About Us

CS SOFT is a traditional, state-of-the-art provider of Air Traffic Management and General Aviation solutions. Over the past 30 years, the company has evolved from a small Czech-based business pioneering in ATM software into a dynamic European company with advanced software development methodology, extensive experience, rich product portfolio and successful civil and military installations on four continents. Our strong emphasis on flexibility and customer orientation enables us to deploy customized and reliable solutions, which are fully compliant with the industry recommendations and regulations, at a cost that may actually pleasantly surprise potential business partners.

Company CS SOFT is a member of the industrial group CZECHOSLOVAK GROUP and its division CSG Aerospace. There are also other renowned civil and military ATM and Radar providers such as ELDIS Pardubice, RETIA, or ATRAK. Jointly, we are able to cover a wide portfolio range including flight data processing systems, surveillance data processing systems, controller working positions, ATC simulators, radars and sensors, recording systems, mobile towers, and much more.

Main Areas of Activity

We, at CS SOFT, are fully aware of the tremendous responsibility that we have being a provider of ATM and GA solutions. With this in mind, we have designed our solutions together with the subject-matter experts to ensure safe and seamless flow of air traffic and smooth and cost-effective airport operations.

Our team specializes in designing, implementing and maintaining systems for air traffic control centers (ACC), approach (APP), tower (TWR) and flight information services (FIS) and 2D and 3D Simulators. The complete ATM systems and stand-alone modules assist in processing of flight plan data and surveillance data, which are essential for accurate display of air traffic situation, flight trajectory computations, evaluation of potential conflicting trajectories etc. Simulators follow the concept of Hi-Fi (high fidelity). In fact, they accurately copy controller’s workplace (interface, environment, communication with pseudopilots etc.) to provide the highest quality training possible.

CS SOFT has also developed interconnected tools enabling secure (multi-stage) and comprehensive distribution (sorting, filters, etc.) of sensitive surveillance data between various airport entities such as emergency service units, handling agencies, airport operations etc. The tools offer a possibility to display the data, access an archive, replay the stored data just to mention some. The functionalities could come in handy, especially when dealing with the authorities.
