NTN Transparent Payload
Bent-Pipe Satellite Architecture
Satellite architecture functioning as an RF transponder ('bent-pipe') relaying 5G NR signals to ground gNodeBs.
Technical Explanation
In transparent payload mode, the satellite contains only RF transponders and frequency converters (no baseband processing). The satellite acts as an airborne mirror, receiving 5G signals from UEs and relaying them down via a feeder link to a standard terrestrial gNodeB gateway on Earth.
Key Functions
- Functions as an RF bent-pipe transponder without onboard baseband processing
- Relays 5G radio signals directly to terrestrial ground station gNodeBs
- Lowers satellite hardware cost, mass, and orbital power consumption
