Route analysis of satellite constellation based on directional crosslink with narrow-beam antenna

Abstract

Using directional crosslinks could help significantly improving the performance of satellite network because of the high safety, low power consumption, long communication range and little self-interference of the directional crosslink. The more in-depth study on satellite network with the directional crosslink, the more urgent to study the route of the network becomes. It is necessary to formulate scheduling of links with various constraints and facts before constellation operation and deployment for narrow-beam directional crosslink in the network. This article is based on a typical Walker model to analyze the routing of the network with directional crosslink, and proposes two route schemes. Finally, these two routing schemes are compared and summarized. © 2011 Springer-Verlag Berlin Heidelberg.
