Airport Traffic Control Software (HTKY) is an air traffic control system project developed by the Air Force Command (Hv.KKlık). HTKY is designed in accordance with the International Civil Aviation Organization (ICAO) and EUROCONTROL standards.

HTKY is a comprehensive air traffic control software that incorporates a number of features and functions. These features include processing of surveillance resources, processing of flight data, security and network alert functions, controller operating position, electronic flight strip system, incident analysis, monitoring and control capabilities, and redundant system architecture. HTKY is designed to ensure the safe and efficient operation of air traffic service.

HTKY offers advanced air traffic control functions to users using new technologies and user-friendly graphical interfaces. The project aims to develop HTKY in accordance with the DO-278A AL4 standard. In this way, it is aimed to perform air traffic control at airports at a safer, more effective and advanced level.

With the ongoing installation works within the scope of HTKY's R&D project, a modern and up-to-date air traffic control software required by the Air Force Command will be obtained. This project is an important step that will contribute to raising safety and efficiency standards in the aviation industry.

MILSEC 4 - Secure IP Terminal


While the MİLSEC-4 terminal offers an up-to-date solution for next-generation secure communication (voice, data and video) in IP networks, it provides an uninterrupted communication service by maintaining the compatibility of secure voice communication in PSTN networks with PSTN secure phones in use.

Configuration, surveillance and software update processes of MILSEC-4 terminals are carried out securely remotely using the Security Management Center (GYM). MİLSEC-4 terminal is capable of IP Network Key Loading (IPAAY) through secure communication with GYM without the need for an additional device.

MİLSEC-4 terminals are interoperable with MİLSEC-1A and MİLSEC-2 phones and offer the opportunity to replace MİLSEC-1A and MİLSEC-2 phones without interruption in the gradual transformation of PSTN networks to next generation IP networks.
