DATA COMMUNICATION AND NETWORK ROUTING

Introduction
The global position system is a communication technology which is produced by the
department of defence U.S. mainly, such kind of technique utilize between 24 and 32
average earth orbit satellites that lead the microwave motions from one location to
another. Such kind of technique enables the global position receiver in order to identify the
current location of the individual. This report objective is to highlights the fundamental
methods used to operate the GPS technique and its weakness and applications. There are
many applications of GPS system such as aviation, marine, military and many more which
will be discussed in this report. Moreover, the weaknesses and reliability of the data and
information will be evaluated from a better understanding.
1. Fundamental techniques or methods utilized to operate the GPS technology
The global positioning technique is utilized to identifying the location of the receiver and it is
used in many business industries and organizations. The main advantage of this technology
is that it delivers the continuous real time, 3D positioning and navigation process to
consumer (Novatel, 2018). The operating principle of GPS technology is very simple that is
every satellite system use two signals that involve carrier waves in order to identify the
pattern of receiver signal. It is observed that there are major three kinds of methods used
for operating the global positioning systems which are described below:
A. The user segment
B. The control process
C. The space technique
A. The space segment method
It involves around 24 satellite system in 12 hours near circular orbits at an altitude of 2000
kilo meter with the orbit angle 55 degrees. It is observed that minimum 4 satellite systems
can be viewed from any point on the surface of the earth. In which the data transmission
scheme controlled and maintained by using the stable atomic clock which is developed with
the help of satellite constellation with suitable satellite.
