AUDS Anti-UAV Defence System

The only fully combat proven counter drone/UAS system in continuous military operations having over 700 confirmed kills

Chess Dynamics Inc. with its U.S. partners, have delivered numbers of integrated kinetic and non-kinetic systems in various deployed configurations, including military vehicles to meet urgent operational requirements. These advanced systems have been extensively trialled and tested, achieving TRL9 status in 2016 and now in active service from late 2017.

Chess and its partners have the system engineering skills and knowledge to incorporate AUDS into fully integrated solutions to meet the War fighter’s needs.

About the AUDS system:


AUDS Anti-UAV Defence System


AUDS (Anti-UAV Defence System) is a counter drone system that is designed to disrupt and neutralise unmanned aerial vehicles (UAVs), remotely piloted aircraft systems (RPAS) or unmanned aircraft systems (UAS) engaged in hostile airborne surveillance and potentially malicious activity. The AUDS system combines electronic-scanning radar target detection, electro-optical (EO) tracking/classification and directional RF inhibition capability.

AUDS is a smart-sensor and effector package capable of remotely detecting small UAVs and then tracking and classifying them before providing the option to disrupt their activity. The system may be used in remote or urban areas to prevent UAVs being used for terrorist attacks, espionage or other malicious activities against sites with critical infrastructure.

The AUDS Team brings together three leading British companies, each with the unique capabilities required to create an effective counter UAV system. The A400 series air security radars are able to DETECT small UAVs in all weather conditions, 24 hours a day flying in urban areas or near to the horizon. The Hawkeye Deployable System (DS) and EO Video Tracker, featuring both a long range colour camera and a high sensitivity Thermal Imager (TI), along with state-of-the-art video tracking technology, is able to TRACK the UAV and, combined with radar target information, classify the target. The operator is then able to make a timely and informed decision to use the smart RF inhibitor to selectively interfere with the C2 channels on the UAV allowing the system to DISRUPT the UAV’s mission. The smart RF inhibitor uses directional antennas to achieve maximum range of operation with minimum colateral effect.
