Over the past fifteen years, the popularity and accessibility of Unmanned Aerial Vehicles, commonly known as drones, for commercial or recreational use have seriously surged. With Spynel's infrared thermal imaging technology, it is impossible for a UAV to be stealthy This figure is disturbing given the recent number of incidents involving UAVs flying over or landing on critical infrastructures all over the world - the White House, the Prime Minister of Japan's office, the Golden Gate Bridge, nuclear sites in France, prison facilities, etc.
Acoustic sensors or radars fail in detecting the low speed and low electromagnetic signature of small UAVs, making more modern technologies such as infrared technology the best option to prevent these new threats from harming people or destroying critical infrastructures.
Working in tandem with the Cyclope intrusion detection software, Spynel tracks an unlimited number of targets either airborne, terrestrial or maritime threats to ensure that no event is missed over a long-range, wide area surrounding. Basic classification of targets ground or airborne is based on elevation calibration and all air targets are represented by a small plane icon. Thermal imaging allows for day and night surveillance, but also guarantees the ability to view any object, even deemed as stealth, whether it is hot or cold.
The Visible Channel is a full HD camera with a continuous optical zoom x30allowing to zoom in on a threat. With this brand new continuous optical zoom, the user can keep an eye on the threat during the identification phase. The eyesafe Laser Range Finder provides the user with the exact distance of all detected threats on land, at sea or in the air, regardless of their size.

Test and Measurement. See alsoWith so many different anti-drone methods jostling for attention, understanding drone detection and neutralization can be an intimidating task. All the same, a handful of technologies have gradually risen above the rest and been adopted by the majority of airspace security providers.
The advantage of this style is that the signature or protocol of COTS drones is relatively distinct from other communications taking place on the same frequencies.
In a radio frequency-based drone detection set-up a passive radio frequency sensor captures activity on select frequencies of the RF spectrum and relays it to a computer where specialized algorithms compare it to a database of drone protocols.
What about more than one drone? With radio frequency detection, even if multiple drones intrude into airspace at a given moment, they can all be detected and tracked as long as they communicate with their pilot over the RF spectrum — which is the case with nearly every consumer-grade drone.
Drone Detection & Defense Systems
A particular advantage of RF technology is that certain sensor configurations allow an administrator to discover and track the location of both the drone and its pilot. Given the restrictions placed on drone interception methods, apprehension of the pilot is probably the safest, least complicated and most effective method of neutralizing drone threats at their source.
Despite all the advantages of a radio frequency anti-drone solution, like any technology it has its limitations. Autonomous drones pose perhaps the biggest challenge to an RF-based system since an utter lack of communication between the drone and its controller would eliminate all opportunities to detect it on the spectrum. But a truly autonomous attack — involving a drone able to navigate by GNSS without even sending back its video stream or telemetry information, spontaneously adapting to changes in the environment and avoiding unexpected obstacles — is extremely complex to orchestrate and therefore unlikely.
Barring any sudden technological breakthroughs, RF-piloted drones are likely to remain the device of choice for the majority of operators for the foreseeable future. Radar can provide effective detection of drone presence over a long range. It can be successfully paired with other technologies, such as RF or optics, to provide more thorough coverage if desired.
A radar system has a transmitter that emits radio waves called radar signals that are either reflected back or scattered by objects they encounter. But since drones are far smaller than any airplane or helicopter, they require a different approach. K and X Band radars are often used for low aerial surveillance, including drone detection, with X being preferable as its shorter wavelengths 8.
A Pulse-Doppler radar drone detection system emits periodic bursts of radio waves and measures the bends in the returning radar signal to estimate the distance, speed and characteristics of a detected object. Drones however are mostly made of plastic which is invisible to radar and only their metal cameras, batteries and motors provide a platform for the radar signals to bounce off of.
Drone Detection & Defense Systems
Drones are smaller than manned aircraft and tend to fly close to the ground which makes them very difficult for all but the most specialized radar to detect 6. Such systems do exist, but they often present additional issues such as cost, high-false alarm rate and potential interference 7 :. The initial outlay can be quite costly for a security administrator. But other costs are a result of the very nature of radar.
Thus, it consumes considerably more energy than a passive system. This also means that radar coverage can knocked out completely if its power supply is disabled by weather, sabotage or malfunction.
Like radar, optics can be successfully combined with RF technology to provide more thorough coverage. Optic detection uses cameras to spot intruding drones.The APP also records data including the drone type, ID and other information that can be used to document incursions and support apprehension and prosecution by local law enforcement. Multiple devices using the APP can create a crowd sourced network for wide area coverage and detection with real-time web based situational awareness displays and automatic warning of drone incursions via visual and audible alerts and text messaging.
HARRIER DSR drone surveillance radar is primary surveillance radar designed specifically for detection and tracking of small, low flying, non-cooperative targets in high clutter environments.

Interoperable Integrated Technology DroneWatcher and HARRIER systems can operate as a stand alone facility and force protection systems detecting and alerting perimeter intrusions by air, water and land.The only affordable drone detection radar combining degree coverage, fast-tracking, and most importantly; fully automatic drone classification. Birds actually. And even though we started with tracking birds, we validated our data with drones, in order to prove our radar tracking accuracy.
It can detect larger fixed-wing targets at a range of up to five kilometres, with smaller multi-rotor drones detected at up to three kilometres. Completely securing an area though, relies on more than just range detection. It requires flexibility and reliability. The output from multiple radars can be incorporated into one unambiguous picture, meaning a single drone causes a single alarm. Radars are expensive. And military radars are seriously expensive. And that goes for both the hardware and the software.
The radar display is a map-based interface Google Earth as standardcomprising easy to understand colour-coded tracks. Red tracks indicate drones and their flight path. Orange tracks represent suspected drones. Green tracks represent birds and other moving targets. All track types can be toggled on and off, and the track visualisations and colours are all user configurable.
Oh, and you can, of course, push our drone tracks and alarms, in real-time, to your own external security systems and command and control systems. We think Max is the most advanced avian radar of its time. In part, because it allows us to objectively measure and use risk as a performance indicator, rather than the rare occurrence of incidents. ROBIN systems are linked to our existing air defence radars to identify bird intensities up to kilometres.
That should be based on facts. Avian radar has the capability to provide unbiased facts and is thus a vital element for the decision making process. The successful operational outcome has proven that this can play a fascinating role in bringing together user interests and communities. Case Studies. About Us.

Send message.Drones with obstacle detection and collision avoidance sensors are becoming more prevalent in both the consumer and professional sectors.
This year, we have quite a few drones with collision avoidance technology. This obstacle detection and avoidance technology started with sensors detecting objects in front of the drone. Now the latest drones from DJI, Walkera, Yuneec and others have front, back, below and side obstacle avoidance sensors. In this up to date article, we take a quick view at the top drones with obstacle detection and collision avoidance technology. We also give you a brief overview of the type of obstacle detection sensors being used, including information on software algorithms and SLAM technology, which is used to interpret the images being scanned by the sensors.
There are also links and information if you would like to create your own DIY collision avoidance system. Surprisingly, there is not just one type of obstacle detection sensor being used by the drone manufacturers. Manufacturers are fusing these various sensors together to create the obstacle detection and collision avoidance systems.
The below obstacle avoidance drones contain from 1 to 6 directions of obstacle avoidance technology. We will review this list in more detail further along this post. The Skydio 2 was only released in October It has overlapping visual sensing meaning it has full obstacle detection.
The Skydio 2 was particularly designed for tracking people and subjects. The Mavic 2 have obstacle detection all 6 sides of the drone. The Mavic 2 can also fly around obstacles in front or behind it. We have more information on the Mavic 2 obstacle sensing system further down.
Click on the link above to watch videos on these latest DJI Mavic 2 quadcopters. It has 5 directions of obstacle sensing and 4 directions of obstacle avoidance, which is outstanding. Each drone is different with the more expensive drones been used for commercial inspections, photogrammetry and movie making. One of the best obstacle detection and collision avoidance on a small drone is the DJI Mavic Air, which was released in January It has 3 directions of collision avoidance of forward, backward and downwards sensing.
The Mavic Air has some terrific innovative technology and is a terrific small sized drone. You can read a full Mavic Air review here. Below, I explain the Mavic Air obstacle detection and collision avoidance technology in more detail, along with the other drones above. Less drone crashes is what everyone wants. For the drone owner, it is very easy to get carried away while flying. If you loose your bearings or concentration, you could easily fly backwards or sideways into an object.A drone, formally called as unmanned aerial vehicle, is an unmanned flying object.
It is primarily controlled by remote control or inbuilt intelligence for navigation. It is a prime example of how embedded systems work together to bring a complete system which can navigate, self-balance, attain height and transfer information with the remote user or machine.
Traditionally drones have been used for many defense and scientific applications such as reaching remote areas, surveillance, weather monitoring and delivering goods in tough conditions. In the recent times with the advent of low-cost, small-size and low-power embedded technologies drones are increasingly used in consumer applications. Drones are now used as toy, photography assistance, cargo delivery vehicle, pesticide spraying vehicle etc.
Drones are attracting significant level of interests from startups, students, system integrators, solution providers, e-commerce and technology providers. Drones are expected to make our lives better, safer and more efficient.
This article elaborate major advancements in drone sensor and lower power connectivity technologies which are key to its exponential growth in recent times. Drones are expected to be very precise in their movement, be stable, attain expected height and communicate effectively. So a typical drone should have following attributes.
Else it will lose its balance and fell down. The movement may be in terms of distance, velocity, acceleration, direction and altitude.
This applies not only to the outer material but also to the electronics which is used inside a drone. Today drones are powered by several sensors to monitor the environment. The data is used for variety of applications such as weather monitoring, agriculture etc. Drones can be controlled by simple smart phone, a remote controller and directly the cloud. Depending upon the use case a right connectivity solution should be used. Sometime drones use multiple connectivity solution for multipurpose use cases.
Core Sensors These sensors form the core part of drone and ensure its proper functioning and navigation. These sensors are accelerometers, gyroscope, magnetic compass and barometer sensor. Accelerometer Accelerometer is used to provide the acceleration force which the drone is subjected to in all three axis X, Y and Z. It also determines the tilt angle of drone in stationary position.
If the drone is stationary in horizontal position then its X and Y axis will give 0g output whereas z-axis will give 1g output.
If the drone rotate by 90deg on X axis then X and Z will give 0g and Y axis will start will start giving 1g. During the tilt X, Y and Z will give output which lies between 0 and 1g. The values can then be applied to trigonometry formulas to arrive at tilt angle of drone.
Accelerometer are also used to give linear acceleration in horizontal and vertical direction. This data can be used to calculate velocity, direction and even rate of change of altitude of the drone. Accelerometer is also used to detect the vibration which the drone is experiencing.
Accelerometer is a very important sensor in any drone as it provide critical inputs even when drone is in stationary position. Gyroscope Gyroscope sensor detects angular velocity in three axis. So it can detect rate of change of angle in pitch, roll and yaw. Gyroscope is a critical sensor even in regular craft. The change in angle information is used to provide stability to drone and to prevent it from wobbling.
The information from gyroscope is fed to motor control drivers to control the speed of motors dynamically to provide the stability to motor. Gyroscope also ensure that drones rotate at exact angle which is expected by user controls.
