The rapid growth of drone operations in the UK is forcing a fundamental rethink of how we manage our skies. Traditional air traffic systems weren't designed for thousands of small, connected aircraft sharing low-altitude airspace — and scaling those systems downward simply isn't feasible.
At AirOS, we're taking a fresh approach: a distributed, dynamic Uncrewed Traffic Management (UTM) system that grows and shrinks automatically with demand.
What We're Building
AirOS Distributed UTM is designed around the idea of Unmanned Traffic Control Zones (UTCZs) — small, digital airspace "cells" that activate only when drone activity is detected.
Each UTCZ runs a lightweight AirOS zone server that:
- Tracks local air traffic via Remote ID broadcasts (BLE/Wi-Fi),
- Fuses data from airborne and ground sensors,
- Detects potential conflicts in real time, and
- Issues safe flight advisories or reroutes to nearby operators.
When activity ceases, the UTCZ automatically powers down, keeping operational costs and energy use to an absolute minimum.
This system scales organically: as more drones enter an area, additional UTCZs spin up and coordinate with their neighbours to manage boundaries and handovers. It's air traffic management that scales like the internet — local, autonomous, and resilient.
Dual-Role Hardware: Airborne and Ground
Each drone or site can host a compact AirOS Node — built on the Portenta X8 with Cat-M1 GNSS connectivity. These devices:
- Broadcast their Remote ID over Bluetooth and Wi-Fi,
- Detect nearby aircraft doing the same, and
- Relay all data over LTE-M to the active UTCZ server.
Nodes on the ground act as local verification points, ensuring data integrity and improving accuracy even where cellular coverage is weak.
Distributed Architecture, Central Insight
Every UTCZ feeds anonymised position and safety data into the AirOS UTM cloud, which provides national-level oversight, operator dashboards, and data sharing with authorities.
While each zone runs independently, the AirOS backend can aggregate data across the country — giving regulators, emergency services, and airspace managers a real-time national picture of drone activity without a single point of failure.
Future Integration
We're currently engaging with NATS Digital Services and the UK Civil Aviation Authority (CAA) to explore how this architecture can integrate with OpenAir and future Common Information Services (CIS).
The vision is for AirOS operators to be able to:
- Submit flight intent directly through the AirOS platform,
- Receive automated authorisations and airspace data in return, and
- Share live telemetry and status updates back to national systems in real time.
This is an essential step toward seamless U-space compliance — and an opportunity to show how distributed, cloud-native UTM infrastructure can complement the UK's Airspace Modernisation Strategy.
(Formal CAA support has not yet been secured; we've submitted an application to the AMS Support Fund to help demonstrate the concept through open data trials and real-world testing.)
Why It Matters
- Safety: Instant electronic conspicuity and real-time conflict alerts help prevent mid-air incidents.
- Scalability: Zones activate only where traffic exists, making the system cost-neutral when idle.
- Affordability: Low-cost nodes mean even small operators can comply with Remote ID and participate in managed airspace.
- Resilience: Each UTCZ operates autonomously — a fault in one area doesn't impact the rest.
In short, it's a UTM built for the way drones actually fly — distributed, adaptive, and intelligent.
What's Next
We're planning an early-stage trial programme through 2026, demonstrating live UTCZ activation, multi-drone coordination, and data sharing between airborne and ground nodes. All trial results will be released as open data to help industry and regulators understand how distributed UTM can support safe growth of drone operations in the UK.
If successful, the project will lay the groundwork for national-scale integration — giving every drone operator, from small businesses to emergency responders, a low-cost, compliant path into shared airspace.
Jake Aston, Founder, AirOS Operations Ltd: "We believe the future of airspace isn't centralised — it's distributed. By making airspace management elastic, affordable, and intelligent, we can unlock the full potential of unmanned aviation in the UK."
