Selection method for route planning of satellite-to-ground integration and selection apparatus thereof

Abstract

The embodiment of the invention provides a selection method for route planning of satellite-ground integration and a selection apparatus thereof. The selection method comprises the following steps that: all satellite-to-ground route plans of a satellite-to-ground transmission phase is determined according to a task sequence and sampling is carried out on all the satellite-to-ground route plans to obtain some initial satellite-to-ground route plans; on the basis of each of the initial satellite-to-ground route plan, at least one neighborhood satellite-to-ground route plan corresponded to each of the initial satellite-to-ground route plan is constructed; an optimal satellite-to-ground route plan is selected from each of the initial satellite-to-ground route plan and the at least one neighborhood satellite-to-ground route plan corresponded to the initial satellite-to-ground route plan; according to all the optimal satellite-to-ground route plans, an optimal ground route plan of ground network transmission phases corresponded to all the optimal satellite-to-ground route plans is obtained, thereby forming some selectable general route plans; and according to an overall performance of all the selectable general route plans, an optimal general route plans is determined from some of the selectable general route plans. According to the invention, time expenditure and space expenditure for calculation are substantially reduced; and integrated task planning is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of satellite communication, and in particular to a satellite-terrestrial integrated route planning and selection method and device. Background technique [0002] With the rapid development of satellite communications and related technologies in recent years, a satellite-ground integrated network composed of satellites and ground station systems from various countries has gradually formed. According to the characteristics of the satellite mission, the transmission process can be divided into the satellite-ground transmission stage and the ground network transmission stage. [0003] In the scheduling and planning of satellite communication tasks, most of the researches at home and abroad separate the two stages, and only deal with a certain part of them separately. According to the optimized scheduling scheme obtained during the satellite-to-ground transmission stage, after the task ...

AI Technical Summary

Problems solved by technology

[0004] The few studies on integrated transmission currently exist, in order to get the optimal planning scheme, it will take a lot of time for calculation, and a huge storage space requirement will be generated during the calculation process

As the number of satellite tasks to be scheduled gradually increases, the cost of time and space will increase sharply, so it is not suitable for scheduling large tasks
