Abstract

A satellite tracking method, which is used for the fast tracking and alignment of satellites, comprising: acquiring a directional coefficient function of an antenna (S100); acquiring a Jacobian matrix of the directional coefficient function, the Jacobian matrix being used for determining a direction of angle compensation for the antenna (S200); acquiring a deviation angle matrix of the antenna relative to a satellite by means of scanning, the deviation angle matrix being used for providing a function model in order to acquire a compensation angle (S300); acquiring the compensation angle according to the directional coefficient function, the deviation angle matrix and the Jacobian matrix, the compensation angle being used for guiding the antenna to move at a next moment; dynamically acquiring the compensation angle and continuously adjusting the antenna according to the compensation angle during a process of alignment so as to scan, track and align the satellite (S500). A satellite tracking error is rapidly converged by means of acquiring less or lower-frequency beam signal data, thus implementing high-precision satellite alignment.

Description

technical field [0001] The invention relates to the field of electromagnetic beam tracking, in particular to a satellite tracking method. Background technique [0002] Accurate capture and tracking of satellite signals has always been a core indicator of satellite antennas. Most of the current automatic satellite tracking methods involve hardware analysis of the power level value rssi of satellite signals for beam signal indication. The current satellite tracking algorithm is a simple processing of the signal value of the satellite beam, by stepping and scanning near the incoming beam, searching for the maximum point of the signal, as the basis for star alignment, the signal processing method is very simple. There is a large time delay, the error is also large, and the accuracy needs to be improved. [0003] Moreover, part of the scanning method is only based on finding the position of the maximum received signal. This processing mechanism has no problem for unilateral rece...
