GlobalNavSat | PNT Résilient, GNSS Multi-Constellations et Systèmes Anti-Leurrage

GlobalNavSat protège le positionnement par satellite contre la guerre électronique: fusionnant GPS, Galileo, BeiDou et LEO en architectures PNT anti-leurrage.

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)

Systèmes PNT Résilients, GNSS Multi-Constellations & Technologies Anti-Leurrage

Core Engineering Areas

Galileo OSNMA Cryptographic Authentication — Verifying digital signatures on civilian navigation messages to prevent malicious GPS spoofing and ghost vessel creation.
LEO Constellation PNT Augmentation — Using high-power 500 km LEO signals that are 1,000x stronger than MEO GPS, penetrating indoor structures and jammer noise.
Controlled Reception Pattern Antennas (CRPA) — Multi-element antenna beamforming placing deep nulls in the direction of electronic warfare jammers.
