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.

Since 2018, CS SOFT has officially become a member of holding enterprise CZECHOSLOVAK GROUP. The newly established CSG Aerospace division includes several Czech and Slovak companies operating in the field of aerospace. There are also other renowned civil and military ATM and Radar providers such as Eldis, Retia and MSM Group. 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.


Personnel & Company

CS SOFT is a company that keeps its word

In terms of internal company policies, we would like to remain known as the company that complies with all the laws and regulations in all areas of our activities. In terms of employer-employee relationship, the company wants to make sure that all the employees are being treated well, with respect and as equals. Hence, we would like to continue improving the current work environment and working conditions. In CS SOFT, we enforce positive relationships and fair treatment both inside and outside. 


Work ethic & Expertise

CS SOFT: Flexible subject matter experts in ATM solutions

To keep up with the tough competition in our area of business, we are striving to become a lot more effective compared to the well-established OEMs. CS SOFT’s main strength lies in the fact that we are capable of implementing complex and highly customized solutions quickly while maintaining the highest level of quality and safety of our products. As for the future, we want to keep improving this capability and position ourselves in the market as the “go-to” experts on complex ATM solutions requiring a high degree of customization.   


Quality Assurance

CS SOFT guarantees safety-critical SW development and respective documentation

We certainly want to deepen the implementation of the ED-153 critical software development and SAM methodology. Considering our long-lasting experience in the field, we are aiming to provide consulting services as well.

Research & Development

Innovations in CS SOFT

Given our ambition to become a dark horse in the ATM market, we have been investing heavily in R&D and will continue to do so for years to come. In the near future, we are planning to introduce the end-result of our extensive work that will give us an opportunity to become even more competitive. By being active participants in The Single European Sky ATM Research (SESAR), we will continue sharing our know-how to improve performance of 4D Trajectory calculations.
