We are member
of CSG Aerospace

Company RETIA, a.s. is member of industrial group CZECHOSLOVAK GROUP and its division CSG Aerospace.

RETIA’s uniqueness lies in the extensive expertise of its specialists, who can solve complex tasks in all areas of the company’s activities.

Military and Security Systems

We develop, manufacture and integrate radar systems that provide an overview of the air situation.
These systems are used by ground air defense units.

As concerns the military and security field, RETIA’s main products are the modernization of radars and weapon systemsC4I2 command and control systemsmanufacturing radar technology, and installing and integrating special electronics.

For many years now, customers from the Czech Armed Forces, NATO countries and other armed and security forces around the world have been convinced of these products’ quality and benefits.

The successful modernization of the 2K12 KUB anti-aircraft system for the Czech Army and other NATO countries led to us winning other important contracts, namely the modernization of P-37 radars and other Soviet-made radar equipment for the Czech Army and P-18 radars for our foreign partners. Complete modernization involved a new design for the electronics layout, reduced life cycle costs and an extended lifespan.

The RACCOS system, developed by RETIA, has been used by the Czech Armed Forces for many years. This automated communication and information system provides command and control for air defence units (GBAD).

Using this experience, another successful product was created, namely a specialized mobile container workplace, which serves as a ground station for NATO’s sophisticated AGS system.

The ReVisor short-range radar presents its own radar technology. The ReVisor surveillance radar, with a range of up to 25 km, is mainly used for ground-based air defence (GBAD). It has a fast data refresh rate to identify and track air targets, including low and slow flying, small size (LSS) and unmanned aerial vehicles (UAVs).

The next generation is represented by the multi-purpose AESA 3D radar ReGuard with a range of up to 18 km and an altitude coverage of 3 km. It is designed to detect and simultaneously track ground and slow low-flying targets with a small reflecting surface (LSS, UAV). The radar scans the space using electronic beam deflection and comes with a fixed or rotating base.

RETIA has been successfully installing special electronics in command-and-control systems for ground forces for many years. Powerful information systems and microphone headsets, including the communication means, were installed in the Pandur and Titus vehicles and in the weapon superstructure of the DANA M2 self-propelled howitzer.

The ReTwis 5+ is a unique small portable radar that RETIA has developed for the security and armed forces. It can detect living beings behind a wall or a non-metallic obstacle. With such parameters as a range of 40 m, an extremely low weight and size, it is no wonder it has ranked among the world’s top products in portable radars.

RETIA’s strengths lie in the fact that it can adapt its products to customer requirements, or fully implement it with the customer plus the ability to offer its customers technology transfers.

ReDAT Recording Systems

In the field of telecommunications, RETIA has stood out
with its business division for ReDAT Recording Systems.

The division provides a very sophisticated system for recording voice, image and other relevant data, which are automatically analyzed so they are available to users in a clear and structured form. 

The highly modular system, with a wide integration potential, fully covers the recording needs both in the dispatching segment and in the ATM/ATC sector and at contact centres.

Our customers include major mobile operators, large banks, integrated rescue systems, rail management companies, air traffic control and successful commercial contact centres.
