A Review on Applications of GPS Technology

Abstract

Tracking living beings and devices using the Global Positioning System (GPS) has become prevalent and indispensable over the last few years. Applications range from national and military security to personal safety and comfort. This paper presents some of the recent application areas such as a general tracking system to locate lost and misplaced devices (and those that carry such devices), introduces an active alarming system for predicting a collision between two or more vehicles using GPS and IEEE 802.15.4 MAC/PHY specification compatible system on chip( show the correct position of the vehicle to the user on the basis of the location information sent by the GPS Device. A land vehicle tracking system which determines the position of land rover with a terminal with embedded GPS receiver or PCS phone and displays the position on a digital map, a GPS based system which monitors the movement of the earth?s surface by measuring precise position (within 5mm or less) of stations near active faults relative to each other. To help a driver move ahead safely, detecting other vehicles in vicinity proves to be of great help. With the help of GPS we are able to identify a possible collision the vehicle must acquire its positional knowledge with respect to others.
