Problems solved by technology

[0003]Currently, with the increase of the constellation scale, the number of satellites within the visible range of the gateway station will increase significantly, and the number of communication antennas will also need to increase accordingly. The area occupied by the gateway will also increase significantly, which will bring great difficulties to the site selection of the gateway station. Therefore, a new satellite tracking technology solution for the gateway station is needed

Abstract

The invention provides a satellite tracking device and method for a gateway station, the gateway station and a storage medium, and the device comprises: an antenna control module which is used for generating a control instruction, wherein the control instruction comprises antenna array surface dynamic configuration information; and phased array communication antenna equipment which comprises a plurality of antenna sub-arrays, and is used for combining the plurality of antenna sub-arrays into at least one phased array logic sub-array according to the control instruction, controlling the phased array logic sub-array to generate a single beam or multiple beams, and tracking at least one satellite. According to the device, the method, the gateway station and the storage medium disclosed by the invention, multi-beam access can be realized on a single phased-array antenna, so that the single antenna can communicate with multiple satellites at the same time, the occupied area of a communication antenna of the gateway station is greatly reduced, more beams can be formed on an effective area, the efficiency of a spherical array is greatly improved, and reliable tracking of the satellite can be realized.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite tracking device and method for a gateway station, a gateway station and a storage medium. Background technique [0002] Compared with geosynchronous satellites, low-orbit broadband satellites have the characteristics of fast satellite movement, short overhead service time of single satellites, and frequent switching of satellites and beams. The user terminal must use the narrow user beam to quickly capture and lock the satellite signal in a short time when the satellite is over the top, so as to increase the effective communication time as much as possible. The low-orbit broadband satellite communication system usually consists of a constellation of small communication satellites, and a ground gateway station composed of communication antennas to provide broadband communication services for ground users. The gateway station is usually composed of mult...
