NTNData: 비지상 빅데이터 파이프라인 및 궤도 엣지 객체 스토리지

NTNData High-Throughput Orbital Data Pipeline Architecture

Petabyte-scale in-orbit caching, compression, and scheduled ground-station burst downlinks

Central System: Synthetic Aperture Radar (SAR) Array - Generates 20 Gbps raw radar telemetry bursts

Network Nodes

• Synthetic Aperture Radar (SAR) Array
• Rad-Hard NVMe Storage Array
• 100 Gbps Laser Downlink Terminal
• Terrestrial Object Store (S3)

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)
