A drone, in technological terms, is an unmanned aircraft. Essentially, a drone is a flying robot that can be remotely controlled or fly autonomously through software-controlled flight. Embedded with the plans , working in conjunction with onboard sensors and GPS.
Beacuse of it’s enormous applications, drones are being used in various fields. Fields like – industrial, medical, sports, military etc have major role using drone.
DRONE IN SPACE
Perhaps the closest thing to a UAV in space is the X-37B, which looks like a miniature version of NASA’s now-retired space shuttle. The unpiloted spacecraft completed four clandestine space missions.
Most of X-37B’s work is highly classified, making it difficult to speculate about the purpose of its missions. However, the Air Force has released some information about the fourth mission. In an email to Space.com in May 2015, Air Force spokesperson Capt. Chris Hoyler said the X-37B would have an experimental propulsion system and would help engineers investigate how well various materials perform in space.
Although not technically classified as drones (since they operate beyond Earth’s atmosphere), it could be argued that several of the spacecraft that visit the International Space Station are unmanned aerial vehicles as they carry only cargo and no pilot. There are several of these vehicles, including Russia’s Progress spacecraft, the (now-retired) European Space Agency Automated Transfer Vehicles, SpaceX’s Dragon and Northrup Grumman’s Cygnus.
The applications for camera drones are endless. In addition to capturing outdoor adventures, they are used today in pro film, real estate, business marketing, search and rescue, inspection, security, land surveying, and many more industries. Intermediate models are often in the $200 – $1,000 ( 1400- 70000 INR ) range and come with great cameras, superior stability in the wind, and automatic flight modes (such as Return Home and Hold Altitude) which make flying a breeze. Intermediate drones are sometimes referred to as “prosumer” drones as they are able to be used professionally and personally.
Advanced drones are generally used by professional cinematographers and cost upwards of $1,500 (105000 INR). These drones offer unmatched speeds, acceleration, stability, image processing and more. Many support CinemaDNG and ProRes recording. Like many intermediate “prosumer” drones, advanced drones are often ready-to-fly right out of the box, and offer intuitive flight modes.
