What is drone?
Drone technology is constantly evolving as new innovation and big investment are bringing more advanced drones to the market every few months.
Unmanned aerial vehicle technology covers everything from 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.
One of the most popular drones on the market is the DJI Phantom 3.
The latest drones have dual Global Navigational Satellite Systems (GNSS) such as GPS and GLONASS.
Drones can fly in both GNSS and non satellite modes. For example DJI drones can fly in P-Mode (GPS & GLONASS) or ATTI mode, which doesn’t use GPS.
Highly accurate drone navigation is very important when flying especially in drone applications such as creating 3D maps, surveying landscape and SAR (Search & Rescue) missions.
Most of the latest drone have 3 types of Return to Home drone technology as follows;
Pilot initiated return to home by pressing button on Remote Controller or in an app.
A low battery level, where the UAV will fly automatically back to the home point.
Loss of contact between the UAV and Remote Controller with the UAV flying back automatically to its home point.
Smartphone App Featuring Ground Station Function
Most of the drones today can be flown by a remote controller or from a smartphone app, which can be downloaded from Google Play or the Apple Store. The app allows for full control of the drone.
Each manufacturer will have their own app such as the Go 4 app from DJI.
High Performance Camera
The latest drones from DJI, Walkera, Yuneec and other manufacturers now include cameras, which can shoot film in 4k video and can take 12 megapixel stills.
The earlier drones used cameras, which were not fully suitable for aerial filming. These aerial shots had barrel distortion because of the wide angle lens.
However, the latest 4k video drones such as DJI Mavic series, DJI Inspire 1, Phantom 3 Professional and Phantom 4 have a camera which is specifically designed for aerial filming and photography.
The best drone for professional aerial filming is the DJI Inspire 2 mounted with the DJI Zenmuse X7 camera. The Inspire 2 image processing system CineCore 2.1, records video at up to 6k in CinemaDNG/RAW and 5.2k in Apple ProRes when used with the Zenmuse X7 camera.
The Inspire 2 is used by Hollywood producers. In fact, the Inspire 2 filmed all aerial and ground shots in a short film called The Circle with cinematic quality.
Drones have found a vast number of applications in different sectors. They are no longer limited to just military uses, and different businesses are now investing in these devices for swifter and more responsive customer service. Perhaps someday we will see all of our parcels delivered by commercial drone.
The many uses for drones show no signs of slowing down anytime soon. From business, to military, to photography, to consumer use, to just plain using a drone for fun, there might be something in the world of drones for anyone. This is why this is such a fun area to keep your eyes on, and the technology might just keep surprising you!
