IntroductionAn unmanned aerial vehicle (UAV), known as a drone, is an aircraft without a human pilot.
Drone stands for Dynamic Remotely Operated Navigation Equipment
Its flight is either controlled autonomously by computers or under the remote control of a pilot on the ground
The earliest attempt at a powered unmanned aerial vehicle was A. M. Low's "Aerial Target" of 1916After World War-I, including the first scale RPV, developed by the film star and model airplane enthusiast Reginald Denny in 1935The birth of U.S. UAVs began in 1959 when United States Air Force officers, concerned about losing pilots over hostile territory.The August 2 &4, 1964,U.S. Navy initiated America's highly classified UAVs into their first combat missions of the Vietnam War.
UAV is a System
Sub-System of UAVsCOMMUNICATIONS:-
Operates on ultra high frequencyCommunicates with ku-band systemOperates with uplink frequencies from 15.15 to 15.35 GHz and downlink frequency 14.40 GHz to 14.83 GHz
Avionics use satellite based system such as GPS and WAASIt calculates position automatically
Includes GPS systemHigh resolution video cameraSuper high resolution still camera
COLLISION AVOIDANCE SYSTEM:-
Use traffic and collision systemSmaller aircraft use simple traffic alerting systemAircraft use ground proximity warning system
WEATHER SYSTEM:-Use weather radar and lighting detector system
Rustom is a Medium Altitude Long Endurance unmanned combat air vehicle being developed by DRDO.
Digital Flight Control and Navigation System, Automatic Take off and Landing.
Aerodynamic configurations, High aspect ratio wing, Composite airframe integrated with propulsion system, De-icing system for wings
The DRDO Nishant is an developed by India's ADE .Day/night capability training vehicle.Its range of Service ceiling:3,600 m (upto 11,800 ft)
Lakshya is an Indian remotely piloted high speed target drone system developed by ADE of DRDO.Service ceiling: 9,000m (29,528ft) 5,000 metres (16,404ft) with towed target.Launch: Rocket Assisted

Remotely piloted vehicles will never fully replace manned aircraft
They can perform an increasingly sophisticated array of missions due to their small size and decreased radar.
To wholly replace man would be expensive and technically risky.
UAS should be only considered for certain types of missions for which it can be a cost effective
With a continuing trend of miniaturization in electronics, the UAV can be made much smaller and cheaper
Size largely determined by the size of the payload,
IN COUNTER TERRORISM ACTIVITY:IN COMMERCIAL AERIAL SURVEILLANCE:
IN OIL, GAS AND MINERAL EXPLORATION & PRODUCTION:
IN SCIENTIFIC RESEARCH
IN ARMED ATTACKS
IN SEARCH & RESCUE
Doesnot contain, or need, a qualified pilot on boardCan enter environments that are dangerous to human lifeReduces the exposure risk of the aircraft operatorPerforming visual or thermal imaging of a regionMeasuring cell phone, radio, or, TV coverage over any terrainCan be programmed to complete the mission autonomously even when contact with its GCS is lost
ImmoralCivilian casualtiesAngers many people in foreign countries(infringe upon sovereignty) Can be hacked or given virusesToo small for transportation of materialsLow resistance to weatherCannot refuel in flightIf contact is lost with the ground station, the vehicle may be lost.
CONCLUSIONUnmanned Aerial Vehicles are an exciting field in the world of aviation, with new discoveries. Over the next 16 years, UAVs will become a significant component of military, civil, and perhaps even commercial aviation.
However, the very dynamic nature of the field also creates a significant amount of uncertainty. The wide range of UAV physical and performance characteristics, many of which will be very unlike any current aircraft, will place additional challenges on an air traffic management system.
