Abstract:In this paper, the relationship between the various inter-satellite link (ISL) parameters of multilayer satellite network is analyzed. The relationship among Eb/N0, transmit power, antenna diameter and data rate of GEO(geostationary earth orbit)/IGSO(inclined geosynchronous orbit ), GEO/MEO(middle earth orbit) and IGSO/MEO inter-satellite links are analyzed and calculated, and the performance of ISL is analyzed according to the calculation. From the result, some regularity conclusions are obtained, which can be used for design and establishment of ISL.

Key words: satellite network; satellite communication; inter-satellite link
