Architectural Layers & Protocol Stacks
- Physical & Data Link Redundancy (IEEE 802.3 / ARINC 664 Part 7 Dual-Rail Redundancy): Dual-rail copper and fiber Ethernet delivering 100BASE-TX and 1000BASE-T1 reliability with zero packet loss across simultaneous channels.
- Deterministic Virtual Link Scheduling (Virtual Link (VL) Shaper / Network Calculus Jitter Engine): Strict Bandwidth Allocation Gap (BAG) policing ensuring flight-critical control packets encounter zero buffer overflow jitter.
- Tactical Transponder & Surveillance Bus (RTCA DO-260C / Mode S Extended Squitter / ADS-B In): High-rate DO-260C compliant 1090 MHz Extended Squitter broadcast with cryptographic timestamping and position verification.
- Space-to-Air Broadband Tactical Gateway (Inmarsat SwiftBroadband-Safety / Starlink Aviation / FANS 1/A): Dynamic multi-orbit satellite routing switching between LEO constellations and GEO beams to preserve continuous high-security telemetry.
Flight Telemetry Metrics: < 1.2 µs (AFDX Switch Traversal Jitter) | 1 Gbps (Deterministic Port Line Rate) | 10^-9 (Undetected Frame Error Probability) | 100% (ARINC 664 P7 Conformance)
Deterministic Airborne Bandwidth for Modern Integrated Avionics
Legacy point-to-point ARINC 429 wiring bundles added hundreds of kilograms to aircraft gross weight. AvionicsComm delivers certified Avionics Full-Duplex Switched Ethernet (AFDX) architectures providing deterministic bandwidth allocation, microsecond jitter bounds, and robust multi-bearer space-to-air connectivity.
