The Earth's aerospace monitoring (ASM) systems use state-of-the-art integrated information technologies that include radio-based detection and surveillance systems using telecommunications. One of the main tasks of ASM systems is to increase the efficiency of decision-making necessary for the timely prevention, detection, localization and elimination of crisis situations and their probable consequences. Modern conditions impose stricter requirements for efficiency, reliability and quality of the provided video data. To ensure compliance with the requirements, it is necessary to provide the appropriate capabilities of the onboard equipment. On the basis of the existing information and communication systems it is necessary to carry out: continuous or periodic assessment of a condition of objects of supervision and control; continuous (operational) collection, reception, transmission, processing, analysis and display of information resources. It is proposed to use UAVs (unmanned aerial vehicles) as a means to perform ASM tasks. The time of organizing communication sessions and delivery of information should vary from a few seconds to 2.5 hours. Untimely processing and delivery of a specific information resource in the management process leads to its obsolescence or loss of relevance, which contributes to erroneous decisions. One way to reduce time is to encode the data. To do this, it is proposed to use video compression algorithms. However, based on the analysis of the possibility of modern methods of video information compression, taking into account the specifics of the onboard equipment of the UAV, the coding problem is not completely solved. The research results show the expediency of using an improved method of video information compression to reduce the computing resources of the software and hardware complex of the onboard UAV equipment and to ensure the requirements for efficiency and reliability of data in modern threats to ASM systems as a whole.

“…In a separate arrays representation of the upperlevel, elements of the array are represented as twodimensional position numbers in difference space. In this case, the array code (1) k will be determined in relation to the code number that corresponds to the minimum level (2) V of the separate space. In connection with this, it is proposed to take into account the minimum values in each array's row of the upper quantized level in the process of forming the minimum level of separation space.…”

Due to the importance of the resulting image's content, it is necessary to minimize the time for the processing and bringing the given aerial photo in conditions of maintaining the necessary level of the restored image's correspondence to the original [2]. In the process of aerial photography, in various specialized devices, the mathematical description of the image is used as a twodimensional signal, which is characterized by some volume of information [3].…”

Ab s t r a c t. It has been considered the existing methods of processing of video information resource in modern aircraft navigation systems and motion control. Also it is indicated that there is a contradiction between the need to reduce the intensity of information resource for strongly saturated fragments and to maintain the correspondence of recovered fragments to the original aerial photo. It has been described the components' characteristics of the transforming for the image's areas with varying structure complexity. The rationalization of the dividing strategy is based on the complexity of aerial photographs is substantiated. It is proposed to quantize the transformation's description of an aerial video information segment in relation to the base element's value vector to a certain threshold value. The reduction of combinatorial redundancy as a result of the application of top-level quantized levels array in a separable space is substantiated.

“…It has been analyzed the predicted frames processing in the MPEG standard and its drawbacks has found during compressing video data. A method for encoding P-frames with the ability to select the type of blocks processing has been developed, where the structural redundancy estimation of the block is used as a decision rule [1][2][3]. Thus, it has been introduced an additional possibility to control the video bit rate by changing the number of I-and P-type blocks.…”
