Abstract

The invention discloses a method and a device for seeking stars by using a satellite antenna. The method comprises the steps of: S1, judging that the antenna is in an unfolded state or a folded state; S2, if the antenna is in the folded state, controlling a main reflecting surface of a pitching motor driving antenna and a feed source supporting rod to be lifted to the preset positions by using a control system, installing side lobes and carrying out the step S3; if the antenna is in the unfolded state, directly carrying out the step S3; S3, reading the data of an inclinometer and calculating the pitching state of the antenna according to the data by using the control system; S4, initializing the direction state of the antenna by using the control system; S5, rotating the main reflecting surface of the antenna to the working position by using the control system; and S6, carrying out satellite search and step tracking by using the control system. The invention achieves the purpose of accurate star seeking by adopting the control system for control the polarization, the direction and the pitching of the satellite antenna and solves the problems of complicated operation, instable performance and low star-matching speed of the satellite antenna in the prior art.

Description

technical field [0001] The invention relates to the technical field of satellite antenna control, in particular to a method and system for satellite antenna satellite finding. Background technique [0002] At present, the small satellite antennas used in the field of satellite communication generally use manual methods to align the satellites. The operator manually rotates the azimuth, elevation and polarization of the antenna, and observes the satellite signals with instruments until the satellite signal is the largest, and then aligns with the satellite. In the actual use of this antenna, its star-to-star mode shows complex operation, long star-to-star time, and the need for professionals and special instruments. Contents of the invention [0003] (1) Technical problems to be solved [0004] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is how to improve the speed and reliability of star alignment an...
