Drone Jammers as an Important Part of an Anti-Drone Defense System
Technological advancements have had a positive effect on all parts of life. However, this has also brought in a few challenges. The biggest challenge that has become tough for the authority to tackle is regarding the national defense. Technological advancements like drones are known to be beneficial for commercial or recreational use. However, when used near a country’s defense by the enemy, it can easily become a harmful weapon. Drones can potentially expose a country’s defense to the enemy, which is why it becomes important to look for a shield against them.
Well, a drone jammer is one such thing that works as an important part of an anti-drone defense system. This blocks the functions of a drone and stops it from doing what it’s capable of. In here, we will focus on how drone jammers work as an important part of the anti-drone defense system. We will highlight its features, functions, and the benefits that it offers.
The Need for Anti-Drone Defense
In recent times, there has been a growing number of drone-related incidents in restricted areas. From airports to military bases and even private estates, drones are being used to harm people and sometimes even end their lives. As of recently, a Russian drone strike on Ukraine took the lives of 9 people, and more than 60 were left injured. Moreover, this is not a stand-alone incident, and there have been many of the same kind in recent times. So, it is quite easy to understand that if not handled effectively, drone attacks will only increase and cause more fatalities than any other type of weapon.
This is why creating a good anti-drone defense system has become important. A well-designed system of this sort stops the drone from doing what it was sent for. This system involves high-end technology like drone jammers, which interfere in the way of the functionality of the drone. Thus, it works like an effective solution for protecting sensitive airspace. Ultimately, helping to save the lives of those who stand at the forefront of these attacks.
What Are Drone Jammers?
Drone jammers are one of the most important parts of anti-drone devices. This technology works by using electromagnetic noise, which focuses on the radio frequency of a drone. This alone poses a big issue in the drone’s mechanism as drones need radio frequency to emit information and even operate properly.
Jammers target radio frequencies of 2.4 GHz or 5.8 GHz, or GPS of 1.5 GHz. This way, the drone loses its capability to connect with the operator or GPS signal, ultimately losing its function. These jammers can be of a few different types. They can be handheld jammers, stationary jammers, or mobile systems. The most effective one out of these is by far the stationery one. It is kept in one place, and it keeps close watch on any drone that can come within its proximity. The device is capable of operating on its own and doesn’t need any additional assistance.
Features of Drone Jammers That Make All the Difference
Drone jammers come with highly advanced features that make them an important part of an anti-drone defense system. Some of the features of this technology that make it an important part of maintaining security are:
Efficient jamming
Most drone jammers come with 300 MHz- 6 GHz full-band jamming capacity, that too without any type of violence. Other than that, some drone jammers also come with the capability of jamming multiple frequencies like 410- 440MHz, 840- 930MHz, L1 GPS 1.57GHz, L2 GPS 1.22GHz, and others.
Easy to install
Anti-drone jammers can be easily installed with the help of any fixed pole. These are extremely lightweight and compact, which makes them easy to install and to use. This is exactly what makes it suitable for deploying them on a long-term basis for regional protection. The drone jammer can be easily erected with the use of the tripods that come with it. This is also how these jammers become appropriate for events that require large-scale security or for those that fall under low-altitude protection tasks.
Smart design
From its digital system to its structure, everything is designed keeping efficiency in mind. This anti-drone device system comes with many modulation forms like BPS, QPSK, FSK, and others. Other than that, the entire device has modules like jammers, a mounting bracket, and high-speed PTZ, all of which work in making the system more compact. Most important of all, some anti-drone jammers come with amplifiers that follow gallium nitride broadband process, each segment of which has even more power than 100W.
How Drone Jammers Fit Into a Larger Anti-Drone System
Drone jammers are always an important part of an anti-drone system. This follows a “soft kill” method for functioning, which makes it capable of disabling or disrupting drone operations. As discussed before, this technology works by jamming or interfering with the drone’s communication signals, GPS, and other navigation systems.
So, naturally, it prevents it from receiving instructions or maintaining its flight path. This, in the end, leads to the drone returning to its home point, landing in place, or losing control completely. As a result, the drone potentially crashes and gets damaged completely.
The jammers work in different phases in an anti-drone defense system, the first one being detection. During this radar, RF scanners, acoustic sensors, and visual tracking are used to detect incoming drones. Next, the tracking phase begins, where the drone’s model, origin point, and flight path are identified properly to fight against it. The last phase is the response phase, where the jammers show their proper functions. They are deployed once a drone is confirmed as a threat, and then proceed to control its operations.
Most of the jammers use techniques like RF jamming that block communication between the drone and the controller. Other than that, they also use GNSS (GPS) jamming that disrupts the drone’s navigation system. However, the best technique of all is Protocol Manipulation, which spoofs or hijacks control of the drone, making up the biggest reason why it is used in government or military-based systems. This, as a whole, is a simple way that drone jammers seamlessly fit into a large anti-drone system.
Conclusion
The importance of drone jammers in anti-drone defense systems in modern airspace security is undeniable. These are an essential component, especially when paired with proper detection systems. Through this blog, we worked on highlighting the importance of this technology and the useful features that come with it. In the end, it is important to note that as drone usage increases, so will the need for smarter, more scalable countermeasures for drone defense.
