Near-infrared image by agricultural drone Daedelus comparison, remote sensing in precision farming Farmers can operate in very large areas without getting tired. It saves enough time, labour cost and increase effectiveness of using farm inputs. It significantly reduces the cost of production at larger scale of farming. Remote sensing technology can be efficiently used through drone technology to bring global practice of precision agriculture in upcoming future. Creating a strong market system of agriculture is easily possible by using UAVs. Further more, this technology can be used to know status of landscape so that we can prevent the heavy loss of natural disaster before it happen. Drone can also be used for tracking farm animals and their related problems. Source: Maxpixel, 2016Īgricultural drones are mainly used for fertilizer, pesticide, weedicide application, insect-pest, plant disease estimation, and soil status estimation by capturing multi-spectral images ranging from near-infrared to visible spectrum for precising the agricultural system than before. It may have 4, 6 or 8 rotating wings as per requirement. It is mainly light weighted, have remote sensing technology extensions and also external equipment attached to it. This is the type of drone or modern drone that are especially designed and used in agriculture. Its design could be customized as per necessity. It can be used in different sectors like entertainment, security surveillance, transport, forestry, agriculture etc. Modern drone are generally light weighted and more efficient to be viable for multipurpose uses. UAV launch from an air-powered catapult.Used for security surveillance with good night vision technology Delta Quad VTOL fixed wing surveillance UAV.Used for searching and killing enemies by military This global pressure have created environment of huge investment easily done by investors for drone manufacturers ( Markets and Markets, 2020). It will happen so because every country are thinking about efficient and sustainable technology to ensure the food security of fast growing population in upcoming future. It has been recently estimated that the global market size of agricultural drones will increase from 1.2 to 5.7 billion US dollar between 2020 to 2025, with annual compound growth rate of 35.9%. It was first used in 1849 for war fight when Austrain force attack Venice ( Buckley, 2006). This technology have been using for various sectors like for military purpose, wars, security surveillance, scientific researches, forest protection, wild life conservation, disaster risk reduction, light good transportation and now in agriculture as well. Drone technology may be semi-automatic remote controlled by human or fully automatic robotic control system. It neither needs a physical pilot nor wired connection attached to it. The term ‘Drone’ stands for unmanned aerial vehicles (UAVs) that is operated by using remote control system.
