다중 궤도 위성 기반 하향 네트워크의 실증적 커버리지 분석

Although stochastic geometry-based modeling of LEO satellite networks has been actively studied, existing research has limitations such as assuming fixed user locations or not considering satellite unavailability. This study experimentally analyzes the coverage probability based on satellite availability in a multi-orbit model inspired by the OneWeb satellite constellation. We verify that the one-dimensional Poisson point process (PPP) model aligns well with actual satellite deployments and propose a modified coverage expression that accounts for satellite unavailability. Furthermore, simulations under various satellite density conditions are conducted, and we identify the optimal satellite density that ensures stable coverage even when the primary satellite becomes unavailable.
