Discover How Drones Manage to Stay Up in the Air

By on Last modified: June 8, 2018

Drones are built from parts known as unmanned aerial vehicle technology and it covers everything from the aerodynamics of your drone, the materials it is made from, the circuit boards to the software that runs it. The DJI drones are one of the most popular drones on the market, specifically the Phantom 3. This drone became very popular with cinematographers, even tough it’s slightly older now, the technology used for its creation is now present in the very latest drones. Read on to find out how exactly the latest types of drones operate.

How Drones Work

Nearly all drones are made from a light composite in order to reduce weight and increase the manoeuvrability of the unit. The composite material is also very strong and it is used in the making of military drones. Varying from one model to the next, there is a wide range of technology that goes into a drone, such as infra red cameras, GPS navigation and a lot more. However, they are usually divided into two parts – the drone itself and the control system. In the nose is where all the sensors and the navigation system are located, the controller send direction to the sensors which later translate the information into movement. The rest of the body is made up of parts that stabilize flight, reduce vibrations, and hold the drone together.

Types and Sizes

It seems as if there is no end to the type of drones you can find. Everything from the smallest foldable ones to the largest drones used for military purposes such as the predator drone. Going up a notch on the size large scale we get to unmanned aircraft ones that have fixed wings and need a short runway to get them in the air – they are very stable but have trouble turning. The DJI drones however, especially the newer models like the Phantom 4, offer great manoeuvrability and can turn sharp corners easily.

Radar Positioning and Returning

All of the latest drones have state of the art navigation system that allows you to control them and help the drone navigate through their surroundings once an order has been given. Many of the newer models have global navigational satellite system or GNSS such as GPS and GLONASS. You can find drones that use GNASS or fly without the need of a satellite. Take for example the DJI drones – you can fly them using GPS & GLONASS or ATTI (a mode which doesn’t use satellite navigation). The ability of the drone to navigate its surrounding is very important especially when it comes to it being able to perform tasks such as building 3d maps, surveying landscape or for search and rescue missions.
