The growing interest in space-based broadband internet, propelled by the rapid expansion of mega-constellations, amplifies the mounting concerns about interference and spectral coexistence for both operators and users. Given the complexity of these systems, deriving reliable estimates for data rates and interference typically requires labor-intensive simulations. However, recent advancements have introduced analytical methods rooted in stochastic geometry to assess system performances. Building on these insights, our work aims to precisely evaluate interference in these systems, focusing on adjacent satellite interference and multi-beam inter-cell interference. Significantly, we introduce a more refined estimation of these effects based on the nature of highly directive antennas, an aspect missing in current literature. We, therefore, propose numerical approximations for these key values detrimental to high-speed telecommunication systems. We present simulation results to validate our analytical approach and share numerical findings from our proposal to offer deeper insight into mega-constellation systems and designs.
