Research On Data Receiving And Scheduling Of Multi-Ground Station Remote Sensing Satellite

With the continuous development of China’s space industry and the opening of commercial satellites,the number of satellites launched has increased dramatically in recent years,this also means that a large number of ground-based systems are needed to support the data reception of these satellites,However,the current satellite data ground receiving system can not match the number of satellites.Therefore,in order to receive satellite data more efficiently and fully,it is necessary to establish a cooperative working mechanism of multiple ground stations.Reasonable dispatch and management are needed for receiving remote sensing satellite data from multi-ground stations.Based on this background,this paper focuses on the receiving and scheduling of multi-ground station remote sensing satellite data.The main work of this paper include the following parts:(1)This paper expounds the current research status in this field at home and abroad,analyzes and summarizes some unsolved problems,which provides a theoretical basis for the writing of this paper;(2)Summarizes the transmission process,constraints and task conflicts in the satellite data transmission task,analyzes the optimization algorithm theory of satellite data transmission task and scheduling in previous literature,Finally,under reasonable assumptions,obtain the key objectives of the optimization problem,and according to these targets,the problem model of multi ground station remote sensing satellite data receiving and scheduling is established;(3)Use the optimization genetic algorithm to calculate the problem model established,and effectively improve the efficiency of all aspects;(4)Imitate experiments to analyze the problems under different resource conditions,task distribution conditions and problem model,the final experimental results proved that the algorithm used in this paper is effective in solving this problem.
