Altitude Angel, Microsoft and Imperial College London team up to respond to key challenge facing drone industry: automated traffic management

Today, we are pleased to announce the results of a six-month long research project conducted by Altitude Angel and Imperial College London, supported by Microsoft.

How to successfully integrate manned and unmanned aviation into our skies safely is widely considered to be one of the factors limiting the transformative potential of civilian drone technology, and proving how this can be achieved while meeting rigorous aviation safety standards is a critical concern.

The Challenge

Around the world, drones are typically restricted to flight within the visual line-of-sight of their human pilot. While the uses of drones are many and varied, this restriction does severely hamper the transformative potential of this technology, limiting its usefulness. Although many drones are themselves capable of basic ‘automatic’ flight, the lack of any traffic coordination, awareness of other – manned and unmanned – airspace users or even proper data about the regulatory environment are all hindrances to having these restrictions lifted.

Traditional methods of air traffic control do not scale well to the unmanned traffic environment (and, for the most part, would be inappropriate) and there are many complex challenges to be overcome in developing an automated substitute. “That’s why this study, led by Altitude Angel and Imperial College London, has such a profound relevance to the development of the drone industry on a global scale”, said Richard Parker, Founder & CEO of Altitude Angel.

The Research

Building on Altitude Angel’s existing technology and under the guidance of our engineers, 14 undergraduate Computing students from Imperial College London split into two teams and went head-to-head to find the most effective algorithms for enabling drones to go about their business while avoiding each other, other air traffic and hazards.

The students then had to verify their algorithms against a series of tough simulation scenarios powered by Altitude Angel’s drone cloud platform, designed to be representative of possible “real-world” scenarios. This means, in practice, that the teams had to cater for both risks known at pre-flight as well as risks that become apparent during a flight; factors which are often omitted in other emerging UTM systems.

Using just a modest amount of computing power in Altitude Angel’s cloud, the students proved that over 1,000 drones could successfully co-exist with both manned and unmanned aviation in a dense, 1 km² area, avoiding no-fly zones and crossing paths at a safe distance without human intervention, achieving a 0% rate of conflict.

Professor William J Knottenbelt, Department of Computing, said “This project demonstrates why it is so mutually beneficial for computer science students to interact with industry. In this instance, our students were empowered to achieve to the best of their potential by Altitude Angel, who provided valuable domain expertise, test infrastructure and regular feedback, and Microsoft, who provided cloud-based compute resources. It also shows the importance of being open to ideas from other disciplines: in this case the physics-based notion of treating the drones as charged particles which naturally repel one another turned out to be a critical element of the solution.”

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.

In 2021 Altitude Angel won a prestigious Air Traffic Management (ATM) Magazine Award in the ‘UTM Service Suppliers’ category, which recognises pioneering technologies and procedures developed by UTM service suppliers to advance safety and complex operations, for its Pop-Up UTM platform.  Read more about the awards here.

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