An agreement for the procurement of advanced radio navigation systems for Greek airports was signed by Transport & Infrastructure Minister Kostas Karamanlis and French multinational company Thales in Athens on Friday. The minister met with Frenchman Patrick Defranoux, Thales Country Director for Greece, Cyprus & Eastern Balkans and CEO of Thales Hellas, who is visiting Athens to participate in the Delphi Economic Forum VI. As a manufacturer of aerospace technologies and defense security systems, Thales will provide 29 aeronavigational and landing systems, to be installed in the country's major and regional airports, at a cost of 16.3 million euros. Greece will thus be upgrading 25-year-old current systems, and also be aligning with the EU's Single European Sky (SES) initiative.
