Unmanned Aerial Vehicles (UAVs) are aircrafts that fly without any humans being onboard. They are either remotely piloted, or piloted by an onboard computer. This kind of aircrafts can be used in different military missions such as surveillance, reconnaissance, battle damage assessment, communications relay, minesweeping, hazardous substances detection and radar jamming. However they can be used in other than military missions like detection of hazardous objects on train rails and investigation of infected areas. Aircrafts that are able of hovering and vertical flying can also be used for indoor missions like counter terrorist operations.

2. Introduction
 An unmanned aerial vehicle (UAV), known as
a drone, is an aircraft without a human pilot.
 Drone stand for Dynamic Remotely Operated
Navigation Equipment.
 Its flight is either controlled autonomously by
computer or under the remote control of pilot
on the ground.

3. Birth of UAV’s
 The earliest attempt at a powered unmanned
aerial vehicle was A.M. Low’s “Aerial Target ”
of 1916.
 After world war-I, including the first scale
Remote Pilot Vehicle, developed by the film
star and model airplane by R. Denny in 1935.
 The birth of U.S. UASV’s began in 1959 when
United State Air force offers , concerned about
losing pilots over hostile territory.

4. UAV is a “SYSTEM”
These are the Commercial UAV’s used in the entertainment and logistic area.
In December 2013, the DHL parcel service
subsidiary of Deutsche Post AG tested a
"microdrones md4-1000" for delivery of
medicine.

8. SUB-System of UAV’s
 Communications:-
 Operates on ultra high frequency
 Communicates with ku-band system
 Operates with uplink frequencies from 15.15 to
15.35 GHz.
 Navigation :-
 Avionics use satellite based system such as
GPS.
 It calculate position automatically.

9.  Monitoring :-
 Includes GPS system.
 High resolution video camera
 Super high resolution still camera
 Collision avoidance system:-
 Use traffic and collision system
 Smaller aircraft use simple traffic alerting system
 Aircraft use ground proximity warning system
 Weather system :-
 Use whether radar and lighting detector system

10. Indian UAV’s
 Developed by DRDO ( Defence Research &
Development Organization )
 Lakashya
 DRDO Rustam
Developed by ADE
 Fluffy
 Pawan
 Nishant

11. Uses of UAV
 In counter terrorism activity
 In commercial surveillance
 In oil, GAS and mineral exploration &
Production
 In transport
 In scientific research
 In armed attacks
 In Search & Rescue

12. Advantages:
 Does not contain or need a qualified pilot on
board
 Can enter environments that are dangerous to
human life
 Reduces the exposure risk of the aircraft operator
 Performing visual or thermal imaging of region
 Measuring cell phone, radio or TV coverage over
any terrain
 Can be programmed to complete the mission
autonomously even when contact with its gas is
lost

13. Disadvantage:
 Angers Many People In Foreign Countries
 Can Be Hacked Or Given Viruses
 Too Small For Transportation Of Materials
 Low Resistance To Weather
 Cannot Refuel In Flight
 If Connection Is Lost With The Ground Station,
The Vehicle May Be Lost.
