Abstract

This term paper is about commercial
and military drone technology. Its about how drones work and how they effect
the future by the technology and the progress they make in this earth and how
can we increase and make it a better place using the drone technology.
furthermore, the seven generations of drone technology well be shown  also well be having some information about the
camera in the drone and how its connected to the pilot because is an aircraft
without a human pilot on board  for that
cameras must be fixed.

 

 

Introduction

What is a drone ?

A drone, in a technological context, is an unmanned
aircraft. Drones are more formally known as unmanned aerial vehicles
(UAVs).  Essentially, a drone is a
flying robot. The aircrafts may be remotely controlled or can fly
autonomously through software-controlled flight plans in their systems working in connected with onboard sensors and GPS.

 

 

 

The two types of drones:

1.     The
Commercial drone technology which is used for Aerial photography  and filming One of the most popular drones on
the market is the DJI Phantom 3.  This
drone was very popular with professional aerial cinematographers

2.   the military 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. Each aircraft can stay
alert  for up to 17 hours at a time,
loitering over an area and sending back real-time imagery of activities on the
ground.

 

Sizes of drones

Drones come in a wide variety of sizes, with the
largest being mostly used for military purposes such as the Predator drone and
to the smallest which is used for commercial

 

·       
The
world biggest drone weights 16,000 pounds and 44 feet long the Avenger is now
the largest UAV in the U.S. arsenal Its Biggest and Fastest
Armed Drone Ever.

 

·       
  World’s
Smallest FPV (first person view) Drone which has the size of   4.3cm
x 4.3cm x 2.5cm and weight less than a gram.

 

 

Small Drones

The smallest size drones are mini drones. They can literally fit in the
palm of your hand, and some are even the size of a quarter. These drones range
in price from under $10 to over $60. Most are priced in the $15-$30 range they
most likely used in indoor areas

Medium-Sized Drones

A medium-sized drone is typically double the size of a miniature drone
or bigger. These drones come with more power, larger propellers, and additional
features. Many also come with low-grade cameras for taking aerial photos and
videos.

Professional-Grade Drones

Professional
pilots typically try to fly the best drones with the most advanced features. Commercial drones come
in the largest sizes. They also come with advanced features, like autonomous
flight modes, obstacle avoidance, on-the-fly camera setting adjustments, first
person view, and a whole lot more. This gives a professional pilot lots of room
to get the best shots possible and be creative at the same time. You can get
a professional
quality drone for $500 all the
way up to $13,000 or more for a custom rig.

 

Features

Radar Positioning,
the flight radar displays the current position and location of the drone
in relation to the pilot.
Return Home,
Exceeding the control range of the remote control will trigger a
‘Return-to-Home’ feature, meaning the UAV will automatically fly back to its
takeoff point and land safely.

·       
No Fly Zone Drone
Technology, in order to increase flight safety and prevent accidental flights
in restricted areas, the latest drones from DJI and other manufacturers include
a “No Fly Zone” feature.

Drones With Sensors

Multispectral,
Lidar, Photogrammetry and Thermal vision sensors are now being used on drones
to provide 3D models of buildings and landscape; Digital Elevation Maps (DEMS)
of land, and provide precision data on the health of crops, flowers, fauna,
shrubs and trees.

With Lidar and photogrammetry mapping, the drone
will be programmed to fly over an particular area using GPS waypoint
navigation. The camera on the drone will take photographs at say 0.5 or 1
second intervals.  These photos are then stitched together using
specialized software to create the 3D images.

–      A multispectral image is one
that captures image data within specific wavelength ranges across the
electromagnetic spectrum

–      Lidar is a remote sensing method used to examine the
surface of the Earth.

–      Photogrammetry is the process of deriving metric information about an object
through measurement made on the photograph of the object.

–      Thermal vision sensors is essentially a heat sensor that is
capable of detecting tiny differences in temperature. The device collects
the infrared radiation from objects in the scene and creates an
electronic image based on information about
the temperature differences.

 

 

Drone Technology progress

Drone technology is constantly evolving, day by
day drones are becoming more and more useful future of drones is getting better
and better, drone technology has seven potential generations.

·        
Generation 1: basic aircraft
which is remotely controlled.

·        
Generation 2: better design, fixed cameras and manual
piloting control with also video recording camera.

·        
Generation 3:  HD video camera
fixed, safety mode fixed, assisted drone control, two axis gimbals.

·        
Generation 4:  better video
camera 1080P HD, improved safety modes and improved obstacles avoidance,
autopilot modes fixed, Three-axis gimbals.

·        
Generation 5: 4K camera video,
intelligent piloting modes applied, 360° gimbals.

·        
Generation 6: Professional camera
suitable for commercial but not fully suitable, automated safety modes with
more technology, fully automatic piloting.

·        
Generation 7: fully suitable
for commercial, design with the lightest materials to be easier to flight, fully
and complete automatic safety modes, auto action (takeoff, land, and mission
execution) with one button.

 

 

Uses of Drones

 

·       
Fishing

Drone fishing may sound not possible at all , a
video was released  a giant fish has been
captured using a drone where they have placed their bait 100 meters off the
beach and many people had followed this trend due to that there’s now a drone
manufactured just for fishing called the AeroKontiki.

 

·       
Surfing

This must be one of the coolest ways an automaton has ever been utilized.
Freefly delivers substantial automatons that are waterproof and can convey 20
pounds. These automatons are fabricated for the media however as opposed to
conveying a camera, their most recent automaton, ALTA 8, was furnished with a
rope to pull a surfer. The automaton costs $18,000 yet certainly presents
another route for surfers that doesn’t rely upon great waves.

 

·       
Fire Fighting

Fighting a raging fire is one of the toughest jobs in the public service
world. Firefighters are often forced to rush into a blaze, having no idea of
the scope of it. Lately, the use of drones by fire departments and police
agencies has grown across the globe. An aerial view from a drone help
firefighters figure out the size of the fire and develop tactical methods
accordingly.

 

·       
Shipping/
Delivery

Dones can be used to deliver small packages,
pizzas, letters, medicines, beverages etc. at short distances

 

 

·       
Journalism,
Filming and aerial photography

 Drones are starting to be used in sports photography
and cinematography. They were used in the 2014 Winter
Olympics  for filming skiing
and snowboarding events due to difficulty in recording these kinds of sports.

 

·      
uses of drone in
ancient architectural sites

Drones
can be manufactured in very small sizes and due to this, drones can reach
places humans cant.

As
of right now, drones are being prepped to enter tight spaces into The Pyramids
Of Giza so as to learn things of the Pyramids. We weren’t able to enter this
space due to it being so small, but with the help of drones we can enter this
place without causing any structural damage to the Pyramids.

 

 

 

 

 

               

Usage of drones over the years

          

 

Over the past few years, drones have become central
to the functions of various businesses and governmental organizations.
 drones are proving to be extremely beneficial in places where man cannot
reach or is unable to perform in a timely and efficient manner. Increasing work
efficiency and productivity, decreasing workload and production costs,
improving accuracy,  It’s a technology
that everyone is benefiting from . Whether drones are controlled by a remote or
accessed via a smartphone app, they possess the capability of reaching the most
remote areas with little to no manpower needed and require the least amount of
effort, time, and energy. This is one of the biggest reasons why they are being
adopted worldwide, especially by these four sectors: Military, Commercial,
Personal, and Future Technology

 

Advantages

·       
Surpassing the
traffic.

·       
Used in dangerous environment.

·       
Environment friendly.

·

·       
Filming wildlife
has become easier.

·       
Uses in all spheres.

 

Disadvantages

·       
Weather – drones
can run into physical barriers such as wind, birds and air traffic.

·       
Domestic drones
violate the right to privacy.

·       
Easy to shoot down.

·       
Limited battery
power.

·       
Too small for
transportation of materials.

·       
GPS signals tends
to drop between tall buildings.

 

Conclusion

After looking at multiple articles and going through
numerous references, I realized that over the coming years we will see an
increase in the production and usage of drones , the government is getting more
involved with drones such as firefighting department and aerial surveillance
for traffic monitoring . Furthermore, tv shows , movies and professional
cameramen are now using drones for capturing scenes that are not possible for
human beings to do by themselves such as high aerial videography. However, from
the seven generation of drones we can notice the development and the steady
progress of technology in this sector and this will lead to many opportunities
in the future.
