An Unmanned Aerial Vehicle (UAV), commonly known as a "drone", is an aircraft without a human pilot aboard. Its flight is often controlled by either autonomous onboard computers, or the remote control of a pilot on the ground.

Historically designed for military uses, UAVs are nowadays used by small -but always growing- number of civil applications. They are often preferred for missions tagged as "dull, dirty or dangerous" for manned aircraft.

The vast majority of current civil drones are splitted in 2 categories:

Fixed Wings

Fixed wings drones are designed for long-distance assignments, and are more dedicated to:
    Surveillance (national borders, pipe-lines, windmills...),
    Observation (natural parcs, road traffic, excavations...),
    Cartography (quarries, fields, cities...),

Rotary wings

These are the more relevant for stand-by flights, or flights requiring a vertical scanning. Therefore they are appropriated for spotted inspections of:
    Nuclear plants,
    Flood barriers,

Aiming to combine cutting-edge technologies and the desire to be respectful towards our planet, Sunbirds designs and manufactures the first solar ultra-long endurance fixed wings drone.
