An advanced airborne 5G connectivity system has been integrated to a Britten-Norman Islander aircraft, completing a series of demonstration flights.

The technology is being developed by a number of UK companies led by Stratospheric Platforms Limited (SPL), a leading Non-Terrestrial Networks telecoms developer, with design, integration and demonstration flights provided by manufacturer Britten-Norman.

On 18th July 2024, the project team were joined by potential customers and investors to observe the installation of the array under real flight conditions during an event at Britten-Norman’s Solent Airport MRO facility. The trial, conducted by Britten-Norman’s Flight Test Organisation, aimed to demonstrate the aircraft’s capability to operate safely with the large 5G phased array antenna installed.

The flight test programme in a turboprop BN2T-4S Islander included assessment of aircraft performance and handling qualities, covering both normal and emergency operation. This will support full certification of the system, enabling integration in terrestrial telecoms network at connection speeds of up to 200Mbps over 15,000km2.

Richard Deakin, CEO at Stratospheric Platforms Limited said: “We believe that our cutting-edge technology will provide unprecedented opportunities for global communication and create a more connected and inclusive world. Today’s flight test is an important step in the continuing validation of our technology breakthroughs.”
