Abstract: Top mission design is usually closely associated with satellite constellation. The decentralized and flexible features of small satellites match the use of largescale constellation in orbit. The application method of multivariate global optimization and intelligent optimization for constellation design was presented with consideration for the different mission requirements of hotspot coverage and global coverage. Therefore, the optimal performance of small constellation and the superior performance of largescale constellation could be obtained. These methods for satellite constellation optimization are not restricted by orbit types and mission target distributions, and show the good performance of robustness.

Key words: satellite constellation, multivariate, global optimization, intelligent optimization
