In recent years, the UAV industry has achieved vigorous development in both the military and civilian fields. In the civilian field, drones have played an important role in agriculture, forestry and plant protection, emergency rescue and disaster relief, logistics and transportation, and safety inspections. Intelligence gathering, electronic reconnaissance, etc. have played a great role.
At the same time, with the increasing popularity of various remote-controlled helicopters and easy-to-operate aircraft, accidents such as interference with aviation orders occur frequently to varying degrees, posing severe challenges to the security management of important areas.So drone jammer is essential.
Although some drone companies have designated a no-fly zone for drone flight in their products, the threshold for online trading of drone accessories is very low, and it is easy to assemble a drone that can fly. Additionally, most drone users fly their drones in various no-fly zones without basic flight and safety training. Affecting civil aviation safety, bombing planes, wounding people and other incidents have occurred from time to time.
UAV anti-jamming is the safety prevention and control of UAVs, which has become the focus of the UAV industry. UAV confrontation has become very important, not only to monitor remote UAVs but also to avoid various security risks.

How effective are drone jammers?
Now that the drone market is gradually liberalized, the development prospects of the drone interference countermeasure industry are full of huge potential. Data shows that in recent years, the sales of drone jammer has grown rapidly, and the application places of UAV confrontation have gradually increased. The future of the drone-fighting industry is sustainable.
At present, UAV jammers mainly use radio detection and jamming signal technology to track, monitor and jam UAVs. The radar function mainly detects drones in radio conditions, at great distances. That is, UAVs using this technology consume a lot of power, and there may be blind spots in some areas, making it difficult to achieve ideal confrontation. Countermeasures against drones. In addition, using infrared technology, since it can take photos for evidence collection, it can also implement anti-drone measures, but it is greatly affected by the environment and visibility, and the distance of the drone cannot be measured. Using radio information technology, drones can be detected at a higher level, but with higher environmental requirements.
The above-mentioned drone signal jammer technologies have their own advantages in realizing functions. Although there are still some deficiencies in drone jammer device, it is conceivable that with the continuous development of future technology, it will further integrate the functions of UAV activities. According to regional characteristics and environmental factors, carry out comprehensive UAV defense and confrontation to ensure air defense effectiveness.

Is it possible to destroy drones using drone jammer equipment?
GPS signals are the main way to control drones. Generally speaking, in the process of signal propagation, there is a certain distance between the remote control and the drone, and the signal is relatively weak at this time. Therefore, it is easier to use drone jammer against drones at this time, and it is also easier to jam GPS signals. Most consumer drones choose GPS signals for flight control, and these GPS signals are not encrypted, and drone jammers seize this vulnerability to take action. Currently, drones can land or return by sending strong jamming signals and suppressing control signals. on this principle. The device can send a full-frequency jamming signal to the drone after the drone is powered on, so that it can land automatically without operator control without receiving any control signals, ensuring the safety of the protected area.
Now, some secret areas have "no-fly zones". Many drone manufacturers have built-in components with "no-fly zones" that prevent drones from flying in certain areas. Even flying into the "no-fly zone" from elsewhere can cause the drone to land itself. To this end, as long as the drone signal jammer simulates the GPS ground signal and determines the geographic location, the drone can make a forced landing. At present, domestic UAV jamming technology is still in the development stage. Due to the continuous updating of drone technology by drone manufacturers, the current technology mainly uses signal shielding for drone interference.

Is it possible to destroy drones using drone jammer equipment?
DJI's DJI Mavic 3 (Yu 3) drone has been on the market for a while now. Recently, a customer reported a problem when communicating with us: the previously purchased and installed drone jammer was not suitable for this new type of large drone. Xinjiang's DJI Yu-3 (Yu-3) UAV does not seem to have a significant interference effect, especially when it comes to expulsion and forced landing. Compared with the performance of other drone models after interference, there is still a certain gap. The client wants to know why this is happening and what is a good solution.
First of all, you need to know that every time DJI launches a new drone, its anti-jamming capability will be further optimized and upgraded. According to our detailed analysis, DJI's new DJI Yu 3 (Yu 3) UAV, its remote control flight control and image transmission, uses the most commonly used 2.4G and 5.8G frequency bands but jumps in frequency anti-interference ability have been better enhanced. Compared with the previous model, the more special change is the addition of the Beidou positioning module to its navigation and positioning module. Knowing this, it is possible to roughly analyze the reasons for the weakening of the UAV jammer in terms of driving away and forced landing.
The drone UAV jammers produced and supplied in the past have built-in GPS navigation and positioning jamming modules, and the frequency coverage may not have enough frequency bandwidth reserved, resulting in jamming signals that cannot fully act on the Beidou navigation frequency. From the perspective of frequency division standards, the frequency range of Beidou Navigation has exactly two frequency bands, which are located in the start and end areas of the GPS1.5G frequency band. The solution to this problem is not difficult or complicated. Our suggestion is to return the original drone jammer to the factory to re-tune the transmit frequency in the GPS band.
In the face of the continuous introduction of various new drones, it is impossible for drone signal jammers to remain conservative all the time. They should also keep pace with the times and update progress at any time!

What methods do drone jammer rely on to combat drones?
Reasonable drone jamming countermeasures in the face of "black flying"
Currently, there are a variety of means and methods to counter drones, and a wide range of drone jamming or countermeasures are emerging. Recently, drone detection + drone jamming solutions have also been emerging. In the course of discussing many drone defense solutions, some customers have asked whether it is feasible to directly destroy drones using drone strike equipment. In other words: in the defense zone, once an illegal intruding drone is detected, it is immediately shot down or even destroyed by a drone strike device. Is this solution fully realized?
The drone strike equipment mentioned here does not refer to the drone jammer equipment often mentioned in the past, but specifically to the strike weapons or attack methods that have hardware damage to drones, such as the use of bullets, shells, etc., and laser irradiation. And so on. This will permanently damage and destroy the drone.
If UAV strike equipment is to be used for precision strikes against incoming drones, it must ensure that the drones can be identified within effective defense range and that the direction and coordinates of the drone attack can be identified. Precise judgment and path locking further guide the UAV strike equipment to conduct precise attacks on them to achieve a one-hit kill effect.
In terms of the current state of the art, there are already a variety of means available for UAV detection, such as radar detection, wireless spectrum analysis detection, optical capture, etc. These are then linked with UAV striking equipment so that the above-mentioned UAV destruction can be achieved.
It is just that the above-mentioned solutions have high hardware investment costs in implementation and require a high level of operator skill in field real-world applications. Jammer mart as a manufacturer of drone signal jammer, our advice is that there is generally no need to raise the technical standard of UAV defense to such a high level unless there are important places with special needs, which seems like overkill.
We made the analogy that drones are like mosquitoes, and drone jammer devices are like mosquito coils. In terms of self-protection, putting a mosquito coil is enough to keep the mosquitoes away and out of harm's way. Mosquito incense can also kill or drive away mosquitoes. But to be serious, you have to take guns, cannons, etc. to put out the mosquitoes one by one.

The drone jammer countermeasure device consists of a shielding host, low-frequency/high-frequency antenna, and power supply. When the drone jammer device is turned on, it can transmit signals that interfere with the 1.5GHz/2.4GHz/5.8GHz band of the drone. By shielding the UAV's flight control signal and satellite positioning signal, the UAV cannot continue to fly after receiving the flight control signal and satellite positioning. Depending on the drone model, there will be different control effects such as return to flight and landing.
Usually under the use of UAV jamming countermeasures, when the no-fly defense zone encounters a "black" UAV, the operator and the no-fly zone will have this distance. The drone takes off from the controller and flies gradually closer to the no-fly zone. In the process, the distance between the drone and the controller will get farther and farther away. Instead, the drone approaches the no-fly zone more closely. In summary, all signals sent by the operator to the drone gradually diminish due to the distance. Conversely, the closer the drone uav jammer countermeasure is to the target, the stronger the signal from the UAV jamming, provided that the power is equal. At this point, the controller accepts the signal sent by the UAV is weak, and the UAV jamming countermeasure device uses multiple frequencies to send high-powered jamming signals to the target UAV to suppress the UAV's control signals. At this point, the signal of the "black flying" drone is easily interfered with, and the drone can only land or return.

In recent years, the drone industry has developed rapidly, and drones have gradually entered the public eye. When some ordinary people come into contact with drones, they have not received professional training to control drones, which has also caused a large number of drones to "fly black". For example, once an airport is continuously disrupted by drone activities in just one week, resulting in large-scale flight delays, return flights or temporary landing at other airports, causing serious losses to airlines and seriously affecting social and public order and safety. Drones The use of drone jammer can effectively limit the "black fly" situation.
The drone signal jammer transmits high-power interference radio frequency signals by means of signal interference blocking, which interferes with the signal connection between the target drone and the operator, so that the drone cannot continue to be controlled, thereby triggering the drone's return to home and landing function. The UAV jammer can continuously transmit electromagnetic wave signals of directional signal frequency to the UAV within the effective range, cutting off the signal transmission between the target UAV and the ground remote controller. This jamming method does not target a single frequency signal, but all signals used by the drone. Therefore, drone jammers can work as long as they are in the frequency band used by drones.

At present, drones have become mechanical devices often seen in people's lives and are widely used in various fields. It can even be used in some unique places, such as tourism, emergency rescue, and sailboat shooting. In recent years, online short videos have emerged. In order to obtain illegitimate benefits, some people use drones to illegally shoot some private places, and then make videos for distribution, making huge profits. So many regions will choose to limit this with drone jammer, which also play a big role.
In some areas, the safety hazards brought by drones will appear at any time, and there is no fixed time. The technology sets up a "no-fly zone" on the site, which is a sizable protective barrier. In the "no-fly zone", send a wireless signal to the "Blackfly" drone to make an emergency landing. Not only can it save a lot of manpower input, but it can also guarantee the safety of the performers to a large extent. For other organizations or classified units, the drone signal jammer equipment makes the accident UAV return to flight or on the way, and cannot continue to use equipment such as cameras.
Since the UAV must use wireless signal transmission, it can achieve the effect of signal confrontation against the UAV, making the UAV out of control and unable to drive further into the protected area, so as to achieve the purpose of countering the UAV.

In recent years, as drones have gradually entered our daily life, they have performed prominently in environmental monitoring, express logistics, power inspection, disaster rescue, and aerial photography. Although the drone industry has developed rapidly in the past two years and drone technology is very mature, there is still a problem worth thinking about, that is, how to prevent the occurrence of security incidents caused by drones. This requires professional drone jammer countermeasures to monitor and jam drones. So what method does this countermeasure device rely on to restrain the drone?
In some places, by developing application software, using positioning data to intervene drones, and by locating "no-fly zones" in real time, they provide drone users with flight prevention to avoid accidental entry. Now, the management regulations for drones are gradually improving, especially the anti-drone jammer technology is gradually mature. Strive for as many drone flight rights as possible to promote the healthy development of the drone industry.
Under the condition of ensuring the safety of low-altitude areas, some areas use drones to interfere with drone signal jammer equipment to reduce the occurrence of "black flying" as much as possible. The drone frequency jammer device interferes with the application function on the UAV, making the control system on the UAV ineffective, and the operator cannot control it, which indirectly causes the UAV to stop flying.
