The article aims to improve the state agribusiness regulatory system. It is established that the state regulatory system for agribusiness must be based on the application of a reasonable protectionism policy, guaranteeing food security through a system of tariffs and customs taxes on imported food products. The authors demonstrate the need to create a favorable climate for foreign investors, establish joint ventures in the agricultural business, provide state guarantees to foreign creditors by importing advanced equipment and technology, as well as finance key areas of science on business problems. Agricultural, the theoretical and methodological basis of this study is an abstract logical method, induction, deduction, analysis, synthesis and systematization methods; as well as the statistical, economic and graphic methods used to study the levels and trends of change in the parameters of agricultural development in the current stage. In conclusion, it is revealed that parities in agricultural prices must include parity with consumer prices. For rural residents. The wages of employees in rural areas must guarantee the reproduction of the labor force and the development of the social sphere.

The article analyzes the production and sale of grain in agricultural enterprises of the Kursk region. Changes in the size and structure of crops are revealed, the dynamics of production and sales of the main types of grain crops for 2011-2019 are analyzed both in physical weight and in value terms. It was found that during the study period, the dynamics of production and sale of grain crops in the Kursk region have a generally positive trend. The valuation of the dynamics of sales of products of the main types of grain crops demonstrates steady growth due to the rise in prices for products. The article presents trend models that allow assessing the dynamics and forecasting the development of grain production and sales in the Kursk region. It was revealed that among all grain crops the maximum growth in sales volumes is steadily demonstrated by wheat. The function obtained from the results of trend modeling with a high degree of reliability indicates the actual growth and allows us to predict an increase in sales of wheat for the region. It is concluded that the factors that influenced the changes and identified the prospects for growth in the production of certain types of crops.

Relevance. Known models, algorithms and technical solutions for determining the coordinates of aircraft are partially suitable for determining the location of small spacecraft, since the latter do not have their own means of determining and transmitting coordinates. This limitation does not allow continuous control of a small spacecraft and reduces its functionality. It is proposed to use the actively developing system of automatic dependent surveillance-broadcasting, installed on aircraft and allowing transmission of their coordinates, including to small spacecraft. Such aircraft are considered to be a kind of mobile reference objects in the airspace of the Earth. The study poses and solves a modified triangulation problem – determining the coordinates of a small spacecraft by the coordinates of reference moving objects (aircraft). Purpose. Development of a block diagram of a module that calculates the coordinates of a mobile spacecraft using a mathematical model for processing signals received from reference aircraft transmitting their own coordinates. Methods. Within the framework of the article, the main physical (Doppler effect) and geometric relationships of message transmission between receivers and transmitters and hardware and software solutions are considered, designed to obtain the processing of coordinates of message transmitters on board a small spacecraft. The results obtained make it possible to determine the location of the small spacecraft. The general block diagram of the coordinate determination module has a parallel organization and can be used in high-performance computing systems. On the basis of a mathematical model, an algorithm for determining the area of finding the apparatus and a block diagram of the coordinate processing module are obtained, characterized by the presence of a specialized parallel search unit. Modeling the algorithm on the reference data has shown the required accuracy in determining the area of the vehicle as a result of solving the modified problem. The obtained values of the variance of the computational domain indicate the efficiency of this approach and justify the hardware solution of the problem of determining the coordinates of a small spacecraft. Conclusion. The block diagram of the module for determining the position of the small spacecraft based on the ADS-B signals is the most compact and energetically less expensive solution than the GPS, which allows calculating the coordinates of the small spacecraft using a receiver, the consumption of the battery is only for receiving and processing data. In contrast to the presented scheme for receiving-processing and calculating the coordinates of the small spacecraft, existing similar solutions in a number of nanosatellites of the CubeSat standard are used, in addition to the processing algorithm and the receiving path, also transmitting equipment, which is many times more energy-intensive than the equipment presented in the form of a structural diagram of the position determination module ICA, in this article.
