What is Drone and how it works ?

VTOL Drones
Next in size for drones are what is known as VTOL drones.

Many of these are 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”.

There's a fair amount of disagreement about what to call drones.

Drones are rising in popularity. With more people using them, their functions have increased.

Many of the latest small drones such as the DJI Mavic Air and DJI Spark take VTOL to the next levela and can be launched from the palm of your hand.

You may think that you know everything about these Unmanned Aerial Vehicles. While this may be true, there are surprising facts about them that will leave your mouth hanging open. There are also some myths about them that need debunking.

The surveillance industry wants drones to be more cuddly, though. In Britain, manufacturers have suggested painting drones bright colors as a way to make them seem friendlier and less reminiscent of war zones, reports The Guardian. Because Big Brother is a lot more appealing wearing hot pink, quips Slate.

Many of the latest drones have dual Global Navigational Satellite Systems (GNSS) such as GPS and GLONASS.

UAVs are a recent phenomenon. These devices may be new to you, and you may require some insights.

Drones can fly in both GNSS and non satellite modes.

Drones are aerial vehicles that do not need piloting. Industry players term them Unmanned Aerial Vehicles or Remotely Piloted Aerial Systems. They have preprogrammed flight plans, and will fly in straight lines or circles. Many of them can hover in place as well.

The Air Force has 65,000 - 70,000 people working to process all of the data and footage it's currently collecting from drones

For example DJI drones can fly in P-Mode (GPS & GLONASS) or ATTI mode, which doesn’t uses satellite navigation.

Military or governmental organizations use them in less accessible areas, such as war zones. Some of them are light enough to launch by hand. Others, such as spy planes are bigger and take off with the guidance of transmitters.

Lt. Gen. James says the analysts' work includes "watching life in Afghanistan and looking for patterns," and that a Rand review suggested they need 100,000 people devoted to the task. The military hope is that better computer algorithms and software analysis can be developed to combat their drowning in data.

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.

Cape Canaveral is now a drone base. Since the space program is now on a death watch, it's good to know they've found a way to repurpose this base.

UAVs, first developed by the military in the 1990s, are a mind-blowing innovation. They spark curiosity and wonder. Quadcopter Arena presents a few myths and debunks them with a few drone facts.

The FAA Reauthorization Act calls for six drone test sites around the U.S.

To the military, they are UAVs (Unmanned Aerial Vehicles) or RPAS (Remotely Piloted Aerial Systems). However, they are more commonly known as drones. Drones are used in situations where manned flight is considered too risky or difficult. They provide troops with a 24-hour "eye in the sky", seven days a week.

One of them is that a model airplane is a drone. Drones are machines that fly without a pilot controlling them. In contrast, pilots fly model airplanes within their line of sight. A model airplane cannot move out of a pilot’s periphery of vision, which disqualifies it as a drone.

This is how they will ensure that drones are safe for use -- and have mastered the "sense and avoid" features that are so important to the FAA, so that a drone doesn't fly into a plane engine or crash into a home -- and how drones will more easily be making their way to your local police station.

The Coast Guard thinks that drones will increase their prosecutions by 95%.
