US federal authorities announced a new drone directive last month: Entertainment drone operators must register their aircraft. The measure will largely manage and regulate entertainment drones, and registration will help operators understand the rules and be accountable to the public, flying irresponsible uavs, and understanding the consequences of flying hazards.

Drones have more users and enthusiasts, and these newcomers ignore the rules, which requires a certain level of training and harms aircraft in national airspace. UAV jammer will send radio frequency waves to prevent the connection and maintenance of equipment within range. After the remote jammer detects the drone signal, it will force the drone to land or return.

China’s self-developed UAV jammer looks strange like a chainsaw

The first is discovery. Almost all current large-scale advanced drones use stealth design, which makes it difficult to discover their whereabouts. At this time, the long-wave radar is used. The current stealth drones are mainly effective for centimeter-wave radars, but for long-wave radars, drones are almost impossible to stealth. Long-wave radar can provide early warning and azimuth indication for stealth drones, laying the foundation for subsequent strategy development.

The second is interference. Utilizing ultra-high-power drone jammer to transmit strong electronic waves to the UAV, blinding the UAV’s radar, cutting off the “umbilical cord” connection between the UAV and the space-based satellite and parent base, making it unable to receive remote control instruction. * Is to take over. When the UAV’s accusation command is interfered by strong electronic waves, it will retransmit a fake GPS parameter to the UAV to make it fly according to the path desired by the trapper, and finally control it to land smoothly to the designated location.

drone jammer gun high power

However, the theory is so, but in fact, because the enemy UAV also has information encryption and anti-interference methods, it is not easy to operate. All military powers are sparing no effort to develop technologies that can “trap” drones. For example, Russia’s “automobile field” is one of the few electronic countermeasure systems that can “trap” advanced drones. It consists of dozens of vehicles, loaded with radar, electronic jamming equipment, and ground command equipment, which can easily penetrate The enemy’s electronic jamming waves and avionics resistance.

Drones are causing trouble again

From 6 am to 6:30 am local time on May 14, Saudi Aramco’s pumping stations 8 and 9 were attacked by drones, and the company was forced to temporarily close the east-west pipelines. The Yanbu Port that was attacked this time was even more than 700 kilometers away from the Houthi armed forces’ control area, and the ASEF-1 small drones currently in the hands of the Houthi are simply not enough to support such a distance. Voyage. The only explanation is that the attack was caused by a Houthi-armed drone attack squad that penetrated the border between Yemen and Saudi Arabia and carried out a long-distance attack.

Affected by this incident, international oil prices rose sharply during the intraday session, and the intraday increase once exceeded 1.5%.

In March of this year, the Houthi UAV has publicly reached an important strategic goal in southern Saudi Arabia: Suqa Phase 2 of independent desalination and power plants. Compared with the last reconnaissance operation on Suqa Plant 2, the attack on Yanbu is even more shocking, which is too far away from Yemen. Yanbu is located in the central area of ​​Saudi Arabia’s Red Sea coast. The closest distance to Yemen is more than 800 kilometers. The range of small drones in the hands of Husseis is not that far. For such a long-distance flight, at least a medium-sized drone of the level of Rainbow 3 is required. The flying distance has exceeded the direct communication distance between air and ground. Satellite relay communication equipment is required to ensure the communication between the drone and the ground station. Because of the Houthi armed forces’ equipment level and organizational capabilities, the take-off point for this attack cannot be in Yemen. Either take off from the sea, or secretly infiltrate and take off near Yanbu. Obviously the former is the least difficult to implement.

The seven UAVs used in the attack were QASEF-1 suicide UAVs in the hands of Hu Sai. The pictures and information of the aircraft that Hu Sai has shown to the outside world are based on Iran’s Ababil-2 UAV. The maximum flight distance can reach 150 kilometers, the length is 2.5 meters, and the wingspan is 3 meters. Small fishing boats can carry it. . It is very likely that the fishing boat controlled by Husai sailed concealedly to the sea off Yanbu Port. The 150-kilometer voyage can ensure that the ship is on the high seas. The total weight of the warhead carried by the 7 QASEF-1s is 210 kg, which is enough. Two carefully selected pumping stations caused serious damage.

This shows the touching degree of the combat power of the Saudi “Royal Army”. First of all, the borders of their homes were infiltrated by the armed men of the other side without even knowing it, and they were allowed to run hundreds of kilometers in their own territory. What’s more, Iran’s aid to the Houthi armed forces has been significantly reduced after the sanctions. This can be said to be a wave of high-profile UAV counterattacks by the Houthi armed forces against Saudi Arabia under desperate conditions. Saudi Arabia, whose annual military expenditure is as high as 67.6 billion U.S. dollars, has nothing to do with it!

It’s time to consider using drone jammer to counter drone.

Why drones become a nightmare at British airports

London’s Gatwick Airport (Gatwick Airport) has been closed for more than one day under the influence of drones, affecting more than 700 flights and affecting approximately 100,000 passengers. The local police have yet to find anyone operating the drone, but they suspect that it may be the work of environmentalists.

A Gatwick Airport spokesperson pointed out that the British police and military have provided additional precautions for the airport to allow the airport to reopen and allow aircraft to take off.

Many drones are now cheap, and you can buy them for as little as tens of dollars. But the BBC science and technology reporter Jane Wakefield (Jane Wakefield) reported that these small aircraft can have a huge impact on civil aviation traffic.

What is the impact of drones on aviation safety?

A UAV collided with a civil airliner at an airport in Canada in October 2017. The wing was slightly damaged, but it still landed safely afterwards.

We are not yet fully aware of the consequences of a collision between a UAV and a civil airliner. Many organizations have done relevant research to simulate the consequences of collisions between drones and passenger planes in different situations, but the conclusions of each test seem to be different.

The University of Dayton in the United States simulated a collision between a one-kilogram drone and a civil aircraft flying at 383 kilometers per hour. The results showed that the passenger aircraft was seriously damaged.

If there is a drone jammer gun, will the situation be better?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type. The principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range. The operating distance is within 1000 meters, which can force the long-distance low-altitude drone to fall, return to the operator or descend smoothly in a short time, thereby realizing effective control of flying drones in the “control area”.

What are the main applications of anti-UAV systems

According to its product manual, the anti-UAV system allegedly uses signal jammer on 2.4 and 5.8 GHz frequencies. It also has technology that can block GPS and the Russian equivalent of GLONASS.

By the end of 2017, the long-range automatic anti-UAV system provided by Shenzhou Mingda can provide the detection range of a small drone like the DJI phantom, up to 5 kilometers, 360-degree panoramic coverage, no blind spots and visual tracking capabilities. Identify and eliminate drones up to 2 kilometers away. The system is composed of advanced military radar, advanced long-range EO/IR visible and thermal infrared day and night PTZ surveillance camera system and powerful broad-spectrum RF and GPS signal jammer. . This automated system will provide 24/7 detection, tracking and elimination of drones/unmanned aerial vehicles, with the option of static jammers for permanent installation, making it a high level of mobile, perimeter security, activities, airports, and rural and urban security Ideal choice for value goals. Threats up to 10 kilometers in diameter.

There are many systems that can be used to land willful or dangerous drones, but they often have a big gain: you need to be relatively close to the drone, which can be scary if the robot plane is loading explosives. It is launching a drone strike gun, a jammer that can disable drone signals (including GPS and GLONASS positioning) from 1.2 miles away. Like most competitors, it will not destroy the target drone-it simply forces the vehicle to land or return to its starting point. Anti-drone teams can not only disable threats from a safe distance, they can also locate their pilots.

The authorities have now begun field tests of their new anti-drone “gun”, which can shoot down any unpopular drone. The police used a new drone jammer in a recent large football match. Any drones that intrude into the competition venue are banned and forced to land via the signal interference capability of the system.

According to reports, the new jamming system is able to capture the target from a kilometer away, which gives it enough range to eliminate the incoming air threat before it arrives. The authorities are taking these types of threats seriously, which is why they may buy more units for different police agencies in the country.

Anti-drone technology is necessary in the future

Anti-UAV technology, why is it essential for airports.

With the dramatic increase in drone penetration in the past few years, controlling the sky above us has become an additional responsibility. UAV detection solutions have become very important, not only can detect long-distance UAVs, but also access a variety of potentially important information, such as controller location and UAV model.

Who are those organizations that rely on drone detection? The police force certainly bears a great deal of responsibility when tracking illegal activities involving drones, but the airport (probably more than any other type of venue) must fully control the sky above its location. As drones increasingly enter the airspace around airports, this reality has become more relevant in recent times.

Last summer, a drone entered the airspace near Gatwick Airport, causing five aircraft to be diverted and completely closed the runway.

In addition to endangering the safety of passengers on board, taking up air traffic control time, and causing inconvenience to people who eventually misplace or put their journey on hold, it can be said with certainty that the interruption of drones will eventually cause great losses to airlines. All these problems are caused by a relatively small unmanned aerial vehicle, which emphasizes the importance of airport drone detection.

According to this BBC article, the British Airprox Commission conducted an investigation into the Gatwick incident and concluded that the incident caused as many as 130 deaths.

Time for action

The truth is not a lie. According to Airprox’s data, in the last two years of records, 168% of aircraft errors on drones and aircraft. The drone caused chaos around the airport, stopped flying, almost lost the aircraft and caused delays.

In December 2018, a drone report at Gatwick Airport grounded all flights and disrupted thousands of passengers within 24 hours. Fortunately, there is a solution to these problems and return more control to those who work on the ground.

UAV automatic detection and defense solutions can let people know those who pay attention to the sky. UAVs can now be detected up to 20 kilometers away, and early warning can give precious time to prepare and deal with any type of UAV threat.

drone jammer gun high power

The ability to identify the location of the controller gives the airport the opportunity to more effectively liaise with law enforcement agencies to take action against those who violate its airspace. It can identify a specific drone model and the actual serial number of a single drone that has been detected. This is enhanced by the flow of information to be able to pinpoint the heading, speed and altitude of the drone-all potentially key facts that could affect the actions taken by air traffic control.

Portable drone jammer has become a popular anti-drone technology option, suitable for police forces that require drone detection on the move, but when it comes to airports, the fixed version may see the most demand .

Talking about the advantages of UAV jammers

Today, more and more people complain that their personal lives are often exposed to unauthorized drones. UAVs are very famous today, they are usually used to capture important events or certain objects from the air. Since these technologies do not stand in the same place, new and more advanced models of drones and squares are being created every day that can turn your personal life into the object of particularly curious espionage.

Intruders are one kilometer or more away from objects protected by traditional security systems. They can conduct industrial espionage from the air, monitor private life, throw prohibited items around guards or export valuables, and drugs bypass control points and inspections. Considering the growing threat of terrorism around the world, the use of drones carrying explosive devices can be expected to attack crowded locations and sensitive infrastructure elements. Equally dangerous is the drone, whose operators simply lose control and stay away. Such drones are in the airport area even at very high altitudes, and can enter the engine of the flying or landing aircraft and turn off the power cord.

Thieves can obtain detailed information about the location of guards and installed CCTV cameras, the location of storage facilities, and the number of any secret equipment. As you can see, with the help of drones, detailed information can be obtained. Therefore, if you want to protect yourself from unauthorized entry into your personal life or business, then you should know what drone jamming technology is. The jammers of quadcopters and drones are high-power devices that can block the audio and video transmission of information. These devices are beneficial because they can store confidential materials.

When choosing a drone jammer, please pay attention to the spectrum of the blocking frequency. The drone jammer is a powerful device that can effectively prevent the operation of the following frequencies: video transmission frequency (2.4G WIFI 2400-2500MHz 20W); remote control frequency (2.4G WIFI 2400-2500MHz 20W); ˚F video Transmission and remote radio control (5.8G 5.5-5.9MHz 2W) rate; ˚F remote radio control nuclear rate (868-912 MHz, 860-920MHz 25W, 20W 433-434MHz); GPS frequency L1 1575 MHz 40W.

The anti-drone jammer is equipped with multiple pin antennas. The length of the antenna can be different. The blocking radius of the suppressor can also vary according to the signal strength, location, and remoteness of the basic control. The more powerful the function you choose, the larger the blocking radius. It is important to note that the jammer has a low-noise built-in fan. With such a reliable cooling system, you can stay calm and overheating will not pose a threat to you.

Most drone radio jammers have unlimited working hours, so you can use it for a long time. Signal jammer is specifically used for advantageous purposes to ensure control of the territory, prevent industrial espionage, counter-terrorism purposes, attempts to move narcotic substances, certain types of weapons, personal family information or commercial espionage, etc. 2.4 GHz jammer for drones-ideal for any citizen who cares about privacy. If you have any questions about drone blockers, you can call our manager or send a message. We are happy to answer all your questions. In addition, we will help you choose a suppressor that meets all your requirements.

A hundred shots and a hundred hits within 2000 meters, the drones dare to fly randomly?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type.

The Wuhan police demonstrated that they are equipped with the latest domestically-made “electromagnetic rifles.” In the opening match of the China League One held last week, a drone of unknown origin broke into the event site, seriously disrupting the progress of the game. Afterwards, the Wuhan police took out their new equipment-a silver-gray drone counter-gun about 1 meter long, and “shot down” the opponent with a single shot. On the day of the match, the Wuhan police used the gun six times to expel the approaching drone.

portable drone blocker gun-type

The drone was not broken into pieces, but landed slowly on the ground. According to the International Business Times, the principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range.

This drone jammer uses a combination of an integrated information source and a broadband power amplifier, and the source integrates 8 frequency bands. The full frequency band coverage of radio from 300MHz to 6GHz is closer to the current mainstream UAV radio remote control and image transmission signal modulation method. The intensity of electromagnetic waves it emits is 8 times that of ordinary jammers. It can accurately distinguish various drones at a distance of 3 to 5 kilometers, and effectively intercept within a range of 500 meters to 2000 meters.

The conference hall shields the mobile phone signal, this can have

Some cadres complained that during a meeting, the conference hall would turn on the mobile phone signal jammer to block the mobile phone signal. Once they entered the conference hall, they were completely “lost” and were very uncomfortable. Some people think that this is “a delay”, saying that they have been complained by the masses because the mobile phone cannot be reached. Some people even directly asked: Is it necessary? Have a meeting and leave the phone temporarily, is it really that serious? Nowadays, the mobile phone has become an “external organ” of modern people, regardless of whether it is on the way to work, at work, or at a party, it is in the state of “people do not leave the machine, the machine does not leave the hand”. The latest survey shows that Chinese people look at their mobile phones for an average of 3 hours a day, making them the second most addicted person in the world.

portable wireless signal jammers

People’s attention is severely distracted, time is cut into fragments. Not to mention the whole time of a meeting, even if it is more than ten minutes without looking at the phone, many people are not at ease. Some netizens describe that the most painful thing today is not “the distance between life and death” but “the phone has no power, no internet, no signal.” In a conference that should be serious and efficient, we are also used to seeing too many “head down landscapes”: he is using his mobile phone when setting up work on the stage; he is using his mobile phone to convey the spirit on the stage; Cell phone. Really busy managing everything, can’t stop for a moment? Closer to see, there are not many electronic offices. Most of them are browsing Moments, or even visiting online stores and playing games. If you want to portray these people, it is more appropriate to “read only the mobile phone screen and ignore the meeting.” Of course, it is difficult to put into the meeting agenda with such a deliberate and absent-minded participation.

From this point of view, cell phone jammer for meetings are not necessary, but necessary. Compared with the small probability event of cutting off the network cable and “delaying work”, the negative effects of playing mobile phones are much greater. We often talk about holding useful and efficient meetings. The “useful” and “efficient” here mean that the content of the meeting must be free from formalism and less idioms in Mandarin. At the same time, it should also include the attendees, heart, and brain. If all of you here are “people sitting in the meeting place and their hearts floating on the Internet”, the meeting will be reduced to another form of formalism. If we are opposed to meetings for the sake of meetings and emphasize on solving practical problems, then we should also be wary of perfunctory participation attitudes, and we should also restrict mobile phones from “buzzing” and “didi” disturbing people’s minds. “If you have a problem, hold a meeting and put it on the table to discuss.” “Large meetings, medium meetings, and small meetings are all necessary.

Explain the function of GPS jammer

When purchasing and using vehicle mortgages, it is best to configure GPS jammer within a certain stage. Especially some car dealers who hand over the car and purchase the mortgaged car, in other words, once they receive the car, they can turn on the GPS jammer and put one in the car, and one in the car trunk! When the shield is turned on, you can be assured of peace of mind when you take the car back and forth. However, the jammer cannot be activated 24 hours a day, so after the safety reaches its own chassis, you must find a technical professional to investigate the GPS by yourself, and modify the GPS positioning equipment and mortise locks, key changes and other security guards to prevent mistakes. just in case.

gps signal blockers

1. Understand the GPS jammer
GPS jammers (jammers) can reasonably prevent being tracked by GPS communication satellites, reasonably affect GPS communication satellite signals, and maintain your track privacy protection and information business secrets.

2. The function of GPS jammer
The GPS signal is the same as the signal on the mobile phone, it is very susceptible to the influence of electronic components. The signal jammer can shield all the signals in a certain range, so that all communication devices in the range lose the signal. The installation of a GPS locator on the car enables buyers to easily find their own car on the GPS monitoring management platform. As everyone knows, such a good product is also found by criminals to find loopholes. If you buy a signal blocker on Taobao, Turn on when the car is stolen, there will be no signal in the car, and the car will go offline on the service platform, as if the whereabouts of the car are unknown, you can’t find it anyway.

3. Disadvantages of GPS locator
I have to admit that the GPS jammer also has disadvantages for the user. The signal jammer is only temporarily turned on, and it is unlikely to be turned on all the time. If he turns off the jammer, the GPS locator will have a signal again. Drivers can quickly find the stolen car based on precise positioning information.

In addition to signal jammer, some people will say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also an objective fact, but this is only valid for some GPS devices. If the GPS tracker is in a dormant state most of the time, the signal detector will not be able to detect it! what happened?

For example, some ultra-long standby GPS locators can only be awakened once a day. After being awakened, the precise positioning information of the vehicle is sent back to the buyer’s network platform and then it enters the dormant state. In the dormant state, it is Without a signal, it is absolutely impossible for car thieves to detect it! In addition, it is also free of wireless network installation. There is no wiring on the surface of the machine and equipment. It can be placed anywhere on the car (if it does not have to be placed in an area blocked by the signal). It is very concealed for engineering safety.

To prevent students from playing with mobile phones

Nowadays, more and more students have smart phones. In order to prevent students from playing mobile phones at school to affect their studies, especially the phenomenon of playing mobile phones after going to bed at night and turning off the lights, Xin’anjiang Middle School recently installed several mobile phone signal jammer. This move caused objections from some students.

Student: I’m not used to the cell phone signal

On November 8, a netizen broke the news on Baidu Tieba of Xin’anjiang Middle School, saying that “I heard that mobile phone shielding devices are harmful to the body.” In the following days, there were several more posts about the school blocker, which triggered discussions among many netizens. Another netizen made up a poem: “I saw high-voltage lines during the day, high-tension lines at night, and high-tension lines every day…”, and nearly 30 comments were posted.

gps wifi cell phone jammers

On November 12, the reporter came to a certain class of the third year of the school and asked 4 boys, 3 of whom used smart phones and 1 used ordinary mobile phones. A boy told reporters that about half of the classmates in the class brought mobile phones, mainly for making calls. Nowadays, mobile phones have many functions. They also use mobile phones to watch TV shows, read news, read novels, and chat with friends. He complained to reporters: “The mobile phone has no signal and life is less interesting. I am really not used to it.”

In another class, the reporter learned that in addition to contacting family members when using mobile phones at school, girls also use their phones to shop on Taobao, check Weibo, and play WeChat. Some girls also use their smartphones to play with foreign social software such as Twitter, Facebook, and Instagram.

School: Schools should be responsible for the management of students, and mobile phones should be used reasonably at school

Principal Lai Zhonglin of Xin’anjiang Middle School said frankly that it is very common for students to bring mobile phones. Most of the mobile phones used by students are smart phones. They can play games, watch movies, go shopping, make friends and chat… The school clearly requires students to use mobile phones reasonably and is strictly prohibited in teaching. However, some students have poor self-control ability, especially after going to bed at night and turning off the lights, there are still students playing with mobile phones until late at night, which seriously affects the next day’s study, so that they start to doze off early the next day and lack sleep for a long time It will also affect your health.

In order to prevent students from using mobile phones at school to affect their studies, especially the phenomenon of using mobile phones after going to bed at night and turning off the lights, Xin’anjiang Middle School installed several mobile phone shielding devices. Lai Zhonglin said that the jamming device is mainly near the bedroom, and the activation time is a certain period of time, not all day, and the use time during the exam is slightly longer than usual. The shielding devices installed in the school are in compliance with the standards for the use of the college entrance examination and have safety guarantees. At the same time, the school also visited surrounding residents and units and asked the mobile company. The results showed that the shielding device did not affect the normal life of the surrounding area.

In response to the students’ messages in Tieba, School Lai also replied: Student mobile phone management is a problem that every school will encounter. The school hopes to get the attention and attention of relevant social departments and provide technical guidance. As a school, it should assume the responsibility of managing students. Students are asked to concentrate on their studies in school. Parents are also expected to understand, cooperate and support the school’s mobile phone management. Moreover, the school has a school messaging system that can meet the needs of students and parents. Contact demand.

Surrounding residents: no impact on normal life

On November 12, the reporter randomly interviewed several residents near Xin’anjiang Middle School. An employee of a company near the back door of the school said that the installation of the shielding device in the school did not affect the company’s employees’ mobile phone use and normal life. Mr. Wang, the owner of another small shop, also said that his mobile phone signal was not affected.
