Drone technology is constantly evolving as new innovation and big investment in bringing more advanced drones to the market every few months. UAV technology or unmanned aerial vehicle technology is the most popular drones on the market .
UAV technology in the widest aspect covers every thing fron the aerodynamics of the drone, materials in the manufacture of the physical UAV , to the circuit boards, chipset and software which are the brains of the drone. The UAV is ideal to explain drone technology because it has everything in one package . It includes UAV , gimbal and camera. They are also equipped with different state of art technology such as infra-red cameras (military UAV) , GPS and laser. Drones can be controlled by remote control systems or a ground cockpit. The remote control system is the wireless communication device using the 5.8GHz frequency band. Gimbal technology is vital to capture equality aerial photos, film or 3D imagery. The gimbal allows for any vibration from the drone to not reach the camera.
Drones can carry sensing equipments to assist with any number of functions. Geological surveying , agriculture, archeology. Heat sensors detect the temperature of livestock , the presense of water , water temperature. They are vividly used in commercial and motion picture film making . Drones have made it possible to survey land. Originally developed for the military to deliver goods to ground troops are now used for delivery of commercial goods.
Among all these application there is a lot of hype about where the drones will take us. A lot is still very much in flux. Rules keep changing and the freedom to fly are curbed in many countries. Hope the world citizens make the best use of them for the good of the mankind.
