Abstract

The invention provides a relay satellite system beam scheduling system and method for multiple types of service requirements. The system comprises a beam feature generation module, a service feature acquisition module, a heterogeneous beam scheduling model construction module, a variable acquisition module, a service beam matching module, a beam scheduling module and a service scheduling sequence optimization module. The beam feature generation module comprises a plurality of antennas with different frequency bands and different types, and a control mechanism of the plurality of antennas; the beam feature generation module is used for generating beam forming required by services and executing beam switching when the services are provided for different users; and the optimized beam scheduling scheme output by the beam scheduling module is provided for the beam feature generation module for executing the service required by the user.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a beam scheduling method for a relay satellite system oriented to multi-type business requirements. Background technique [0002] Chinese Patent Publication CN103944622A discloses a beam control method for an S-band phased array relay transmitting antenna, the goal of which is to solve the beam pointing control problem of the S-band phased array transmitting antenna. [0003] U.S. Patent Publication US20200382203A1 discloses precise beamforming based on user equipment location, which proposes various configurations for optimizing data transmission between satellites and user equipment. The satellite gateway system may receive a message from the user equipment indicating the current location of the user equipment. Data can be retrieved from the Internet for transmission to user equipment via satellite. The satellite gateway system may send downlink me...
