In order to achieve long-distance measurement and control of deep space detectors, increasing the aperture is the most direct means to improve antenna performance. However, the increase in antenna size brings structural instability and is easily affected by external environments such as temperature, gravity, and wind gusts. Aiming at the problem that temperature changes affect the antenna pointing accuracy, this paper designs and implements an antenna pointing temperature compensation model, and conducts data collection and test verification. The results show that the antenna pointing accuracy can be compensated effectively under a large temperature environment by the method proposed in this paper, and the received signal strength is improved.
