The group scheduling method for the tasks of imaging satellite network

The collaborative work of the multi imaging satellites can deal with the complicated tasks of users. On the one hand, some departments have the special task execution characteristics and they want to make task scheduling alone. On the other hand, some important departments or have their own resources, or have their own planning resources after applying and approval. This paper discusses the group scheduling of the shared satellite resources: Firstly, analyses the requirement of group scheduling and exhibit the framework of group scheduling; Secondly, building the model of group scheduling to perform the task scheduling of shared satellite resources; Thirdly, inspiring by the good convergence of ant algorithm and the good description ability of gene algorithm, this paper presents the improved gene algorithm by combining high order knowledge and low order knowledge, to solve the model. Finally, simulation experiments validate the effectiveness of task scheduling model and algorithm.
