NTN Satellite: Бортовая регенеративная обработка, полезные нагрузки gNodeB и SDR-транспондеры

NTNSatellite описывает переход от аналоговых ретрансляторов прямой ретрансляции к полностью цифровым регенеративным нагрузкам с демодуляцией PHY, коммутацией пакетов и функциями 5G Core на орбите.

NTNSatellite System Architecture

Core architectural topology and protocol interaction of ntnsatellite.com

Central System: Space gNodeB - Regenerative Payload

Network Nodes

  • Radiation FPGA
  • Onboard 5G Core
  • Laser Cross-Link
  • Digital Channelizer
  • Direct Decryption

Architectural Protocol Layers

  • User & Terminal Access Layer (3GPP Rel-17/18 NR-NTN & IoT-NTN): Direct communication from smartphones and IoT sensors to satellites
  • Space-Borne Radio Access (gNodeB / Transponder) (Regenerative Digital Payloads & Bent-Pipe Transparent Processing): In-orbit demodulation, digital beamforming, and spectrum channelization
  • Inter-Satellite Mesh & Space Transport (Optical Inter-Satellite Links (OISL) & 60 GHz V-Band Cross-Links): Autonomous multi-hop laser packet routing in vacuum at the speed of light
  • Ground Teleport & Core Cloud Ingress (High-Throughput Q/V-Band Gateways & Optical Ground Stations): Terabit feeder link downlinks connected directly to cloud hyperscalers

Key Metrics: 100 Gbps+ (Optical Cross-Link Bandwidth) | <25 ms (LEO Propagation Latency) | ±50 kHz (Doppler Shift Compensation) | 99.999% (Constellation Transport SLA)
