Issues in development of self-pointing on information signal antenna systems

Development of information systems, space navigation systems (GPS, NavStar, etc.) and active development of space industry requires further improvement of ground stations designed for space vehicles operation support. At present the tasks of transmission of huge information flows gain more importance due to improvement of earth satellites control systems. It requires solution of problem concerning combination of functions of information reception and satellite command control. It is necessary, for example, in development of self-pointing antenna systems of ground stations for space vehicles control. Presented in this paper is multistage structure of sum-difference processing.
