Abstract

The invention provides a construction method and device of a multi-beam relay satellite task scheduling model, and relates to the technical field of task scheduling. When the model is constructed, for tasks of multiple beams and multiple directions of a space-based backbone network relay satellite system, constraint conditions of visible time windows, task attributes, limited resources and the like are comprehensively considered in a scene with multiple beams; therefore, a task scheduling scheme obtained based on the model can complete the planning of the relay satellite task under the condition of meeting the constraint conditions, the task with higher priority can be successfully scheduled as far as possible, and the task scheduling efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of task scheduling, in particular to a method and device for constructing a multi-beam relay satellite task scheduling model. Background technique [0002] With the continuous construction of the space-based backbone network, the number of user spacecraft that require relay satellite services continues to increase. Due to the limited number of relay satellites, data service capabilities are limited, and there is a visible time between user spacecraft that require relay satellite services Therefore, it is necessary to arrange and dispatch the task planning of the relay satellite reasonably to improve the utilization rate of the relay satellite, and then improve the efficiency of the entire spatial information network. [0003] The main object of the research on the task scheduling of the existing relay satellite system is the scheduled task. Due to the complexity of the task scheduling problem of the relay sa...
