SpaceGeolocation Orbital Spectrum Sensing Architecture

Continuous 50 MHz to 18 GHz wideband RF spectrum ingestion and automated emitter classification

Central System: Spaceborne Wideband SDR - 50 MHz to 18 GHz continuous RF sweep

Network Nodes

Spaceborne Wideband SDR
Onboard Neural Signal Classifier
Intersatellite Coordination Mesh
Global Dynamic RF Heatmap

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)
