Abstract

With the development of satellite networks, new generation of low earth orbit (LEO) satellite constellation network composed of mega satellites has emerged. The ground stations (GS) deployment has the key impact on the system throughput for LEO satellite constellation network. However, the GS deployment planning is challenging due to the spatial and temporal distribution of traffic demands and the time-varying topology of the LEO satellites. To solve this problem, an iterative GS deployment based on marginal revenue maximization (IGSD-MRM) is proposed. The key idea is to select the geographical location, which can achieve the maximum marginal revenue, as current GS deployment location in each iteration. The simulation results show the effectiveness of the proposed IGSD-MRM algorithm in throughput improvement under different GSs numbers and feeder link antennas.
