Advanced Research Agency Backs High-Altitude Communications Platforms

The UK’s Advanced Research + Invention Agency (ARIA) is investing £70 million in 18 projects to develop aircraft capable of operating persistently in the stratosphere. The goal is to deliver communications coverage from above the UK, with a primary target of supplying 300W to a communications payload for a week. The program funds work across three technical areas, including enabling technologies, systems integration and testing, and deployment and communications architecture. This initiative was reported by Aerospace Testing International.
