OISLMesh | 衛星間光レーザーメッシュルーティングおよび動的コンステレーション動態制御

OISLMeshは動的軌道コンステレーション上で分散パケットルーティングを実装し、1機あたり4つの光ヘッドを維持して極域境界での経路再計算を実行します。

OISLMesh 4-Head Orbital Grid Routing Topology

Simultaneous intra-plane and inter-plane laser links with autonomous polar seam switching

Central System: Intra-Plane Forward Satellite - Constant distance optical link (+1 in plane)

Network Nodes

  • Intra-Plane Forward Satellite
  • Intra-Plane Aft Satellite
  • Inter-Plane Left Crosslink
  • Onboard L3 Space Router

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)
