FSOCommunication | 空間光通信（FSO）システムおよび地上宇宙間光リンク

FSOCommunicationは可視線空間光通信を開拓し、HAPS、航空機、地上基地局間で免許不要のマルチギガビットレーザーリンクを実現します。

FSOCommunication Stratospheric-to-Ground Optical Backhaul

High-altitude pseudo-satellite (HAPS) laser bridging to urban telecom towers

Central System: Stratospheric HAPS Drone / Balloon - 20 km altitude solar-electric optical terminal

Network Nodes

  • Stratospheric HAPS Drone / Balloon
  • Multi-Wavelength Optical Beacon
  • Urban Telecom Tower FSO Node
  • 5G/6G Core Transport

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)
