The SNS suppression module is built into the REX-2 body. There is also a battery indicator, which makes it easier to control battery power.

The suppression frequency can be adjusted according to customer requirements. Video recorder, strobe, laser and aiming device are available as options.

REX-2 has completed laboratory tests and is approved for operator safety. The electromagnetic radiation rate is within the allowable range.

What needs do we need GPS jammers to meet?

Since the GPS system has been installed in place, it is of great help to us. Based on the GPS system, we have developed many devices to help us carry out military use and life. But the GPS system also poses a very dangerous threat to us, it can easily reveal our location. Anyone can easily find our location by putting a small GPS device in our car or even pocket. In order to protect ourselves from the danger of illegal tracking, we need GPS jammers. GPS jammer is an anti-GPS electronic device, which can transmit a stronger signal to cover the GPS signal with the same frequency as the GPS signal. Since this signal from the GPS jammer is stronger than the GPS signal, it may cover and hide the GPS signal, so that all GPS devices in a certain area cannot receive the GPS signal and therefore cannot work normally.

GPS devices and GPS jammers are becoming more and more popular with us in our lives. GPS equipment is very convenient to use and can cause deadly threats. It is easy for bad guys to use it to track us. This is why we developed GPS jammers-we need a safe and convenient way to protect ourselves. This GPS jammer can be used anywhere, once it is turned on, it will send a stronger signal, and all GPS devices will be unusable. However, when we turn it off, all GPS devices will resume working. GPS jammers will not cause any harm to any electronic equipment and human health.

Anti-UAV Technology Development Prospect and Impact Analysis

With the rapid development of military and civilian UAV technology, especially the successful development of reconnaissance/attack integrated UAV, the development of the “swarm” attack mode, the efficiency and cost-effectiveness of using traditional missiles and shells against UAVs The problem is getting more and more prominent. At present, all countries are stepping up the launch of strategies for UAV defense and promoting the rapid development of anti-UAV technology and equipment. Compared with missiles, the use of electromagnetic interference and lasers to counter unmanned aerial vehicles has the advantages of speed, flexibility, and high cost-effectiveness, and has attracted the attention of various countries. The successful development and testing of a batch of anti-UAV equipment in the United States and Europe has provided efficient and low-cost measures to defend against possible future drone threats.

Drone Jammer Interception System

In recent years, unmanned aerial vehicle technology has spread rapidly and widely, and a large number of remote-controlled helicopters and multi-rotor aircraft that are easy to control have appeared. Unexpected incidents related to unmanned aerial vehicles have frequently occurred, posing challenges to security and public order management. In the future, drone jammer technology will play an important role in the security field. In addition, the anti-UAV system is an emerging equipment that will help promote the development of technologies in the fields of microsystems, electromagnetic spectrum, and directed energy.

Overflying drones brings security risks anti-drone systems become the main force

The development of unmanned aerial vehicle technology has threatened the safety of many fields, especially some indiscriminate flying drones, which has brought security risks to important places such as airports. In order to be able to effectively prevent the occurrence of dangers and to effectively solve the interference of drones, Beijing Shenzhou Mingda Company has made great efforts to develop anti-UAV defense systems to protect safety and privacy in various fields. As an expert in anti-UAV systems, Beijing Shenzhou Mingda has developed various types of anti-UAV products, which are applied in various fields and scopes, and become the main force in combating unmanned aerial vehicles.

It is understood that the Greatjammer drone jammer mainly uses signal infection technology. Through advanced interference technology, the signal between the drone and the operator is blocked, and the data transmission is cut off to ensure that information is not leaked. Not only that, the Beijing Shenzhou Mingda counter-UAV system can also detect commercial small UAVs, and use signal interference technology to locate the invading UAV in mid-air, and at the same time, change the UAV’s route and target. Drive them out of defensive airspace, or prevent other UAVs from entering the airspace over areas that are prevented and controlled by counter UAV systems. The most important thing is that Beijing Shenzhou Mingda has continuously upgraded its drone technology during its development process. No matter what kind of drone it is, it will be detected by the Beijing Shenzhou Mingda UAV countermeasure system and be effective. Interference, there will never be any slipping fish. As the industry’s leading manufacturer of UAV countermeasures, Beijing Shenzhou Mingda has leading anti-UAV technology, guaranteed product quality and good interference countermeasures. It is a wise choice for all walks of life to counter UAVs.

In the future, many companies’ anti-drones will become the focus of development

Countries all over the world have accelerated the pace of development in the field of drones. Many countries and companies regard it as the most attractive piece of cake in the military industry market. Under the impetus of this cake, the development of drones will naturally mean buying drones. Become a trend. However, spears and shields are always relative terms. With the booming development of drones, some countries have also invested in research on how to counter drones. Many companies in our country are naturally not far behind, such as Beijing Shenzhou. Mingda’s anti-UAV technology is favored by many customers at home and abroad due to its excellent performance and quality. Because they have successfully solved the existing deadly threats from drones by using its anti-drone technology.

According to the official website of Beijing Shenzhou Mingda, the total sales of their company’s drone jammer sales are expected to exceed about 200 million US dollars. At the same time, the market will increase to about 1 billion US dollars in about 2-3 years. The total amount of these transactions in the global arms market is not high, but it can be regarded as the performance of a major breakthrough in the field of anti-UAV by Beijing Shenzhou Mingda. The outstanding performance of Beijing Shenzhou Mingda’s anti-UAV technology is due to a series of anti-UAV control products developed by the company in recent years. The company launched the DZ01 bag single-soldier portable low-altitude UAV control system in early 2017. , Launched the third-generation product DZ01 PRO gun-type single-soldier portable low-altitude UAV control system in May 2017, and officially launched the fourth-generation portable four-channel strike gun DZ03 PRO in 2019. The latest generation strike gun has a higher single-channel power , The interference distance is longer than the previous two generations of products (the interference distance is more than 2.5 kilometers), and the current advanced interference technology is adopted to deal with the interference of the flight control signal and the navigation signal to achieve a faster and more accurate interference effect. Really achieve long interference distance, low radiation, lightness, and simple use. Individual soldiers are portable and can achieve non-destructive precision strikes against drones from the sky!

New anti-drone guns impose order in the sky

In recent years, drones have become a rare pastime for amateurs. Now drones are everywhere, from people taking selfies, to commercial photography, to search and rescue missions.

Because of its ubiquity, accidents started to happen. The sky has become a drone infestation, and laws must be enacted to maintain order in the air, mainly in cities and airports. Due to their number and ability to carry all kinds of luggage, they have also become a serious threat to security expert review.

As mentioned earlier, it is not uncommon for drones to almost collide with aircraft, and drones equipped with cameras (or worse, explosives) may pose unique threats to the safety of the ground and facilities. However, in most cases, there are not many safe methods to deal with them.

Now, a new device that looks like a weapon in science fiction uses electromagnetic signals to knock drones out of the air quickly and safely.

drone jammer gun high power

Drone jammer guns are described as providing “safety countermeasures against various drone models.” It allows controlled management of UAV payloads (such as explosives) without causing damage to common UAV models or the surrounding environment. “This anti-drone device weighs about 8 kilograms and has an effective range of up to 1 km. It can be used on a rechargeable lithium-ion battery. As far as design is concerned, it will not be used by Stormtroopers in Star Wars movies.

It is very simple: you point the gun at the drone and pull the trigger. Transmit a series of electromagnetic signals and block the connection between the drone and its pilot. It uses radio frequencies to stop the drone from transmitting video and block the drone’s signal, forcing it to return to the launch point or land on the spot. “If the drone’s response is to go back to the beginning, this provides an opportunity to track it back to the operator.

Of course, there are other high-end technologies that can also attack aerial drones. It is an automatic defense strike system for drones.

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.

Cheap GPS jammers pose a major threat to drones

Jammers that can be bought for as little as $ 50 threaten commercial drones, but options exist.

With the rotors buzzing and the airframes racing through the air, drones can be very dangerous if flights don’t go as planned. Much has been gnawed about the FAA’s measured approach to implementing commercial drone guidelines, but the fact is there are real dangers, even from bad actors using inexpensive GPS jammer.

GPS signal jamming technology is evolving, decreasing in size and cost. These days jammers can be bought online for as little as $ 50. Jamming has long been a threat to military assets and is becoming a commercial problem today as commercial drone shipments become a reality and attacks become ubiquitous around the world. This threat now affects trade, law enforcement, and defense drones on critical missions.

During a choreographed light show in Hong Kong in 2018, 46 drones fell from the sky due to a jamming device. The resulting property damage and loss of hardware is estimated to cost an estimated HK $ 1 million. Almost all drones have security protocols that can be used to send them home or to a safe landing site in the event of a disruption. However, these functions were found to be ineffective at the Hong Kong show.

“These are professional-grade drones already built with technology that will guide them back to the launch site,” Anthony Lau Chun-hon, director of the events committee, told the South China Morning Post. “But the signals were so strong that many of them just fell out of thin air.”

Drones and their services are decidedly dependent on GPS signals. Although the drone may have backup methods (INS / OPS), GPS references are still required for positioning, navigation and stabilization. GPS attacks are therefore the easiest way to shut down a drone and potentially cause harm to life and property.

The good news is that solutions for drones are arriving with commercial quality and coming straight from the defense sector. One comes from a company called infiniDome, which makes a device called a GPSdome that is built into a drone’s GNSS receivers and uses a unique interference filter system that combines the patterns of two omnidirectional antennas. GPSdome analyzes the interference signal in real time and feeds its properties into infiniDome’s proprietary algorithm to filter and reject attacking RF interference, so that the UAS continues to rely on GPS signals during a jamming attack. If an interference signal is detected, the GPSdome notifies the operator of possible signal interference.

Easy Aerial, a leading provider of autonomous, drone-based surveillance solutions for commercial, government and defense applications, recently added GPSdome to its range of autonomous unmanned aerial systems for military use.

“We chose GPSdome because it was a proven solution that was a perfect fit for the various missions our customers routinely fly in some of the most inhospitable and hostile environments in the world,” said Ido Gur, Co-Founder and CEO of Easy Aerial. “While our systems have multiple redundancies on board, GPS signals for maintaining position, navigation and timing accuracy are critical to ensure uninterrupted operation.”

This type of lightweight, small form factor, low power shielding technology is a critical step towards widespread adoption of commercial drones. Other companies like Sepentrio also take GPS interference in drone applications with integrated sensor solutions seriously.

It is certain that the problem of GPS interference and spoofing will receive more attention in the coming days. Fortunately, developers seem to be beginning to see tools that they can use to counter the growing threat.

What should I do if I am tracked by cell phone signals?

China now has a lot of cell phone signal jammer, but what would happen if China did not have a mobile phone signal booster? Most of the mobile phone signal booster technology is not up to standard, resulting in a serious decline in the overall signal quality of many urban villages. It is because of this type of equipment that the mobile phone signal amplifier products are notorious. The actual data interferes with the base station and affects the neighbors’ equipment. It is just that people have a habit of doing well. If there is a problem, it will be spread.

Although the mobile phone signal amplifier has produced many negative effects, the positive effects are even greater. In my basement, there is no signal to solve by myself. Your own company has just been renovated, and you can solve it yourself if the signal is not enough. Any environment where the signal cannot be resolved in time can be resolved with an amplifier.

GPS interference had a serious impact on the war

When the Iraq War broke out in 2003, the Iraqi army used a Russian-made GPS signal jamming system to destroy the US military’s guided weapons system, creating a sensation. South Korean military officials are doing their best to develop countermeasures, fearing that the equipment could cause similar damage to the South and its allies in the event of a war.

GPS jammer is so sensitive that they also cause accidental interference. In one case, a VHF / UHF TV antenna preamplifier in Monterey Bay, California generated three or more interference signals. The signal strength of the preamp is sufficient to push the GPS completely into a radius of 1km above sea level. The authors of the report speculate that similar sources could interfere with aerial GPS receivers within 50 km if transmitted using omnidirectional antennas.

Long-range air-to-ground cruise missiles, including Tomahawk cruise missiles, are also GPS-guided. The advantage of GPS-based weapon systems is that they can accurately attack targets despite bad weather and complex terrain. Their drawback is that even weak signals can easily get stuck.

Seoul told North Korea in a letter issued Monday that since March 31, North Korea has blocked GPS signals in South Korea, threatening the safety of civilian aircraft and ships, and violating international agreements. Told.

South Korea’s UN ambassador, Oh Jun, said electronic mobile phone signal interference signals from five regions of North Korea (Heju, Yang An, Pyongyang, Jin Jiang, and Kaesong) “dangerously affect GPS.”

The South Korean government reported that North Korea had imported about 20 communications and radar jammers from the former Soviet Union. The in-vehicle device was reportedly deployed near the border and interfered with GPS signals within a range of 50 to 100 kilometers.

A few years ago, when satellites were advertised as the only navigation method in the aviation industry from takeoff to landing, former FAA administrator Langhorne Bond painted a dark winter night on the east coast. The weather is below the limit. In that case, terrorist GPS interference could be a “weapon of mass destruction,” he said. The FAA considers this an unfounded guess. However, in a recent report on GPS-dependent ADS-B, DOT inspectors took the issue more seriously and called on the FAA to “work with US intelligence to assess this potential threat.” I did.
