The system, designed for quick deployment, can restore networks disrupted by major disasters like earthquakes or tsunamis. On 18th July 2024, potential customers and investors witnessed the installation and testing of the 5G phased array antenna during a demonstration at Britten-Norman’s Solent Airport facility. The trial aimed to verify the aircraft's performance and handling with the antenna, assessing both normal and emergency operations, crucial for full system certification. This technology can deliver connection speeds up to 200Mbps over 15,000km².

The BN2T-4S Islander was selected for its robust design, all-weather capability, endurance, and payload capacity, making it ideal for such integrations. Its modular design also allows for rapid reconfiguration for other tasks.

The next phase will demonstrate the technology’s connection to a private UK-based national 5G network, marking a significant advancement in airborne telecommunications and bringing high-speed 5G connectivity from the sky closer to reality.

Richard Deakin, CEO at Stratospheric Platforms Limited said: “Stratospheric Platforms is dedicated to creating pioneering innovative solutions that transform the connectivity landscape. Our commitment to delivering high-altitude, zero-carbon, long-endurance communication platforms will revolutionize how the world stays connected, especially in remote and underserved regions. 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.”

Dr Garnet Ridgway, Head of Flight Dynamics at Britten-Norman, remarked: “This project demonstrates the full capabilities of both Britten-Norman as an accomplished trials organisation and the turboprop Islander as a highly capable trials aircraft. Working closely with our partners, the project includes deliverables from our design, manufacture, MRO, flight test and flight operations teams. It’s always satisfying to deliver a safe and effective flight test programme, but the huge potential of SPL’s system and the collaborative nature of the team made this one particularly exciting. The large and complex nature of the system places significant demands on the host aircraft. However, the BN2T-4S performed admirably; the combination of payload capacity, endurance, climb performance, twin engine reliability, robustness and electrical power generation makes it unbeatable for this mission.”
