4DREAM, established in 2006, is a social enterprise that provides a variety of safety management solutions related to safety and privacy to provide ‘social contribution by developing technologies to respond to social issues in the safety field’. In the defense sector, based on advanced IT technology, we are contributing not only to civil-military technical cooperation in the drone sector, but also to the development of anti-military drone combat systems and the creation of a safe drone operation training environment. We are pioneering the field of drone Miles training safety management by systematizing a flight evaluation system suitable for the counter forces and a quantitative piloting ability verification procedure for the purpose of prior safety education for training personnel.
