What would take humans around years to reforest can be more efficiently completed via seed-planting drone technology. Finally, UAVs are becoming instrumental in historical conservation efforts. Drones are being used to map out 3D renderings of historical sites like Chernobyl, the ancient Greek sites of Ephesus, Turkey and Jewish cemeteries all over Europe.
The vantage point gives historical preservationists the ability to find clues about culture and architecture while using 3D imagery to recreate lost sites. How do you get medical supplies to people in hard-to-reach areas? What tool could you use to deliver organs for transplant patients? Drones are the answer to both of those questions. Right now, unmanned aerial vehicles are being used to deliver emergency medical supplies and cargo to off-the-grid communities in rural Alaska.
Drones are also being tapped to deliver donated organs to transplant patients. Just recently, history was made when a kidney was transported by a specially-made drone from one hospital in Maryland to the next in just under five minutes. This could cut down on the alarmingly slow rate at which donations usually arrive if they arrive at all.
Usually, organs are delivered via chartered or commercial flights. Drones can cut time down tremendously while offering a safer and secure method of organ transportation. Drones have been a boon for photographers who use UAVs to take expansive aerial photos. There are drones made specifically for photography that provide a new way to photograph some of your favorite destinations from above.
However, new government regulations have come into play that require those piloting drones for commercial purposes to earn a Remote Pilot Certificate by taking an aeronautical knowledge test. The exam consists of 60 multiple-choice questions, with topics including regulations to Unmanned Aerial System UAS rating privileges, limitations and flight operation, effects of weather on UAS performance, emergency procedures, airport regulations, decision making, maintenance and more.
To be eligible to take the exam, one must be at least 16 years old, be able to read, understand, speak and write English, and be in good enough physical and mental condition to fly a drone. Drones present several solutions to emerging and lingering challenges throughout industries, however, many have expressed concern over the potential negative impact that the growth of these devices presents. Because drones rely on cameras to operate, which often allow operators to take photos and record videos, many have shown discontent at being captured without their consent.
Since drones occupy airspace, with many able to reach heights rivaling those of a jet, concerns have been raised about drones causing or exacerbating disasters and emergency situations. Drones can often be hard to track on air traffic radars, presenting new obstacles for plane and helicopter pilots to navigate through while in flight. In some cases, the presence of a drone may even preclude emergency aircraft from providing assistance , like in wildfire-stricken parts of the American southwest.
Whether in the air or on the ground, all human-operated aircraft possess an inherent risk of crashing — even when they are unmanned. Drones operate on limited battery power at a time, possess propellers that spin quickly to provide lift and have the potential to fall from great heights, posing a large risk to people, property and the environment as the number of drones in use scales upward.
Drone Technology. Drones are being implemented in a variety of industries to carry out dangerous tasks or make monotonous tasks more efficient. What is a Drone? Payloads Drones, UAVs specifically, come in a variety of sizes and are capable of carrying payloads of equally variable sized payloads.
Data Links Data Links act as the transmission center that allow the drone to communicate with the ground operator while in flight. Drones come in a variety of shapes and sizes, which helps them to carry out specific tasks.
Types of Drones Single Rotor Helicopters Single rotor helicopters look exactly like tiny helicopters and can be gas or electric-powered. Multi-Rotor Drones Multi-rotor drones are usually some of the smallest and lightest drones on the market. Fixed Wing Drones Fixed-wing drones look like normal airplanes, where the wings provide the lift instead of rotors- making them very efficient.
Shark or Dolphin? The military isn't the only industry that uses drones. Today, UAVs can be found improving the efficiency and safety of almost every industry imaginable. Drone Uses Military Probably the oldest, most well-known and controversial use of drones is in the military.
Delivery Delivery drones are usually autonomous UAVs that are used to transport food, packages or goods to your front doorstep. Agriculture Drones have proven to be beneficial to the agriculture industry as well, presenting farmers with several ways to optimize their farms to maximize efficiency and reduce physical strain.

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 series.
These drones are very popular with professional aerial cinematographers. This Phantom UAVs are ideal to explain drone technology because they have everything in one package.
It includes the UAV, gimbal and camera. They also have some of the top drone technology on the market today. The fast pace of UAV drone technological innovation is tremendous. So this article is right up to date including all links. A typical unmanned aircraft is made of light composite materials to reduce weight and increase maneuverability. This composite material strength allows military drones to cruise at extremely high altitudes.
Drones are controlled by remote ground control systems GSC and also referred to as a ground cockpit.
An unmanned aerial vehicle system has two parts, the drone itself and the control system. The nose of the unmanned aerial vehicle is where all the sensors and navigational systems are present.
The rest of the body is full of drone technology systems since there is no space required to accommodate humans. The engineering materials used to build the drone are highly complex composites designed to absorb vibration, which decrease the sound produced.
These materials are very light weight. We also have plenty of information on the latest drone technologies from the newest drones on the market. There are plenty of links, where you can read deeper into various components of drone technology. For example, here is a terrific drone components overview article.
This gives information on the individual components seen in most drones. UAV drones come in a wide variety of sizes, with the largest being mostly used for military purposes such as the Predator drone. The next in size are unmanned aircraft, which have fixed wings and require short runways. These are generally used to cover large sections of land, working in areas such as geographical surveying or to combat wildlife poaching.
Next in size for drones are what is known as VTOL drones. These are generally quadcopters but not all. VTOL drones can take off, fly, hover and land vertically. Drones can fly in both GNSS and non satellite modes. When the quadcopter is first switched on, it searches and detects GNSS satellites.
Basically, a satellite constellation is a group of satellites working together giving coordinated coverage and are synchronized, so that they overlap well in coverage. Pass or coverage is the period in which a satellite is visible above the local horizon. The latest Mavic Air 2 technology can sense obstacles during automatic return to home.
The latest high tech drones are now equipped with collision avoidance systems. These use obstacle detection sensors to scan the surroundings, while software algorithms and SLAM technology produce the images into 3D maps allowing the drone to sense and avoid. These systems fuse one or more of the following sensors to sense and avoid;. The Mavic 2 uses both Vision and Infrared sensors fused into a vision system known as omni-directional Obstacle Sensing.
The DJI Mavic 2 obstacle sensing system is top drone technology. The Mavic 2 will sense objects, then fly around obstacles in front. It can do the same when flying backwards. Or hover if it is not possible to fly around the obstacle. In December , the Skydio 2 drone was released. This also has obstacle avoidance on all sides. It can then intelligently predict what will happen next and will make accurate decisions multiple times a second. The Skydio 2 quadcopter uses 6 x 4k cameras to build a 3D map of its surroundings, which will include trees, people, animals, cars, buildings and more.
Gyro stabilization technology give the UAV drone its smooth flight capabilities. The gyroscope works almost instantly to the forces moving against the drone, keeping it flying or hovering very smoothly. The gyroscope provides essential navigational information to the central flight controller. The inertial measurement unit IMU works by detecting the current rate of acceleration using one or more accelerometers.
The IMU detects changes in rotational attributes like pitch, roll and yaw using one or more gyroscopes. Some IMU include a magnetometer to assist with calibration against orientation drift. The flight controller is the central brain of the drone. Here is a terrific article, which covers gyro stabilization and IMU technology in drones. The propulsion system motors, electronic speed controllers and propellers are the drone technology, which move the UAV into the air and to fly in any direction or hover.
They receive data from the flight controller and the electronic speed controllers ESC on the drone motor direction to either fly or hover.
Top UAV drone motors and propulsion systems are highly advanced and include the following components;.
The Electronic Speed Controllers signal to the drone motors information on speed, braking and also provide monitoring and fault tolerance on the drone motors. For more information, read this article on how drone motors and propulsion system work , which includes very informative videos.
Nearly all drones have a Ground Station Controller GSC or a smartphone app, allowing you to fly the drone and to keep track of the current flight telemetry. Telemetry data showing on the remote controller many include UAV range, height, speed, GNSS strength, remaining battery power and warnings. Manufacturers can change the no fly zone drone technology using UAV firmware updates. When the compass is calibrated, it then seeks the location of GPS satellites. Facebook is using drones to provide Internet connections in remote locations.
In short, the drone industry is booming. You can take part in this dynamic growth by earning a drone technology degree from California University of Pennsylvania. It will also prepare you for Unmanned Aircraft Systems UAS Certification —an essential credential if you want a competitive career edge. Drones are becoming commonplace in both the commercial and non-profits sectors.
In the near future their use will be even more widespread. Here are some of the many ways unmanned aircraft can revolutionize how we get things done. Are you ready to take on an active role in the future of drones?
