SpaceMeshNetworks：多層マルチ軌道統合型宇宙ネットワークアーキテクチャ

SpaceMeshNetworksは、超低遅延LEOレーザーメッシュ、中軌道（MEO）大容量パイプ、静止軌道（GEO）リレーを統合した異種多軌道宇宙通信ファブリックを構築します。

SpaceMeshNetworks Hierarchical Multi-Orbital Space Backbone

Inter-layer optical and millimeter-wave feeder crosslinks between LEO, MEO, and GEO

Central System: Dense LEO Access Swarm - High-density cellular direct-to-device constellation (600 km)

Network Nodes

  • Dense LEO Access Swarm
  • MEO Intermediate Transit Node
  • GEO Persistent Optical Gateway
  • Orbital Software-Defined Network Controller

Architectural Protocol Layers

  • Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
  • Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
  • Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
