Drone Vs. UAV (Difference)
In the twenty-first century, almost everyone has come to know about the term “Drone.” These will be more popular day by day as nowadays many people use these drones for multipurpose. But generally speaking, there is a variety of drones available in the market, from toys for children cost $30 to the most advanced weapons cost more than $10 million, but these all types of drones are not used for the same reason. So, the question which is asked by most of the users is why don’t they have different names?
So, don’t worry; you will get all the answers of your question here in this lecture, so for beginners, it is essential to note that every UAN is a drone, but every drone is not UAN. So here we will have a deep look at these concepts that drones’ popularity is increasing day by day. It is worthy to note that the definition of drones will be changed in the near future. So without any delay, we are going to define a drone.
What is a Drone?
While speaking of the term drone, the first thing to come to our mind that these are dangerous weapons that can fly without any control of man. The term drone can be used to describe a variety of vehicles; for example, there are submarines or some land vehicles that can be described under the drone category.
But we may understand your think tank, and you are thinking after listening to the drones that these are some flying objects (aircraft) that can be controlled without man control. The common thing that all the experts agree on is that these drones are operated without any pilot.
What is a UAV?
It stands for “Unnamed Aerial Vehicle,” and these are also some vehicles that can fly automatically. So, you might think it is a characteristic of a drone? Yes, you are right. These two terms are interchangeable, but the popularity gained by a drone is a million miles more than the term UAV.
But technically speaking, most of the professional persons in the industrial sector believe UAV need to have automatic flight capabilities, whereas drones do not have these capabilities. So it can be concluded that all UAVs are called drones, but not all drones are considered UAVs.
Difference between UAV and UAS
As a matter of concern, most people don’t know the terms drone, UAS, UAV. In the above paragraph, we have noted the difference between a drone and a UAV, and now it is time to compare UAV and UAS:
1. Difference between UAV and UAS
UAV and UAS are pretty different terms, but we have discussed that the definition of UAV and a drone is almost similar to most people. Still, most experts think that a UAV is more advanced than a drone and is used to shoot a video from certain heights.
Generally speaking, the UAV community doesn’t like to use the term drone to describe the UAV being sold in the market. But when we talk about the government and officials talk, they use the term drone and UAV to be replaced with UAS. It means that UAS is an all-defining term that may cover all the technical terms; the ground station for the pilot, support equipment and communication, etc., as we may conclude that the term UAS is used for advanced unnamed aircraft that are not allowed to use by civilians.
Speaking these terms, UAV and UAS are military terms that have been adopted to fit the civilian needs, and this, most of the time, is confusing. You are primarily familiar with the news, and you might have watched a drone that has covered and complete photage of the floods and forest fires in Australia, on the other hand, you might be familiar with the drone that has attacked the middle east, so it is fascinating here that we have used the same term for two different scenarios. This is why it is necessary to understand the clear sketch and have the knowledge to differentiate between UAV/drone and UAS.
2. What is UAS?
UAS (Unnamed Aerial System) is much more complex and advanced than UAV/drones; it is essential to note that all these three systems are very familiar, and it is pretty tricky for an average person to differentiate between them. UAS is a complete package that includes a GPS module, ground control, transmission system, HD quality camera system, and software. To keep it simple, we may see that a UAV/drone is a fundamental component of a UAS.
What does UAD stand for?
UAD stands for “Unnamed aerial devices.” These are used in aviation and aircraft studies to observe and tactical planning. This is used in the emergency to inform field assistance to the crew members to get alert. The UAD system is classified based on altitude range, weight, and endurance. This is one of the essential terms used by most drones/UAVs and UAS.
What is a quadcopter? May we mention this in the drone category?
Indeed. A quadcopter comes under the category of drones; these are a particular type of drone and are multirotor, it is a simple flying machine with four arms, and in each of its arms, there is a motor attached to a propeller. But this least not the last, as we know that multi-copters with six and eight arms are available in the marketplace, but all those work on the same principle as a quadcopter. Generally speaking, from its four arms, two rotors rotate clockwise while the other two rotate anticlockwise.
When we talk about stability, they are aerodynamically unstable. To fix it, you require a flight computer to convert your input commands into the command that changes the RPMs of the propellers to produce a particular desired motion. When we talk about its similarity with a helicopter, these both are pretty different from each other in the way they generate lift and control forces.
Simply for understanding the basics of aircraft, the lift is generated by wings, but on the contrary, in the case of the quadcopter, the lift is generated by propellers. A helicopter utilizes its main rotor to generate lift and can vary the pitch of the rotor blades to generate control forces.
Generally speaking, the quadcopter concept is not new in the modern world; the first quadcopter designs were managed to see in the early 1930s, but these early designed quadcopters have not enough performing abilities, a high level of instability and require plenty of pilot inputs, etc.
What’s Next for the UAV Lexicon?
Drones or UAVs are still a relatively new field. We can expect that the language surrounding them will evolve over the coming years. There are references to drones using the term “RPA” which stands for Remote Pilot Aircraft. This is done to distinguish high-level drones that require extensive training or experience from casual models meant for recreational flight.
Although “RPA” is a well-known term, it has not been widely used in its original meaning. Despite being interchangeable, “RPA” is often still used interchangeably with “UAV”.
The simple term “drone” is good for casual conversation, news reports, and articles. Most people associate the term with a multicopter drone. This perception is likely to reflect reality, given the popularity of multi-copters.
When discussing technical matters, however, it is important to distinguish between UAVs and UAS. The drone, while it is a part of the UAS, is just one component of a larger ecosystem that includes software, hardware, skills, and human input.
Final words:
Many types of aircraft are available nowadays in the market. In the technology field, almost a decade ago, most people were very well aware of just those types of drones used by the military services to counter the terrorist attacks on civilians.
But now, after 2010, the term drone is ubiquitous and almost know to every person on the globe. As discussed in the introduction, a $30 drone is accessible by a six-year-old child in playing a game or shooting a video.
