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.
