London, UK: Altitude Angel, the world’s most trusted UTM (Unified Traffic Management) technology provider, has today announced it is to accelerate and expand its planned deployment of aviation-grade ADS-B sensors to create the most comprehensive private, secure, and trusted source of ADS-B in the UK.

Altitude Angel’s focus is on building technologies that are incorporated into solutions which enable the safe integration of automated drones into the airspace. ADS-B is commonly used by general aviation and other air users to broadcast aircraft location and sometimes carried by drones.

Existing ADS-B networks – from well-established suppliers to new entrants – have been neither designed or built to support automated flight, and typically aren’t optimised for low altitude, low-latency applications; two characteristics which are key to enabling automated flight at scale. Many such suppliers have built their systems up using data from non-certified equipment, including hobbyists using low-cost hardware such as ‘Raspberry Pi’ computers and deployed ‘randomly’ in locations supported by enthusiasts. Whilst still very useful analytically, it doesn’t meet the quality bar for real-time use in navigation systems at low altitude.

The ADS-B sensor network Altitude Angel is expanding, in contrast, will be optimised for coverage at low altitude, provide for low-latency, and – critically – capable of ‘blending’ or ‘fusing’ data from those sensors with other large amounts of sensor data in real-time. This last step is key, because it enables correlation; when fused with Altitude Angel’s other sensor information, it is possible to ‘highlight’ aircraft which aren’t visible on any single channel, such as ADS-B, or to provide enhanced assurance to those seeking to rely on position data when multiple sources of data corroborate each other.

This enhanced capability contributes to Altitude Angel’s already extensive air-surveillance picture and enables the firm and its customers to have even greater confidence in its ability to help get them airborne without a pilot – truly automated flight. In such scenarios, data is key. But good data is critical.

With proposals to expand the adoption of ADS-B for drone and general aviation emerging in the UK, it is more important than ever to find ways to be able to trust that information within the emerging UTM sector. A reliance on ADS-B is, by its very definition (Automatic Dependent Surveillance – Broadcast), dependent on the aircraft operator equipping and switching-on their transponder. Anybody who wishes to fly incognito, particularly at low altitude, need simply not comply with the requirement and if the UTM company was solely dependent on ADS-B, they would be ‘blind’ to those aircraft.

Which is why Altitude Angel is investing in expanding its dedicated coverage with a purpose-built and strategically deployed ADS-B network which also has the vast and significant benefit of being combined with all the other information on its platform, to establish the most accurate ‘moving map’ of the UK’s low altitude skies.

“We’ve taken the step to expand our dedicated ADS-B network which has been purpose-built from the ground-up (literally) to focus on solving for low-latency, fusion, and corroboration – to enhance trust and utility for low-altitude airspace users,” said David Walter, Altitude Angel, Special Projects Lead. “There are still many examples of aircraft which don’t carry an ADS-B transponder, but even if it were a requirement for all aircraft to carry them, there’s no guarantee everyone would comply, the equipment would always work, signals could be detected (particularly at low altitudes), nor the signal could be verified. To a UTM company focused on safety and airspace integration, non-compliant actors are as important as compliant actors and existing solutions today only solve for those that are compliant.”

While ADS-B has other challenges associated with its use, particularly for uncrewed aviation, from spectrum to scale, a UTM company can still benefit from its use – but only when it can be combined with a system with the scale of our UTM.

Companies wishing to utilise the enhanced situation feed offered by Altitude Angel will be able to benefit from the enhanced ADS-B network from late summer this year, via its existing Developer Platform.

About Altitude Angel: 

Altitude Angel is an award-winning provider of UTM (Unified Traffic Management) software, enabling those planning to operate, or develop UTM/U-Space solutions, to quickly integrate robust data and services with minimum effort.

From a consistent, well-documented and standards-based platform, drone manufacturers such as DJI and cutting-edge software developers around the world use our Developer Platform to obtain rich, relevant, and local geofencing data, exchange and share flight plans, de-conflict their own flights in real-time and interface with national flight authorisation systems. A growing portfolio of enhanced capabilities help our customers to comply with current and future regulations and interface with changing national systems with only minimal effort.

Altitude Angel’s first party solutions also power some of the world’s leading ANSPs, aviation authorities and Enterprises, including LVNL (Netherlands) and Avinor (Norway), empowering them with new capabilities to safely manage and integrate drone traffic into national operations.

Today, Altitude Angel’s market-defining technology is providing a critical, enabling service on which the future of UTM, especially in controlled airspace, will be built across the globe.

By unlocking the potential of drones and helping national aviation authorities, ANSPs, developers and enterprise organisations, Altitude Angel is establishing new services to support the growth in the drone industry.

Altitude Angel was founded by Richard Parker in 2014 and is headquartered in Reading, UK.
