Problems solved by technology

[0005] (1) When the antenna base or the antenna surface deviates, there is no automatic tracking function, and the antenna system can only rely on manual activation of the star alignment program to re-align the satellite. It is difficult to ensure that the antenna is aligned with the satellite at all times, resulting in low star alignment efficiency
[0006] (2) When the base of the antenna is not shifted, and the received signal level drops only due to external factors such as temporary occlusion and rain, re-aligning the satellite will lead to mistracking

Abstract

The invention provides a system and method for controlling a satellite finding antenna. The system comprises an antenna feeder subsystem for receiving a beacon signal of a target satellite, a satellite communication subsystem for converting the beacon signal to the beacon signal of L wave band, a servo control subsystem for determining the angle adjustment information of the antenna according to the current angle information of the position of the target satellite and the antenna during first alignment of the antenna and determining the angle adjustment information of the antenna according to the converted beacon signal when judging that the angle of the antenna is changed, and an antenna driving subsystem for driving the antenna to direct the target satellite according to the angle adjustment information. In the invention, the angle adjustment information of the antenna is determined according to the beacon signal of the target satellite during angle change after antenna alignment so as to drive the antenna to be aligned to the target satellite according to the angle adjustment information to realize the automatic satellitet of alignment program, ensure that the antenna is capable of being aligned to the satellite at any moment and improve the working efficiency.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a control system and method for a star-seeking antenna. Background technique [0002] At present, satellite antennas mainly include small-caliber manually adjustable fixed-station antennas, large-caliber electric-driven fixed-station antennas, vehicle-mounted stationary antennas and portable antennas. Among them, the small-caliber manual adjustment of the fixed station antenna has a simple mechanical structure, and requires technicians to complete the star alignment, antenna adjustment, and star pair installation and maintenance by adjusting the three-axis mechanical device of azimuth, elevation, and polarization with the assistance of the spectrum analyzer. The professional technical level of personnel is required to be high. Due to the large diameter of the large-caliber electric-driven fixed station antenna, it is necessary to use a motor to drive the azimuth, pitch and...
