Abstract: In recent years, the ground-based observation experiment of lunar irradiance has been increasing. In order to meet the high-precision and high-frequency observation of the lunar radiation on the ground, it is necessary to design a high-precision lunar automatic tracking system for tracking experiments. The designed tracking system uses the lunar position algorithm to obtain the zenith angle and azimuth of the moon for apparent motion tracking, and then uses the photoelectric tracking with the four-quadrant detector as the core device to accurately track the moon. After the external field tracking experiments, the combination of apparent motion tracking and photoelectric tracking has high-precision tracking effect. The tracking accuracy is within ±0.2°, indicating that the tracking system has high accuracy and reliability.
