African multinational air navigation service provider ASECNA has signed a $33 million order for eleven Thales secondary radar systems.

ASECNA provides air traffic management for 18 African states that cover an area one-and-a-half times the size of Europe, mainly in francophone West Africa but also Madagascar.

Signing the deal at the International Civil Aviation Organisation's Montreal headquarters, ASECNA director general Amadou Guitteye said that the radars will cover terminal areas for some of the region's 25 international airports. Five terminal areas were already covered. En-route surveillance is provided by automatic dependent surveillance - mode C, with air-ground communication by a combination of VHF radio and satellite-based controller/pilot datalink.

ASECNA provides ATM in six flight information regions, namely Antananarivo, Brazzaville, Dakar Oceanic and Terrestrial, Niamey and N'Djamena, through area control centres at those cities.
