Drones
| With all the publicity and controversy surrounding drones, have you ever wondered what makes them work? |
Formally referred to as unmanned aerial vehicles (UAV), drones are essentially flying robots. Traditionally used in situations considered too dangerous for human pilots, drones have since provided a variety of applications, both personal and commercial. Also used for spying purposes, drones are not without a serious degree of controversy. However, steps are being taken to control drone air traffic and therefore deal with the privacy issue.
So how do drones work, i.e. what is the technology involved?
Degree of Human Intelligence
No matter the size of the drone or what it’s used for, it requires some degree of human intelligence to control movement. However, drones are likely getting “smarter,” with adaptive control techniques no doubt in the tiny vehicles’ future.

The Satellite Component
When a drone takes off, it is controlled via direct data link from a ground-control station. This occurs until the drone leaves the line of sight. Once that happens, the ground-control station switches to a satellite link. The satellite subsequently controls the aircraft, though the drone also uses GPS to provide its position.Should the drone lose its communication link, it will fly in circles for hours or return to the base until the link is reestablished. Drones can also crash if they run out of fuel before contact is made.
Cameras and Other Features
Most drones are equipped with special cameras that capture images of the subject or target. These images are sent back to the person or people operating the drone. Cameras provide color or black and white images depending on the model. Drones may also include features such as infrared imaging for low-light conditions, radars, and lasers for targeting purposes.Learn more about drone technology and purchase drone products and accessories by contacting Dronefly today.
