In aviation and in space, a drone, also called an “unmanned aerial vehicle,” or UAV, refers to an unpiloted aircraft or spacecraft.
To reduce weight and increase manoeuvrability, a typical unmanned aircraft is made of light composite material allowing military drones to cruise at extremely high altitudes. UAVs are controlled by remote ground control systems (GSC) and equipped with infrared cameras, GPS and laser (consumer, commercial and military UAV).
Applications of UAVs
Drones can be used for collecting breath samples from spouting whales for DNA analysis. In 2015, Researchers with the Woods Hole Oceanographic Institution to assess the health of whales living in the Stellwagen Bank National Marine Sanctuary used a custom-built drone to collect blow samples, the moist breath exhaled by whales, from 17 humpbacks off the coast of Cape Cod and from nine humpbacks swimming near Canada’s Vancouver Island.
In the present era, there are too many developments in precision agriculture for increasing crop productivity. The Unmanned aerial vehicle (UAV) – aircraft are used to spray the pesticides to avoid the health problems of humans when they spray manually. UAVs can be used easily, where the equipment and labours difficulty to operate.
Drones can capture images of erupting craters that would be impossible to get otherwise. They are very practical to quickly obtain good quality terrain images and photogrammetric data in almost all volcanic environments.
