By abstracting the relevant elements of the mission planning problems of space astronomical satellite and establishing the mathematical model of mission planning of the space astronomical satellite, we introduce the Genetic Algorithm and design the single-objective Genetic Algorithm based on the communication mission window. In addition, based on the Genetic Algorithm, a multi-objective Genetic Algorithm based on the sequence of communication window is designed, which improves the coding ability of Genetic Algorithm and improves the flexibility and applicability of planning effect.Problem analysis Use new mathematical Problem assumptions modeling of multi-objective and simplification optimization Mathematical Increase the dimension of the modeling of simple objective function to get new objective mission model lanning Determine the Use communication objective function opportunity window sequence to encode Design fitness function set Determine encoding based on objective function method set Design new genetic Detennine fitness operators based on NSGA function [ j Design genetic Design the multi-objective operators genetic algorithm flow Design the genetic Run simulation and obtain algorithm flow optimal mission plan Run simulationand Execute data transmission obtainoptimal mission according to the mission plan plan Figure 1
