Automatic satellite alignment method and apparatus, and satellite

Abstract

The invention relates to an automatic satellite alignment method and apparatus, and a satellite. The method comprises the following steps: receiving satellite identification input by a user, and according to the satellite identification, querying satellite position information corresponding to the satellite identification in a preset configuration list; according to the satellite position information, adjusting an antenna position for performing satellite alignment; in a satellite alignment process, according to a preset period, continuously sending satellite alignment signals to a satellite at a satellite position so as to enable the satellite to determine whether the satellite alignment succeeds according to the satellite alignment signals, wherein the satellite alignment signals carry a satellite alignment completion instruction and satellite identification information; and if response information of satellite alignment success, returned by the satellite is received within preset time, executing satellite locking motion. According to the invention, the situation of alignment with a false satellite can be avoided, atmosphere interference is not easily caused, and the automatic satellite alignment accuracy is improved.

Description

technical field [0001] The invention belongs to the field of satellite communication, and in particular relates to an automatic satellite alignment method, device and satellite. Background technique [0002] Beacon machine: It is an important part of the satellite antenna servo tracking system. Its main function is to mediate and process the satellite beacon signals of the C, Ku, and Ka bands that are down-converted to the L-band, and adjust them for the servo system. AGC voltage and lock indicator level, so that the antenna can be accurately aimed at the satellite to achieve dual communication. [0003] At present, the satellite communication earth station mainly realizes the function of automatic star alignment by detecting the communication signal strength through the beacon machine. When the signal strength is greater than the preset threshold, it is determined that the satellite antenna is aligned with the satellite; otherwise, continue to adjust the antenna position. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide an automatic star alignment method, device and satellite, aiming to solve the problem of easy alignment to "false stars" and easy atmospheric interference when performing star alignment operations through beacon machines in the prior art. In an environment with low signal strength, it is impossible to achieve star-to-star operation and the beacon machine is large in size and expensive, which is not conducive to the problem of star-seeking for portable antennas and small-aperture antennas.
