This proposed work is an attempt to design a tracking unit that uses the global positioning system to determine the precise location of a object, person or other asset to which it is attached and using GSM modem this information can be transmit to remote user. It can provide tele-monitoring system for inter-cities transportation vehicles such as taxis and buses. This system contains single-board embedded system that is equipped with GPS and GSM modems along with ARM processor that is installed in the vehicle. During object motion, its location can be reported by SMS message.

A software package is developed to read, process, analyze and store the incoming SMS messages. The use of GSM and GPS technologies allows the system to track object and provides the most up-to-date information about ongoing trips. If a password like SMS is sent by the owner, it automatically stops the vehicle or we can use it for different other work, it can provide real time control. This system finds its application in real time traffic surveillance. It could be used as a valuable tool for real time traveler. The current system can be able to provide monitoring process from anywhere.
The purpose of this system is to design and integrate a new system which is integrated with GPS- GSM to provide following feature: a) Location information, b) Real time tracking using SMS, c) track bus driver activity d) Communication is instantaneous therefore we can receive running report quickly. It is completely integrated so that once it is implemented in all vehicles, then it is easy to track vehicles any time.
When large object or vehicles were spread out over ground, the owner corporations often found it difficult to keep track of what was happening. They required some type of system to determine where each object was at any given time and for how long it travelled. Also the need of tracking in consumer’s vehicle use to prevent any kind of theft because police can use tracking reports to locate stolen vehicle. GSM and GPS based tracking system will provide effective, real time vehicle location, and reporting. A GPS- GSM based tracking system will inform where your vehicle is and where it has been, how long it has been.
The system uses geographic position and time information from the Global Positioning Satellites. The system has an “On- Board Module” which resides in the vehicle to be tracked. The On-Board module consists of GPS receiver, a GSM modem and ARM processor. It can provide tele-monitoring and management system for inter-cities transportation vehicles such as taxis and buses. [2] During vehicle motion, its real-time parameters such as location are reported by SMS message. The system takes advantage of wireless technology in providing powerful management transportation engine.
The use of GSM and GPS technologies allows the system to track vehicle and provides the most up-to-date information about ongoing trips. This system finds its application in real time traffic surveillance. It could be used as a valuable tool for real time traveler information, congestion monitoring, and system evaluation. [4] An intelligent, automated vehicle tracking system can resolve following problems such as, late arrivals to scheduled, improper use of company time and resources, unsafe driving habits, assigned routes, inefficient dispatching, and passenger’s dissatisfaction.
This can lead to better traffic flow modeling and a better understanding of driver behavior. This project includes various features like ingenuity, simplicity of design and easy implementation. It is completely integrated so that once it is implemented in all vehicles, then it is easy to track vehicle any time.Hardware framework for tracking system is shown in Fig 1. System contains high Performance ARM controller, a GPS, and GSM modem and overall system reside into a vehicle. A tracking system will provide effective real time vehicle location reporting .
Tracking system will inform where your vehicle is and where it has been, how longer it has been there. The basic function of in vehicle unite is to acquire, Monitor and transmit the position latitude, longitude, time to management center either at fixed interval or on demand. Microcontroller unit form the heart of tracking unit, which acquires and process the position data from the GPS module.
The GPS receiver of vehicle terminal receives and resolves the navigation message broadcasted by GPS position satellites, computes the longitude and latitude of vehicle coordinates, ransforms it into the GSM message form by GSM communication controller, and sends the message to monitoring center via the GSM network.

It Support instructions of AT commands. SIM300 can be integrated with a wide range of applications.
SIM300 is a Tri-band GSM/GPRS engine that works on frequencies EGSM 900 MHz, DCS 1800 MHz and PCS1900 MHz SIM300 provides GPRS multi-slot class 10 capabilities and support the GPRS coding schemes CS-1, CS-2, CS-3 and CS- 4. With a tiny configuration of 40mm x 33mm x 2. 85 mm, SIM300 can fit almost all the space requirement in our application. Therefore, the MCU can connect with GSM modules very expediently through serial interfaces.
