The object of this study is the process of segmentation of images from unmanned aerial vehicles. It was established that segmentation methods based on k-means and a genetic algorithm work qualitatively on images from space observation systems. It is proposed to use segmentation methods based on k-means and a genetic algorithm for segmenting images from unmanned aerial vehicles. The main stages of image segmentation methods based on k-means and genetic algorithm have been determined. An experimental study of segmentation of images from unmanned aerial vehicles was carried out. Unlike known ones, image segmentation by a k-means-based method that successfully works on images from space surveillance systems cannot be directly applied to image segmentation from unmanned aerial vehicles. Unlike known ones, image segmentation by a method based on a genetic algorithm that successfully works on images from space surveillance systems also cannot be directly applied to image segmentation from unmanned aerial vehicles. The quality of segmentation of images from unmanned aerial vehicles by methods based on k-means and a genetic algorithm was assessed. It was established that: – the average level of first-kind errors is 70 % and 51 % when segmenting an image from an unmanned aerial vehicle using methods based on k-means and a genetic algorithm, respectively; – average level of second-kind errors is 61 % and 43 % when segmenting an image from an unmanned aerial vehicle using methods based on k-means and a genetic algorithm, respectively. It was concluded that further research must be carried out to develop methods for segmenting images from unmanned aerial vehicles.
В роботі проведено аналіз сучасного стану існуючої лабораторної бази бортових інформаційно-вимірювальних комплексів та реєструючих систем, які застосовуються для збору, обробки, відображення параметрів і характеристик дослідних зразків озброєння та військової техніки різного функціонального призначення, їх складових частин з метою контролю функціонування, контролю змін параметрів та визначення помилкових дій екіпажів на об’єкти випробувань. Метою статті є аналіз сучасного стану лабораторної бази бортових інформаційно-вимірювальних комплексів і реєструючих систем та визначення загальних вимог до систем бортових вимірювань для проведення випробувань озброєння та військової техніки різного функціонального призначення. Методом проведення дослідження є системний аналіз. Розглянуто характеристики означеного обладнання та варіанти розміщення і комутації у складі дослідного зразка.

Ukraine's European and Euro-Atlantic course requires the implementation of a number of normative documents, including documents in the field of metrology and metrological activities. This demands the adaptation of existing and development of new regulations. The study examined and analyzed national standards adopted by the acceptance of NATO STANAG 4107. NATO Quality Assurance Standards recommend verification, validation and metrological confirmation for measuring equipment used in the design, development and manufacture of armaments and military equipment. An analysis of the definitions of the terms "verification", "validation" and "metrological confirmation" in different standards and in international and interstate dictionaries of metrology is carried out. Processes of verification, validation and metrological confirmation are offered taking into account the latest changes in the field of metrology and metrological activity, tests of armaments and military equipment and metrological support of tests, as well as some legislative acts of Ukraine in the field of technical regulation. Conformity assessment is used in international practice and in Ukraine to prove compliance with the established requirements. The analysis of the term "conformity assessment" is done in the article. The process of proving the fulfilment of the set requirements for checking the compliance of products with the requirements of technical regulations for measuring equipment used in the field or outside the field of legally regulated metrology is explained. In order to improve the regulatory framework of the metrological support system in the field of defence and harmonization of normative and guiding documents to modern requirements, it is proposed to develop "Technical regulations for measuring equipment of general military and special purpose" and "Methods of metrological confirmation of measuring equipment for testing armament and military equipment”. The time period for implementation of NATO standards in the field of development and production of armaments and military equipment was also taken into account.
The article highlights the main aspects and features of the algorithm of aviation equipment operation "condition-based" with the use of ground technical means of control and on-board measuring systems and the formation of decision- making principles for further operation of aircraft. To develop methods of technical diagnostics of any technical equipment, it is necessary to identify which parameters characterize its condition and reliability as well as to establish diagnostic criteria and limit values of the controlled parameters. Depending on the nature of the parameters being controlled, there are parametric and physical methods of diagnostics. Based on the results of the diagnostics, we must get a straight answer: whether or not it is necessary to perform repairs or maintenance of the equipment being tested, taking into account the ensuring of failure-free operation before the next diagnostics. Currently, a large number of different measuring equipment that can measure signals that meet the parameters of the object of control and diagnostics are successfully used to objectively determine the technical condition of aircraft. The use of the laboratory for technical diagnostics of aviation equipment in conjunction with on-board measuring systems will provide an opportunity to make a quality technical diagnostics and reasonable conclusion to decide on further operation of the sample of aviation equipment. The use of mentioned laboratory will also predict the occurrence of failures of aviation equipment systems and units. Only a comprehensive approach to the technical diagnostics of aviation equipment with employment of all means of technical control (ground, on-board) will prevent sudden failures of aviation equipment systems.
