The CLEARSKY Drone Threat Management system has the capability to detect drone activity from up to two kilometres away. The above image demonstrates the system in action, showing four drones being detected at an airport. This technology will soon be deployed at Bristol Airport.


large public venues, airports and utility facilities from the unpredictable threat of unauthorised and malicious drone usage. With the capability to detect drone activity


The immediate dangers from drones


include potentially interfering with civil aircraft, damaging electricity or communication cables, and theft performance rights issues at live events, so protection is a priority. Drone misuse, unintentional or otherwise, is on the rise as more and more people deploy them. Figures from the Civil Aviation Authority show that British consumers purchased 530,000 drones in 2014 and that over the Christmas period in 2017, a fur ther 1.5 million were anticipated to have been sold. As drone sales continue growing exponentially, the requirements of infrastructures critical to the UK economy must be considered and their relevant authorities must be prepared for an appropriate and immediate response.


A sAfe pAir of hAnds


Developed in response to the significant rise in drone incidents, telent and Digital Global Systems (DGS) have come together to deliver their CLEARSKY Drone Threat Management system. Using passive wideband monitoring, the system has the ability to protect stadiums,

from up to two kilometres away, any associated potential threats can be easily and appropriately responded to. In addition, it can also locate the drone operator, monitor the flight path that the drone is under taking and identify the type of drone. The easy-to-use system – which does not require hours of training for the controller – also allows this information to be easily shared with on the ground teams responding to an incident. CLEARSKY uses passive wideband radio


frequency (RF) monitoring rather than radar, which means it does not interfere with other equipment and radio-based services. Unlike other products on the market the solution monitors a wide range of spectrum from 50 MHz to 6 GHz, to monitor both the commercial drone frequencies and outside the normal range to detect modified drones. This patented technology also automatically captures, interprets, locates, and aler ts on rogue wireless signals, helping to detect any unauthorised personnel operating in restricted areas. This ensures system users are able to capture and store threat data quickly so that the authorities can also use it effectively as evidence for any legal proceedings that may arise. Following a successful three-month pilot


project at Bristol airpor t, local police and other security agencies, telent and DGS were chosen by the team at Bristol airpor t to supply CLEARSKY, marking the first UK deployment of the system. As one of the ten busiest passenger hubs in the UK, the


airpor t’s security staff and local police will rely on CLEARSKY to accurately detect, identify and monitor unauthorised drone activity in and around the airpor t. More so, it will allow the airport to pinpoint


the location of both the drone and drone operator and this information can be shown on a control room screen (see above) or via a mobile application for officers responding to the incident. This eliminates the need for manpower-intensive searches over large areas and allows relevant authorities to quickly and efficiently respond to drone incidents.


implementing the right strAtegy


The best response for a drone attack is detection. This means organisations need to ensure they have the right tools and technology in place to protect their assets from the unpredictable threat of unauthorised and malicious drone usage. Looking ahead, as the devices become more commonly used, stadiums, large public venues and airpor ts need to star t investing in drone management technologies, before they find themselves at the forefront of a drone attack. As technologies and ar tificial intelligence


continue to move forward, having the right strategy in place to protect your organisation is crucial. Following the Gatwick drone attack, drone security has become a much higher priority for airpor ts and for the event sector. Whether used for good or bad intentions, the rise of drone usage means they will be increasingly more prevalent on both the runway and in everyday life.
