Enduring Atmospheric Platforms

ARIA has launched a programme backed by at least £50 million to unlock the stratosphere as a persistent operating environment. The goal is to solve the interdependent challenges of flight and energy to create a resilient and sustainable platform layer between Earth and space. Success will be measured by a single, galvanising demonstration: keeping a platform aloft for one week while maintaining line-of-sight to a fixed ground point and continuously powering a 300W payload. This technical breakthrough will provide the physical backbone required for next-generation advanced communications, serving as a critical enabler for the projected £13–20 trillion annual economic potential of AI.

This programme is a 3.5-year effort focused on technical de-risking for low-cost, long-endurance aircraft that enable scalable high-altitude communications. To support the researchers and organisations funded by ARIA in bringing these breakthrough ideas to life, we sought proposals for segregated testing space, platform guidance, and validation.
