Communication Constellation Design Trimmed by Network Routing

Abstract

Communication constellation design and satellite network routing are conventionally treated as two independent design processes; however, the routing results can actually give opinions to the constellation structure on its communication service quality. Based on this consideration, a new communication constellation design method is proposed in this paper which allows the constellation design to be trimmed by the routing in the way of introducing the routing result as a feedback, aiming to achieve a better constellation structure for the routing. The design method rationale is explained and a simulation scenario is given. With a basic Celestri configuration and opening the inclination to several options, the minimum link handovers and time delays offered by routing optimization on each configuration structure are compared. The simulation results show that by altering the Celestri inclination with a small amount, the constellation can achieve better routing performance, which validates the new design method.
