Abstract: Problem Statement. In the conditions of the growing need for environmental monitoring, the creation of compact and energy-efficient meteorological stations for measuring microclimate parameters is an urgent task. Modern solutions often require high energy consumption and complex infrastructure, which limits their application in autonomous systems. Purpose: The aim of the work is to improve the energy efficiency of an autonomous weather station based on ESP32, providing temperature and humidity monitoring with real-time data visualisation. Methods: the autonomous weather station is built on a modular architecture including SHT31 sensor and ESP8266 microcontroller for metrics collection, ESP32 microcontroller for data processing and transmission via MQTT protocol, and Node-RED software platform for data visualisation. To ensure autonomy, an optimised power supply scheme is implemented using a lithium-ion battery, TP4056 charging module and ESP deep sleep mechanism. Novelty: in contrast to similar solutions, the presented weather station is highly energy-efficient and modularly flexible, allowing it to adapt to different usage scenarios. The use of energy saving combined with optimised data transmission via MQTT minimises energy costs and increases system stability. Results: A compact weather station with reliable data acquisition and transmission was developed and tested. Temperature and humidity parameters are displayed through an interactive data visualisation panel in Node-RED, providing graphs of changes and current metric values. The autonomy of the device is increased due to the energy saving mode and optimised power supply scheme, which allows the system to be used without frequent recharging. Practical relevance: the developed design can be used for microclimate monitoring in indoor environments, agricultural facilities and remote areas. The use of available components and open-source software makes the system cost-effective and easy to implement.

Abstract: Problem Statement. In the context of rapid digitalization of the economy and public administration, ensuring the information security (IS) of critical information infrastructure (CII) has become an increasingly urgent task. CII includes facilities that play a key role in the functioning of vital sectors of society such as energy, transportation, healthcare, industry, and others. As these systems grow in complexity, the need arises for advanced technologies to ensure their protection. One such tool is the use of digital twins (DTs), which enable the modeling of threats and the testing of security measures. However, the integration of DTs into IS tasks within CII encounters a number of challenges that must be addressed for the effective implementation of this technology. The aim of this study is to identify the key challenges associated with the use of digital twins in the context of CII information security. Methods. The research employs the analysis of standards, classification of problems by category (technical, organizational, legal), and evaluation of DT usage scenarios within CII. Novelty. This work identifies new aspects of DT application within CII, particularly related to model characteristics, as well as issues of verification and integrity control of digital models. Security concerns are addressed, including risks associated with open APIs and telemetry channels, which may serve as vectors for attacks. A set of measures is proposed to overcome these challenges, including the development of regulatory standards for DT usage and the enhancement of professional training. Results. Key challenges have been identified and classified into the following categories: technical, security-related, organizational, legal, and those arising from incorrect usage. Each category encompasses specific issues, the consequences of which range from modeling errors and reduced protection efficiency to threats of critical infrastructure compromise and loss of trust in the technology. Theoretical / Practical Significance. The results of this study contribute to improving approaches to ensuring the information security of CII through the use of digital twins. The proposed recommendations for addressing identified challenges can be used to enhance the reliability, safety, and effectiveness of DT implementation and operation in CII systems.
Keywords: information security, critical information infrastructure, digital twin, data synchronization, threat modelling.

Abstract: Problem Statement. The paper addresses the problem of local positioning of unmanned aerial vehicles (UAVs) under conditions of limited accessibility to global navigation satellite system (GNSS) signals. The purpose of the study is to quantitatively assess the accuracy of two different UAV positioning methods based on range measurements and varying configurations of ground-based infrastructure. Methods. An analytical assessment of geometric factors affecting coordinate estimation accuracy is conducted. A field experiment program using reference GPS coordinates is developed for the calibration and validation of the obtained data. Numerically substantiated requirements are formulated for the placement of ground stations and measurement parameters. Results. It has been established that coordinate accuracy is strongly dependent on the relative positioning of ground stations and the flight altitude of the UAV. Functional dependencies between positioning error and key configuration parameters are derived. Quantitative criteria for the applicability of each method under specified conditions are obtained. Novelty and Practical Significance. For the first time, quantitative estimates of the applicability conditions for two local positioning methods in GNSS-denied environments are presented. The obtained results can be used in the design and preparation of field experiments for UAV navigation systems in safety-critical applications.
Keywords: local positioning, unmanned aerial vehicle, range-based method, angle-and-range method, navigation without satellite signals, field experiments, coordinate error, positioning accuracy assessment, reference coordinates, geometric configuration of ground stations, time synchronization, radionavigation measurements, positioning method comparison.
