Thales Air Traffic Management system is in operation since 2000 to manage all air traffic movements in Greek airspace. In 2015, Thales was selected to upgrade this ATM system in a contract that includes hardware replacement as well as the supply and integration of the Multi Sensor Tracking System (MSTS) and other enhancements.
Since the 1990s, Thales has supplied numerous systems to the Greek civil aviation authorities, including primary radars, secondary surveillance radars, communication and navigational aids (navaids) systems.
