As part of the IDET 2025 trade fair, a number of companies belonging to the Czechoslovak Group (CSG) will once again traditionally be among the exhibitors. Their joint booth and outdoor exhibition areas will form the largest display of the entire event. In addition to Tatra Export, representing the Tatra Trucks automotive manufacturer, companies such as Tatra Defence Vehicle, Excalibur Army, MSM Group, Karbox, Excalibur International, as well as Kinetic Group and Fiocchi Munizioni will be showcased. From the CSG Aerospace division, the exhibiting companies will include Retia, Eldis, Pocket Virtuality, ATRAK, and CS Soft.
At IDET 2025 in Brno, Retia will showcase its X-band mobile 3D radar system—an advanced, compact solution for very short-range protection against drones and unmanned aerial vehicles (UAVs). These radars feature fully electronic beam steering combined with a mechanically rotating head. In addition to UAVs, the system is capable of detecting aircraft, helicopters, and other aerial as well as ground targets.
Retia will also present the latest version of its ReTwis 5+ radar device, designed primarily for security forces. This small, portable radar can detect and track people and living beings behind non-metallic obstacles, whether they are moving or stationary. The ReTwis 5+ uses ultra-wideband (UWB) radar technology, known for its high resolution, resistance to jamming, and minimal interference with other radio systems.
A key innovation at this year’s exhibition will be the introduction of the Situational Awareness for Armored Vehicles (SAAV) electronic system, which incorporates elements of artificial intelligence. SAAV enhances the situational awareness of combat vehicle crews, enabling better assessment of battlefield conditions and early threat warning. By fusing data from multiple sensors in real time, the system reduces the cognitive load on commanders and crew members, automates target detection, and optimizes decision-making in combat.
Additionally, Retia will present a new command and control system for air forces, developed in cooperation with Israeli partner TSG Advanced Systems. This solution is being prepared for potential implementation by various clients around the world.
At the IDET 2025 trade fair, Eldis will showcase several of its next-generation radar systems through models and digital presentations. These include the RL-2000/MSSR-1 NG, a combined primary and secondary surveillance radar, and the PAR-NG precision approach radar—both part of Eldis's latest generation of products.
These software-defined radars were designed and developed to boost performance while simplifying operation. Eldis engineers achieved this by reducing the number of unique hardware modules and shifting many functionalities into software components of the system. As a result, the systems consume less power, which also lowers the demands on backup power capacity.
The set of airport radar systems can be supplemented with the ERDIS air traffic management software, offering a complete solution for civil and military applications.
Eldis will also present its newly introduced RL-3000 radar, a long-range 3D surveillance system. This software-defined radar delivers three-dimensional data for tracking non-cooperative aerial targets, representing a significant advancement in long-range airspace monitoring capabilities.
At the CSG Group booth during IDET 2025, Pocket Virtuality will present its Lumnio system, an advanced augmented reality (AR) solution designed to support the maintenance and servicing of military vehicles and other equipment.
Lumnio includes a comprehensive database of manuals and work procedures and is usable both in support facilities and directly in the field. Instructions—featuring descriptions, photos, videos, and 3D elements—are displayed through smart glasses directly in the technician’s field of vision, allowing for hands-free operation.
The system is also compatible with standard mobile devices such as tablets and smartphones. In addition to maintenance support, Lumnio is also used for training new personnel, making it a versatile tool for both operational and educational purposes.
