AvionicsComm 借助适航认证的 ARINC 664 航空级以太网交换机、抗欺骗 ADS-B 链路及高弹性星地数据网关，为现代商用客机、国防空中平台与 eVTOL 飞行机队构筑确定性互联中枢。

AvionicsComm Deterministic Network Topology

Redundant AFDX End-Systems, Dual-Star Switches & Multi-Band Tactical Gateways

Central System: Dual-Redundant AFDX Switch Fabric - Deterministic Bandwidth Broker

Aviation Architecture Nodes

  • Flight Control End-System A/B
  • FADEC Engine Control Bus
  • DO-260C ADS-B In/Out Unit
  • Cockpit Display Server (ARINC 661)
  • LEO / GEO Satellite Terminal

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)

面向现代集成航电的确定性机载带宽

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.
