the subject of research in this article is a satellite system for remote sensing of the Earth, for which it is necessary to calculate the optimal traffic flow through the satellite –Earth station and satellite–satellite communication channels, which would require a minimum amount of bandwidth of these channels. This study is of great interest, since such systems in the modern world are used in most spheres of human life. It follows from this that finding the optimal parameters for the satellite–Earth station and satellite-satellite communication channels affects the efficiency of the system, and therefore the completeness and quality of the information transmitted from satellites to Earth. Some scheme is considered, which is an example of a satellite system for which a mathematical model was compiled using the contour method. The mathematical model was developed based on the assumptions of a deterministic information flow, which made it possible to reduce the formulation of the problem to a linear objective function and constraints. Thanks to the obtained model, a sample of possible flow values and bandwidth of communication channels was obtained, taking into account the limitation of their sum, when setting flow values on the satellite – Earth station channels.
