U.S. Army tests could not stop the new GPS last fall

Last fall, after Russia was suspected of jamming GPS signals in Europe and elsewhere, the U.S. Army will test an anti-jamming GPS to solve the defense breakthrough problem.

GPS jammer can also pose a major threat to the United States and allied forces, and everything from troop movement to guided missile and UAV guidance depends on the system. Last fall, the United States and NATO allies launched a large-scale joint exercise called Trident Juncture in Norway to test the joint preparations and training of a large multinational alliance. During the exercise, the military noticed that GPS signals interfered with signals attributed to Russia by Finnish and Norwegian officials. In April 2018, US officials stated that the Russian military had blocked the GPS system of UAVs used in Syria.

Members of the German Second Cavalry Regiment will be equipped in the fall. According to reports, the Army is considering developing a new generation of inertial navigation system that can be used as a backup system.

At the C4ISERnet conference in Arlington last week, Colonel Nickolas Kioutas, project manager for Army procurement developer Positioning, Navigation and Timing (PNT), said that it’s important to deliver equipment to troops quickly, and the Army is working hard to roll out the Equipment used in the iterative process. Breaking the defense points out that by putting the system in the hands of units like the Second Cavalry, the Army can quickly evaluate technology and make improvements if necessary-without spending years developing and testing equipment that turns out to be the wrong one.

Explosion proof of jamming device at gas station

In many countries, cell phone signal blockers were suitable for stopping calls at gas stations. Purchasing a modern and fashionable cell phone signal blocking kit is the latest and most wise advice for cell phone users and service station personnel.

The use of mobile phones is a danger of explosion at gas stations. Turn off your cell phone while filling the car. There are usually warnings about banning mobile phones at gas stations. In many countries, cell phone signal blockers were suitable for stopping calls at gas stations. Buying a modern and trendy cell phone signal blocker kit is the latest tip for cell phone and gas station users. Recently, we have informed all affiliates to pay attention to those who pay for gasoline. Cause an explosion. Come here for professional online store jammers to get back powerful signal jammers and avoid unnecessary dangerous opportunities. You need one at the service station. You know there were some explosions due to the phone being used at the service station. You can now stop the dire fate with mobile jammers.

According to media reports, Indonesian drivers were severely damaged by static electricity from their cell phones, which ignited gasoline vapors, causing burns. Very terrible To protect yourself from danger, you need to install a high power cell phone blocker. The threat that mobile phones pose to service stations and their users around the world is primarily due to their ability to generate sparks. To stop the sparks, our stones have produced many sabotage products for your picking. Some people, especially teens, are unaware of hidden threats and easily forget warnings when at gas stations, so they easily fall into their cell phones for these reasons.

Now it is your mission to buy better cell phone signal blockers to avoid the tragedy. So what do you do? Get it now.

Mobile phone shielding device selection guide for examination rooms

By the annual exam season, all parties have begun to prepare for the exam, and the invigilator has various tricks to prevent high-tech fraud. Among them, the shielding device used in the examination room is still an anti-fraud shielding device. However, Chengdu Saiyue Communication reminds that there are many types of shielding devices, and users should clarify their needs before purchasing them to avoid test room accidents due to poor shielding effects, and pay attention to the correctness of the method of use.

First of all, I want to clarify the place of use. Most schools use test room-type mobile phone shields that are suitable for long-term work and are durable. The second is how big are we in the shielded area? For example, if it is a room of 100 square meters or a venue of thousands of square meters, if the area is large, the power must be larger, and if the area is small, the shielding power must be considered small. Then there is which frequency bands need to be shielded. Are all China Mobile, China Unicom, Telecom and CDMA shielded? Still only need to shield part of the frequency band.

Phone Wifi signal jammer

At this time, we remind everyone that if you want to buy a suitable shielding device to achieve the effect, it depends on the method used. The main points are as follows:

1. It is recommended that the indoor shielding device be placed at a height of about 180cm-220cm above the ground, with a forward angle.

2. Whether there are obstructions (such as walls, metal products, etc.) between the wireless jammer and wireless communication equipment (mobile phones, etc.). The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to avoid it.

3. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shielding device.

4. The farther the jammer application environment is from the signal tower, the stronger the theoretical shielding effect of the jammer.

Why military jamming technology is needed?

Russia’s accumulated intelligence and electronic warfare tools also include the deployment of Krasukha-4, an advanced electronic warfare system used to destroy radars and aircraft. Sputnik News reported on its presence in Syria, and the country claimed to have discovered a unique GPS jammer system in a video report of a Russian jet at Latakia Syrian Airport. The system and its parabola are shown with a 6-second mark in the video below.

Since the invasion of Iraq in March 2003, a series of active, passive, weekly and powerful saboteurs have arrived in Mesopotamia: Warlock Green, Warlock Red, Warlock Blue, ICE, MICE, SSVJ, MMBJ, Card brand. Dunwood, Juke Box (Symphony) now collectively refer to them as CREW. This is a clumsy acronym for an acronym. The improvised explosive device conducts electronic warfare against the jammer.

As more and more military turmoil floods the theater, the turmoil becomes more and more chaotic. Over the past few months, the Army and Marine Corps have clearly realized the shortcomings of electronic warfare expertise. Major Arch Messi, the commander of the Naval Surface Warfare Center, said: “We put all these boxes here, but people don’t know how to use them.”

This is especially true in Baghdad, where the electromagnetic environment seems to change with the community, the season and the time of day. A Pentagon executive said: “No one knows how much interference will occur on the ground.” This is the interface between the earth and the air at the intersection of the earth and the sky. The Army logistics staff added: “I don’t know that taxi drivers usually make electronic noises, doorbells, garage door openers, and satellite communications because they have not scientifically identified the problem. This is a normal life plan.”

Camouflage portable cell phone jammer

Even for North Koreans, GPS jammer is nothing new, but the latest tests are certainly rare. If there is no ground interference, it may indicate that the device is in the air, but since the FAA only covers airspace, ground interference cannot be ruled out.

In fact, interference may just be a test bed for new anti-jamming technologies that are under development and costly. As the ability to jam GPS every day becomes easier and cheaper, the military is actively developing new systems to enable aircraft, drones, and missiles to withstand jamming signals.

Portable jammers are more complicated than desktop jammers

It is said that GPS tracking equipment is usually installed on a part of the car. Some people are afraid of GPS. The most common GPS threats in life are common. You can now see that jammers are used in many places. By emitting interfering radio waves of the same wavelength as the radio waves of GPS satellites, the GPS positioning function may be hampered. The radio waves emitted by the equipment that I have confirmed are very weak and in the weak radio wave range defined by the radio law. Some equipment is suitable for cars. There is a car loading design.

Portable Mobile Phone Jammer

This is a device capable of blocking radio waves to the car’s GPS receiver. They say GPS jammer is on the market. If the device freezes, the phone will be out of range and the phone cannot be used. There is a handy GPS circuit breaker that supports these devices. A car charger is also included, so you can charge while racing. Within seconds, navigation cannot be done like GPS. Determine the ability to receive obstacles. Even if the output is small, interference may occur. The phone is convenient because you can do all kinds of things. You have to understand that this is advanced tracking technology. There are currently many GPS tracking apps with location tracking capabilities. It usually goes unnoticed, just like being watched by someone all the time. Personal confidentiality may have been disclosed. Some interfering devices may avoid tracking. The radio waves from the smartphone may be cut off. The mobile jammer has a high power design. There is a strong range of interference.

Signal blocker in the toilet

Recently, my colleagues in the unit have found that the problem of toilet access that has plagued everyone for a long time has been solved well. Almost no one will stay in the toilet for a long time and look at their mobile phones. There are a lot of squat pits empty. There is no queuing to go to the toilet.

This was not the case before. If you want to go to the bathroom, you have to wait in line. If you can’t wait, you ran to go to the bathroom. Just because of this, the leader had a headache. He talked about it many times in small meetings. The effect It is not so obvious, and the problem of difficulty in using the toilet has not been fundamentally solved. In order to avoid going to the toilet as much as possible, some colleagues simply solve it at home, drink as little water as possible, and reduce the frequency of going to the toilet.

It’s not that there are fewer squats. The crux of the problem is that now the mobile phone signal is strong. When some people go to the bathroom, they watch or play games with their mobile phones. This squat is for most of the day. It’s a long time, but the people waiting to go to the toilet are different. It is very uncomfortable to hold back.

In order to completely solve this problem, the leader asked everyone to brainstorm. In the end, either lacked operability or was too expensive to be worth doing. There was a person’s idea that attracted the attention of the leaders.

A powerful jammer

This person’s idea is very simple. Install a signal blocker in the toilet. If there is no mobile phone signal or the signal is weak, how can people who go to the toilet squat in the toilet for a long time? The squat will be empty.

So, the leader installed a signal jammer in the toilet just as the person said, and the effect was immediately apparent.

It is much easier to find the key to the problem and catch the bull’s nose.

Mobile jammers confuse operators and manufacturers

The unwanted ringing of telephones in the middle of a movie or concert, soon more than a bad memory? Industry Minister Patrick Devedjian definitely hopes that. On October 10th, it issued an order authorizing the installation of “cell phone blocker” to disable cell phones in theaters and cinemas.

This ends more than three years of floating. Because the law of July 17, 2001 (which establishes various provisions of a social, educational and cultural nature) “allows” this type of disturbance “both for emission and reception (…) in the enclosure of the theater. The regulator for Telecommunications then issued a decision to “establish, at a technical level, the regulatory requirements for the use of these devices.” This decision, which was sent to the Ministry of Industry in late June 2003, had to be approved before it could be applied.

This is what Patrick Devedjian has just done, concerned about the “catastrophic impact” mobile ringtones could have “on the revenues [of the cinema operators] and therefore on the film’s bottom line,” he added. he explained on the France Info microphone. Installing such filtering or jamming devices will be the responsibility of cinemas, theaters and concerts, he said. Remember that since September 9, 2002, the Judiciary Orientation and Programming Act also authorizes GSM jammers in prisons.

The icing on the cake for cinemas
In a press release, however, the minister recalled two principles that power halls and manufacturers are obliged to adhere to. On the one hand, “jammers must not cause the success rate of calls outside the room to deteriorate.” On the other hand, their “location must not stand in the way of the application of the regulations applicable to emergency calls”.

This measure enthused Jean Labbé, President of the National Federation of French Cinemas. At France Info’s Airwaves, he welcomed this decree, which “is the result of a long request [from] extremely diverse cinemas, ranging from large to small exploitation”. For him, “the jammer approval is icing on the cake” after efforts and investments have been made to improve the comfort of the rooms.

Others are far from sharing this enthusiasm. “It is a radical decision,” one of the three mobile operators told ZDNet. “These cuts can create security issues and urgent objections.” In 2001 all operators had unsuccessfully applied for the withdrawal of this measure during the ART consultation on this issue.

Challenge from Brussels and several EU countries
Same story at Orange: “Good communication is enough to curb the problems of good manners in theaters,” said a spokesman. As evidence, he said: While the number of cellphone-equipped customers has doubled in a few years, inappropriate behavior has not necessarily increased.

The operator is highlighting the “Citizens’ Campaign” that has been running for several months with posters to encourage customers to switch off their cell phones or let them vibrate on trains or in cinemas. And is concerned about possible overflows from these filter devices: “Who knows if this won’t cause problems with the neighbors upstairs or with people on the street?” Asks the Orange spokesman. France.

Henri Asenkat, President of the Association of Manufacturers and Industrial Companies for Cellular and Professional Radio Communications (Acirp *), also reiterates his opposition to the process. “We had long conversations with ART to explain to them that we are not cheap because of the ethics of the manufacturers who want us to network,” he said.

“We also claim that this is against European regulations.” In 2001, these manufacturers tried to convince ART that this provision violated several European directives (**) with no result. Despite several detailed comments from the UK, Denmark, Finland and the Commission itself contesting the jamming principle, the regulator sent its decision to the Department of Industry in June 2003.

Signal interference in teaching area during teaching management

With the increasing popularity of mobile phones, the status quo of students using mobile phones has even reached a large number of elementary school students, and the proportion of middle schools and high schools is even greater. At present, although various schools have clearly stipulated that teachers are not allowed to receive and call mobile phones during class, and students are also required to turn off their mobile phones or adjust their mobile phones to vibrate by themselves, but due to students’ self-discipline and self-consciousness, they have been giving schools daily teaching The management brings constant trouble! such as:

There will always be some students who forget to turn their mobile phones to vibrate for some reason, and a sudden call or text message during normal class, especially when some funny and tricky sounds sound, the originally quiet class and normal teaching will be interrupted.

Some students who are unconscious in class have the function of text messaging on their mobile phones. If they don’t want to attend class during class, they don’t need to whisper to the next desk to chat, just send and receive text messages on their phones.

Today’s mobile phones are equipped with Internet access, and students can frequently use their mobile phones to chat, read novels, and play games during class.

The school installs and uses the cell phone signal jammer device intelligent management system to prevent students from using their mobile phones excessively during class. However, when the mobile phone signal is shielded in the classroom, some students will say that the school violates the student’s “right to freedom of communication”. From the standpoint of students who frequently use mobile phones, these views seem reasonable, but if you think about it more seriously, if blocking the mobile phone signal infringes the students’ communication rights, then these students use mobile phones in classrooms or self-study. Have you ever thought that you violated the right of other students to receive education? Have you ever thought about respecting the teacher’s teaching authority? Whether right or freedom, there are only relatives, not absolutes. Any rights or freedoms are based on respect for the rights of others. The laws of our country are also rules based on the interests of most people. This rule protects the rights of most people. If you really want to talk about infringement, it is that a small number of students who use mobile phones freely regardless of occasion infringed on the education rights of most students.

Powerful signal jammer device

Some students or their parents may also suggest that the school has blocked mobile phone signals during class. What if there is something urgent in the family to contact or fail to notify the students themselves? In fact, this question is not difficult to answer. First of all, from the perspective of students, the reason why students use their mobile phones is to make contact with their parents convenient. In fact, students are in school, as long as there is no emergency, they don’t need to be on 24 hours a day. In case of special circumstances, the school, the teacher and the parents will take the initiative to contact. Secondly, from the perspective of parents, just remember that since their children were equipped with mobile phones, there have been a few times so far because of special circumstances. If they had to make a phone call, they would immediately stop learning in class and leave school to deal with it. of?

Moreover, the school has installed the campus mobile phone shielding device intelligent management system. It does not shield students from their mobile phones for all the 24 hours in the school. It only shields students for 40 to 50 minutes in the morning and afternoon classes. Shielding, even the ten-minute break between classes will restore the cell phone signal. The mobile phone jammer intelligent management system has fully considered the humanized shielding of students’ mobile phone signals.

Talk about the summary of experience when installing jammers in prisons

A. Most prisons have guard towers and observation towers to protect prisoners. The height of the towers is mostly higher than the prison buildings. If the antenna height is higher than the tallest building, it will be easier to block cellular phone signals in the air. Therefore, it is very easy and more protective to install the prison shield on the observation tower. Moreover, engineering costs can be greatly saved. The installation process can be improved.

B. If there is no prison guard tower or its use is not allowed, we suggest that you can choose a fence. If the height of the wall is higher than the tallest building, solution a can be used. If the wall is lower than the tallest building, a fixing bracket must be installed on the wall. The height of the support must be 3 to 5 meters higher than the tallest building in the prison. The higher it is, the easier it is to install the antenna. In this way, the construction cost will be higher than solution a. If it is a larger prison, more shields must be installed to adopt solution a and solution b. We recommend installing wireless jammer with omnidirectional antennas on some buildings in the middle of the prison to increase the shielding range and reduce the amount of interference.

C. If all guard towers, prison buildings and fences in the prison are not allowed, we must recommend the construction of some fixed cylindrical towers or signal towers. Engineering costs will be more difficult and expensive. The whole building will be much slower. To some extent, once other solutions cannot be adopted, this is our last choice.

Tip: If you use plan B and plan C, please pay attention to install lightning rods. The height of the lightning rod must be 2M higher than the antenna. jammer-mart has many years of experience in the installation of signal jammers in prisons. It is also very experienced in projects in other places. At the same time, you can choose the jammer products that suit you on our website.

Safe and legal use of frequency blockers

More and more people are concerned about their privacy. Recently, in the United States, Facebook users have stolen private data, causing people to think on different levels. We all know that many new wireless devices can steal our personal information, even we don’t even know.

We use different devices every day, including GPS navigators, laptops, laptops and smartphones. But many people don’t even know that male factors will steal their personal information, and their wireless devices are their dual agent.

We use Wi-Fi connection, but we don’t know how easy it is to hack. We use Bluetooth, but we have never heard of bluesnarfing. Of course, we use GPS to know where we are and how to get what we need, but have you heard of GPS navigators?

From this perspective, I understand why these mobile phone jammers are very popular in many countries around the world. They are usually used for protection because people want to protect their privacy and the privacy of people who care about them.

As I said before, these jammers, GSM signal blockers or mini gps jammer have been used in many countries/regions in the world. But if you read about these painful ways of working, it will be better. Another important information is the frequency of the interference signal used. Many people use these signals for rate jammers, so I tried to find some simple principles for using jammers safely without harming anyone.

gps car signal jammer

In the United States, there are no restrictions on the use of interfering devices, but transmission on certain frequencies is prohibited without permission. But I believe that if your privacy or the privacy of the people you care about is at risk, then all means are sufficient. But you must remember that we must not forget the rights of others. There are some simple principles for safely using jammers.

1. Do not use jammers in public places. We recommend that you use private interference devices. Do not open it in public places, otherwise it will hurt others. You can freely use the jammer in the car or at home. In addition, please try to choose a jammer that matches your work space, because some of your neighbors are in areas where there is no signal.

2. Protect your privacy without disturbing others. You must remember that other people want to communicate freely. Don’t try to make her sad. Remember that if the jammer is on, no one on the phone will ring, not even 911. Do not use jammers in police stations or hospitals near cars.
