Airspace User Portal Proves Restricted Airspace Needn’t Be Off Limits

Madrid, 12 March:  Altitude Angel, a world-leading UTM technology company, today announced its airspace authorisation toolkit which provides the functionality behind the NATS Airspace User Portal (AUP) – giving ANSPs the ability to process and automate requests to operate drones within ATZs - has successfully completed its pilot stage.  

NATS will begin its roll out of AUP support for Un-manned Aerial Vehicles (UAVs) to six trial UK airports, beginning in April, with more set to follow thereafter. 

With less than 24 hours before the UK introduces new legislation restricting drone operations within the vicinity of airports, the success and wider roll-out of the airspace authorisation toolkit and AUP could not be more well-timed.  

Richard Parker, Altitude Angel, CEO and founder, said: “There is a growing need for states and critical infrastructure operators to manage the use of drones in and around restricted airspace.  Our partnership with NATS has demonstrated how drone users can be given the necessary authorisations to fly in these restricted airspaces safely, easily and securely, via AUP. 

“Following the widely reported disruption at Gatwick in the days before Christmas, the government have extended the restricted airspace around airports in the UK and other European states will inevitably following suit. However, there is undoubtedly a need to authorise legitimate drone use. Airspace authorisation toolkit and AUP makes it easy for the drone user to ask for permission and the automation in the tools we have built make it simple for the ANSP, or authoriser, to grant or deny authorisation.”  

Background to AUP

Working together, Altitude Angel has enabled NATS to deliver several key UTM-focused projects and is key to the NATS strategic roadmap on UTM for the next ten years.

In January 2018, NATS switched-on its Airspace User Portal (AUP), a public web site which interconnects directly to the UTM backbone provided by NATS’ deployment of GuardianUTM O/S.
