Current Funded Projects

Smart Visual Guided Drone

In this collaborative work, we are building intelligent drones with fully visual navigation and guidance capabilities. We integrate AI-based visual target tracking and visual-inertial navigation into an autonomous agile drone to defend critical facilities such as airports where electronic warfare support, e.g. electroninc jamming, GPS-spoofing, etc., is not possible. The developed drones enable end-to-end autonomous operations with intelligent decisions without building any link with GPS and ground systems.

SRUS: Agile and SWARM Drones

We are partnering with HAVELSAN to develop agile drone swarms and carrier unmanned VTOL platforms, enabling broad UAV operations. ITU ARC fully designs and builds small-size drones with agile flight envelopes. These drones can navigate in GPS-denied environments using visual odometry and target tracking in addition to leader following. The unmanned VTOL platforms carry small-sized drones and provide tactical level information by utilizing their surveillance and SIGINT capabilities. The carrier platforms can also provide laser designation for coordinated operations. In this collaborative development, for VTOL platforms, the ITU ARC team provides controller, flight management, and navigation modules with their algorithms and avionics.

AI-based Aircraft Predictive Maintenance

We are investigating novel methodologies for predictive maintenance based on Big Data Analytics and Data Mining. With the collaboration of Turkish Airlines and Turkish Technic, we are building predictive maintenance is recognized by 66% of the airlines as one of the most prominent new technologies to have entered the market by 2020. Our aim of predictive maintenance is first to predict when a component failure might occur, and secondly, to prevent the occurrence of the failure by performing maintenance. Monitoring for future failure allows maintenance to be planned before the failure occurs, thus reduce unscheduled removals and avoid Aircraft-on-Ground (AOG).

START: Resilient ATM Network Management

In this project, we run research on applying information spreading process to model the uncertainty propagation over air transportation network. To construct the parametric model of the network, we utilize the real flight data of the European air traffic flow. The physical parameters of the network extracted from the dataset are transformed into a parameter set of the epidemic model to simulate the propagation of delay. Then, we build a control mechanism the infection rates ensuring the stability of the meta-population network, which means to manage the traffic flow between the airports, where the problem is transformed into an optimization and reinforcement learning problem.

FACT: Urban Unmanned Aerial Vehicle Management

The project FACT will bring a much-needed update to CNS technology and build the bridge between future U-space services (expecting fully digital and highly automated) and conventional ATM systems considering both technological and users’ perspectives. The main overall objective(s) of the project FACT is to increase safety, security, efficiency, and robustness of future air traffic environment through the development of integrated CNS functional architecture supporting the use of a common performance-based approach for CNS functions addressing the needs of a large spectrum of airspace users across varied operational environments. It will address and bring benefits for both existing and new airspace users, such as drones or urban air mobility.

Past Projects

Flight Trajectory Wind Error Recovery with AI

The project proposed to develop advanced algorithms to reduce uncertainty in weather forecast in trajectory prediction. The fundamental data set is the aircraft trajectories from the radar measurements that encapsulate information about the uncertain parameters such as wind vector. The aim was to build a probabilistic “wind map” to capture the wind estimation error and convert this sparse information into a complete wind map.

COPTRA: Combining Probable Trajectories

COPTRA's objective is detailed with three sub-objectives developed through three research work packages: a) define the concept of probabilistic trajectory prediction; b) define the probabilistic traffic concept and study how it can be constructed by combining probabilistic trajectories, using the probabilistic trajectory definition; and c) apply probabilistic traffic to Air Traffic Control (ATC) planning.

HETS: Helicopter Terrain Avoidance Support System

In this project, we developed a safe flight navigation algorithm for helicopter TAWS avionics, which supports pilot with visual guidance for low visibility and close-to-terrain operations. Specifically, the algorithm use the performance models, monitors the potential terrain collisions and issues alerts with visual guidance to the pilot. Moreover, the algorithm tracks the divergence of flown trajectory from the predicted one due to lack of partial state measurement, and provides real-time parametric system identification and pilot intent prediction.

AUTOFLY-AID: A Smart Cockpit System

AUTOFLY-Aid aimed to develop and demonstrate novel automation support algorithms and tools to the flight crew for flight critical collision avoidance using “dynamic 4D trajectory management”. The automation support system is envisioned to improve the primary shortcomings of TCAS, and to aid the pilot through add-on avionics/head-up displays and reality augmentation devices in dynamically evolving collision avoidance scenarios.

AI-based Real-Time Airspace Threat Detection: AI-Radar

In this project, we built AI-based real-time airspace monitoring and anomaly/threat detection models in order to provide safe air flight traffic. The model involves two layers, enabling to detect flight trajectory anomalies through processing individual flights and historical trajectory patterns. The individual flight trajectories are tracked through online flight performance clustering, allowing us to classify the aircraft types in the airspace. Historical flight trajectory bundles are identified for each flight operation, and the individual conflicts with these distinguished patterns are detected through artificial intelligence methodologies.
