Abstract—There are two concerns with GPS systems. On one side, many people are becoming more aware of privacy issues that emanate from wide spread use of GPS enabled or similar systems. On the other, in absence of GPS systems emergency help is of great importance as location detection becomes not so easy. Thus, there is a need for location detection technique or a solution that not only helps in detecting location but relieves the person of the privacy concern. Such systems find widespread application in military and personal communications. In this paper, introduction to various well known systems is first presented, followed by existing location detection methods and technologies. The privacy issues are also highlighted. In order to address privacy, a location detection system is developed for a limited geographical area as a case study. The simplicity and security of data transfer are also addressed by encryption using special purpose microcontrollers. The standardization efforts for location identification are also summarized.
