Abstract

The invention discloses a dynamic elastic satellite beam scheduling method, and the method comprises the steps: receiving task information inputted by a user, obtaining ephemeris information of a satellite, and processing the task information according to the ephemeris information to obtain a first task model and a resource model in three dimensions of time, space and frequency; and performing satellite beam scheduling on a preset dynamic elastic adjustment scheduling window length according to a preset triggering mechanism, the first task model and the resource model. The technical problem of low overall use efficiency of satellite beam scheduling in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of satellite communication, in particular to a dynamic and elastic satellite beam scheduling method. Background technique [0002] The use of satellite beam scheduling technology can improve the satisfaction rate of user needs and the use efficiency of satellite beams. Among them, the efficiency of the use of satellite beams is reflected in the three dimensions of time, space, and frequency (hereinafter replaced by "time-space-frequency three-dimensional"). For the future high, medium and low fusion space-based information network system, the satellite beam has more dynamics and complexity in three dimensions of time, space and frequency. [0003] At present, the satellite beam scheduling technology at home and abroad is mainly used in the field of beam scheduling of relay satellites in high-orbit geosynchronous orbits, and the reservation-type satellite beam scheduling technology is mainly used. ...
