Drone technology has drastically evolved over the years. There has been a rise of model, autonomous, and remotely controlled types. Such drones have improved tasks such as security surveillance, insecticide spraying, photography, rescue missions, package delivery, and environmental monitoring. However, the use of drones and Unmanned Aerial Vehicles (UAV) by criminal groups and terrorist organisations is on the rise.
Governments and large organisations are now facing the need for anti-drone countermeasures. Between 2018 and 2024, there have been 810 drone-led invasions by non-state groups. It is estimated that the incidents resulted in 1500 injuries and 1300 deaths. Today, the safety of public spaces from drones can be ensured using anti-drone jamming systems, tracking, and detecting systems.
Types of Anti-drone Systems
1. Drone Radar Detector/ Radio Frequency (RF) Detector
Drone radar or RF detectors are systems that are designed for detecting drones. However, these systems are not capable of jamming or neutralising drones. The ND-BR002 Anti-Drone RF Detector is an example of such a system. The ND-BR016 is a full-band version of the system, which means that it can cover all the ranges of frequencies that drones use for stashpatrick wireless communication. Similarly, the ND-BR019 is a handheld version of the system.
2. Drone Jamming System
Drone jammers are systems built only for jamming drones. These systems are not designed for detection or tracking. However, you must remember that drone jammers can be directional or omnidirectional. While directional antennas can only send and receive signals in one direction. The omnidirectional antennas are capable of transmission and reception of electromagnetic was in every direction along a plane.
The ND-BD002 is a directional anti-drone jamming system, whereas the ND-BO004 is omnidirectional. The ND-BD008 is a directional jamming system but comes with the full band. The choice between directional and omnidirectional anti-drone countermeasures will depend on your specific security scenario and detection needs.
3. GPS Spoofing Jammer
Jamming and spoofing are two approaches used by adversaries to cause disruption to navigation, time, and position signals available from GPS. Although spoofing and jamming are almost the same types of anti-drone countermeasures, there are differences between the two.
Spoofing is about making a GPS signal receiver calculate position wrongly. Similarly, jamming involves locally overpowering GPS connections using other RF signals. The goal of this is to stop the GPS receiver device of the drone from operating.
Spoofing jammers essentially send out a “spoofed” or imitated version of GPS signals to the drone’s positioning device. As the target GPS module fails to distinguish spoofed from real signals, the drone calculates its position wrong and appears to be elsewhere. The ND-BG002 is an example of such a spoofing jammer.

4. Drone Tracking System/ Camera
Drone trackers are systems that are meant for tracking drones. Such systems are made by integrating cameras with detection tools to track drones. These systems are packed with both visible light and thermal imaging cameras that ensure that drones can be tracked continuously in all weather conditions. The ND-BC011 is an example of a drone-tracking camera system.
Stationery Uav Control Systems
1. Standard Anti-drone System
These are standard systems that can be monitored as well as controlled using command centre software. These systems are typically capable of tracking drone recordings, detecting in long range, and causing interference to signals. The ND-BU001 is an example of such a system, which combines an active radar, a directional jammer, and a dual camera.
2. Passive and Advanced Passive Anti-drone Systems
Passive systems are built with a directional jammer, an RF detector, and an adequate direction range. These are basic versions of anti-drone products that come at a lower price. The ND-BU003 is an example of a passive system. The ND-BU005 is an upgraded version of the passive system that is optimised for anti-drone measures in low-altitude airspace. The advanced version also has a full-band detector and jammer.
3. Base Security Anti-drone Systems
Base security systems are designed for accurate monitoring and surveillance in low-altitude areas, continuously. The systems come with full-band jamming and detecting units. These are also powered by advanced space-time processing technology. The ND-BU004 is an example of such a base security system against unwanted drones.
4. High-end Anti-drone System
These systems are generally deployed as a part of advanced anti-drone countermeasures. High-end anti-drone systems are powered by novel technologies such as 3D Pulse Doppler radar and have a significantly extended detection range. Hence, these systems are widely used for the protection of critical areas. The ND-BU002 is an example of such a high-end system.
Handheld Uav Control Systems
1. Handheld Anti-drone Systems and Jammers
These devices are small in size, lightweight, and mobile. Such devices are generally used for protecting the lower altitude during large events, important meetings, and area patrol tasks. These systems are capable of detecting as well as jamming drones. The ND-BD003 and the ND-BD004 are examples of such systems.
2. High-end Handheld Systems
These are handheld anti-drone systems with the same lightness, compactness, and portability. However, these systems offer stronger and more advanced low-altitude security. These systems can also be deployed alongside other anti-drone countermeasures. The ND-BD005 is an example of such a system.
Final Thought
Governments and large businesses have a number of anti-drone countermeasures and technologies to choose from. The best solution for them depends on their security needs and budget. You can choose to have handheld systems for less critical area protection. You may also deploy advanced stationery systems for complete omnidirectional security coverage.
