The algorithms also help keep the drone within the operator’s line of sight at all times. As drones communicate through smart-phone apps, they can access safe-flight instructions online. These instructions take into consideration the altitude and GPS location of the drone.

Another reason for their popularity is the effective and fun use of cameras. A majority of drones feature high-definition cameras which can capture video as well. The videos and images captured by these devices have made them viral, catapulting them into the top positions on many peoples’ wish lists.

Brief History

UAV or drone innovations began in the 1900s and mainly concentrated on providing effective practice targets for training military personnel. The development of drones carried on during World War I, with the Dayton-Wright Company inventing pilotless torpedoes designed to explode at preset times.

In 1916, the first attempt at a power-driven drone was by AM Low when he developed the Aerial Target. Some advances came after the World War I, which include the automatic plane developed by Hewitt Sperry.

In 1935, model-airplane enthusiast and film star Reginald Denny developed the first version of the scaled remote pilot vehicle.

More drones emerged, especially during the World War II to fly assault missions and train anti-aircraft gunners. Nazi Germany also developed and deployed a variety of UAVs during the war. In 1955, companies such as Beechcraft provided their unique Model 1001 for the use of US Navy.

With the miniaturization and maturity of various applicable technologies, especially in the late 1980s and early 1990s, U.S. military started taking more interest in drone technology. In the late 1990s, the Department of Defense offered contracts to AAI Corporation.

The US Navy purchased the AAI Pioneer drone that was developed jointly by AAI and Malat (an Israeli company). A lot of these aircrafts took part in the Gulf War in 1991.

Uses Of Drones

As you are probably well-aware, many individual entrepreneurs, large and small companies are putting drones to great use. In the recent past, non-military UAVs have become a very accessible and inexpensive means to accomplish a variety of tasks. Some of the popular uses are:

Aerial Photography

Drones are part of both cinematography and sports photography. In 2014, drones were used in Sochi in the Winter Olympics for filming snowboarding and skiing events. Journalists are also considering the use of drones as they can gather information and footage that you can use for a live broadcast.


Farmers can use drones in a variety of ways for their benefit. Many people in the drone industry are of the view that agriculture represents a great opportunity for UAV technology. Drones can help save farmers plenty of money by timely identifying failing plants as well as take stock of crops.

Farmers can use drones in a variety of ways for their benefit.

Also, farmers can use the device to study and map the farmlands and their irrigation system. In these situations, using drones can help expedite the time-consuming process.

Moreover, you can equip drones to spray water and pesticides on crops. Farms with livestock can benefit from drones as they can be utilized to monitor animals and swiftly collect and track data regarding animal health.

Construction And Architecture

Construction contractors and architectural firms are deriving great benefits from drone technology. Similar to real estate professionals, architects can use footage and images of properties to develop 3D renderings of the buildings and structures they plan to build.

Architects can quickly and cheaply create aerial shots to place their architectural renderings, which can help them develop real-world concepts of the projects.

This unique ability is indispensable when it comes to developing accurate designs and models and understanding precisely how they can fit within relevant properties. During a construction project, getting access to these architectural plans is very useful to individuals responsible for the designing of the project.

Wildlife Tracking

The increasing availability of dependable and off-the-shelf drones has eased routine aerial surveillance, which used to be arduous in the past.

Although most drones are not specifically for conservation projects, many researchers are resorting to a couple of modification techniques to prepare drones better to keep track of wildlife, especially in harsh and severe environments.

Wildlife Tracking with drones.

For example, drones equipped with multi-spectral cameras can see across a much broader range of electromagnetic spectrum, which makes it possible to analyze both animal life and different types of vegetation.

Drones are discrete which allows them to monitor wildlife populations without alarming or disturbing them. This kind of monitoring effort can offer valuable insights into migration tracking, conservation efforts, and habitat management.

It is also helpful in flood assessment, which tends to be especially useful in the coastal areas. Drones can provide information on rare animal populations, as the technology can identify animal species in places that are hard to access.

Disaster Management

After a human-made or natural disaster, drones can provide a quick and easy way to collect information and thoroughly navigate debris using useful and portable technology that will not drown out any cries for assistance. Rescue teams in the area can easily deploy the technology to expedite their efforts.

As they feature radars and high-definition cameras, drones can easily provide rescue teams access to a wider and better field of view without having to waste resources on several manned helicopters.

Also, due to their small and compact size, drones can offer a close view of regions where large aerial vehicles are likely to prove inefficient or perilous.

Safety And Structural Inspections

Drones can also offer quicker access to top-notch and real-time visual inspections for different kinds of utility and energy companies who are required to inspect gas and oil pipelines, power lines, transmission towers, bridges, buildings and wind turbines.

Safety And Structural Inspections

They allow the inspecting team or officers easy access to the relevant information from a distant and safe position.

Moreover, inspections of complex infrastructures can benefit greatly from standard aerial monitoring. The unique ability to see things in three dimensions, detect metal strain and take thermal readings can considerably enhance the quality of infrastructure inspections.

Small drones, in particular, can get close and hover over objects to provide a greater level of detail which can improve performance.

Rescue And Search Efforts

As they feature various thermal sensors, drones can discover the whereabouts of lost or stranded individuals swiftly. These devices are especially useful inchallenging terrains or during nighttimes.

Especially in harsh conditions, many search and rescue missions are a tough battle against time. However, in these situations, drones can become your powerful tool as they are easy to deploy.

Apart from locating victims, you can use drones to drop supplies to a remote or otherwise unreachable location. For instance, you can use a drone to lower a GPS locator, walkie-talkie, medical supplies or water and food to stranded victims before rescue teams can extract them.

Types Of Drones

Drones come in a variety of shapes and sizes with many different features. Depending on the applications or needs, they have various sizes and designs. We will discuss the different types of drones according to their size, number of propellers, range, and equipment they carry.
