The Single European Sky ATM Research (SESAR) project was launched in 2004 as the technological pillar of the Single European Sky (SES). Its role is to define, develop and deploy what is needed to increase ATM performance and build Europe’s intelligent air transport system.
Established in 2007 as a public-private partnership, the SESAR Joint Undertaking (SESAR JU) is responsible for the modernisation of the European air traffic management (ATM) system by coordinating and concentrating all ATM relevant research and innovation efforts in the EU.
