Navigating uncharted territory in the telecommunications ecosystem, Stratospheric Platforms Limited (SPL) alongside other UK giants, aims to forge advanced airborne 5G connectivity. With an ambitious endeavor backed by Britten-Norman and Marshall Futureworx, the collaborative effort seeks to birth a High-Altitude Platform with an airborne antenna – a revolution steering us to high-performing 5G from the stratosphere itself. Imagine an unmanned aircraft, fuelled by liquid hydrogen, its vast wingspan of 56 meters and lightweight structure promising flight endurance of over a week.
