Introduction

The world is µflat¶ in the sense that globalization

has leveled the competitive playing fields

between industrial & emerging market countries.

In a world which is so heavily inter-connected,

information regarding the position & movements

of goods as well as people play a huge role in

deciding the quality, cost & efficiency of any

product or project.

This is why we have chosen a project which will

provide important data related to position &

speed of the object which is being tracked.



Tracking

Two types of tracking:

1. Active tracking

2. Passive tracking

In this project we have incorporated both,active & passive tracking.

Thus we can get the latest information in realtime & use the passive mode for analyzing theroute which was followed.



Technologies used

This project is divided into three parts:

1. Speed tracker : used for tracking the

speed of any moving objects.2. GPS tracker : refers to Global Positioning

System.

3. GSM : Global System for Mobilecommunication.



Gist of the Project

Data in our project refers to speed & position,

thus it is a data recorder.

A data recorder is an electronic device that

records data w.r.t. time or in relation to locationwith either a built in instrument , sensor or

external instruments & sensors.

They can record data on a 24-hour basis & can

be left unattended to measure & record theinformation.

Thus can be used in harsh & remote locations.



Features of data recorder

Small , portable

Battery powered & equipped with a

microprocessor

Internal memory for data storage & sensors

Can be interfaced with PC using software to

activate this.

Can be used as a stand-alone device havinglocal interface devices like keypad , LCD

Memory may be battery-backed static RAM ,

flash memory or EEPROM.

Description of Blocks

Microcontroller(89C52 series): The 89C52 is also In-application Programmable (IAP),

allowing the Flash program memory to be reconfiguredeven while the application is running.

The Flash program memory supports both parallelprogramming and in serial In-System Programming(ISP).

Parallel programming mode offers gang-programming at

high speed, reducing programming costs and time tomarket.

ISP allows a device to be reprogrammed in the endproduct under software control.





GPS : Satellite navigation system which accurately

determines the longitude, latitude, & altitude i.e. theposition of an object.

It provides a precise time reference required for telecommunication which is important for map-making& land surveying.

Position is calculated by timing the signals carefullysent by constellation of GPS satellites above theearth.

Each satellite continually transmits messagescontaining the time of message sending, a preciseorbit for the respective satellite, system health & roughorbits of all GPS satellites.



These signals travel at the speed of light through outer space, & slightly slower through the atmosphere.

The receiver uses the arrival time of each message to

measure the distance to each satellite, from which it

determines the position of the receiver i.e. theintersection of spheres.

The coordinates are converted to user friendly forms.

4 satellites are used to determine the position.





GSM :

GSM is a cellular network which means that 2 devices connectby searching each other in their immediate vicinity.

It operates in four different frequency ranges & the usage range

varies with country & band availability.

Time Division Multiplexing is used to allow 8 full-rate or 16 half-rate speech channels per radio frequency channel.

There are 8 radio time slots giving 8 burst periods grouped into

a frame known as TDMA frame.

Half-rate channels use alternate frames in the same timeslot. The gsm module is used for real time transmission of data

which is recorded.



Actual working� The main function of the system is to keep a

track of the position of a particular asset and itsspeed.

� The information regarding position and the

speed will be provided by the GPS module.� This data will be transmitted using the GSM

module for real time tracking from a remote

location.



� A speed limit will be set for the vehicle. Whenever the vehicle crosses this speed limit the

controller will be programmed to instruct theGSM module send an SMS regarding the breachof speed limit to an alternate number that can beof the vehicle owner or a control centre.

� Alternately if the owner/control centre wishes to

know the position or speed of the vehicle it cansend a msg to the GSM module and the GSMmodule in return will send the requiredinformation.

� At the same time the data will also be stored in

memory for analysis at a later stage.� Thus this system is an amalgamation of both

passive and active type of tracking.





� The product also displays the information which

is being sent to the driver of the vehicle.� This system also increases the security of a

vehicle as we can track the position of the stolenvehicle.

� Since our project uses GSM as thecommunication model, which is acceptedworldwide, we do not face roaming problems ascan be faced in CDMA modules which are not

accepted worldwide.



ApplicationsThis product can be used for the tracking of

practically anything and everything i.e. onwhatever object the module is present we can

detect it¶s exact location.

Examples for this will be:

� Vehicle Tracking

� In logistics to determine the location of goods,

whether they are in the process of transportation or

is in the warehouse� Live stock farming

� This system can be used to correct the path during

an expedition in case we are off track.



Future Scope

� We can interface geo-mapping soft-wares like

Google earth so that the information relayed by

the GSM module will be visualized in a

graphical form i.e. on maps� By using GPRS system the real time data can

be relayed through the internet to any remote

control station, thereby reducing the time

required to take corrective measures in case of

emergencies.
