NTN GEO
Geostationary Orbit Satellite 5G
Non-terrestrial deployment operating at 35786 km altitude providing stationary regional coverage with high latency.
Technical Explanation
GEO satellites remain stationary relative to the Earth's surface at 35,786 km altitude, providing permanent coverage over entire continents with zero Doppler shift from satellite motion. However, round-trip propagation latency is approximately 540 ms, requiring 3GPP HARQ disabling or extension.
Key Functions
- Stationary orbit at 35,786 km altitude covering vast continental footprints
- Zero Doppler shift between satellite platform and ground terminals
- Round-trip propagation delay of ~540 ms managed via HARQ disabling
Specifications
3GPP TS 38.300, TR 38.821
