Embodiment Construction

[0024] See attached figure 1 , attached figure 2 , and attached image 3 The present invention is further described.

[0025] A satellite antenna automatic star alignment method is characterized in that, the satellite antenna automatic star alignment is carried out according to the following steps:

[0026] Step S1) Coarse star alignment, start the automatic star alignment function, calculate the theoretical values ​​of the azimuth angle, elevation angle and polarization angle of the satellite antenna according to the longitude and latitude of the satellite and antenna, the radius of the earth, and the distance from the satellite to the ground, and set The pointing of the satellite antenna is adjusted to the theoretical position;

[0027] Step S2) Fine alignment, after completing the coarse alignment process involved in step S1), control the antenna to perform traversal scans within the specified range along the directions of azimuth, elevation, and polarization, with the ...

Abstract

The invention relates to an automatic aligning method for a satellite antenna. The automatic aligning method is characterized in that the aligning method comprises the following processes: coarse alignment, precision alignment, antenna pointing deviation monitoring and automatic satellite tracking, wherein the automatic satellite tracking process comprises quick satellite tracking and stable satellite tracking. According to the automatic aligning method for the satellite antenna, the steps of quick tracking and stable satellite tracking are additionally added in the conventional satellite antenna aligning method, so that the antenna pointing can be corrected to the optimal position through realization of automatic satellite tracking under the situation that longitude and latitude of the satellite are changed due to the fact that a geostationary orbit satellite shifts periodically by following a 8-shaped path or relative antenna pointing deviation occurs due to physical cause.

Description

technical field [0001] The invention relates to the technical field of satellite antenna automatic control, in particular to an automatic satellite alignment method for a satellite antenna. Background technique [0002] At present, the satellite antenna automatic star alignment system used for geosynchronous orbit satellite communication usually adopts the following star alignment method: first, calculate the azimuth angle of the satellite antenna, Theoretical values ​​of pitch angle and polarization angle; then, adjust the pointing of the satellite antenna to the theoretical position; finally, make fine adjustments to the satellite antenna near the theoretical position until the received signal strength reaches the maximum value. [0003] The above satellite alignment method is usually effective when the latitude and longitude of the satellite and the attitude of the antenna remain unchanged. However, in practical applications, these two conditions are difficult to be stric...
