Air Traffic Control (ATC) depends on voice communications that are clear, reliable, and intelligible. Whether for ground-to-ground coordination between control centers or air-to-ground exchanges with pilots, voice quality is mission-critical.
Any degradation in audio performance — including distortion, latency, or intelligibility loss — can directly affect operational efficiency and, above all, safety.
In complex ATC environments, the communication chain includes multiple interconnected audio systems such as radios, gateways, recording systems, and switching equipment. Each element may introduce gain variations, noise, or signal processing effects, making objective end-to-end voice quality assessment particularly challenging.
In the transition toward IP-based and 5G-enabled communications for critical services, these challenges become even more significant. New network architectures can introduce latency, jitter, and audio processing variability, requiring objective and advanced measurement tools to ensure performance equal to or better than legacy systems.
Air Navigation Service Providers (ANSPs) Challenges
Operational Value for ANSPs
| Upgrade Validation | Audio diagnostics | Continuous monitoring | Acceptance testing |
| Quality verification after updates and system changes | Rapid anomaly identification across the audio chain | 24/7 supervision with automated MOS alerts | Equipment compliance validation against standards |
