Introduction:
Bangladesh is a country in South Asia. It is bordered by India on all sides except for a
small border with Burma (Myanmar) to the far southeast and by the Bay of Bengal to the
south. Together with the Indian state of West Bengal, it makes up the ethno-linguistic
region of Bengal. Bangladesh is the seventh most populous country in the world.
Bangladesh face a number of major challenges, including widespread political and
bureaucratic corruption, economic competition relative to the world, serious
overpopulation, widespread poverty, traffic congestion, load shedding and an increasing
danger of hydrologic shocks brought on by ecological vulnerability to climate change.
Modern day people do not eager to go outside their home due to traffic congestion.
Because, most of the time they are stuck in the traffic jam in Dhaka city. The government
took some necessary step to control the traffic congestion, but they are not very effective.
Now, government decides that they will take the help of Global Positioning System
(GPS) to control the traffic congestion.
What is Global Positioning System (GPS):
The Global Positioning System (GPS) is a U.S. space-based global navigation satellite
system. It provides reliable positioning, navigation, and timing services to worldwide on
a continuous basis in all weather, day and night, anywhere on or near the Earth.
How it Works:
Generally GPS is made up of three segments: Space, Control and User. The Space
Segment is composed of 24 to 32 satellites in Medium Earth Orbit and also includes the
boosters required to launch them into the orbit.
That picture is a visual example of the GPS constellation in motion with the Earth
rotating.
The Control Segment is the composed of a Master Control Station, an Alternate Master
Control Station, and a host of dedicated and shared Ground Antennas and Monitor
Stations. The control segment has four parts.
They are:
1. A Master Control Station (MCS),
2. An Alternate Master Control Station,
3. Four dedicated Ground Antennas and
4. Six dedicated Monitor Stations.
The User Segment is composed of hundreds of thousands of U.S. and allied military users
of the secure GPS Precise Positioning Service, and tens of millions of civil, commercial
and scientific users of the Standard Positioning Service.
This is the picture of a typical GPS receiver with integrated antenna
GPS satellites broadcast signals from space that GPS receivers use to provide the
dimensional location (latitude, longitude, and altitude) and precise time.
Usefulness:
Now-a-days GPS is widely used for navigating, map making, land surveying, commerce,
scientific uses, tracking and surveillance. The precise time reference is used in many
applications including the scientific study of earthquakes and as a time synchronization
source for cellular network protocols. GPS has become a mainstay of transportation
systems worldwide, providing navigation for aviation, ground, and maritime operations.
Disaster relief and emergency services depend upon GPS for location and timing
capabilities in their life-saving missions. The accurate timing that GPS provides
facilitates everyday activities such as banking, mobile phone operations, and even the
control of power grids. Farmers, surveyors, geologists and countless others perform their
work more efficiently, safely, economically, and accurately using the free and open GPS
signals.
The main aspect of this project is ‘how GPS can be used to tackle traffic congestion of
Dhaka city. Dhaka is the capital of Bangladesh. Before we discuss about the traffic
congession of Dhaka city. First we took some quick look on Bangladesh. It is officially
known as the, ‘The People's Republic of Bangladesh’ is a country in South Asia. It is
bordered by India on all sides except for a small border with Burma (Myanmar) to the far
southeast and by the Bay of Bengal to the south. Together with the Indian state of West
Bengal, it makes up the ethno-linguistic region of Bengal. The name Bangladesh means
"Country of Bengal" in the official Bengali language.
Here we saw the flag and the coat of arms of Bangladesh. Bangladesh is the seventh most
populous country and is among the most densely populated countries in the world with a
high poverty rate. Bangladesh continues to face a number of major challenges, including
widespread political and bureaucratic corruption, economic competition relative to the
world, serious overpopulation, widespread poverty, and an increasing danger of
hydrologic shocks brought on by ecological vulnerability to climate change. The other
problems which cause the people of Bangladesh lot of headache are traffic congestion
and loadsheding.
Now the Government of Bangladesh decides to use the Global Positioning System(GPS)
to control the traffic congestion of Dhaka city. For applying the GPS in Bangladesh,
Bangladesh government first undertook a project named Bangladesh GPS Network
Installation, it is takes place in February 2007 in Bangladesh.
Figure 1 - PI Michael Steckler of Lamont-Doherty Earth Observatory inspects the
antenna mount. GPS station JURI is located at the Sagarnal Health Complex in the Sylhet
Division of northeastern Bangladesh.
Participants from Lamont-Doherty Earth Observatory, Dhaka University, and the
UNAVCO Facility installed 12 continuous GPS stations across eastern Bangladesh in
February, 2007. The project, aimed at understanding the deformation associated with the
Burma Arc subduction system, includes deployment of the GPS systems for 4 years and a
rotating network of seismometers. The Burma Arc setting is particularly unique due to
the large amount of sediment from the Ganges-Brahmaputra delta being incorporated into
the subduction system, which produces a rapid broadening the accretionary prism and
foldbelt. In addition, vertical velocities from the GPS data may allow for greater insight
into possible subsidence of the delta.

Each GPS site is equipped with a Trimble NetRS receiver and Trimble Zephyr Geodetic
antenna. The receivers are programmed to record observations at 15 second and 1 second
sampling rates. Due to the scarcity of bedrock and good sky view in Bangladesh, all of
the antennas were installed on reinforced concrete column buildings; monumentation
consisted of a 5/8" diameter stainless steel all-thread rod cemented into a hole drilled into
the roof (Figures 1 and 2). The height of the antenna above the roof ranged from 13-30
cm. Eleven of the stations were powered by AC power from the host building with a 100
Amp-hour battery back-up. The site at Barkhol, accessible only by boat across Kaptai
Lake, utilized solar panels and a custom designed solar panel frame (Figure 3), with 118
Amp-hours of battery back-up.
The GPS network is focused mainly in the Sylhet Division of northeast Bangladesh and
the remote Chittagong Hill Tracts of southeast Bangladesh.
The company generally provides GPS service in Bangladesh. They are very few in
number. They are Geoplan Bangladesh and GPS Integrated. In our project we discuss
about the GPS Integrated.
General Description about the Business:
GPS Integrated provides high quality GPS Tracking Products, GPS Tracking Services to
customers and businesses across the world. They offer a variety of tracking systems that
are ideal for personal tracking, Child Tracking, Elderly Tracking or business use like
Vehicle Tracking, Fleet Management, and Truck Tracking.
