Title:
SATELLITE TRACKING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/071917
Kind Code:
A1
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.
