The Drone is part of a large category of small and medium-sized aircraft piloted by a ground pilot using a radio control.
During flight, drones can carry different types of sensors. The sensors (Payloads) can be a simple high definition camera or video camera or more complex sensors, such as infrared radiometric cameras and laser sensors.
The drone is associated with an on-board system which, in addition to controlling the navigation of the aircraft, manages the acquisition of data through the use of sensors.
This allows to acquire, often with the same aircraft, different types of data using various types of sensors.
