GIS - Real Time Operating System

With the aim of developing the avionics system design and integration capability, which are among the critical technologies of GIS, nationally, a path has been developed for the development of the Safety Critical Strict Real-Time Operating System, which is an important step in the roadmap.
With this project, it is aimed to end the foreign dependence of safety critical system projects in line with national needs, to provide a scalable and sustainable safety critical embedded software development platform with the flexibility to meet the needs of domestic needs quickly, as well as to create a system that will be preferred for civilian embedded system applications thanks to its reducible features.

The operating system, developed in accordance with DO-178B Level-A processes, can be run in ARINC-653 mode, which provides safety critical application interfaces, or in POSIX mode, where PSE-51/52/53 operating levels can be selected if desired. Development environment activities such as configuring the operating system by selecting the operating modes, application development, debugging, event analysis, simulation can be done through the Integrated Development Environment developed on the Eclipse platform.

Developed in accordance with DO-178B Level-A processes, the Real-Time Operating System is designed in a modular structure to operate on different microprocessor families and different single-board computers. With the ASP (Architectural Support Package) and BSP (Card Support Package) layers provided, the hardware family supported by GIS is available for expansion.

ARINC-653 and POSIX interface compatibility have been tested with test environments developed separately, and the operating system, which has successfully passed these tests, has also proven its compliance with standards in this regard by communicating with other single board computers running on different operating systems. Other operating systems developed using these interfaces provide convenience in the transition to the integrated national real-time operating system.

GIS, which is of critical importance in terms of preventing the export of critical data with the national operating system in confidential projects, enabling full nationalization in embedded platforms, supporting the internationally competitive industrial sector thanks to reduced costs, and the formation of new SMEs, helps Turkey to reduce its foreign dependency in this field. plays an important role in reducing

HATS - Aircraft Tracking System

Aircraft flying VFR, such as helicopters, cannot be tracked at low altitudes with existing radar systems. Some helicopter accidents in previous years have revealed the necessity of continuous monitoring of aircraft flying at low altitudes. The Aircraft Tracking System-HATS, developed jointly by TÜBİTAK BİLGEM and the State Airports Authority (DHMI), will contribute to reaching emergency aircraft as soon as possible.


    • Continuous data collection, processing and recording
    • Redundant and expandable server architecture
      • Double redundant server stack
      • Redundant data storage
      • Double redundant firewall
      • Redundant network and power connections
    • Secure access via internal network with defined user and client authorization
    • Desktop clients supported with high performance GIS and vector maps
    • Continuous vehicle tracking and retrospective query opportunity arranged with authorizations
    • Ability to define authority groups and aircraft groups
    • Push-to-talk voice communication with aircraft
    • Automatic emergency declaration for aircraft that have lost communication
    • Emergency notification by e-mail and SMS

The Aircraft Tracking System consists of the Aircraft Tracking Device attached to the aircraft and the Aircraft Tracking Center, where the tracking of the aircraft is provided. With the Aircraft Tracking Device, the position, speed and altitude information of the aircraft are sent to the Aircraft Tracking Center periodically, and the positions of the aircraft on the map are updated in accordance with the incoming location data. Emergency aircraft are displayed in different colors on the map, and an audible warning is given for vehicles. When necessary, a push-to-talk style voice call can be made with the aircraft over GPRS.

Since the communication of the system is provided via both GSM and satellite networks, it is cost effective and reliable. Even if the connection is interrupted when the aircraft is in an accident or crash, it is aimed to be able to intervene in the aircraft in a short time with the last sent location.

In the future, it is aimed to apply the system to all aircraft performing VFR flights in Turkish airspace.

HATC - Aircraft Tracking Device

Developed jointly by TÜBİTAK BİLGEM and the State Airports Authority (DHMİ), HATC has internal and external impact sensors for automatic emergency notification. It has a switch for manual emergency notification. Warning lights provide visual feedback to the pilot for emergency and on-board test results. HATC uses the 28 VDC power line on the aircraft. It contains an internal battery so that it can continue its functions for at least 30 minutes in case of external power cut in an emergency. The internal battery is regularly recharged by an intelligent charging circuit to be ready in case of an unexpected power outage. A power loss encountered during the flight is considered as an emergency and reported to HATM.

  • The Aircraft Tracker (HATC) is the on-board component of the Aircraft Tracking System (HATS). HATC collects position, speed and altitude information from aircraft sensors. It periodically sends it to the Aircraft Tracking Center (HATM) via GSM and LEO satellite communication interfaces. HATC also allows for push-to-talk voice communication over the GPRS network.

    HATC has been approved by EASA with type certificate number 10045303.

    The HATC is designed to be placed on the aircraft operator console via four DZUS locking screws.
