context_page_description: An unmanned aerial vehicle is an aircraft without a human pilot on board and a type of unmanned vehicle. UAVs are a component of an unmanned aircraft system; which include a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator, autonomously by onboard computers or piloted by an autonomous robot.
  Compared to crewed aircraft, UAVs were originally used for missions too "dull, dirty or dangerous" for humans. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications, such as policing and surveillance, product deliveries, aerial photography, infrastructure inspections, smuggling, and drone racing. Civilian UAVs now vastly outnumber military UAVs, with estimates of over a million sold by 2015.
context_section_description: The malicious use of UAVs has led to the development of counter unmanned air system (C-UAS) technologies such as the Aaronia AARTOS which have been installed on major international airports. Anti-aircraft missile systems, such as the Iron Dome are also being enhanced with C-UAS technologies.
