SatelliteTwins: 거대 위성군 궤도 디지털 트윈 및 정밀 궤도력 시뮬레이션

SatelliteTwins는 메가 콘스텔레이션 역학, 일식 열 충격, J2/J4 중력 섭동 및 위성 간 레이저 메시 토폴로지를 시뮬레이션하는 초정밀 궤도 디지털 트윈을 구축합니다.

SatelliteTwins Mega-Constellation State Vector & Perturbation Engine

High-order gravitational harmonics, solar radiation pressure, and atmospheric drag integration

Central System: SGP4 / High-Precision Orbit Propagator - Numerical integration including EGM2008 120x120 harmonics

Network Nodes

  • SGP4 / High-Precision Orbit Propagator
  • Orbital Eclipse Thermal Simulator
  • Dynamic OISL Network Simulator
  • Autonomous Conjunction Assessment

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)
