摘要
Space-air-ground integrated networks(SAGINs)address the limitations of terrestrial networks by integrating satellites in various orbits,aerial drones,and ground networks to enhance network coverage and reliability.This integration aims to ensure seamless communication across vast and remote areas,significantly expanding the reach of network services.Additionally,SAGINs are designed to support a high degree of network resilience and adaptability,facilitating advanced applications such as real-time data processing and global internet connectivity.
