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.

The car GPS series signal blocker is the third-generation green gps blocker, which only blocks the signal received by the GPS terminal on site, without any negative impact and interference on the communication and transmission of other surrounding electronic devices. It can cover all GPS signals such as positioning terminals within a range of 2-50 meters (depending on the strength of satellite signals), so that all GPS positioning terminals in the shielded area are fully connected to the outside world.
What is a GPS signal jammer?
Features:
Shield the GPS band.
The effective shielding distance is 5-15 meters (debugged according to customer requirements before leaving the factory).
Easy to carry, small size and light weight.
Low power consumption, no harm to human body, environmental protection.
Effectively interfere with GPS satellite signals to protect the privacy of your location and the confidentiality of information.
Small size, high performance, light weight, large coverage and easy to carry.
Effectively prevent car/mobile phone GPS satellite positioning system positioning.
A notice:
When using a car GPS jammer, you should pay attention to the following points:
1. Is the shielded antenna in good condition?
2. Whether the antenna is plugged in properly when using it.
3. Whether the interface between the antenna and the instrument is tight.
4. Whether the inserted meter is in good contact with the car cigarette lighter socket.
Mainly due to the release of radio interference waves, the GPS locator can be disabled within the specified electromagnetic band range to form the same electromagnetic environment as the device and achieve the purpose of shielding the signal.
GPS devices require a calling card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through the map for user query. The jammer uses the connection between the wireless electromagnetic wave jamming card and the communication base station to achieve GPS positioning, and the user cannot inquire for this purpose.
But first of all, you need to distinguish what kind of signal tracking method your car's GPS uses. Second, go to the electronics market to buy a GPS signal cellphone jammer
There are only two ways for signal tracking: (1) Cell phone signal. (2) Direct satellite tracking signal.
Generally speaking, most GPS positioning signals use mobile phone signals, and the signal is blocked, causing all communication devices within the range to lose their signals. But such a device also has drawbacks for the users who use it: the signal jammer can only be turned on temporarily, not permanently, and the GPS signal can be reused as long as the jammer is turned off.

The problem on the battlefield remains the firepower advantage of the Russian military. In an unequal battle of artillery fire, Ukraine is pinning its hopes on a smarter and more precise war. Aerial reconnaissance was the deciding factor - Ukraine has long been air-launching armed drones. Currently, hundreds of soldiers in the country are being trained in various modes.
Drones play a central role in this war. Ukraine relies on civilian and military drones. In particular, the army used armed TB2 drones from the Turkish manufacturer Baykar "to reconnaissance and strikes against Russian troops and equipment very successfully." The air support also played a decisive role in the symbolic downing of the Russian warship "Moscow" in April. The GPS jammers-equipped drone is said to distract the ship's defenses, so an anti-ship missile attack could come from the other side.
The drone is about 20 feet long and can be fully armed. Ukraine is said to have received more than 50 such models since the war began. More than 10 million euros were recently raised by private donations from the people of Lithuania and Poland to fund two other drones in Ukraine.
Russia’s electronic warfare system still interferes with the U.S. GPS, and after the GPS was interfered by Russia, the UAVs supported by the U.S. and other Western countries to Ukraine will not be able to operate normally, although Russia has been advertised I already have powerful electronic warfare capabilities, but in fact Russia's electronic warfare capabilities are quite limited. At present, Russia's electronic warfare mainly relies on increasing power for drone radio frequency jamming.
From the current point of view, Russia has mastered the ability to interfere with the GPS system. If a conflict between Russia and NATO breaks out, Russia can also show off its electronic warfare capabilities with great fanfare, and the interference to NATO's GPS will also affect NATO. than today's Ukraine.
