Category: Tags GPS

GPS is a frequency range used by navigation satellites to track the location of land, water and aircraft with GPS tracking equipment installed. The GPS frequency range has five frequency bands, but only three frequency bands are available for civilian use-L1, L2 and L5. GPS is the most extensive tracking spectrum (developed and widely used in the United States). In this category, you will find several GPS jammers (anti-tracking devices) that will help you protect the privacy of your vehicle or any other place.

What are cell phone jammers trying to tell us?

Cell phone jammers prevent phones from working. They are used in cars, public places and exam halls.

Jammers are not new – they have been around for years – and they are illegal in many countries, including the United States, but jammers are becoming increasingly popular.

But are phones really the problem? And are jammers really the solution?

I think cell phone jammers are being used as a patch, the wrong solution, to solve three societal problems that should be solved by much better technology.

Here are the three biggest problems cell phone jammers are trying to solve, and what I think are the better solutions.

The “phones are dangerous” problem

A Florida man named Jason R. Humphreys wanted to save lives by preventing people on his daily commute from using their phones while driving. So Humphreys installed a cell phone jammer on the back of the passenger seat of his SUV. As far as Humphreys knew, the program worked for two years. But the police, whose own communications were occasionally interrupted by his jammer, were less than enthusiastic. So they tracked him down and caught him two years ago. Last week, he was fined $ 48,000 by the Federal Communications Commission for violating US law against jamming devices.

As I said at this point, I think that drivers distracted with smartphones would be distracted by something else without smartphones. In other words, smartphones don’t cause accidents, humans don’t.

The terrible reality is that human drivers kill around 1.24 million people worldwide every year. That is a far higher annual rate than the number of people who die in wars.

Humphreys’ misguided act was the wrong solution to the problem. What we really need is to switch to self-driving cars as soon as possible. The sooner we do it, the more lives will be spared.

Advanced drone jamming technology developed

Security forces around the world are facing a growing threat: radio controlled drones flying or hovering over crowded stadiums, prisons and places with high concentrations of people. The drones can spy on, record and broadcast unauthorized videos. They can also transport explosives, illegal goods, and other products. and even carry out terrorist attacks, murder VIPs, etc.

In response to these threats, a new unmanned aerial vehicle drone jammer was developed. Developed for military use, the DroneBlocker jammer can block small to medium-sized aircraft in a variety of ways.

The system developed by IACIT from Brazil can be used by the military who want to secure bases and airports. The Brazilian Army is currently using the jammer for a variety of confidential applications including protecting VIPs and important events, Henrique Nobre, IACIT general manager for sales and marketing, told janes.com.

The Brazilian Armed Forces reportedly used the system during the 2016 Rio de Janiero Olympics. The system has been successfully demonstrated in different countries in ten different infrastructures (airports, critical structures, etc.).

How does it work? The technology can disrupt a UAV’s Global Positioning System (GPS), forcing the aircraft to land gently. It can also force the UAV to return to its original location. Additionally, it can prevent imaging streams from returning to the operator, thereby thwarting the mission assigned to the UAV.

The innovative technology works with several sensors. The company developed an image processing algorithm that could detect targets such as UAVs based on the video from surveillance cameras installed along a perimeter. The camera subsystem detects the target and sends a message or trigger to the jammer subsystem to activate it.

A radio frequency (RF) sensor detects targets by receiving the RF signals with a database and looking for a signature protocol that matches the signal generated by the aircraft and / or its operator. According to the company’s website, there are two versions, the military 110 and the civil 0200.

The system consists of cameras, RF receivers, acoustic sensors (optional), radar (optional) and jammers, all of which are integrated. It offers 24-hour protection, completely independent operation (operators are not required) and the creation of event records. The configuration is flexible and offers product versions with an output power of 1 W, 10 W, 50 W and 100 W per channel.

The platform includes the installation of antennas on the roof of the structures to be protected or on portable masts for special tactical missions or for protection against major events.

GPS disturbed: Russia is playing with America’s F-35

Russian forces have blocked GPS systems in the Middle East. The electronic warfare campaign could affect US forces gathering in the region ahead of possible strikes against Iran.

“Since last spring, pilots flying through the Middle East, particularly in Syria, have found that their GPS systems have displayed the wrong location or have stopped working,” The Times of Israel reported in late June 2019.

According to a US-based researcher, the signal that has disrupted satellite navigation for aircraft flying through Israeli airspace in recent weeks comes from a Russian air force base in Syria.

This disruption in the reception of the Global Positioning System does not appear to be specifically aimed at Israel, but rather the Jewish state is likely to be collateral damage as Moscow tries to protect its troops from drone attacks and assert its dominance in the field of electronics, Professor Todd Humphreys at the University of Texas, told The Times of Israel.

cheap signal jammers

Israeli sources “are increasingly convinced” that three weeks of GPS glitches for civilian flights is a side effect of Russian interference and spoofing in Syria, Breaking Defense reported. “Moscow is trying to interfere with both Western aircraft – including state-of-the-art secret F-22 and F-35 – and improvised terrorist drones.”

The US Air Force, which will take off in April 2019, has dispatched F-22 and F-35 stealth fighters to Qatar and the United Arab Emirates, respectively, to strengthen the armed forces, while Washington, following the decision of the US President Donald Trump clashes with Tehran unilaterally for the United States to withdraw from the agreement to limit Iran’s nuclear program.

Now the situation is rife with rumors as the Israeli government eschews any official statement and continues to investigate other sources. But if Russia actually accidentally disrupts a friendly nation’s GPS, then why didn’t they stop?

The answer could lie within the confines of Russian electronic warfare, which, while far more effective than the US military [electronic warfare], is still based more on raw power than on precise aiming.

The International Federation of Air Line Pilots’ Associations and the Israeli Airports Authority announced in late June 2019 that many flights lost GPS satellite signal while flying in or out of Ben Gurion International in Israel, Breaking Defense reported. According to the IAA, there is no risk to passengers. The affected aircraft simply switched to backup systems.

“Interestingly, ground-based GPS systems are not affected,” stated Breaking Defense. “That makes the aviation GPS malfunction suspiciously specific – another sign that it is not a simple glitch, but some kind of electronic weapon. And the Russians have invested heavily in powerful spoofing systems, the wrong GPS Send signals that are up to 500 times stronger than the real ones, which leads civilian navigators astray for miles. ”

Russia also disrupted GPS in Europe

“In late October [2018], encrypted GPS signals were first discovered during NATO’s large-scale Trident Juncture exercises in Norway,” Defense News reported.

“Norwegian Intelligence said it was tracking the source of the signal blocker to a Russian military base on the nearby heavily fortified Kola Peninsula. Finnish Military Intelligence said Norway’s analysis reflected its own research and assessments.”

anti-tracking gps blocker

In late 2018, Finland and Norway filed complaints with Russia about the disruptions. “Defense and civil aviation chiefs in Finland and Norway warned that the GPS jammer posed a serious risk to military and commercial aircraft using the affected airspace in the far north,” said Defense News.

“Russia has asked (us) to provide evidence. We gave them the proof, ”Norwegian Defense Minister Frank Bakke-Jensen told Arctic Today. The evidence consisted of measurements that showed that signals had been jammed.

“Russia said, ‘Thank you, we will come back when our experts review,” said Bakke-Jensen. “To have such a response from Russia is a positive thing,” he said.

Bakke-Jensen implied the interference was intentional. “They trained very close to the border and they knew that this would affect areas on the other side,” Bakke-Jensen said of the Russians.

The US Army plans to test jam-resistant GPS systems in Europe to counter Russian electronic warfare.

The 2nd Cavalry Regiment of the Army in Germany is to receive the new interference-resistant GPS by the end of 2019.

South Korea accused North Korea of ​​jamming GPS signals

South Korean authorities said North Korea is using so-called radio jammer to suppress GPS navigation systems in border areas.

According to the authorities, it started about a month ago in several places at once along the border, but stopped last Thursday.

buy signal jamming device

This reportedly led to disruptions in the navigation systems of 110 ships and aircraft, as well as to interruptions in mobile telephony.

A spokesman for the South Korean ministry for the unification of the two countries called these actions by Pyongyang a provocation, Agence France-Presse reports.

South Korean media report that Seoul has accused its northern neighbor of jamming GPS signals for at least the fourth time since 2010.

At the same time, it is reported that, most likely, the equipment for signal suppression was supplied to the DPRK from Russia.

On Friday, the South Korean military reported that the DPRK had once again launched a ballistic missile at sea, despite international sanctions and criticism from world powers.

Last week, North Korea announced an artillery exercise simulating an attack on the official residence of the South Korean president.

Whether the signal shielding device can shield all communication signals

Nowadays, the emergence of shielding device has solved many hidden dangers of disrupting the order in the examination room, so that candidates can take the exam in a fair environment. The principle of this kind of test signal jammer is actually to block the communication signal of the mobile phone by isolating the electronic signal, which can prevent the phenomenon of using the mobile phone to cheat.

smartphone signal blocker

Generally speaking, the effective range is within a radius of 0 to 30 meters. Generally, a low-power test signal jammer is enough to cover an entire classroom, which meets the needs of the test room for shielding signals, and is especially suitable for schools to purchase signals for the test room. shield.

Can the test signal jammer block all communication signals? Speaking of it, many people are unfamiliar with test signal jammers. In fact, it has been widely used in the college entrance examination examination room. In the college entrance examination last year, many examination rooms installed this kind of equipment and received it. Many good responses have been proven to have a good effect on preventing electronic signal cheating. Starting this year, it has been vigorously promoted to allow more examination rooms to install shields.

Something about the frequency of GPS jammers

GPS jammer is the main role is to prevent GPS tracking device. We were told about how it works in the article “what is misery”. If you are concerned about someone chasing you, you may need a GPS jammer to prevent others from using the GPS tracker to track you.

gps signal jammer for car

Before you buy it, there is something you should be aware of about these devices. One of the main issues to check when purchasing a GPS jammer is its frequency of operation. Because GPS tracking devices use a variety of frequency bands, especially the GPS L1 band, but there are other frequencies to use, so you need to know the frequency and choose what you need to set their working frequency. Please note that the frequency of the jammer used must be the same as the frequency used by the GPS tracking device for the jammer to work effectively. There are hundreds of GPS jammers on the market so it should be easy to find a jammer that suits your needs and requirements.

If you don’t know the frequency of these trackers, don’t worry. There are many types of GPS jammers, some of which block a primary GPS L1 frequency, and some may be able to block several at once. Of course, there are many high-end models that can block any tracking frequency (GPS L1 L2 L5, GLONASS, Galileo, Compass, etc.) If you want to be sure you haven’t “followed” these tools are yours Option, and of course these devices can be quite expensive, so you should determine how much money you will be making. Surely the GPS jammer can help you keep GPS tracking.

GPS jammers have different qualities – battery life and the frequency of assistance. The most important is the frequency of device support. Battery life is also an important characteristic, and if you plan to use Jammer for a long time, it should be checked carefully. In general, the battery life of portable jammers cannot be used for a long time on a single charge. If you’ve been wanting to use Jammer for a long time. Desktop jammers are better because they are generally used when loading.

Talk about the 4 advantages of wireless signal jammer

In the last few years, various types of cell phone jammer have emerged in an endless stream. We are dazzled and dizzy. In fact, not all products are suitable for us to apply to ourselves. Some products are public, so they are not suitable. There is a very special jammer used in other fields by us, and it also appears in front of us. Its name is wireless signal jammer. So what are the advantages of this type of product?

When we use a wireless signal jammer, you will find that no matter where we are, as long as we can turn on such a jammer, no one can search for our wireless signal. In other words, home The effect of the product is more obvious than that of common public products. In such an environment, we can always shield all signals easily, but if we use a public shield, then the shielding effect may be unstable The problem, so we need to understand the specific use effect.

Bluetooth jammer blocker

What are the advantages of wireless signal jammers? The following editor from Chengdu Saiyue will explain the 4 advantages of Saiyue wireless signal jammer one by one.

1. Wide application
Wireless signal jammer is mainly used in examination rooms, but not limited to examination rooms. They can also be used in prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, Only used in libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries guarding the scene).

2. Strong pertinence
Wireless signal jammers can be mainly used for domestic college entrance examinations, domestic college entrance examinations, adult college entrance examinations, self-study examinations and various colleges and universities examinations, as well as various middle schools, technical secondary schools, vocational high schools, prisons, detention centers, conference rooms, etc. Use mobile phones to cheat, send text messages, Adverse effects caused by communication with outside prisoners, collusion with others, etc.

Three, the shielded signals are diverse
Effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE.

Fourth, model advantages
1. Using high-dispersion aluminum alloy shell, low working temperature, more stable shielding effect.
2. Built-in silent turbo fan, low working noise.
3. Separate power adapter. 12V/24V DC power supply work, convenient for vehicle mobile work.
4. The antenna is externally designed, and one end of the interface is unified to make the appearance more beautiful and decent. It also has an anti-loosening design, and the antenna and the host have a marked working frequency band to facilitate one-to-one correspondence.

A major feature of the wireless signal jammer is that it is easy to carry, because it is relatively small, so when we go out, we can also carry it around, but there are other types of products around us. There are major drawbacks. Because the public products are relatively large in size and heavy in quality, they may consume a lot of manpower, material and financial resources during the carrying process, and sometimes even extremely difficult problems occur. In comparison, the reputation of household products will naturally be more ideal and more convenient.

How smart home products steal your secrets

There is no doubt that the US’s information technology strength is in an absolute leading position in the world. This strength is not only reflected in the number of information technology talents, but also in the ability to research and develop information technology, control of information resources, and influence on the formulation of information technology standards. For example, the world’s largest professional network warfare unit is in the United States; the mainstream operating systems (such as Windows, MacOS, Andriod, etc.) installed and used in the world’s computers and smart terminals are all developed and designed by the United States; the world’s main 13 root domain name servers Ten of them are in the United States…It is no exaggeration to say that the United States has the power to monopolize the world in terms of information technology. Of course, this also includes the power to invade and monitor the world.

In addition to operating systems, smartphones, tablets, web cameras and other software and hardware that are often “visited” by hackers, household products such as routers, set-top boxes, smart cars, and even smart TVs, smart air conditioners, etc. cannot escape the fate of being invaded and monitored by the CIA . Take smart air conditioners as an example. In order to improve the user experience, some manufacturers have installed microphones inside the air conditioners to collect and feedback the noise generated during the operation of the air conditioners, and use this as a basis to improve the process to improve the user experience. The CIA can use its exclusive mining (not publicly disclosed or feedback to related manufacturers) or vulnerabilities that have been disclosed but not patched in time (such as zero-day vulnerabilities) to attack smart air conditioners and ultimately gain control. Once the intrusion is successful, the microphone used to collect the operating noise of the air conditioner becomes an eavesdropper that monitors the sound of the surrounding environment, making it impossible to guard against. For another example, by invading and controlling smart cars, the CIA can tailor “traffic accidents” for some key targets, which are silent and difficult to track down. The most frightening thing is that the malware developed by the CIA can bypass software that uses cryptographic technology to encrypt storage and communication, and directly obtain your communication information. It should be noted that the “bypass” here does not directly crack the data that has been encrypted by the application, but has been monitored and acquired at the beginning of the information collection and entry (not yet encrypted). Of course, if your smart terminal uses point-to-point encrypted communication at all times, the CIA will still be unable to receive the monitored information.

So you still need to know about mobile phone signal jammer, Jammer-mart.com will be your good choice.
