Performance Analyses of Satellite Cluster System in Mega-Constellations

In the pursuit of ubiquitous connectivity, there is a growing interest in satellite systems owing to their large coverage. The deployment of a substantial number of satellites in low Earth orbits necessitates performance analyses and techniques to mitigate inter-satellite interference. Leveraging achievements in stochastic geometry, this paper proposes mathematical analyses for coverage performance by incorporating the concept of a satellite cluster, enabling joint transmission to address the challenges posed by mega-constellations. Furthermore, we investigate the influence of parameters such as cluster region on coverage performance. Validations of derived mathematical results are conducted through comparative analysis with simulation results. Our analyses can facilitate the efficient design of dependable satellite cluster systems by assessing the influence of design parameters on coverage performance.
