Low-Orbit Large-Scale Communication Satellite Constellation Configuration Performance Assessment

A constellation configuration performance evaluation method is proposed for the of low-orbit large-scale communication satellite constellations. The practicality and feasibility analysis mainly studied from coverage performance. Based on consideration LEO constellation, four simulation models are established single rate, observation elevation angle, number visible satellites under different angles, efficiency constellation. population distribution density function according to characteristics find average minimum angle distribution. applied three typical constellations, Telesat, OneWeb, Starlink, derive index values each compare analyze results show that can evaluate types constellations provide a basis reference optimal design future configurations.
