Cost Effective GPS-GPRS Based Object Tracking System
[attachment=16477]

I. INTRODUCTION
A good number of tracking systems had so far been
developed with a wide range of tracking facilities [1]–[6].
But the operation cost of most of these systems is higher
which prevents from widespread use. On the other hand, the
rate of car theft, asset theft, child kidnapping in many
countries are increasing at a higher rate [7]. The objective of
this research is to reduce the cost of the tracking system using
the latest technologies and making it available to the common
people.


II. SYSTEM OVERVIEW
The system has two parts – the tracking device and the
database server as shown in Figure 1 below. The device is
attached with the moving object and gets the position from
GPS satellite in real-time. It then sends the position
information with the International Mobile Equipment
Identity (IMEI) number as its own identity to the server.


III. HARDWARE SPECIFICATION
We need a module which is compatible with
850MHZ/900MHz/1800MHz/190OMhz frequencies of
cellular networks. Telit GM862-GPS GPS/GPRS is the
module we have selected for this system shown in Fig 2. This
device is capable of working in any GSM network around the
world.


VI. CONCLUSION
This paper presents a low cost tracking system using GPS
and GPRS of GSM network, suitable for wide range of
applications all over the world. The combination of the GPS
and GPRS provides continuous and real time tracking. The
cost is much lower compared to SMS based tracking systems.
Free Google map and the use of HTTP protocol as data
sending method reduces the monthly bundle cost for the
individual user and also for the small business owner. It is
expected that the full implementation of the proposed system
would ultimately replace the traditional and costly SMS
based tracking systems.
