In collaboration with the Northern Plains UAS Check Website (NPUASTS) and the Federal Aviation Administration (FAA), AURA Community Programs has accomplished a complete flight-test report evaluating voice-relay service efficiency throughout past visible line of sight (BVLOS) operations. The assessments, carried out in Mayville and Buxton, North Dakota, assessed the technical efficiency of AURA’s hybrid voice-relay structure towards RTCA DO-377 requirements for distant pilot communications.
BVLOS Voice Communications Testing and Outcomes
AURA’s structure integrates distant pilots with air visitors management (ATC) via a UHF command-and-control hyperlink and legacy VHF techniques. Testing demonstrated measurable efficiency metrics important for protected BVLOS integration into the Nationwide Airspace System. Latency averaged beneath 192 milliseconds, with 99% of transmissions remaining beneath 238 milliseconds—effectively inside FAA-relevant thresholds for distant pilot situational consciousness and controller responsiveness.
Voice readability validation employed the Perceptual Goal Listening High quality Evaluation (POLQA) commonplace, a globally acknowledged technique for evaluating speech transmission throughout communications networks. Scores met or exceeded FAA benchmarks throughout all check situations, with intelligibility confirmed for each female and male voice samples. This testing simulated real-world terminal environments, with surrogate pilots and controllers speaking through AURA’s airborne and floor radios whereas impartial assessments have been carried out by a staff from the College of North Dakota Aerospace.
Function-Constructed Aviation Infrastructure
AURA’s community makes use of unique, licensed spectrum designed particularly for aviation purposes, delivering safe, low-latency communications for each crewed and uncrewed plane. The voice-relay system performs real-time conversion of analog voice to digital and again once more, sustaining stringent latency and intelligibility necessities outlined in RTCA DO-377B, the up to date commonplace printed in December 2023 for command-and-control hyperlink techniques.
Kevin Steen, CEO of AURA Community Programs, commented on the outcomes: “This report underscores what we’ve constructed: a dependable, aviation-grade voice hyperlink that delivers readability, velocity, and belief — exactly what distant pilots and air visitors controllers must function safely and confidently.”
Trevor Woods, Government Director of NPUASTS, added: “Clear, dependable voice communications are important for BVLOS flight. These assessments present that AURA’s system delivers — and we’re proud to assist advance the applied sciences that make protected integration doable.”
The FAA-sponsored testing was carried out beneath the Broad Company Announcement (BAA) program, underscoring federal funding in communications infrastructure for uncrewed plane integration. AURA and NPUASTS have launched supplementary video documentation of the flight assessments and technical validation on AURA’s web site and NPUASTS’s YouTube channel.
