Problems solved by technology

In actual operation, the bandwidth of the beacon signal is narrow, it is not easy to capture, it is easy to be interfered, and it has high requirements for the response of the system
In addition, the star-finding equipment often used for satellite communication is based on the star-finding method, and a beacon signal receiver is used. This kind of beacon signal receiver is relatively expensive, and the cost is several times that of the channel signal receiver.

Description

technical field [0001] The invention relates to an automatic star-seeking device for a satellite communication antenna, in particular to a wire-controlled star alignment device for a vehicle-mounted satellite communication antenna. Background technique [0002] At present, the method of receiving satellite beacon signals is usually used in the satellite communication star-seeking method, and the pitch angle, azimuth angle and polarization angle of the antenna are adjusted to achieve the best receiving positioning of the antenna. In actual operation, the bandwidth of the beacon signal is narrow, it is not easy to capture, it is easy to be interfered, and it has high requirements for the response of the system. In addition, the star-finding equipment used for satellite communication is often based on the star-finding method, and a beacon signal receiver is used. This kind of beacon signal receiver is relatively expensive, and the cost is several times that of the channel signa...
