What is Unmanned Air Vehicle?

Unmanned Air Vehicle (UAV), commonly known as a drone also referred to as a Remotely Piloted Aircraft (RPA) is an aircraft without a human pilot on board. Its flight is controlled either autonomously based on pre-programmed flight plans or more complex dynamic automation systems or by the remote control of a pilot on the ground.

UAVS consist of number of sensors placed on the vehicle so that it can take inputs from the working environment and work autonomously in fully autonomous drones.
