Abstract
As we all know, satellite communication has the advantages of wide coverage, large communication capacity, etc. compared to terrestrial communication, and is not easily affected by geographical natural disasters. But the coverage of one satellite is limited, so we often need a constellation satellite communication system composed of multiple satellites to communicate. Also, the cost of satellites is relatively high, and the satellite constellation usually needs to consider both cost and communication performance, how to use the least cost to achieve a best communication performance. We construct a design multi-objective optimization model of satellite constellation for a local high capacity, using the improved NSGA-II algorithm to solve model, using STK software to simulate the results of the solution.
