Welcome to AALTO, a global leader in Stratospace. Based in Farnborough, AALTO is an Airbus subsidiary that manufactures, operates, and delivers services with its solar-powered, stratospheric platform: Zephyr. Zephyr’s persistence enables continuous flight for months at a time. Its current flight-time record of over 67 days in the stratosphere. From above 60,000ft, or 20km above ground, AALTO can deliver several applications including direct-to-device connectivity and high-resolution Earth observation. AALTO operates in a new operational layer between most of air traffic and low-Earth orbit, Stratospace. This is where high-altitude platforms led by Zephyr deliver services to commercial and government partners. We can help monitor environments, observe borders, track natural disasters and connect unconnected communities. Join us as we create a new domain of aerospace: Stratospace.
