NTNStandard: 通用非地面网络技术规范体系与多标准组织跨域协调框架

NTNStandard 作为全球非地面网络 (NTN) 标准领域的权威基准规范知识库，系统化梳理并归档 3GPP Rel-17/18/19、欧洲电信标准协会 (ETSI)、国际电联 (ITU-R) 无线电规则及空间数据系统咨询委员会 (CCSDS) 标准体系。

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)
