Abstract: To study protocols and algorithms for Low Earth Orbit(LEO) satellite networks, a platform is built based on OPNET. The platform introduces the key points including topology design, node models, process models, link models and etc. It can simulate the procedures of routing table generation and packets routing in LEO satellite networks. Since satellite networks run regularly in the space, topology snapshot based static routing strategy is adopted, packets routing is simulated in an example satellite network, and the validity of the platform is proved.

Key words: satellite network, OPNET, simulation
