Founded in 1981, e.sigma Systems GmbH has established itself as a leading specialist in the development of state-of-the-art training and simulation technologies for military and security applications. What began as a focused endeavor has evolved into a comprehensive provider of integrated solutions, delivering sophisticated systems to international armed forces, security agencies, and industrial clients worldwide. The company's journey is marked by a commitment to innovation, particularly in the realms of tactical command and control, air traffic control, and ground combat simulation.
