Technical analysis and engineering reference.
Aviation authorities (FAA, EASA) demand Loss of Link (LoL) probabilities lower than 1e-7 per flight hour for uncrewed or highly automated passenger aircraft. Terrestrial cellular towers face structural limits: signal shadowing behind skyscrapers, upward beam tilt limitations, and terrestrial handoff latency.
To overcome single-path vulnerabilities, AirspaceInfra implements dynamic multipath packet duplication: - Command packets transmitted simultaneously over terrestrial 5G-A and Low Earth Orbit (LEO) satellite S-band links. - Onboard receivers deduplicating packets with zero packet jitter. - Dynamic QoS routing prioritizing telemetry and flight termination commands over low-criticality diagnostic logs.
C2 links must be impervious to man-in-the-middle attacks, GPS spoofing, and malicious command injection. Post-quantum cryptographic handshake protocols secure bidirectional flight authorization keys across every handoff transition.
