Drone is a common name for Unmanned Aerial Vehicle (UAV), basically a class of aircrafts who flight remotely controlled from the ground, or even fully autonomously without any human piloting. The simple remote control is older and still more common, although with better technology is increasingly being employed an onboard computer for the autonomous flight. As many other inventions, even drones were originally developed for military purposes. Even though that they are being deployed for more and more various civil applications nowadays, the term “drone” is still a wee bit confusing for common people. This growing number of civil applications includes for example precision agriculture, aerial thermography, photography or cinematography, surveillance, firefighting, pipelines and building structures inspecting, land survey and many others.
Growing popularity of the drone civil employment of course means that this is getting to be a serious industry and bussiness. Moreover, there can be observed a promising cooperation between the producers of drones and other hi-tech technologies, university departments and the end users. Generaly speaking, we can suppose that in close future will drones replace man in tasks which are dangerous, tricky or hardly feasible without flying. Although the idea of an aircraft without a pilot is not anything new, more common using of drones became broader in past few decades. Many of drones have been deployed in the Gulf war, since 90´s they also have been using for rescue, search and non military purposes. The more obvious difference between the UAVs lies in configuration. There are drones with multiplied engines, so called multicopters, or drones with the wings, which actually remind tiny airplanes.
If you have a drone in a multicopter form, it usually means that the whole device is more steady, moveable, and able to take off from a very small starting spot. That´s why this kind of drones is very often used for filmmaking, aerial photography, thermography or surveillance. The wing form has normally better flight time endurance than the multicopters. Drones are also often equipped with some sensors, including infrared cameras, multispectral cameras, gamma ray sensors, biological or chemical sensors. These are mounted to a drone´s gimbal and using for plenty of applications. Even with a low cost drone can be done aerial surveillance of large areas, like wildlife mapping, pipeline checking or rescue operations. Moreover, even motion picture filmmaking with a drone is much cheaper than with using a real manned helicopter.
