Abstract

Problem statement: The formation of the dish system of the radio telescope antenna in the near-earth orbit can significantly improve its main characteristic, namely, the value of the aperture surface utilization factor (SUF). In this case, practically excluded its dependence on deformations of weight and wind effects. Purpose: Solving the problem of increasing the aperture efficiency (AE) of the space radio telescope by controlling the position of the reflecting shields of the dish system and the radiation receiver. Results: The method of formation in orbit with the satellites of the earth the dish system of the space telescope. The method of its adjustment and focusing with the help of controlled elements based on SEMS modules is developed. Practical significance: The automatic control system (ACS) is described, which allows forming, adjusting and focusing the dish system of the antenna of the space radio telescope. The ACS provides an increase AE of a space radio telescope with a significant variation in the operating frequency ranges of the received radiation and in the absence of the influence of the Earth’s astronomical climate.
