ST-Flex carries up to 130+ lbs (60 kg) of payload for weeks at a time, at heights up to 1,000 feet (305 m) above ground. At this height, ST-Flex can cover the same area as 10+ ground-based towers. Power and fiber optic cables embedded in the tethers provide robust power and connectivity between the telecommunications payload and ground equipment. Together, these features provide a level of performance and flexibility unparalleled in the unmanned aerial vehicle (UAV) category. Aerostat Autopilot™, Altaeros’ proprietary suite of autonomous control software, eliminates on-site crew for daily operations and ensures the highest level of availability, making ST-Flex the most cost-effective aerostat solution in its class. With ST-Flex, Altaeros is significantly reducing the barrier to deploying airborne assets for critical connectivity across a range of applications.

“ST-Flex exceeded our expectations during the recent customer acceptance tests,” said Altaeros CEO, Ben Glass “We are excited to begin shipping ST-Flex to wireless carriers next month, to help them deliver global connectivity solutions to communities in need.”
