SkyFence | Fixed Installation Drone Protection

SkyFence is an electronic countermeasures system which prevents drones from flying into or close to a protected location by disrupting its command and navigation radio transmissions; in any weather, day or night. It can be configured horizontally or vertically depending on the operational requirements.

As a system it uses multiple low-powered radio transmitters which are strategically placed around the protected site. When activated, they transmit a signal which is designed to overwhelm the drone’s radio transmissions. This breaks the control and video link between the drone and its operator.

SkyFence is fully programmable and can be activated via a suite of sensors or human input.


SkyFence causes no interference to other electronic devices.

SkyFence's Key Features and Benefits:

Scalable – The system is infinitely scalable to match the perimeter size of any installation

Automatic – Fully automatic ‘Detect, Decide & Effect’ function means no human input required

Integrated – Can be integrated into existing Security Management System

Monitored & Updated – If required the system can be remotely monitored and updated to ensure optimal  effectiveness

Versatile – Can be used to protect a range of fixed installations which need persistent drone defence

Cost Effective – Unrivalled performance for the price

Low to no collateral damage – Has no effect on internal or external communication systems

Effective – Will detect and stop 99% of commercial drones

Localised Effect – Highly precise

Protective ‘Roof’ – When in Vertical Mode ensures drones can’t drop down into facility

SkyFence is installed along an existing perimeter fence and creates an electronic ‘wall’ which extends into the sky.  An operator controlled drone is unable to fly through this wall.

By using Precise Antenna Technology (PAT) SkyFence reduces impact on other electronic devices and only affects the drone in the sky.

When minimising collateral electronic impacts is essential then SkyFence is the solution.

SkyFence’s Primary Field extends to over 500m in height above the panel meaning the drone cannot fly over the electronic wall.  The Secondary Field ensures that there are no gaps in the system.

SkyFence can be deployed alongside an automatic detection system like our AeroSentry or it can be manually activated by security staff.  Users have the option of upgrading existing drone detection technology with SkyFence or purchasing a complete system from us.  The system is scalable meaning that it can be deployed along almost any fence line.

A SkyFence system comprises of a number of panels and control boxes depending on the the length of permitter which needs protecting.  It is recommended that a panel is placed every 40m along the fence line.  Six panels form a ‘string’ which needs a power supply unit to provide it with control and power.  Each string can protect 240m in length.

SkyFence’s most prominent deployment is in Guernsey Prison where 24 panels have been used to produce an active ‘no fly zone’ over the prison estate.  Inside the prison a drone detection device is used to automatically activate SkyFence when a drone is near.  While active the drone is unable to fly in the prison’s airspace.

SkyFence is used alongside legislation which makes it illegal to fly above or near the prison.  The States of Guernsey have also amended legislation to allow for signal interference of the drone.
