Architecture of Global Positioning System (GPS) GPS or Global
positioning system is a satellite based navigation system that
provides the exact location and time of an object at any place
in the globe in all weather conditions. This is one of the best
example of technological advancement in the field of science and
technology. The basic concept of GPS technology involves the
transmission of signals by the satellites that includes three
things: the time at which the message was transmitted by the
receiver, the orbital information and the general system health
and rough orbits of all GPS satellites. To run all the system of
GPS technology properly, highly advance architecture of GPS has
been developed that includes three major segments called the
space segment (SS), control segment (CS) and a user segment
(US). The first two segments i.e. Space segment and control
segment is being controlled and operated by the U.S. Air force.
The GPS satellites transmits the signals from the space which
are received by the dat
