Altaeros’ pioneering autonomous tethered aerostats provide wide-area coverage for first responders, rural communities, and remote applications.

OCTOBER 13, 2020: Today, Massachusetts-based aerial platform innovator, Altaeros, announced its new ST-Flex autonomous aerostat. ST-Flex is a portable, rapidly deployable SuperTower™ designed to simplify and accelerate network deployments for industrial IoT, disaster response, rural connectivity, and many other data-intensive applications. With set-up times under one day, the ST-Flex combines rapid response capabilities with the operational and cost efficiency of Altaeros’ best-in-class autonomous aerostats. Altaeros will begin shipping the ST-Flex in early 2021. More information:


ST-Flex carries 130+ lbs (60 kg) of electronic payloads up to 1,000 feet (305 m) high, for weeks at a time. Power and fiber optic cables imbedded in the tethers provide robust power and connectivity between the payload and ground equipment. Together, these features provide a level of performance and flexibility unparalleled amongst commercial unmanned aerial vehicles (UAVs). Aerostat Autopilot™, Altaeros’ proprietary aerial robotics control system, eliminates on-site crew for daily operations and ensures the highest level of reliability, making ST-Flex the most cost-effective aerostat solution in its class. With its autonomous capabilities and quick set-up, deploying airborne assets for critical connectivity is a breeze with the ST-Flex.

“There is an immense need for a high capacity, rapidly deployable connectivity solution for hard-to-reach areas and critical situations,” said Altaeros CEO, Ben Glass “The ST-Flex empowers our customers to quickly respond and deliver communications to the communities and businesses that need it most, when they need it most. We’re excited to see the ST-Flex in action as our first international customer takes delivery early next year to enhance their crisis response capabilities.”
