Ready to take your career stratospheric? AALTO is a global leader in the stratosphere. We design, manufacture and offer Earth observation and connectivity services using our record-breaking Zephyr High Altitude Platform Station (HAPS) solar-electric unmanned aircraft, capable of staying in the stratosphere for days, weeks, and months at a time. Powered entirely by the sun, Zephyr operates above 60,000 feet, high above conventional air traffic. As a new layer in Earth observation and connectivity ecosystems, Zephyr is positioned between satellites and more conventional terrestrial assets – filling in the operational gap between the two layers, while remaining a complementary solution capable of working in a system of systems. Services delivered with Zephyr can empower government and commercial customers with capabilities to see and sense or connect from the stratosphere – making a meaningful impact on the ground, from the skies.
