INTRODUCTION

The goal of our project is to design a useful and fully functional

real-world product that is used to track the vehicle's location and

improve the security level

Combination of two Technologies: GPS and GSM

Exact position of the vehicle is tracked by GPS

Position of the vehicle in terms of latitude and longitude is access

by GSM modem located at remote location and displayed on

Google Earth

LITERATURE REVIEW

Vehicle tracking systems can now also be found in consumers vehicles as

a theft prevention and retrieval device. Police can follow the signal

emitted by the tracking system to locate a stolen vehicle

Most of the papers show two separate methodologies like GPS and GSM

for detecting vehicle theft. In some cases both of them are implemented as

a combine unit but there are some issues related to providing exact visual

location

Based on the current requirements, besides integrating both the

technologies, in our project we are providing a complete unit that monitor

and locate the vehicle, thereby ensuring complete security to the vehicle.

SYSTEM REQUIRMENTS

AERON GPS Module

SIM 300 GSM Module

AT89C51 Microcontroller

Serial Communication Unit(RS232)

On board devices

Web support for displaying location

GLOBAL POSITIONING SYSTEM

• GPS is a satellite-based navigation system made up of a network of 24 satellites

• Developed by the U.S. Department of Defence for military applications

• The first GPS satellite was launched in 1978.A full constellation of 24 satellites was

achieved in 1994.

• Each satellite is built to last about 10 years. Replacements are constantly being built

and launched into orbit.

• The satellites transmit signals that can be detected by GPS receivers located in your

vehicles and used to determine their location with great accuracy

HOW GPS WORKS

GPS satellites circle the earth twice a day in a very precise orbit and transmit

signal information to earth

GPS receivers take this information and calculates the user's exact location.

A GPS receiver must be locked on to the signal of at least three satellites to

calculate a 2D position (latitude and longitude) and track movement

GPS Receivers commonly used in most Vehicle tracking systems can only

receive data from GPS Satellites. They cannot communicate back with GPS or

any other satellite

A system based on GPS can only calculate its location but cannot send it to

central control room. In order to do this they normally use GSM networks

GLOBAL SYSTEM FOR MOBILE

• GSM Mobile communication system can be

intelligently used by electronic devices which can

collect some data and send it to the central place

using SMS or GSM data call.

• GSM is required in Vehicle tracking systems

because GPS system can normally only receive

location information from satellites but cannot

communicate back with them.

• Hence we need some other communication

system like GSM to send this location information

to central control room.

GPS RECEIVER

It receives the information

sent by satellite in terms of

latitude and longitude

the GPS receiver compares

the time a signal was

transmitted by a satellite with

the time it was received. The

time difference tells the GPS

receiver how far away the

satellite is

GSM MODULE SIM 300

• Sends and receives the SMS

with a portable SIM card

facility

• Communicate with controller

in serial mode

• Requires 12V/100mAmp

• Powerful AT Command set

AT COMMANDS

AT COMMAND FUNCTION

AT+CNMI Gives the indication of arrival any SMS

AT+CMGF Selects the data mode foe GSM module

AT+CMGR Read the incoming SMS

AT+CMGD Delete the SMS

AT+CMGS Send the SMS

AT+CMGW Write the SMS into memory

Security Applications

CONCLUSION

A real-time automobile tracking system via Google Earth is presented.

The system included two main components: a transmitting embedded

module to interface in-vehicle GPS and GSM devices in order determine

and send automobile location and status information via SMS.

The second stationary module is a receiving module to collect and process

the transmitted information to a compatible format with Google Earth to

remotely monitor the automobile location and status online.

The transmitted location of the vehicle has been accurately tracking. The

accuracy of estimated vehicle coordinates has been enhanced.

FUTURE SCOPE

Besides using GSM, it is possible to implement the system using GPRS

technique.

At the receiver end instead of using GSM module the information can be

possible to receive on internet

An additional setting could be implemented to interface the system to the

car’s alarm to alert the owner on his cell phone if the alarm is set off.

The automobile’s airbag system can also be wired to this system to report

severe accidents to immediately alert the police and ambulance service

with the location of the accident.

QURIES ARE INVITED

?

What's the signal?

GPS satellites transmit two low power radio signals, designated L1 and L2.

Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band.

A GPS signal contains three different bits of information - a pseudorandom code,

ephemeris data and almanac data.

The pseudorandom code is simply an I.D. code that identifies which satellite is

transmitting information.

Ephemeris data, which is constantly transmitted by each satellite, contains

important information about the status of the satellite (healthy or unhealthy),

current date and time. This part of the signal is essential for determining a position.

The almanac data tells the GPS receiver where each GPS satellite should be at any

time throughout the day. Each satellite transmits almanac data showing the orbital

information for that satellite and for every other satellite in the system.
