operate on the same or adjacent frequencies, the field strength of the jammer and the type of jamming wave are important.
GPS jamming requires very little jamming energy to temporarily or completely block the GPS signal. Because GPS satellites orbiting more than 20,000 kilometers above the Earth's surface have relatively low transmit power. Even small GPS jammers can jam signals within a radius of about 10 meters. This means that it is no longer possible to GPS track the vehicle with a GPS tracker.
Mobile Smart Positioning Devices Offer Special Protection Against GPS Interference Mobile Smart GPS Tracking Transmitters provide the option to continue locating the vehicle in the event of GPS interference. The tracker supports so-called cell positioning (also known as GSM positioning or cell phone positioning) as an alternative.
Such cell phone blocker are used time and time again in criminal cases. The perpetrator tries, for example, B. to overcome the anti-theft system in the case of shoplifting. Car locks are also increasingly being manipulated by jammers to open vehicles and steal items from them. If the entire vehicle is stolen, thieves use GPS jammers to block GPS signals over a wide area. Tracking systems used for vehicle tracking usually show the fleet operator the location of his truck or car at any time, so they cannot be used.
Protecting Against GPS Jammers and Jammers In areas of particular security relevance, the use of sophisticated technology can reduce the effectiveness of GPS jammers. For example, in aviation or the military, special antennas are used that only receive signals from a certain direction. However, this technology is rather impractical for companies in the logistics and transportation, trade, construction or service industries who want to use GPS tracking to monitor cars, trucks or construction machinery in their fleets.
In this regard, there is always a residual risk that GPS positioning will be corrupted by criminal energy to disable anti-theft protection or use the vehicle for unintended purposes. However, it should also be noted that the use of GPS jammers can result in serious criminal penalties. Because buying GPS jammers and using them is not only prohibited, but can also be very dangerous, as radiation can also damage sensitive instruments (such as in ambulance or traffic control systems). may interfere. Statistics from the Criminal Police also prove that locating vehicles or trucks using GPS trackers installed in vehicles is an effective method of locating stolen vehicles, even if they have been taken abroad.
While GPS jammers are banned, fleet operators should protect themselves. Certain gangs specifically target valuable machines and trucks.

What should I pay attention to when using GPS jamming?
Grid, mobile or military radios - many of today's systems are highly dependent on GPS signal jammers. Jammers can have dangerous consequences.
The GPS-assisted system, designed to help pilots land commercial planes in bad weather, malfunctions twice a day, even though the technology shows no error. It took months for airport management to discover the error: it was a truck driver driving a GPS jammer on the highway because he wanted to save on GPS tolls. Using such devices for toll fraud is clearly beyond the scope of legality, but they are still very easy and cheap to buy.
Mail-order sellers sell the devices for just over 30 euros, and drivers simply plug them into the vehicle's 12-volt cigarette lighter socket to operate. Interference from Global Positioning System (GPS) signals is very good because they reach the Earth's surface very weakly. Each satellite transmits 200 watts of power over a distance of approximately 30,000 kilometers.
As long as someone opens their mouth, you can't hear it, like receiving an audio jammer next to the ear. A transmit power as low as a watt or two is enough for the small hum from the GPS to often cause confusion far beyond the expected range.
The sensitivity of GPS can be seen from the fact that it is large in strong solar winds that can obscure entire continents, or that a poorly shielded FM radio tuned to the correct frequency can simultaneously receive GPS signals from Earth.
In addition to the toll fraud described, there are other typical reasons for interfering with nearby GPS receivers. For example, there are many providers of automated vehicle trackers, some of which are used for fleet management but mainly for tracking in the event of a theft. The small battery box can be installed very discreetly and transmits its current location via the mobile network to the supplier's central tracking computer at set intervals.
This equipment has been standard on yachts for many years. It is also common for thieves to disable this device frequently. Police authorities also use small GPS trackers to monitor people, which they secretly attach to vehicles to be tracked. Finally, some control freaks compulsively monitor their life partners electronically. One tends to see the only legitimate reason for GPS jammers here, although the escalation to electronic warfare might break down anyway.
Because as a society, we are so used to the constant availability of GPS that we take it for granted. Alternative navigation features are increasingly degraded.
This can be seen in normal road traffic as a seemingly normal person drives through bushes because "the navigation system says I should". This can also be seen among professionals on the high seas. Anyone who has ever navigated a boat on a GPS chartplotter will immediately wonder how they could have navigated differently, and often just a little later and can't get it right.

Over the last few years, several of us in the GNSS community have done our best to convince our colleagues, policymakers, and the general public that unsavory characters with GNSS jammers or spoofers are a genuine threat to GNSS and an orderly society.
My response? Hackers, because they can. Thieves planning to snatch expensive cargo. A moonlighting employee in the company car. Worse yet, state actors or terrorists targeting our national infrastructure.
I have until now tended to avoid any mention of upstanding citizens or upright motives. But a sober examination of the trends in GNSS innovation has led me to believe that there are perfectly legitimate reasons why otherwise law-abiding citizens could be sorely tempted to use GNSS jammer or spoofer.
Over the last decade, GPS accuracy has only improved. With today’s GPS reference stations, better algorithms, and better receivers, stand-alone civil GPS can now identify not only the street, but which side of it you are on.
Our modern society has an almost blind reliance on GPS. It’s built deeply into our systems and infrastructure. Some call it the invisible utility. In this environment, turning on GPS jammer could be deadly.
I am fascinated by this looming conflict between the need for privacy on the one hand, and the need for a clean radio spectrum on the other. We simply cannot tolerate jammers and spoofers, and yet, given the lack of effective legal means of protecting our privacy from the GPS dot, can we blame people for wanting to use them?
My hope is that we will resolve this conflict with some yet undiscovered technical innovation.
But can you resist the temptation to track down your fellow human beings? Can you resist the temptation to turn on your GPS jammers to protect your privacy?

GPS jamming attacks from North Korea have increased in frequency and duration since they began in August 2010, prompting the South Korean government to implement an enhanced Loran (eLoran) system that will cover the entire country by 2016.
The South Korean government completed the design, development and construction documents for the eLoran system in February, and will procure the system infrastructure through an international competitive tender.
GPS jamming attacks from North Korea have increased in frequency and duration since they began in August 2010, prompting the South Korean government to implement an enhanced Loran (eLoran) system that will cover the entire country by 2016.
The South Korean government completed the design, development and construction documents for the eLoran system in February, and will procure the system infrastructure through an international competitive tender.
Last year, 1,016 aircraft and 254 ships in South Korea experienced GPS outages during 16 days of North Korean interference. The frequency and duration of North Korean GPS jammers jamming has been increasing since four days in 2010.
The Korean eLoran system aims to provide better than 20 meters of positioning and navigation accuracy nationwide.
The South Korean government hopes to work closely with Russia and China in the near future to expand eLoran’s coverage throughout Northeast Asia.
The Korea eLoran system is expected to meet the accuracy, availability, continuity and integrity requirements for ship port entry and approach (HEA) and aircraft non-precision approach (NPA).
The eLoran system will be procured through International Competitive Bidding (ICB). Enhanced Loran improves upon previous Loran systems by using updated equipment, signals and operating procedures. These changes enable eLoran to provide better performance and additional services compared to Loran-C.
The researchers also noted that North Korea appears to be experimenting with their mobile signal jammer, operating at various transmit powers, frequencies, and jamming intervals.
