ObjectivesThe aim of the study is to increase the effectiveness of unmanned aerial vehicles (UAVs) in the context of destabilising meteorological factors on the basis of an identification of links and patterns of unmanned aerial vehicles operating in difficult weather conditions.MethodsIn this work, in order to account for the effect of meteorological factors on the effectiveness of unmanned aerial vehicles, the methods of system analysis, mathematical modelling of atmospheric phenomena and processes, as well as probability theory and statistical assessment, were applied.ResultAn analysis of open literature sources devoted to the issues of operation and practical application of unmanned aerial vehicles (UAVs) under the influence of environmental factors was carried out. A classification of destabilising influences (DI) affecting the performance of a UAV flight mission is developed and presented. The dynamic probabilistic indicator, which, in characterising the dynamics of UAV functions as a complex technical system is referred to as “time efficiency of the UAV flight mission”, is substantiated. A methodology for estimating the dynamic efficiency indicator of the UAV’s functionality during the performance of a flight mission (FM) underDI conditions is developed on the basisof a probabilistic model of the conflicting interaction between UAV and DI. Strategies for selecting the trajectories of flights around local zones in which UAVs can be influenced by DI are given. To estimate the DI intensity and determine the size of the local disturbance zone, a mathematical model is proposed, whose application makes it possible to improve the UAV functioning under complex meteorological conditions (CMC) by taking into account the information on the space-time variability of dangerous for UAV weather-related phenomena (DWP). In the process of constructing the UAV functioning model, the use of conflict theory methods permitted adequate models for the analysis and evaluation of the dynamic efficiency indicator of the UAV functioning during the performance of FM in DI conditions to be developed, as well as the patterns of meteorological factors influencing the effectiveness of the UAV application to be revealed.ConclusionThe methodology proposed in the article makes it possible to increase the effectiveness of unmanned aerial vehicles (UAVs) under complex meteorological conditions by a time index of 20-30% as compared with traditional approaches.

The analysis of foreign experience in the use of robotic technological systems (RTS) shows that there are many possible areas of their practical application in the activities of state enforcement agencies. In the activities of the Russian police small-sized ground-based robotic systems and unmanned aerial vehicles have been used, which expand the capabilities of the internal affairs bodies in the course of resolving official tasks. The article presents the current state of the use of RTS in the Ministry of Internal Affairs of Russia, discusses the main problems to be solved, and considers the prospects for development of police robotic systems. The scope of use of RTS for various purposes is determined, depending on the application environment and the method of basing.

This paper deals with the issue of the possibility of using unmanned aerial vehicles in fire and rescue services in several common problematic situations in which these rescue units operate. In the introductory chapter, the work defines factual terms and definitions related to the categorization of unmanned aerial vehicles in connection with the active legislation of the Slovak Republic and chronologically describes their historical development. Subsequently, it analyzes the current state of the issue in the Slovak Republic, and then compares it with the state of use of unmanned aerial vehicles in rescue services of the same purpose abroad. The main task of this work is to design and evaluate a possible solution to this issue. Other goals of this work include the creation of a theoretical base, which can be used for the practical application of the proposed solutions for the use of unmanned aerial vehicles of fire and rescue services.

This paper discusses potential applications of unmanned aerial vehicles (UAVs) for disaster man age ment. Based on the current state and diversity of research, there is considerable evidence to sup port the strategic investment in UAV technology to develop new and enhance existing operational capabilities. When developing these capabilities, it is essential that officials understand a range of vari ables that will influence the development of a concept of operations for particular types of disasters. As the technical capabilities of UAVs exceed the permissible use of this technology, public safety officials and agencies will have to work closely with national airspace regulators to ensure that these responses are safe and do not endanger other aircraft. The community's attitude and perceived risks will also influ ence the potential use of UAVs for disaster management. It is essential that officials address these concerns and build in safeguards to protect against any breaches of privacy and individual rights.

In the periods of economic crises, the golden reserves of the country become a guarantee of its financial stability. In total gold and currency reserves the specific weight of the gold has a significant part. The current state of the gold mining sector does not provide the sustainability of its own development in the future. Scientific and technical development in the field of geological exploration is the important resource of gold mining growth and competitiveness.

A huge improvement in technology of unmanned aerial vehicles (UAVs), usually called drones, and their wide both civilian and military use has been observed recently. For it new countermeasures are undertaken to prevent air space violation in the vicinity of airports, critical infrastructure and mass events. Drones used to smuggle substances through the borders and to the penitentiaries are another threat. This paper presents the state of art in the systems dedicated to capture the miniature UAVs, and evaluates the methods used up to now, and points out the most perspective directions for drones’ neutralization systems.

The paper presents a brief analysis of the potential use of hydrogen-oxygen low-temperature fuel cells with proton-exchange membrane fuel-cell stacks as power sources for the construction of drive units powering unmanned aerial vehicles. Hydrogen storage methods are discussed. Characteristics of selected aspects of monitoring the electrical and non-electrical operating parameters of a drive unit with fuel cells were investigated, with respect to the fuel cell, fuel-cell cooling system, and gas reagent supplying the system with hydrogen and air. Hydrogen fuel consumption for the production of electricity and purification, or so-called purge, was analysed. Based on the results of laboratory tests of the parameters of a generator with fuel cells, an exemplary method of monitoring operating parameters and controlling power sources involving fuel cells is proposed.
