Abstract: The satellite data transmission task scheduling model is established,and the constraint conditions and the scheduling objective are discussed.The adaptive scale particle swarm optimization(ASPSO) is designed,which uses decimal coding based on satellite-facility workable time windows.The particle coding represents the probability of data transmission task which can be distributed in different satellite-facility workable time windows.In this method,the population size is adjusted based on a diversity of swarms,while deleting particles with the little diversity degree and adding new particles so as to maintain population diversity.By simulation,it shows that the ASPSO excel at result and convergence in solving the satellite data transmission scheduling problem,and the values of each control parameter of the ASPSO are analyzed.
