Reusable balloons rival satellites for high-quality aerial imagery

Science

The balloons can photograph up to 1,000 square kilometres per hour

Spotted: Deployed above commercial airspace and below low-Earth orbit, Urban Sky’s Microballoons are a quickly deployed aerial imagery solution that makes high-resolution data capture more affordable for businesses, governments, and farmers. The helium-filled balloons drift horizontally in the stratosphere, using custom-built cameras and other image-gathering devices to create large-scale photos.

The camera rotates depending on the speed of the balloon’s travel, and images are stitched together to produce up to 1,000 kilometres of imagery data per hour. Once the entire area has been photographed, a ground team remotely activates the return system, using the weight of the cameras and sensors to turn the balloon inside out and deploy a parachute when at a low enough altitude.

Both the cameras and balloon are reusable, which passes financial savings onto businesses and organisations unable to afford the current cost of satellite imagery. Urban Sky envisions the photography being useful for a considerable range of purposes, including mapping urban changes, monitoring widespread utility assets, and providing rapid reviews of natural disaster zones. Already in use by several private organisations in the western United States, Urban Sky recently announced plans to develop a dedicated forest fire monitoring version for the US Air Force.

With tethered drones capable of providing on-the-spot internet access and a drone-powered water sampling device available, aerial solutions to natural disasters are becoming more commonplace.
