    Abstract
  • The special features of low earth orbit (LEO) communication constellation determine that costs, coverage and routing performance should be wholly taken into account in configuration optimization. In previous cases, the optimized configuration cannot meet the requirements well as routing performance was often ignored.Two evaluation indicators with clear meaning were proposed to signify routing performance and their necessities and effectiveness were proved in their simulation as objective functions. After that, the application of routing algorithm in configuration design was realized. According to the results comparison, in the premise that the configuration has little change, not only the basic requirements of costs and coverage are fulfilled, and also the routing performance of constellation is greatly improved when routing algorithm is added into configuration optimization. The best configuration design is obtained and some useful conclusions are showed finally.
