Title: Global
Positioning System: Working and Applications
Abstract:The most promising
and fully operational GPS (Global
Positioning System) is a navigation system based on a group of 24
satellites
developed by U.S. Department of Defence. Every satellite sends data to
the
receiver in the form of signals, having some information about
satellite and
orbital information. This paper aims to discuss the potential of GPS as
constantly global communication medium and gives insights in terms of
its
business and military applications. It focuses on the architecture of
GPS, its
working, changing signal conditions and discusses its technical
applicability
and uses current advanced applications of GPS like vehicle tracking,
location-based services as a case study. Even in worst weather
conditions this
GPS system is used to find out exact location with respect to timing
information
anywhere on the surface of globe. The paper will also consider
different
weather and geographical conditions to prove the suitability and
compatibility
of the GPS. The paper will also compare GPS with other navigation
systems and
will discuss its advantages such as high precision and continuous
coverage.
