    (National Aviation University, 2020-11-27) Шевченко, Юлія Вікторівна; Shevchenko, Yuliya Viktorivna; Ayrapetyan, Anna
    In our country, despite difficult economic and geopolitical conditions, the development of unmanned aerial vehicles (UAVs) is taking place as part of the development of domestic aviation. All over the world, this area is being actively developed, and it has definitely been supported by domestic researchers. Unmanned systems are being actively developed in the geodesic, agro-industrial and aerospace industries, used in everyday life and have many prospects for their practical application. Researcher`s interest in this area has made it possible to achieve certain results in a short time, but there are still many unresolved issues. One important area of research is the problem of adapting the autonomous UAV to the external environment. The task is much more complicated if the UAV flies at low altitudes above a complex terrain. In other words, the external environment is unknown or little known and can change dynamically. These are current scientific and practical challenges that need to be addressed. Analysis of recent research and publications.

    Prospects of transport and logistics systems development in Ukraine
    (National Aviation University, 2020-11-27) Шевченко, Юлія Вікторівна; Shevchenko, Yuliya Viktorivna; Ayrapetyan, Anna
    Today, the transport sector of Ukraine is a significant and important segment for the country's economy, because effective and coordinated work of the whole transport system is the driving force for the overall development of the country. However, the existing competition in the market of transport services requires more and more new approaches to the development of transport relations, the creation of new technologies and improving the quality of services. The lack of centralized management does not allow for the integrated development of all modes of transport, as well as warehouse, terminal and other types of economy. In the conditions of European integration, the most effective direction of the transport sector of Ukraine can be realized through the formation of transport and logistics system of the country, which ensures the interaction of all participants in the transport distribution process in the organizational-economic, technical, technological and information aspects during the movement of cargo flows, as well as to take a competitive position in international markets of transport and logistics services .
