A: Terrestrial systems act as ground-based infrastructure to support satellite communication by managing signal routing, data processing, and connectivity to end-users. They bridge satellite networks with local networks like the internet or cellular systems. This ensures seamless integration between space and ground segments.
A: Satellites provide wide-area coverage, especially in remote regions, while terrestrial systems offer high-speed, low-latency connectivity in urban areas. Together, they enable hybrid networks for global connectivity. This combination improves reliability and reduces coverage gaps.
A: Integration enhances network resilience by providing backup during terrestrial failures or disasters. It also improves bandwidth efficiency by offloading traffic between systems. Additionally, it supports applications like IoT and 5G through unified connectivity solutions.
A: Key challenges include managing signal latency differences between satellites and ground networks. Spectrum allocation conflicts and interference mitigation also pose issues. Standardizing protocols across both systems requires complex coordination.
A: Innovations focus on 5G integration and low Earth orbit (LEO) satellite compatibility. Advanced beamforming and edge computing are optimizing ground station performance. Efforts also prioritize dynamic spectrum sharing to reduce congestion in hybrid networks.
