EvtolSync: Sincronizzazione al Microsecondo della Telemetria di Volo e Armonizzazione ADS-B

EvtolSync Microsecond Multi-Aircraft Flight Synchronization Architecture

IEEE 1588 PTP master clock, ADS-B 1090 MHz Extended Squitter harmonizer, and relative RTK-GNSS positioning

Central System: Flight Synchronization Core - IEEE 1588 PTP & ADS-B Engine

Aviation Architecture Nodes

• Precision Time Protocol (PTP) Master Clock
• 1090 MHz ADS-B In/Out Extended Squitter
• Relative Kinematic RTK-GNSS Receiver
• Multi-Sensor Timestamp Synchronizer
• Airspace Traffic Management Synchronization Hub

Architectural Layers & Protocol Stacks

• Nanosecond Precision Clock Synchronization (IEEE 1588v2 PTP / GPS-Disciplined Rubidium Oscillator): Distributing uniform, drift-free timestamping across all flight computers, sensors, and network switches with sub-microsecond precision.
• Surveillance Datalink Harmonization (1090ES ADS-B / 978 MHz UAT / Mode S Transponder): Harmonizing transmission intervals, eliminating RF squitter collisions, and ensuring 100% compliant position broadcasting.
• Inter-Aircraft Relative Positioning (Rel-RTK) (Carrier Phase Differential GNSS (CDGNSS)): Measuring relative distance between adjacent formation aircraft with centimeter accuracy at 100 Hz.
• Multi-Stream Sensor Temporal Fusion (Hardware Hardware Trigger Generators / FPGA Timestamping): Aligning optical video frames, LiDAR point clouds, and radar returns onto identical microsecond timestamps for AI fusion.
