Virtualized Ground Stations: DIFI IEEE-ISTO 4900-2021 Digital IF Standard Compliance

Decoupling physical antenna dishes from software-defined software modems running in cloud data centers.

技術基盤とシステム制約

Deploying virtualized ground stations (vgs) 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.

実装アーキテクチャとプロトコルフロー

The protocol workflow for virtualized ground stations (vgs) 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.
