The Global Observer, an unmanned aircraft system (UAS), is a cost-effective communications and surveillance platform that can stay aloft at 65,000 feet for a week. It is designed to address an urgent national security need for a persistent stratospheric platform and provides a means to satisfy numerous high value civil and commercial applications.
Mission applications include communications relay and remote sensing payloads for military or commercial customers. Multiple communications and remote sensing applications have already been demonstrated from this operating position, including high definition broadcast (HDTV) video, and third generation (4G) mobile voice, video and data using an off-the-shelf mobile handset.
