How is Drone Defence Used?

Protect your airspace

Drone defence is an important asset for critical infrastructure, airports, prisons, maritime and stadia, as well as for organisers of major events.


There have been numerous incidents of drones causing disruption at airports. Think Gatwick in December 2018. Drone defence protects this sensitive airspace from UAS intrusions and reduces the risk of drones colliding with manned aviation.


Drone defence can be crucial for maritime operations to protect valuable cargo, crew and passengers. Vessels are particularly vulnerable when they have limited manoeuvrability, such as when they are docked in port or passing through narrow straits or canals. Drone threats include aerial reconnaissance, breach of privacy or being deployed as a missile.


A high-profile sporting event or open-air festival are attractive targets for malicious drone operators. Unmanned aircraft can be used to capture unauthorised footage, interrupt the game, and cause damage. They also present serious hazards for players and spectators.


The 2019 attack on oil-processing facilities in Saudi Arabia showed the carnage of a drone strike on critical infrastructure - causing huge damage and having a significant impact on global financial markets. Drones can also be deployed by activists who can fly around nuclear sites, oil installations, fracking sites and other critical infrastructure to cause damage, disruption and/or publicity.


In highly-sensitive and politically-important area, drones can be used for terrorism and for spying. Ladden with bombs or other hostile payloads, drones can attack property and cause threats to life. They can also be deployed for reconnaissance missions, collecting sensitive and private information to prepare for an attack and obtain intelligence.


Drones have become a useful and fairly anonymous tool for criminals to drop illicit substances or other contraband into prison grounds. Bring drone defence into action around the prison’s parameter to counter this illegal activity. Some systems also enable you to track the location of the pilot.

Don't Cry Wolf:
No False Positives

Data integrity is crucial. Inaccurate information can hinder the creation of effective standard operating procedures and emergency response plans.

Reacting to a false alarm can also be expensive and labour intensive.

Then there’s the classic Cry Wolf™ scenario: Ignoring warnings due to the past experience of false alarms - only to suffer a drone attack when resources have not been deployed.

That’s why drone defence is key. Tools such as heat maps, real-time telemetry information and Remote ID provide a robust and trustworthy solution to reliably raise the alarm and counter a drone threat.

A catalogue of historical reports can then be compiled to use analytical learning to plan for and tackle/prevent future threats.

A layered solution is most effective for data integrity, utilising different sensors with different capabilities to identify a broader range of drones and cross-reference detection data and risk levels.

Radio Frequency Drone Detection

These passive systems scan the airspace for drone frequency bands, detecting a communication link between the drone and controller/pilot. Access information about the drone.

Layer 1 features a single RF detection device, such as DJI AeroScope or Dedrone.

Additional RF sensors to detect a wider array of drones, including non-DJI.

A dual solution, integrating technology such as AeroScope and Dedrone, to detect a wider range of drones and cross-reference alert data.

Add radar to the dual RF solution

Radar identifies a drone in the airspace by picking up emitted radar signatures from the aircraft. It can measure the drone's direction and distance.

Other solutions can be added at this stage, such as cameras to capture drone movement, either using appearance-based, motion-based or hybrid methods.

Mitigation Strategies & Equipment

Multiple mitigation equipment can be implemented at this stage, but is unique to each use case and country of operation.

As such, scaling a C-UAS programme with the appropriate Layer 4 drone defence mechanisms requires detailed analysis and consideration.

heliguy™ drone defence specialists will work with you to provide bespoke and tailored solutions.

Layered Drone Defence

Multi-tiered Solution For A Comprehensive Drone Defence Strategy

A layered solution is the most comprehensive form of drone defence, with multiple technologies working together to plug the gaps and provide a more robust and complete defence strategy.

These systems are integrated via a middle-layer software with full automation and remote monitoring/alerts.

Drone defence is scalable, adding extra sensors and mitigation strategies in a phased and modular approach.

What kind of drone data is detected?

A Tier 1 RF sensor solution alerts personnel to a drone attack and collects crucial information such as the drone name, speed, and altitude, as well as the location of the drone and pilot.

Additional detection technology, added at the Tier 2 and 3 stage, provides extra information about the drone.

These data-driven insights can then be used to engage mitigation strategies as part of Tier 4.

    Dedrone RF-360 Sensor

    The Dedrone RF-360 can be used as a passive RF companion to DJI AeroScope.

    It is a network-attached drone defence RF system, purpose-built for the detection, classification (i.e. identify the manufacturer and/or model), and localisation (geolocation) of drones.

    With a coverage range of just over 3 miles in ideal conditions, it receives and analyses radio signals from drones in the airspace.

    Working in conjunction with the DroneTracker Software, Dedrone RF-360 detects almost all commercial, hobby and home-made drones. This helps to determine threat levels of nearby drones to enable quick and data-driven decision-making.

    PTZ Cameras

    Deploy a Pan, Tilt, Zoom (PTZ) camera to visually identify a drone and its payload to gain highly-valuable situational awareness.

    Equipped with Pan, Tilt, and Zoom functions, the camera can monitor a large section of the airspace and can detect small drones from a great distance.

    Use high-resolution imaging to verify and track an approaching drone to gauge threat levels and collect visual evidence for any potential prosecution.

    Drone Radar

    Radar is an effective drone defence solution, using radio energy to detect an object.

    Drone detection radar sends out a signal and receives the reflection, measuring the aircraft’s direction and distance (position).

    Benefits of drone radar include its long range, ability to constantly track an object and to provide highly accurate location data. It can handle hundreds of targets simultaneously and is not impacted by visual conditions, ie night, fog etc.

    Radar can be particularly effective when used in conjunction with a PTZ/visual camera.

    CPNI Approved Solutions

    DJI AeroScope and Dedrone technology have been endorsed and certified by the UK's Centre for the Protection of National Infrastructure (CPNI).

    The CPNI counter-drone standard enables organisations deemed to be of critical national importance, including refineries, data centres, airports, and ports, to adopt drone detection technology with the assurance that it has been tested rigorously.

    The standard evaluates mature and readily-available solutions, helping practitioners identify appropriate physical security equipment.

    DJI Aeroscope

    DJI AeroScope was assessed successfully under the CPNI Counter Unmanned Aerial Systems (CUAS) Detect, Track and Identify (DTI) Testing and Evaluation Standard.

    During the CPNI assessment, AeroScope was found to be very simple to set up, learn and use with an intuitive interface. It responded to multiple UAS (Unmanned Aircraft System) operating concurrently and the detection, tracking and identification performance was consistent.


    Dedrone was awarded certification from the CPNI for its counter-drone technology platform, DedroneTracker.

    DedroneTracker detects, identifies, and locates drones by using multi-sensor capability combining radio frequency, radar, and optical sensors.

    As part of the CPNI assessment, Dedrone technology was evaluated to detect drones within a specific launch time and provide consistent and reliable tracking, timely alerts, and notifications, with DedroneTracker software showing reliable information on drone heights, speeds, and ranges.
