Air traffic control systems and training

156 companies across 46 countries. Updated 5 November 2026.

Companies in this category supply the equipment, software and training behind air traffic control. That covers surveillance and navigation systems, controller working positions, voice communication, flight data processing, mobile and temporary control towers, and the simulators used to train tower and radar controllers. Customers are air navigation service providers, airports, military air bases and ATC training academies.

ATC equipment has to meet ICAO standards and be accepted by the national aviation authority before it goes into operational use, so ask suppliers which systems are already in service and with whom. For simulators, check how closely the software can model your own airspace, procedures and traffic levels. For training providers, ask about instructor experience and whether courses lead to recognised licences or ratings.

Companies here are based across the United States, Canada, the United Kingdom, Spain, Switzerland, Austria, Belgium, Sweden, Iceland and Australia, among others. The category includes both equipment makers and national air navigation service providers.

  • Adacel, simulation and training business with a base in Orlando
  • Micro Nav Ltd., builds air traffic control and defence simulation systems
  • Frequentis, Austrian maker of voice communication and information systems for air traffic control
  • Indra Sistemas, Spanish technology and consulting company
  • Skyguide, Swiss air navigation service provider with its head office in Geneva
  • Entry Point North, air traffic services training provider with centres in Europe
  • Intersoft Electronics, Belgian maker of radar subsystems, drone detection and test equipment
