【Abstract】 To shorten the computation time of optimal regional coverage constellation, an improved method of grid simulation was put forward in this paper. Analytic method was used to calculate the coverage performance during the statistical period, and the genetic algorithm was applied for optimal design of satellite constellation. The simulation result showed that the processing time of new method was one hundredth of the old one.更多还原
