ABSTRACT In this paper, details of design and applications of a navigation system known as GPS-GSM Integrator (G2I) are presented. G2I system consists of two modules namely In Vehicle Module (IVM) and Control Room Module (CRM). The IVM is microcontroller-based system equipped with GPS receiver and GSM modem. The CRM consists of a PC and GSM mobile phone. Drive tests are conducted with G2I (in different modes) for cellular coverage area determination, for development of reference GIS maps and for real time vehicle tracking. During these tests, the Received Signal Strength Indications (RSSI) of the cellular signal at various locations (latitude and longitude) in urban and rural regions are recorded and coverage area classification is done. The developed G2I system would be helpful for implementation of Location Based Services (LBS) INTRODUCTION The ability to communicate on the move has evolved remarkably since Guglielmo Marconi first demonstrated radio’s ability to provide contact with ships sailing the English Channel in 1897. Since then, the world’s communication market is witnessing a tremendous growth in the field of mobile communication and became the focus for the economic and industrial development of the society. Currently, while the telecommunications industries are deploying Third Generation (3G) systems worldwide, emerging nations postulate enabling technologies like implementation of wireless position data transfer services. Wireless position data transfer involves two steps. The first step is to determine the location of the Mobile User (MU) and... [continues]
