DIDIT stands for Distributed Detection, Identification and Tracking of small unmanned aerial vehicles (UAV), which most often are drones.
The initial idea for DIDIT originated in 2016 when small drones became a mass product and first incidents caused by clueless, careless or criminal (3C) drone pilots were registered. Following the initial idea, various Proofs of Concept (PoCs) were initiated and further modular development took place over a period of several years.
Now DIDIT is a multi-sensor system, and its modular design allows scaling according to the customers’ needs, as well as integration of new types of sensors in the future.
The components of the current system are a central processing unit fusing the various sensor data, an array of static cameras with short range for monitoring of court yards, rotatable and focusable PTZ cameras with long range and radio direction finders. All components, apart from the integrated PTZ camera, are the intellectual property of Telespazio Germany. The integration of micro-doppler radar is prepared through the implementation of the Asterix protocol.
Continuous innovation and improvement
In 2021, the second frequency band (5.8GHz) was integrated as monitoring of only 2.4GHz was not sufficient anymore due to the evolution of drone communication protocols. Another new feature implemented in 2022 is the measurement of the height of a detected drone as the third dimension of its position, making DIDIT stand out even more.
The use cases for the system are vast. However, most implementations serve to protect prisons, airports, satellite antennas campus and energy facilities. The system is also used on a temporary basis to assess risk and threat levels on specific premises to decide on the need for continued protection.
