LEOGeolocation | 저궤도(LEO) 고정밀 위성 측위 및 고속 도플러 거리 측정 체계

LEOGeolocation은 극단적인 도플러 편이 곡선과 기회 신호를 활용하여 전파 방해에 강한 위치 수정을 제공하는 LEO 메가 군집 기반 고정밀 위치 추적을 제공합니다.

LEOGeolocation Rapid Doppler Curve Fitting Pipeline

Instantaneous user position triangulation derived from LEO orbital pass geometry

Central System: Low Earth Orbit Constellation - 550 km altitude, 7.5 km/s orbital velocity

Network Nodes

  • Low Earth Orbit Constellation
  • Direct RF SDR Front-End
  • Non-Linear Doppler Curve Solver
  • Authenticated 3D Coordinate

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)
