Optimal Beam Management in Earth-fixed Satellite Systems

Abstract

In this paper we investigate the beam management issue for providing optimal mapping between ground and space terminals in earth-fixed satellite systems. We take the non-homogeneity of the traffic demands into account and define an optimal beam management problem for supplying more bandwidth to denser areas. We model the problem as a network flow problem and propose a feasible solution approach. Performance results show that significant improvement in system availability can be achieved at the expense of acceptable increase in the system cost.
