This allows for more industrial uses such as inspecting cell towers or wind turbines to get a very detailed look at structures, wires, modules and components to detect damage. The Zenmuse is compatible with DJI Matrice range of drones.

The no fly zones are regulated and categorized by the Federal Aviation Authority (FAA).  Manufacturers can change the no fly zone drone technology using UAV firmware updates.

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.

There are various applications, which allow you to configure components of drones such as calibration of the IMU and the rotation of the drone motors.

The fast pace of UAV drone technological innovation is tremendous.  I’ve included these latest drone technology advancements in the below article.  So this article is right up to date including all links.

ToF depth ranging camera sensors can be used for object scanning, indoor navigation, obstacle avoidance, gesture recognition, tracking objects, measure volumes, reactive altimeters, 3D photography, augmented reality games and much more.

Up to a few years ago, much of the technology from military drones made their way into the consumer and business drones.

Drones such as the DJI Mavic use integrated controllers and intelligent algorithms to set a new standard for wireless high definition image transmission by lowering latency and increasing maximum range and reliability.

Allows the UAV drone and remote control system to know exactly its flight location. A home point can be set and this is the location the drone will return to, if the drone and the remote control system stop connecting. This is also known as “fail-safe function”.

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.

One of the most popular drones on the market is the DJI Phantom series.  These drones are very popular with professional aerial cinematographers.

When the compass is calibrated, it then seeks the location of GPS satellites. When more than 6 are found, it allows the drone to fly in “Ready To Fly” Mode.

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.

In the past few months, more new and highly advanced drones such as the DJI Mavic Mini, Mavic 2, Mavic Air 2, Phantom 4 Pro V2.0, Yuneec Typhoon H3 and Autel Evo 2 have come to the market.

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.

The RQ-4 Global Hawk is a high altitude, long-endurance unmanned aircraft system with an integrated sensor suite, which provides intelligence, surveillance and reconnaissance (ISR) capabilities worldwide.

Sensor fusion is software, which intelligently combines data from several different sensors such as a thermal camera and a regular RGB camera sensor for the purpose of improving application or system performance. Combining data from multiple sensors corrects the errors from individual sensors to calculate accurate position and orientation information.

The Electronic Speed Controllers signal to the drone motors information on speed, braking and also provide monitoring and fault tolerance on the drone motors.

DJI have a huge command of the consumer and professional drone market.  Here are the latest advanced UAV drones with patented technologies are the following;

Other, slightly older UAV drones such as the DJI Mavic and Phantom 4 Pro, can transmit live video up to 4.3 miles (7 km).  The Phantom 4 Pro and Inspire 2 use the latest DJI Lightbridge 2 transmission system.

This is a wireless communication device which generally operate within the 2.4 GHz frequency. It is used to extend the range of communication between the smartphone or tablet and the drone in an open unobstructed area.

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 Gyroscope is a component of the IMU and the IMU is an essential component of the drones flight controller. The flight controller is the central brain of the drone.

Having an excellent quality video software is essential for post processing. Most of the latest drones can film in Adobe DNG raw, which mean that all the original image information is retained for later processing.

Quite a few of the latest small UAV drones such as the DJI Mavic Air 2 take VTOL to the next level and can be launched from the palm of your hand.

The DJI Mavic 2 Pro and Mavic 2 Zoom have obstacle sensing on all 6 sides. The Mavic 2 uses both Vision and Infrared sensors fused into a vision system known as omni-directional Obstacle Sensing.

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.

FPV means “First Person View”. A video camera is mounted on the unmanned aerial vehicle and this camera broadcasts the live video to the pilot on the ground.  The ground pilot is flying the aircraft as if they were on-board the aircraft instead of looking at the aircraft from the pilot’s actual ground position.

The flight control system communicates with a PC Assistant through a micro-USB cable. This allows configuration of the UAV and to upgrade the drone firmware.

For example, multispectral sensors on drones can create Digital Elevation Maps (DEMS) of land areas to provide precision data on the health of crops, flowers, fauna, shrubs and trees.

Drone manufacturers release firmware upgrades to fix bugs and add new features to the aircraft, remote control unit or software if it is used to fly the drone.

Many UAV drone ground controllers use FPV (First Person View), which transmit the video from the drone to the controller or mobile device.

The drone has a multi-band wireless FPV transmitter built in along with an antenna.  Depending on the drone, the receiver of the live video signals can be either the remote control unit, a computer, tablet or smartphone device.

The Walkera Voyager 4 comes with an incredible 18 x zoom camera.  The 18 times optical zoom camera on the Voyager 4 has unobstructed 360 degree filming.  It can film in 4k at 30 frames per second. The  high definition image transmission system uses a 3-axis brushless stabilization gimbal technology.

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.

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.

On the DJI Phantom 3, this is the wireless communication device using the 5.8 GHz frequency band. Remote controls systems are also known as ground control. The drone and the ground control should already be paired when it leaves the factory.

Most of the UAV 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.

In the past few years, we have seen massive investment in drones especially in the business and consumer drone sector. Drone technology and innovation has really leaped forwarded in the past few years.

There are many different technologies used to track drones and you can read further on the best follow you drones here along with their tracking systems.

For more information, read this article on how drone motors and propulsion system work, which includes very informative videos.

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.

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. The exact meaning of VTOL is “Vertical Take-Off and Landing”.

A very simple description of a UAV drone is that it is a flying computer with a camera or sensor attached. Like computers, drones have firmware software, which send commands to the physical components in the aircraft or remote controller.

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.

The Voyager 5 includes redundancy systems such as dual GPS, dual gyroscope and 3 battery systems. It also has optional thermal infrared and low light night vision camera.

Below, we discuss UAV technology on the most popular drones on the market, which have all the latest drone technology.  Most UAV drones will have very similar systems incorporated.

UAV drones are equipped with different state of the art technology such as infrared cameras, GPS and laser (consumer, commercial and military UAV). Drones are controlled by remote ground control systems (GSC) and also referred to as a ground cockpit.

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.

DJI later released the Zenmuse Z30 camera. This powerful Zenmuse Z30 is an integrated aerial zoom camera has a 30 x optical and 6 x digital zoom for a total magnification up to 180 x.

DJI released the Zenmuse Z3, which is an integrated aerial zoom camera and is optimized for still photography.  The Zenmuse Z3, which had a 7 x zoom made up of 3.5 x optical and 2x digital lossless zoom creating a 22 to 77 mm equivalent focal length range, making it ideal for industrial applications.

At CES a few years back, a company called Ambarella announced the H22 chip for cameras in drones. This H22 chip allows the camera to film in 4k HD video and includes electronic image stabilization, removing the camera gimbal.

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 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.

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.

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.  On a quadcopter, the motors and propellers work in pairs with 2 motors / propellers rotating clockwise (CW Propellers) and 2 motors rotating Counter Clockwise (CCW Propellers).

The exceptionally fast growth and development of the drone racing league would not be possible without FPV live video transmission technology.

When the quadcopter is first switched on, it searches and detects GNSS satellites. High end GNSS systems use Satellite Constellation technology. 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 earlier drones used cameras, which were not fully suitable for aerial filming.  These aerial shots had barrel distortion because of the wide angle lens.

These educational drones are very reasonably priced and have everything to build and code a drone.  You can learn about these top educational drones here.

These drones uses their vision systems, detection sensors, GNSS systems, flight controllers, central processing and specific software to be able to track their subject with 100 accuracy.

In order to increase flight safety and prevent accidents in restricted areas, the latest drones from DJI and other manufacturers include a “No Fly Zone” feature.

One of the most exciting drone technologies is the ability to track subjects (people, vehicles, boats), particularly in the area of outdoor sports such as running, cycling, skiing etc.  The latest drones with excellent tracking abilities is the Mavic 2 and also the latest Skydio 2 where it’s tracking is so good that it never loses contact with the subject it is tracking.

There are terrific drones, drone kits, along with online material, which show you how to build and code UAVs.  There are lots of programming languages, which are very easy to learn such as Scratch, Swift, Blockly and Tynker to code a drone. You can also program drones using text based languages such as Python and JavaScript.

Older drones from the other top manufacturers can’t fly as far as DJI drones.  However, products such as range extenders are very popular, which can push the distance even further.

They receive data from the flight controller and the electronic speed controllers (ESC) on the drone motor direction to either fly or hover.

Below I have 2 videos which explain more about drone technology.  The first video is by top UAV scientist Raffaello D’Andrea who gives us a terrific understanding of the software science behind UAV technology.  He discusses the science of algorithms, control theory and model based design.

The gimbal allows the camera to tilt while in flight, creating unique angles.  More importantly, the gimbal reduces camera vibration. These are mostly 3 axis stabilized gimbals with 2 working modes. Non-FPV mode and FPV mode.

FPV allows the unmanned aircraft to fly much higher and further than you can from looking at the aircraft from the ground.  First Person View allows for more precise flying especially around obstacles.

Capturing high resolution images on a stabilized drone is very important. Using top photogrammetry software to process the images into real maps and models is just as important.  Some of the top drone mapping software is as follows;

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.

Live video and maximizing the range of the transmission is fascinating drone technology. Here is a tremendous article entitled “Understanding FPV Live Video Transmission“.

Here is an excellent article, which covers the top 10 military drones with many of the top military drones being manufactured by General Atomics Aeronautical Systems.

What is a drone and how do drones work is answered here in this easy to understand article. UAV drone technology is constantly evolving as new innovation and big investment are bringing more advanced drones to the market every few months.

Personally, I am much more fascinated by the drone technology and its uses in everyday life to assist with saving lives in search and rescue, site surveying by many  sectors, aerial cinematography or just to fly for fun by the hobbyist.

In 2016, drones using Time-of-Flight (ToF) sensors came on the market.  ToF sensors, also known as “Flash Lidar” can be used on their own or with RGB and regular lidar sensors to provide various solutions across the sectors.

DroneDeploy is one of the leaders in the creation of 3D mapping software.  Their mobile app and Live Map is being used in various sectors for creating 3D maps and models. They have a specialized solution for the agriculture sector and their software will work with most of the latest drones.

Lidar, Multispectral and Photogrammetry sensors are being used to build 3D models of buildings and landscapes.  Low light night vision and Thermal vision sensors are being used on drones to  scan buildings and landscapes to assist in agriculture, firefighting, search and rescue.

The Dronecode Project is an open source, collaborative project which brings together existing and future open source unmanned aerial vehicle projects under a nonprofit structure governed by The Linux Foundation. The result is a common, shared open source platform for Unmanned Aerial Vehicles (UAV).

Over the coming years, drones will transform our cities, revolutionizing how people travel, how goods are delivered and how buildings look and are constructed.

UAV drones in many ways are like flying computers.  With an operating system, flight controllers and main boards with programmable code, they can also be hacked into.  Drones have been developed to fly around seeking other drones and hacking into the drones wireless network, disconnecting the owner and take over that drone.  However, there is some practical ways to protect your drone from hackers.

Drones have so many terrific uses.  When you mount a camera or sensor such as LiDAR, Thermal, ToF or Multispectral, then the range of uses for drones keeps expanding.  Here is an excellent list of drone uses.

For lidar and photogrammetry mapping, the UAV is programmed to fly over an area autonomously, using waypoint navigation. The camera on the drone will take photographs at 0.5 or 1 second intervals. These photos are then stitched together using specialized photogrammetry software to create the 3D images.

Most unmanned aircraft use Linux and a few MS Windows.  The Linux Foundation have a project launched in 2014 called the Dronecode project.

The Skydio 2 autonomy technology visualizes and calculates what’s happening around the drone. It can then intelligently predict what will happen next and will make accurate decisions multiple times a second.

In 2016, a new live video, which transmits over the 4G / LTE network, providing an unlimited range and low latency video was announced. This drone technology was released on the Sky Drone FPV 2 and comprises of a camera module, a data module and a 4G / LTE modem.

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.

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.
