Wireless connectivity from the stratosphere

More than 3 billion people lack access to reliable broadband internet.

Bringing these under-served communities online creates opportunities for economic growth, improved education, and a more connected society.

Our mission is to make this happen.

We are building high altitude solar aircraft to provide continuous, year-round, direct to handset LTE or 5G to more than 90% of the world's population.

Our aircraft can expand network coverage to unserved areas at a fraction of the cost of terrestrial networks.
