OISLGateway | 우주-지상 광 다운링크 및 클라우드 다이버시티 지상 게이트웨이

OISLGateway는 적응 광학으로 대기 난류를 극복하고 지리적으로 분산된 지상국으로 구름 차단을 우회하여 우주 레이저 다운링크와 지상 광섬유망을 연결합니다.

OISLGateway Space-to-Ground Optical Downlink Architecture

Direct-to-ground 100 Gbps laser transmission with real-time deformable mirror wavefront correction

Central System: LEO Satellite Optical Terminal - 1550nm downlink laser transmitter (5W)

Network Nodes

  • LEO Satellite Optical Terminal
  • Atmospheric Boundary Layer
  • Ground Optical Receiver (OGS)
  • Terrestrial Fiber PoP

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)
