Indra will refurbish and extend the air space surveillance network that controls Turkey’s air traffic. The contract, worth €38.5 M, was awarded by Turkey’s State Airport Authority (DHMI) and is to be concluded within three years. The new network will be equipped with 18 Mode S Secondary Surveillance radars that automatically interrogate aircraft for additional information regarding identification and flight altitude. It will also include 5 S-band Primary Surveillance radars that will cover Turkey’s whole air space.

The radar stations to undergo modernization are: Merzifon, Ankara, İzmir Adnan Menderes, İzmir Akdağ, Batman, Karaman Ermenek, Burdur Eğlence, İstanbul Yenibosna, Cyprus Ercan, Esenboğa Mira, Bahçe Akçadağ, Dalaman Nuribaba, İnebolu Göynük, Erzurum, Ağrı, Antalya, Trabzon and Kıbrıs Ağırdağı.

The radar systems will be connected with their corresponding control centers and will be integrated into their traffic control systems so that the centers can treat and properly present the information. By using this technology, the air traffic management capacity of the country’s airports can be extended while maintaining high levels of security.

Indra will also be responsible for the start up of the new Air Approach Control Centre at Trabzon airport, to the Northwest of the country, on the coast of the Black Sea. The company will supply its air traffic management system to the centre. The solution combines information from the radars, aircraft flight plans, radiogoniometers and meteorological systems. It also includes air-to-ground communication links and allows automation of a large number of repetitive air traffic control and flight management tasks.
