Satellite Core Gateway
Inter-Orbit Intersatellite Routing Gateway
The specialized core interface linking ground core networks with autonomous routing fabrics operating on LEO satellite constellations.
Technical Explanation
Connecting terrestrial ground networks with satellite constellations requires handling dynamic routing topologies and high-speed Doppler shifts. The Satellite Core Gateway terminates optical ground-to-space laser feeders and RF Ka/V-band feeder links. It translates terrestrial 3GPP protocols into delay-tolerant space routing protocols, managing user session continuity as satellites orbit into and out of ground station sightlines every 10 minutes.
Key Functions
- Terminating high-capacity optical laser and RF feeder links connecting space and ground
- Translating terrestrial 3GPP protocols into Delay-Tolerant Networking (DTN) space protocols
- Managing ground station handovers as overhead LEO satellites traverse sightlines every 10 minutes
- Dynamic routing traffic into inter-satellite optical laser cross-links (OISL) in orbit
- Autonomous buffering maintaining session state during temporary weather feeder link fades
