CS SOFT a.s. is more than 20 years on the SW development market for the aerospace industry. Despite starting as a small company, the company moved into its present form with several research centers with advanced processes and methods of development and production of software tools that lead to the high safety standards and product dependability. • Systems for Air Traffic Control. We develop and manufacture systems for area control (ACC), approach services (APP) and tower services (TWR). Processing of the flight plans data and surveilance data is necessary for keeping view about the air traffic, flight trajectory computations, evaluation of conflicting trajectories, calculations and reporting procedures for regulating operations with the coordinating partners etc. • Auxiliary systems for airports. Data exchange between separate units of the airport, communication between air traffic control and airport. The systems provide outputs for particular handling companies and dispatching operations of airlines. Supplying data for information boards. The main tools that help CS SOFT to keep high standard of product safety and dependability are strictly observed rules of ISO 9001:2008 and supplier standards for software development such as IEEE 12 207. CS SOFT gained the support from the European Structural Funds to support technological development and it very closely co-operate in development projects with Czech leading technical universities.
