Abstract: The analysis and optimization of constellation's coverage in the opinion of simulation are introduced.The questions,which should be solved in the process of simulation analysis,are discussed firstly.Then the algorithm of global coverage decision and point coverage decision at one sample time are presented.Some parameters to analyze simulation results are given,and these parameters are integrated into Constellation Coverage Performance by the use of fuzzy analysis.Based on the research,the nonlinear optimization of constellation's global continuous coverage is discussed.
