## About Altitude Angel

Altitude Angel was a UK-based aviation technology company founded in 2014, specializing in Unmanned Traffic Management (UTM) software.

The company developed the GuardianUTM platform, a cloud-based solution designed to facilitate the safe integration of autonomous drones into global airspace. Its mission was to "unlock and unify the airspace," providing the digital infrastructure necessary for the routine and safe operation of Unmanned Aerial Systems (UAS). The GuardianUTM O/S platform offered a comprehensive airspace management system, supporting both European and global standards for drone traffic. Key features included real-time airspace data, collision avoidance capabilities, and APIs for third-party integration. Altitude Angel primarily served national aviation authorities, air navigation service providers, drone manufacturers, and commercial drone operators, focusing on B2B and B2G markets. The company was recognized for its innovative approach to digital airspace management before entering administration in October 2024, with its assets acquired by Indra Group in early 2025.
