Abstract
With the development of satellite laser communication technology, data-relay satellite system using optical links will become the backbone of space-based information system in the future. At first, a network architecture of 2 territorial stars +2 overseas stars was designed, then the optical satellite network performance indexes were defined based on the analysis method of SPC exchange(stored program control exchange), and lastly the performance of data-relay satellite system using optical links was simulated. The simulation results show that data-relay satellite system using 12 optical links can support 50 user satellites, when each user satellite communication traffic is 0.2 Erl, access loss probability is greater than 0.2, and link utilization is greater than 0.6.
