Drone Defence


what does drone defence mean?

Simply put - you're protecting your airspace against drones that may enter it without your permission.

Why do you need drone defence?

Drone defence has become an important asset for critical infrastructure, airports, prisons, and stadia, as well as for organisers of major events

There’s no doubt that drones are great machines; providing hobbyists with hours of fun and helping commercial pilots save time, enhance safety, capture fast and accurate data, and increase efficiency and ROI.

However, if put into the wrong hands, UAS (unmanned aerial system) can be used for illegal or illicit means, whether that be as a smuggling device, a tool for terrorists or to simply cause nuisance.

This is why installing counter-drone technology and having a drone defence strategy is essential.

The incident at Gatwick Airport in December 2018 showed the disruption that can be caused by alleged drone sightings, which resulted in the closure of the runway for 33 hours and cost a total of £50m to the airport, airlines and insurers.

Heliguy - Drone Defence In Numbers

DJI AEROSCOPE - DJI's Drone Detection Solution

An Essential Tool For Drone Defence.

What Is AeroScope?

DJI AeroScope is a purpose-built drone detection system, allowing an operator to quickly and easily track real-time telemetry data from DJI aircraft.

This allows the operator to protect their airspace and make an informed decision amid a drone threat.

DJI AeroScope comes in mobile and stationary formats and the most powerful system can identify drones within a 50km range.

Why Choose AeroScope?

Heliguy Detect is built around DJI AeroScope.

Since the beginning of 2019, Heliguy-supplied AeroScope systems have picked up more than 340,000 drone flights - with some of these operations exceeding the legal restrictions. Having this data gives users a clear picture of how drones are operating within their airspace and gives them the chance to act quickly and decisively to combat a potential threat.

DJI drones are world-leading because they are easy-to-use out-of-the-box solutions which provide reliable results. DJI AeroScope is no different.

The system is a quickly-deployable solution which captures data rapidly and in a digestible format.


DJI AeroScope Passes Rigorous Security Testing 

DJI AeroScope has been proven to be a secure system, after being evaluated and subsequently passed by the UK’s Centre for the Protection of National Infrastructure (CPNI).

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

As a result, DJI AeroScope will be included in the CPNI Catalogue of Security Equipment (CSE). The CSE is available to help security practitioners identify appropriate physical security equipment.

CPNI’s assessment found the following:

  • AeroScope is very simple to set up, learn, and use;
  • The system has an intuitive interface;
  • AeroScope responded to multiple UAS operating concurrently;
  • The detection, tracking and identification performance was consistent.

How Does DJI AeroScope Work?

DJI AeroScope – which acts as an electronic license plate – is a passive advanced-warning system which can remotely identify airborne drones. By using AeroScope, law enforcement, aviation and other authorised agencies can manage their airspace, keep track of a drone's whereabouts and take action against a rogue UAV threat.

AeroScope's underlying technology and advantage is that it uses the existing communications link between the drone and its remote controller to quickly collect information about the drone, such as:

  • Drone Serial Number
  • Make and Model
  • Precise Drone Location
  • Drone Speed
  • Drone Direction
  • Home Position
  • Pilot Position (if pilot is using a GPS enabled device)

Authorised users such as airports and police departments can see this information displayed on a computer map for every drone within the multi-mile range of AeroScope’s antennae.

This telemetry information is broadcast directly from the drone to the AeroScope receiver, allowing authorities to identify and track those drones, and take action if any of them raise concerns.

AeroScope is a Remote ID system which detects DJI’s five radio types. These are:

  • Lightbridge
  • Lightbridge 2
  • OcuSync
  • OcuSync 2
  • Wi-Fi

Due to the rich information that is collected by AeroScope, if legal proceedings were to commence after an illegal flight, AeroScope can generate a detailed log of every flight detected by the system, which can be exported and saved to be part of the investigative file and report.

AeroScope comes in a number of different forms - either portable or the permanent G8 or G16 systems.

As an added advantage, DJI AeroScope strikes a reasonable balance between the authorities’ need to identify drones that raise concerns and drone pilots’ right to fly without pervasive surveillance.

DJI AeroScope Configuration Options

AeroScope Portable

The portable unit can detect drones within a 5km radius.

It is ideal for short-term, temporary deployment.

The easy-to-deploy system is self-contained in an IP-54 rated hard case, operating Android OS on a CrystalSky controller.

The portable unit operates on either mains power, or intelligent, hot-swappable batteries.

External antennas can be optionally deployed.

The portability and convenience of the mobile unit makes it ideal for tactical situations where stationary units are unavailable.

AeroScope "G8"

The G8 system can detect drones within a 30km radius.

It offers the widest variety of deployment options.

The G8 incorporates a four-panel array of high gain directional antennas which detects across the 2.4 and 5.8 GHz frequency range and provides 360-degree coverage.

The system includes a weather resistant radio system that can endure harsh conditions.

The system is equally applicable for both permanent installations and temporary ones.

It can be installed on buildings, towers, or mounted on mobile command posts.

AeroScope "G16" Fixed Installation

The G16 system can detect drones within a 50km radius.

It offers the most expansive coverage thanks to its large antenna array and multiple radio units.

AeroScope's G16 configuration incorporates separate 2.4 and 5.8 GHz antenna elements. For 360-degree coverage, the G16 includes a 32 element antenna array and four radio units.

The G16 is suited to be installed on a building or tower for long-term use.

This system is ideal for permanent installations for clients seeking extended coverage areas and early warning, including airports, sea ports, military and nuclear facilities, prisons, and stadiums.

Real-time Drone Monitoring

DJI AeroScope allows you to view a summary of a drone flight in real-time, showing the flight position of the aircraft, its height, speed, and pilot location.

This gives you precise, actionable data, which can be used to make an informed decision about protection your airspace.

Statistical Reporting

The Statistical Report page shows an overview and an analysis of the detection data. This provides information about the number of flights detected, flight altitudes and detection distance.

Users can also delve into historical flights, searching by keywords such as flight number and device ID, and viewing flight-path records.

Heat Map Drone Flight Analysis

DJI AeroScope heat maps display the detection frequency and location distribution in the areas surrounding your asset or facility.

This lets you analyse the hotspot areas and take necessary action.

Advanced Drone Monitoring

Advanced Monitoring makes it easy for users to set up specific monitor rules, such as time and date ranges, customised monitoring areas, and choose warning alert methods.

You can also choose different options to monitor a drone's behaviour in your airspace. Want to know when a drone is too close for comfort?

Then select Monitoring Subject Appear in the Target Range, and a system warning will be triggered as soon as the monitored object appears in the planned monitor range.

The G8 and G16 systems send out email notifications, as well as on-screen visual and sound alerts. This means that AeroScope can be operated remotely and ensures that users do not need to sit behind a desk, waiting for a detection.

AeroScope as part of an Unmanned Traffic Management System

National aviation regulators understand that Remote ID will be a key component of future Unmanned Traffic Management (UTM) systems, which will simultaneously track drones and traditional aircraft in crowded airspace.

AeroScope played a key role in Operation Zenith, a recent large-scale test of UTM technology at Manchester Airport.

As an AeroScope specialist, Heliguy set up the system for the demonstration, which showed how AeroScope’s easy, accessible Remote ID information could be integrated into a UTM system, providing airspace managers with a full picture of drone and traditional aircraft movements in the skies.

As UTM systems move from the lab to the real world, AeroScope can be a key element in not only guarding against conflicts, but ensuring that all airspace users get fair and equitable access to the skies – unlocking the full potential for drones to help society.

Extendable masts for drone defence

Increase your observation capabilities.

Diverse Mounting Solutions

A mast can be a key piece of equipment in your drone defence strategy.

Drone defence technology, such as DJI's G8 and G16 AeroScope systems, can be mounted to a mast for a safe and secure solution.

HELIGUY.com™ has teamed up with Total Mast Solutions to offer extendable masts, which can stretch between 2m and 20m in height.

Being able to adjust the size of the pole provides a flexible option, to dynamically adjust the height of the drone defence system to met the specific mission.

Mounting a DJI AeroScope G8 or G16 to a mast which can stretch to 20m in height allows you to extend the field of vision and coverage area, enabling you to protect as much airspace as possible.

As an added bonus, Total Mast Solutions' masts are both portable and easily and quickly deployed; essential for ad hoc missions and one-off events and incidents.

The masts - constructed from 2mm anodised aluminium, for a robust, but light solution - are available from HELIGUY.com™, for either purchase or rent.

Heliguy Supplies Drone Detection To Gatwick Airport

Heliguy provided Gatwick Airport with a sophisticated drone defence system, which now forms part of the airport’s overall counter UAV capability.

The UK’s second busiest airport took action after suspected drone sightings in December 2018, which grounded more than 1,000 flights and impacted 140,000 passengers.

Gatwick chose Heliguy as its critical supplier and we installed the counter-drone technology, as part of a broader, comprehensive solution which protects the airport from a wide range of unmanned aircraft.

"Heliguy responded quickly to our initial request for drone defence in December and pulled out all the stops to make this happen.

Since then, we have worked closely with them to build part of the airport’s overall solution and they have provided wide-ranging support and expertise along the way.
With their help, as well as others, we are now able to provide leading-edge counter-drone resilience for Gatwick Airport."

DJI AeroScope, Supplied By Heliguy, Detects Drones At British Grand Prix

DJI AeroScope – supplied by Heliguy – was used to detect drones being flown illegally during the 2019 British Grand Prix weekend at Silverstone.

Northamptonshire Police and Northamptonshire Fire and Rescue Emergency Services Drone Team used the sophisticated drone-detection system, alongside other software, to help trace rogue unmanned vehicles within the 2.5-mile restricted zone around the circuit.

A small number of drones were detected, with two of them seized over the weekend – having been controlled by pilots on nearby campsites and nearer the circuit by remote pilots seemingly unaware of their responsibilities and limitations as a drone user.

"We were really impressed with DJI AeroScope.

It was easy to use and gave real-time information allowing the team the capability to respond in a timely manner, on one occasion so quickly the drone never took off and was subsequently turned off, but getting that high-visibility police presence made whoever was responsible think twice "

A layered drone defence solution for complete protection

Modern security requires a layered approach that keeps up with the evolution of drone technology.

To take drone detection to the next level and to have a comprehensive and all-encompassing strategy, a layered solution is an extremely effective course of action.

AeroScope is a sophisticated piece of kit and is the best in the business for detecting DJI drones and providing in-depth, real-time information about a potential UAV threat. However, AeroScope can only detect DJI drones.

This is nothing to be scoffed at though, as AeroScope works with all current models of DJI drones, which analysts estimate comprises over two-thirds of the global civilian drone market.

Because DJI dominates the drone market, it is essential that AeroScope is at the heart of your drone defence strategy.

But, it is also important to plug the gaps - and this is where a multi-sensor solution comes in, integrating DJI AeroScope with other solutions.

This is why our layered approach - using a mix of counter-drone technology from a range of industry leaders, such as BT, Advanced Protection Systems (aps), Operational Solutions Ltd (OSL), Rinicom, Altitude Angel, and OpenWorks Engineering - is so effective.

Our multi-layered solution can include a second RF detector, radar/3D radar, and an optical camera with up to four Detection Modules each providing 90° coverage and a powerful 360° PTZ camera to zoom in to the detected object to analyse its signature. All of these systems can be brought together using a sophisticated interface.

In essence, Heliguy Detect’s layered solution is scalable and flexible depending on the client’s needs.

Types  of drone defence

An overview on how different technologies will help defend your airspace against rogue drones.

Having a reliable counter-drone solution arms you with the knowledge that you will be protected from an illegally-flown UAS and you will be able to react quickly to any potential threat.

Here is a look at some of the anti-drone techniques which exist to fight back against an attack.

Drone Detection Methods


Heliguy Detect’s AeroScope solution, created by leading drone manufacturer DJI, is one tool for drone detection.

By intercepting the current communications link between a DJI drone and its remote controller, AeroScope is able to broadcast real-time identification information including UAV serial code, make and model, UAV position, speed, latitude and ground controller location.

This allows the operator to take mitigation action against the drone threat and at the same time dispatch law enforcement/security teams to apprehend the pilot.


Radar is another method of detecting and tracking drones.

Some advanced radar systems offer 360-degree coverage, fast-tracking and fully-automatic drone classification and flight-path monitoring.

Camera / Video

Cameras are another drone-detection technique, capturing the movement of UAVs, either using appearance-based, motion-based or hybrid methods.

The system has many commercial and defence applications, for example prisons, airports and places of interest, however, there are limitations.

Motion-based methods, for instance, can have difficulties distinguishing between drones and birds, while visual detection is dependent on the line of sight.


Acoustics fill a vital gap in proximity drone detection, as strict line-of-sight to target is not needed for positive tracking.

The drone can operate in urban canyons, cluttered areas, behind obstructions and in darkness or fog, out of range for radars and optics, but still within the earshot of an acoustic sensor.

Using hundreds of interconnected microphone elements, acoustic sensor units are able to establish a bearing and elevation to the target in real time using advanced digital-signal processing.


Thermal imaging can be used to detect drones. Tests have shown that, by using a thermal camera, it is possible to detect and, with sufficient database, even identify foreign UAV.

The main heat source comes from the drone’s batteries. Some investigations have shown that the maximum range of detection is shorter than expected.

Drone Defence Methods


Jammers are designed to disrupt a drone by blasting electromagnetic noise at radio frequencies that drones operate and transmit video at, and at a power level high enough to drown out any effective communication between the drone and its pilot.

This is known as RF-jamming and this method does not interfere with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands.

When a drone is hit with a jammer’s signal, the drone usually returns back to its origin point (unless GPS is also jammed), giving the jammer user the option to track the drone back to the pilot.

Sometimes the drones might even perform a vertical descent and land on the spot intact. Landing on the spot is also the general response from drones when both RF and GPS are jammed at the same time.

Jammers can be effective against drones over several kilometres away.

While jammers are generally restricted for use in many countries except by the military, police, and first responders depending on the laws, non-GPS jammers are legal in a number of countries.

It is important to look into the laws and regulations of the country and state that you are in to determine whether the use of a drone jammer is legal before operating one.


Perhaps one of the most obvious ways to stop a drone threat is to shoot them down. This isn't always a popular option though.

Numerous companies have produced hand-held or shoulder-mounted devices that can be used to fire nets at rogue drones, trapping them and preventing the blades from rotating, causing them to fall from the sky.

But such net-capture guns are more useful if used in conjunction with other detection technologies.


Lasers are another way of fighting back against a drone attack. Both the US and China have experimented with technology that can shoot down a device within seconds of locating it.

One method comprises a high-energy beam that locates and disables small drones from several miles away. This technology apparently uses infrared cameras that can work in low-visibility conditions, such as fog.

During 2018, China demonstrated a laser gun called the Silent Hunter, which can intercept drones with 'high accuracy'.


A more natural solution has been developed in The Netherlands - with police using trained eagles to bring down hostile drones.

The birds do this by latching on to the propellers with their talons, instantly disabling them.

Trainers say that the eagles see the UAVs as prey, so are not interested in attacking anything else when released. However, there have been issues, with reports that the eagles wouldn’t always do what they were trained to do.
