With a so-called gps jammer, you can protect yourself against a position determination or secret eavesdropping. This misery effort can be of great importance under certain circumstances. Because the danger of being located by your own cell phone or being tapped during important calls is omnipresent and can have dire consequences.

A GPS jammer or GPS signal jammer describes a device with which the signals of the Global Positioning System (GPS) operated by the US Department of Defense are disrupted or completely blocked. Such a transmitter makes it difficult to receive radio signals properly (for example radio waves, television, mobile communications or the GPS signal). For this purpose, electromagnetic waves are emitted which completely or partially superimpose the signals and waves of the disturbed transmitter and thus render them unusable. A jammer can work on the same or neighboring frequencies, whereby the field strength of the jammer and the type of disturbed waves are important.

Interfering with GPS signals requires only a very small amount of interference energy to temporarily or completely block the GPS signal. Because the GPS satellites circling more than 20,000 kilometers above the earth's surface have a relatively low transmission power. Even a small signal jammer can disrupt the signal within a radius of approx. 10 meters. This means that GPS tracking of vehicles with a GPS tracker is no longer possible. A modification of GPS jamming is so-called GPS spoofing. In this much more complicated process, a jammer sends false GPS signals, so simulates the satellite signal in order to e.g. B. to guide enemy vehicles, ships or aircraft on the wrong course.

GPS technology in the vehicle can be disturbed or completely blocked by so-called jammers. Electromagnetic waves superimpose the signals from the transmitter for a short or long term, making them unusable. To do this, the jammer simply has to be near the GPS device. The use of whining is generally prohibited in Germany.
However, such a disruption must be distinguished from the much more complex GPS spoofing, which not only disrupts the transmission, but also transmits completely manipulated data.

In addition, the GPS tracking devices from PLT offer the possibility of continuing to locate vehicles despite GPS jamming. Some of the trackers (e.g. the GPS transmitter "PLT Compact Profi") support so-called cell location (also called GSM location or cell phone location) as an alternative. Locating by means of triangulation within a cell phone cell is not as precise as precise location determination using satellite positioning. But the cell-based GSM positioning system delivers surprisingly accurate results, especially in urban areas, where the location of stolen vehicles can be displayed to within a few hundred meters.

For a long time, FM broadcasting was a monopoly market in Germany. First operated by Deutsche Post and later by Deutsche Telekom and its subsidiary Media Broadcast, which has since been sold to Freenet. The broadcasting operations were paid for by the private and public broadcasters in Germany, which was a lucrative business for the operators.

It has been clear for some time that the redesign is not going according to plan. In the middle of March a hastily arranged round table tried to find a way out. There, antenna investors, location owners, network operators, representatives of private radio, ARD and Deutschlandradio, representatives of the federal states, the Federal Network Agency and the Federal Cartel Office discussed and negotiated. A total of 40 of the most important players in the German radio market came together to prevent the signal blocker.

Digital broadcasting in the form of DAB (Digital Audio Broadcasting) was seen as the successor to analogue VHF broadcasting. It was planned to end analogue broadcasting of broadcasting programs in the EU in 2012, once digital broadcasting had spread. This goal was clearly missed, see analog shutdown. In Germany and Austria, the conventional DAB standard could not establish itself, in Austria it was even discontinued. In the meantime, the incompatible successor DAB + was introduced, first in Germany, and later also in Austria. Although the introduction of DAB was more successful in Switzerland, it has now been replaced by DAB + there too. In the rest of Europe the situation is confusing, in some places operations have been stopped again, in other countries it seems to be partially successful.

GPS tracking technologies are on the rise as new innovations continue to be developed. With the prevalence of smartphones and IoT devices, every location, online search, website visited and purchase made is being tracked. While many people are willing to share their location for good purposes, there is another set of people who want to hide their location.

A GPS jammer is a device used to conceal one's whereabouts by sending radio signals with the same frequency as the GPS device. Once this occurs, the GPS device is unable to determine its position due to interference.

The GPS jamming unit itself is typically a small, self-contained, transmitter that generates a 1575.42 Mhz interference signal over a 5 to 10 meter radius.

A jammer makes it difficult or impossible to receive a radio signal (e.g. from radio, television, mobile communications or GPS) properly. The jamming transmitter, just like the transmitter to be disrupted, sends out electromagnetic waves and completely or partially superimposes the original waves. It can work on the same or a neighboring frequency of the disturbed receiver. The field strength, the modulation of the jammer and the type of the disturbed message are important.

The uav has developed rapidly in recent years and has become a popular product in the market. The uav is widely used, not only in terms of the aerial photography and entertainment we have learned, but with the development of the uav, depending on the size of the uav, which is widely used in military applications, and a medium size uav is used in various aspects, such as agriculture and other industries.

The use of drones in military applications is particularly important. In mechanized battlefield, unmanned aerial vehicles are not only used to collect information, but also serve as important weapons. Therefore, the role of uav jammers in military affairs cannot be ignored.

People have been using drones to smuggle goods for years. Porn, weapons, drugs—god, so many drugs. The tiny whirring machines have proven discreet little contraband-transport contraptions, but one smuggling operation’s astoundingly successful run just got grounded. All of this has benefited from a new approach to fighting drones. This approach solves the current difficulty of managing drones

From July 2015 through May of this year, a drone gang made at least 49 flights into prisons in England and Scotland, smuggling in weed and mobile phones. But authorities just jailed eight people after cameras set up outside a prison in Worcestershire to capture wildlife caught them in the act, according to the BBC.

Drones are controlled by radio frequency in a certain frequency range and GPS blocker for an autopilot. One anti-drones solution is using Drone Jammer to block control signals with high power radio signal. The other solution is hijacking mid-flight drones via GPS or control frequency by sending a spoof signal.

A jammer is an electronic jammer device that emits or retweets an electronic jamming signal, which is used to disrupt or deceive the enemy's electronics, to make it less effective and less effective.It emits electromagnetic waves to disrupt and disrupt electronic devices that normally work on enemy communications and radar equipment.

The drone signal jammer works by interfering drone’s radio frequency, disrupt the communication system between the drones and pilots, making it think it is out of range. The Anti-Drone Gun does not destroy or control the drones; it just forces the drone landing or returns to its starting point. The Drone killer helps to stop unauthorized flying robots from accessing sensitive and vulnerable areas.

Different jammers are available basing on their performances and on the specification of the signal to be disturbed:

Jammer for bugs and mobile phones: these cell phone signal jammers shut down the coverage of mobile phones and smartphones signal, 3G and 4G included, and of all the environmental bugs working on GSM network;

Jammer for GPS devices: used to prevent localizing or tracking devices from connecting to GPS sat signal;

Jammer for cameras: these signal jammers ensure privacy and safety because they can block the operation of a wireless camera;

Radio and Wifi Jammer: used in high risk situations, e.g. by bomb techs working on suspicious packages, these jammers prevent bombs from being activated by remote controllers. Moreover they can prevent all devices connected to Wi-Fi (WIFI blocker) networks from operating.

Jammer for microphones and small recorders: unlike previous devices, this jammers do not use radio frequency to disturb the equipment. They give off ultra-sonic signals (that cannot be heard by humans) putting all microphones out of order, preventing any audio surveillance by sound recorders or bugs.

WiFi and Bluetooth both used 2.4GHz frequency band ,it being used for indoor tracking, which means someone can know your location indoors through the hotspot location triangulation,similar to the cell phone tracking.The hackers can gain your confidential informations using the network, which violate your privacy rights. Jammer-buy store provides you with many wireless signal jammers can help you protect data privacy.

GPS is the frequency range used by navigation satellites to track the location of land, water, and aircraft on which GPS tracking devices are installed. The GPS frequency range has five frequency bands, but only three frequency bands are for civilian use-L1, L2 and L5. GPS is the most extensive tracking spectrum (developed and commonly used in the United States), but there are many other satellite navigation systems: Russian GLONASS, European Galileo, Chinese compass and Japanese QZSS. Depending on the different parts of the world you are in, you may use any of them at the same time, or even rarely use them.

The work of GPS is attributed to radio signals from satellites. The main provider is still the NavStar network of the US military, with at least 24 satellites in operation at any given time. The location of these satellites allows you to always see four of them from anywhere on the surface of the earth.

Each satellite continuously broadcasts its location and time (measured by its on-board atomic clock). The GPS receiver compares the time with its own clock, and then calculates how far away each satellite must be. Once at least four satellites are locked and the error is resolved, it will find their precise location (see graphic). Nowadays, many receivers also use GPS to cheaply and easily access the accurate time given by the satellite clock.

GPS jammer were originally created for government use to hide the location of combat vehicles during high-risk missions. Essentially, a GPS jammer is a small device used to hide your whereabouts from GPS tracking devices that monitor your location and movement. The frequency of the radio signal emitted by the GPS jammer is the same as the radio frequency of the GPS device. Due to the interference, the GPS tracker cannot determine the location of your vehicle.

Modern life essentially requires us to give up data and privacy in daily activities from social media usage to airport travel (ie, biometric-based services such as Clear and TSA Precheck). These practices apply to our vehicles and in some cases also include our private conversations. Due to the constant risks of hackers and data leakage, many people are looking for ways to not only hand over less data, but also to protect themselves from harmful exposures.

Some of the most tempting and easily accessible methods of off-grid include GPS jammers and audio or voice protection systems, sometimes called voice jammers. When considering these different counter surveillance devices, it is important to recognize their differences, especially in terms of legality. GPS jammers are illegal devices, and audio jammers are legal and ethical, and they are named incorrectly because their functions are completely different from highly illegal devices.

A typical GPS jammer is useless. It is an independent device that can be plugged into a cigarette lighter or similar auxiliary power source. It will send interference signals (1575.42 Mhz) at a distance of up to 10 meters, and it is usually placed near GPS devices. After the GPS jammer is powered on, its running time is less than 20 seconds. These devices can meet a variety of needs-Wi-Fi and Bluetooth® connectivity, physical shields, remote controls, and options for use with spy cameras and drones.

NATO News and Information Agency announced on April 6 that a new tool developed by NATO will help NATO prepare a GPS jammer so that the combatant command can see how the device will affect its GPS receiver.

"NATO's adversaries have the ability to reduce or reject the capabilities of GPS," NATO's navigation and identification officer Jean-Philip Soré said in a statement. NATO must take appropriate measures to ensure that allied forces can fight in an environment where troops are degraded or rejected. "

Radar electromagnetic and communication coverage tools or React can estimate how much area a particular GPS jammer will affect. By entering the technical information and location data of known jammers, users can see on the map which areas will be affected by the device and make corresponding preparations.

The software can also be used for other global navigation satellite systems used by NATO, such as the European Union's Galileo constellation.

The agency said that React is currently only used for testing and experiments. This feedback was submitted to the operator during the Trident Jupiter 2019 exercise. Developers are now working to ensure that the software is interoperable with NATO's classified network and can be used to manipulate commands.

React is sponsored by the NATO Navigation and Identification Work Program, and is free for NATO member states.

Tools such as React highlight the alliance’s reliance on global navigation satellite systems for precise positioning, navigation, and timing data, as well as China, Russia, and Iran’s investment in R&D and field jamming equipment. For NATO, this is not just a hypothetical question: In 2018, Norwegian officials publicly declared that Russia interfered with GPS signals during the NATO Trident Jupiter exercise.

Enrico Cassini, NCI’s communications and navigation engineer, said: “NATO must maintain its advantages in the electromagnetic environment, including but not limited to positioning, navigation, and timing services. In recent years, the electromagnetic environment has become more competitive. fierce."

At the same time, the US military has been working hard to overcome the threat of GPS signal jammer. For example, the US space forces are trying to achieve safer military signals through GPS III. Just last year, the US military deployed anti-jamming antennas to the German Second Cavalry Regiment.
