Space-Ground Integrated Networks (SGIN) & Unified 5G Core Architecture

Architectural blueprints for connecting thousands of LEO satellites with ground teleports, UPF offload at the orbital edge, SBA (Service-Based Architecture) microservices for space nodes, and unified subscriber identity provisioning via standard SIM/eSIM credentials.

Technical Foundations & System Constraints

Deploying space-ground network orchestration in non-terrestrial environments requires solving fundamental physics constraints: path loss over 1000km distances, rapid carrier frequency shifts due to Doppler effects, and power-thermal limits of spaceborne hardware. The architecture provides deterministic mitigation strategies.

Implementation Architecture & Protocol Workflows

The protocol workflow for space-ground network orchestration coordinates physical layer signal acquisition with higher-layer transport resilience. By leveraging open-loop ephemeris calculations and adaptive retransmission timers, communication links maintain uninterrupted throughput across satellite handoffs.
