GlobalNavSat Cryptographic Multi-Constellation PNT Engine
Simultaneous tracking of OSNMA Galileo, GPS M-Code, and LEO Doppler cross-validation
Central System: Multi-Frequency GNSS Front-End - L1/L2/L5, E1/E5, B1/B2/B3 RF receiver
Network Nodes
- Multi-Frequency GNSS Front-End
- Galileo OSNMA / Chimera Engine
- LEO Carrier Phase Monitor
- Resilient PNT State Matrix
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)
