Stratospheric Drone: Astigan

Aerotrope are providing aero-structural design services to Astigan’s High Altitude Pseudo Satellite project.

Astigan Ltd was established in 2014 and is owned to 51% by the Ordnance Survey. The high altitude aircraft with a wingspan of 38m and weighing 149kg (including a payload of up to 25kg) will be deployed at 67,000 ft altitude, in order to combine the constant eye-in-the-sky presence of a satellite with accurate 3D mapping.

This technology will not only aid in the upgrading of the UK’s infrastructure, it could also benefit emerging technology areas such as future self-driving vehicles and other 'smart city' applications. 

First tests of endurance flight testing the Astigan unmanned aerial vehicle are scheduled to take place before the end of 2019, building up to 90 days non-stop.
