Abstract: For the case of the developing difficulty, long cycle and high cost of crosslink system, a whole system simulation architecture of crosslink was designed and realized. Based on simulation structure steps of ‘system’ plus ‘signal’, selection of constellation configuration and topology was discussed. The paper focused on the visibility analysis and crosslink optimizing, and made detailed analysis of crosslink signal′s measurement error. The analysis and simulation proposed are easy to implement, and can provide thorough analysis for the engineer, hoping to increase the research efficiency.

Key words: Inter-satellite link, Visibility analysis, Crosslink optimizing, Simulation analysis
