Autonomous and automatic air-to-air refuelling

**A pályázat célja és várt eredménye** Scope: Air-to-air refuelling enhances military operations by enabling long-range missions. Refuelling currently requires manual coordination between tanker operators and receiving pilots, which is complex and labour-intensive. Automated air-to-air refuelling solutions are expected to reduce workload and increase safety for both crews, while also being essential for future unmanned aerial systems. The objective of this topic is to explore the development of sensor systems, in particular hardware and sensor fusion, to enable accurate relative navigation between tanker, receiver and refuelling systems, even in adverse conditions. In addition, enhanced optical sensors, advanced image processing, flight control algorithms and pilot assistance interfaces will play a crucial role in improving the docking and refuelling process, increasing safety and time efficiency. This topic contributes to the STEP objectives as defined in the STEP Regulation in the target investment area of defence technologies.
