Titan Aerospace’s solar-powered atmosats are designed to remain airborne for months or years at a time.

Titan’s atmosats are designed to cruise at 65,000ft (19,800m).

Titan’s atmosats will have 3,000 photovoltaic solar cells on their fuselage and wings to provide power.

Farming and weather research is one use envisaged for atmosats.

Spare solar energy taken on by an atmosat during the day will be stored to power the aircraft at night.
