In the evolving landscape of global connectivity and Earth observation, AALTO’s Zephyr is a game-changer. This High Altitude Platform Station (HAPS) heralds the advent of the Stratospheric Age, a new era marked by direct-to-device connectivity and enhanced Earth monitoring.

Zephyr has revolutionized mobile connectivity, particularly in remote and rural areas. Its ability to cover a 7,500 square kilometer area, equivalent to the capacity of about 250 ground towers, is transformative. This makes it an ideal solution for expanding network coverage in sparsely populated or challenging terrains. By seamlessly integrating with mobile operators’ networks, Zephyr helps in extending services to previously unreachable locations. This advancement is not only technologically significant but also economically viable, aiding mobile network operators (MNOs) in expanding their customer base and enhancing service quality.

In terms of Earth observation, Zephyr’s technology is unparalleled. Equipped with Airbus’ state-of-the-art OPAZ system, it offers high-resolution electro-optical and infrared imagery, along with real-time video capabilities. This allows for persistent, round-the-clock monitoring of the Earth’s surface, a feat unmatched by other technologies.

The versatility of Zephyr extends to government services. Its stratospheric capabilities are well-suited for a range of applications, from wildfire prevention and environmental monitoring to disaster relief, border control, maritime surveillance, and defense operations. These services are crucial for addressing various challenges and enhancing security and safety measures.

Emphasizing sustainability, Zephyr operates entirely on solar energy. Its emission-free flight aligns with the United Nations Sustainable Development Goals (SDGs), showcasing a commitment to the planet’s health and future generations.
