Review of task scheduling research for the Earth observing satellites

Satellite task scheduling is one of the kernel modules of the satellite system, and its performance is directly related with the performance of the whole satellite system. The research status of several key problems is summarized and the future valuable research directions are proposed. Firstly, the intelligent technologies of dealing task requirement are analyzed, and the process of intelligent assistant analysis is casted. Secondly, the task decomposing of region target and the task clustering of point target are described. Thirdly, the research approaches of satellite task planning and scheduling model and solving algorithm are summarized, for single satellite and multi-satellites, respectively. Finally, the bottleneck problems are analyzed, and the research directions of satellite task scheduling and the suggestion of future work are given.
