Architectural Layers & Protocol Stacks

• Ruggedized Physical & Thermal Enclosure (Conduction-Cooled ATR Chassis / VITA 48 REDI): Dissipating 200W of heat without external fan air, surviving 20g shock and sustained aerospace vibration.
• Silicon Hardware Safety Enclave (DO-254 DAL A FPGA / Fault-Tolerant Multicore): Providing lockstep execution, ECC memory scrubbing, and hardware watchdog timers to catch single-event upsets.
• Spatial & Temporal Memory Partitioning (ARINC 653 Operating System Hypervisor): Guaranteeing that a software fault in a low-criticality app cannot starve CPU time or corrupt flight-critical memory.
• Open System Architecture Interoperability (FACE Technical Standard / SOSA Consortium): Enabling rapid plug-and-play swapping of flight software modules across diverse airframe platforms.

Flight Telemetry Metrics: DO-254 DAL A (Hardware Silicon Certification Level) | -55°C to +105°C (Operational Temperature Range) | Zero Crosstalk (ARINC 653 Spatial Partitioning) | VITA 48 REDI (Ruggedized Conduction-Cooled Standard)
